Hire data engineers
in India
Senior data engineers ready in 48 hours. Build ETL and ELT pipelines that don't break, warehouses that answer queries in seconds instead of minutes, and streaming platforms that show you what's happening right now, at 60 to 75% less than local rates.
What our data engineers build for you
Every company says it wants "better data." What that means in practice is six fairly specific jobs. Here's what our engineers actually ship, and where a neighboring specialist picks up the work.
ETL and ELT pipelines
Pipelines that pull data out of your product database, CRM, billing system, and third-party APIs, clean and reshape it, and load it into your warehouse on a schedule you can set your watch by. Built with retries, alerting, and backfill support, so a failed run at 3 AM does not mean a corrupted dashboard at 9.
Data warehouse design
Dimensional models on Snowflake, BigQuery, or Redshift, with a partitioning and clustering strategy chosen for the queries your BI tool actually runs, not a generic best-practice checklist. Cost and query speed get tuned together, since the two usually trade off against each other.
Real-time streaming pipelines
Kafka or Kinesis pipelines that move events, a signup, a payment, a sensor reading, into a system that can react within seconds. Built for fraud detection, live operational dashboards, and anything where "we'll see it in tomorrow's report" is too slow to matter.
Lakehouse architecture
Delta Lake or Apache Iceberg on S3, GCS, or Azure Data Lake Storage, giving you cheap storage for raw and semi-structured data with the schema enforcement and time-travel a plain data lake never had. This is usually the layer that feeds a data science or ML team their training data.
See the specialist page →Legacy data platform migrations
Moving off an aging Hadoop cluster, an overloaded production database being used as an analytics source, or a patchwork of spreadsheets and cron jobs, onto a modern cloud warehouse, one pipeline and one stakeholder group at a time, with the old and new systems running in parallel until the cutover is safe.
See the specialist page →Analytics and reporting infrastructure
The semantic layer, metrics definitions, and dbt models that sit between raw tables and the dashboards your executives actually look at, so "revenue" means the same number in every report instead of five slightly different ones depending on who built the query.
See the specialist page →What a senior data engineer actually does
Writing a SQL query is the easy part. What separates a senior data engineer from someone who has read the docs is judgment about the parts nobody sees until they break: what happens when an upstream API changes a field name, what a pipeline should do when yesterday's data never arrived, and whether a transformation belongs in the warehouse, in a Python script, or nowhere near either.
ETL versus ELT, and why the order matters
Older pipelines transform data before loading it, ETL, because storage and compute were both expensive and you could not afford to load raw junk into a warehouse. Cloud warehouses flipped that math. Now most teams load raw data first and transform it inside the warehouse, ELT, using the warehouse's own compute and a tool like dbt to do the reshaping in SQL. A senior data engineer knows when to break that default, heavy transformations before loading still make sense when the source system needs protecting from a large read, or when sensitive fields need to be masked before they ever land in a shared warehouse.
Spark and PySpark for the data that doesn't fit on one machine
Most transformation work runs fine as SQL inside a warehouse. Apache Spark and PySpark come in when the job is too large or too irregular for that, joining billions of rows across files, processing unstructured logs, or running the same transformation logic across both batch and streaming jobs. A senior engineer reaches for Spark when the data volume actually demands distributed processing, not as a default, because a Spark cluster that's solving a problem dbt could have solved in SQL is money and complexity spent for nothing.
Airflow, orchestration, and the DAG as a map of dependencies
A pipeline is rarely one job. It's a chain: extract from five sources, wait for all five, transform, load, then trigger a downstream dbt run and a Slack alert if anything failed. Apache Airflow, or lighter alternatives like Prefect and Dagster, express that chain as a DAG, a directed graph of tasks with dependencies, retries, and scheduling built in. A good data engineer writes DAGs that fail loudly and specifically, so when something breaks at 2 AM the alert says which table and why, not just "pipeline failed."
dbt and transformation as version-controlled code
dbt (data build tool) took the transformation step, which used to live in a folder of undocumented stored procedures nobody wanted to touch, and turned it into SQL models with tests, documentation, and a dependency graph, checked into Git like application code. A senior engineer writes dbt models that are modular, a staging layer that cleans raw data, an intermediate layer that joins it, and a mart layer that exposes clean, tested tables to whoever is querying them, rather than one 400-line query that does everything and that only its author understands.
Streaming, Kafka, and data that can't wait for the next batch job
Batch pipelines run on a schedule, hourly, nightly, and that's fine for most reporting. Streaming exists for the cases where an hour is too slow: fraud detection, live inventory, operational dashboards a support team is actually watching. Apache Kafka is the backbone most teams reach for, with Kafka Streams or Spark Structured Streaming doing the processing on top. A senior engineer treats streaming as a deliberate architectural choice, not a default, because it adds real operational complexity that a nightly batch job doesn't have.
Warehouses, lakes, and picking the right one
Snowflake, BigQuery, and Redshift are warehouses, structured, fast for SQL analytics, and priced by storage and compute in ways that reward good partitioning. Data lakes on S3, GCS, or Azure Data Lake Storage are cheaper and handle unstructured or semi-structured data the warehouse would choke on. Delta Lake and Apache Iceberg add schema enforcement and time-travel to a plain data lake, closing most of the gap with a warehouse, which is where the term "lakehouse" comes from. A senior engineer picks based on the query patterns and cost profile you actually have, not the platform with the loudest marketing that quarter.
SQL and Python as the two languages that never go out of style
SQL runs almost everything inside the warehouse, dbt models, ad hoc analysis, data quality checks. Python handles the parts SQL can't: custom extractors for APIs that don't fit a standard connector, orchestration logic in Airflow, and Spark jobs. A senior data engineer is fluent in both, writes SQL that a query planner can actually optimize instead of fighting it, and writes Python that a teammate can read six months later without a walkthrough.
Data engineer versus data scientist versus ML engineer, in practice
A data engineer builds the pipes: reliable pipelines, a clean warehouse, and infrastructure that a data scientist can query without wondering if the numbers are right. A data scientist takes that clean data and answers questions with it, builds a model, tests a hypothesis, mostly in notebooks, with less concern for uptime. An ML engineer takes a model that works in a notebook and puts it into production, serving predictions at the reliability standard a data engineer already holds for pipelines, often working alongside an MLOps engineer who owns the deployment and monitoring layer underneath it. Get the order wrong, hire a data scientist before the pipelines exist, and you get a brilliant analyst re-writing the same extraction script every week instead of doing analysis. What "good" looks like across all three roles is a stack where each person trusts the layer below them. Every engineer we place is reviewed against that bar in a live technical interview before you ever see their profile.
Technologies our data engineers use daily
Fluent in the core data-engineering stack, and just as comfortable in the cloud-native tooling that turns a pipeline design into something that runs unattended.
Why hire data engineers in India
Data engineering is unglamorous, high-stakes work, and India has been quietly building this exact bench for two decades of enterprise data-warehousing and BI projects. Here's the case in numbers.
The cost math for a data engineering team
A data engineer with a couple of years behind them starts around $1,800 a month through TechTeamsOnline. Mid-level runs about $2,500, senior about $3,200, and a data engineering lead who owns your platform architecture runs about $4,500. Compare that to the US, where a senior data engineer typically costs $140,000 to $185,000 a year, north of $11,000 a month on its own, and Stack Overflow's 2025 survey puts a US engineering manager's median pay at $200,000 against $52,000 in India, close to 4x. Put together a five-person data engineering team here and you land near $11,000 a month total, against roughly $45,000 a month for the same five people hired locally. That's close to 75 percent of the budget back, and most clients put it straight into a bigger platform or a longer runway rather than a smaller bill.
A data talent pool with real depth
India has between 4.3 and 5.8 million software developers, and data engineering sits inside a services industry that has run enterprise data warehousing, BI, and reporting projects for two decades, well before "data engineer" was even a job title anyone used. The pool grows about 11.2 percent a year, roughly double the US rate, refilled by around 2.5 million STEM graduates annually, second only to China. Practically, that means a data engineering role that sits open for months in a US or UK job market, because the skill mix is narrow and the applicant pool is thin, gets a real shortlist here in days.
Quality proven at Fortune 500 scale
174 of the Fortune Global 500 run 390-plus engineering centers in India, employing more than 950,000 people. Walmart Global Tech runs pricing and supply-chain data engineering out of Bengaluru and Chennai, the kind of work that means a stockout prediction is only as good as the pipeline feeding it. JPMorgan Chase employs around 55,000 people here, its biggest technology hub outside the US, running data infrastructure under regulatory reporting requirements that leave zero room for a pipeline silently dropping rows. India also holds the world's highest concentration of CMMI Level 5 and ISO 27001 certified firms. The rate you pay reflects cost of living here, not a lower bar for the pipelines your finance team depends on.
Time-zone overlap that actually works for pipeline operations
India runs on IST, UTC+5:30. Put a data engineer on an 11 AM to 8 PM IST schedule and a US-East team gets about 2.5 hours of live overlap every morning, enough for a standup or an incident review. UK clients get closer to 4.5 hours. The rest of the day is where data engineering actually benefits from the gap: heavy batch jobs and backfills scheduled for your night run and get monitored during India's working day, so a failed load is often already fixed by the time your team logs back on, a genuine follow-the-sun advantage for a role built around scheduled jobs.
Your pipelines, models, and data stay yours
Every engagement runs on a master service agreement with work-for-hire and IP-assignment clauses, so every pipeline, dbt model, and warehouse schema belongs to you from the moment it's built, backed by an NDA and India's Digital Personal Data Protection Act 2023, which carries penalties up to ₹250 crore for a breach. The Act also includes an outsourcing exemption that reduces compliance friction when the data your pipelines process isn't Indian personal data. You're not licensing access to a contractor's infrastructure. You own it outright.
Need the layer above the pipelines too, models, experimentation, or production ML? See data scientists and ML engineers. Most data platforms end up staffed with a data engineer first and one of those two roles second, once the pipes are actually reliable.
You manage the roadmap, we manage the employment
Your data engineer works inside your team: your Jira board, your Slack, your code review standards, your on-call rotation if you run one. On paper, they stay employed by us. Payroll, statutory benefits, a laptop, and leave are handled on our end, not yours, and you never need to open an entity in India to make any of this legal.
That split is the whole arrangement in one sentence: a full-time data engineer who feels like a direct hire, without the paperwork, cost, or exit risk of actually employing someone in another country. If it stops working, you tell us, and we handle the replacement.

Rates by seniority, and what each level owns
Seniority in data engineering is mostly about how much of the platform someone can own without a lead double-checking every pipeline, and it moves the rate more than any single tool does.
| Level | What they own | From |
|---|---|---|
| Associate | Builds and maintains individual pipelines against a spec, writes dbt models for a defined layer, under review from a lead. Solid on SQL, still learning where a transformation should live. | $1,800/mo |
| Mid-level | Owns a full data domain end to end, ingestion through dbt models to the tables analysts query, with little supervision. Writes its own tests and catches a schema change before it breaks a downstream report. | $2,500/mo |
| Senior | Designs the pipeline architecture and warehouse schema for a whole subject area, not just one pipeline. Makes the ETL-versus-ELT and Spark-versus-SQL calls, and catches a bad pattern in review before it spreads. | $3,200/mo |
| Data engineering lead | Sets platform architecture for the whole data stack: orchestration strategy, warehouse cost and performance budget, data quality standards, and the calls on what runs in the warehouse versus a distributed engine. | $4,500/mo |

The honest answers to the usual worries
If you've hired offshore before, or heard the horror stories, you have questions, and a data platform is not a place to gamble on them. Here are the real ones, answered straight.
"Our finance and reporting data is too sensitive to hand to an offshore pipeline."
The same engineering pool runs data infrastructure for JPMorgan's roughly 55,000-person India technology hub and Walmart's pricing and supply-chain platforms out of Bengaluru, under regulatory reporting standards that don't tolerate a dropped row. Quality tracks the hiring bar and review process, not the country, and less than 8 percent of the data engineering candidates who apply to us pass our screen.
"Communication about a complex data model will be a struggle."
English is the medium of engineering education in India and the default working language of the IT industry, so a schema design review or a pipeline incident postmortem happens in English without anyone treating it as a special accommodation. We screen for clear written and spoken communication directly, because a data engineer who can't explain why a transformation changed a number is not a fit for a remote team.
"The time-zone gap will slow down incident response."
A shifted 11 AM to 8 PM IST schedule gives about 2.5 hours of live overlap with US-East each morning and roughly 4.5 hours with the UK, enough for a standup and a review of overnight pipeline runs. The rest of the gap works in your favor for this specific role: a batch job scheduled for your night runs and gets actively monitored during India's working day, so a failure is often already fixed before you're back online.
"The engineer will churn out from under our platform mid-build."
Attrition at India's top IT firms fell from about 23 percent in FY22-23 to 13 percent in FY25, so the sharpest churn years are behind the industry now. Beyond that, the managed model itself is the insurance: if an engineer leaves, you lose a person for a few weeks, not the role or the pipeline documentation, and we backfill it at no extra cost to you.
"We'll lose control of our pipelines, models, or data."
Every contract uses work-for-hire and IP-assignment clauses that vest all created pipelines, dbt models, and infrastructure code in you from the first commit, backed by an NDA and India's Digital Personal Data Protection Act 2023. Your data engineer is not building anything they, or we, get to keep or reuse on another client's stack.
What clients say about our data engineers
"Our data engineer rebuilt our Airflow pipelines and our data is now fresh, tested, and reliable every morning. The analytics team stopped double-checking numbers before every board meeting."
"The Snowflake migration our engineer led cut our query costs by half and turned minute-long dashboard loads into seconds. He explained every tradeoff before making it, which made the whole thing easy to approve."
"Real-time Kafka pipelines built by our data engineer now power our operational dashboard. We can see what's happening in the business live instead of waiting for tomorrow's batch report."
