How to hire a data engineer at a startup

Updated September 2026

To hire a data engineer at a startup, start by writing down which decisions or product features are blocked by unreliable data, then look for someone who has built and maintained pipelines end to end in a small team. Assess them on SQL, data modelling and a pipeline design conversation about your own data, and hire them before, not after, your first data scientist.

Why the data engineer usually comes first

Many startups hire a data scientist or analyst first and then discover they spend most of their week cleaning exports and fixing broken dashboards. A data engineer builds the foundations that make analysis possible: reliable ingestion, a well-modelled warehouse and tests that catch problems before the board deck does.

Good reasons to hire one now:

• Different teams report different numbers for the same metric.
• Product features depend on data from several sources that are stitched together by hand.
• Your backend engineers are maintaining scripts and scheduled jobs they did not sign up for.
• You are preparing to build machine learning features and need clean, versioned training data.

Analytics engineer or data engineer?

These roles overlap, so be precise in the job description.

• Analytics engineer: models data inside the warehouse, builds the metrics layer and works closely with the business. Mostly SQL and transformation tools.
• Data engineer: moves data in and out of systems, builds streaming or batch pipelines, handles scale, reliability and cost. More software engineering, often Python or a JVM language, plus orchestration tools.

If your main pain is trustworthy reporting, an analytics engineer may be enough. If data is part of the product, or volume and reliability are real problems, you need a data engineer.

Skills to test

• SQL fluency. Window functions, joins across messy sources, and knowing when a query will be slow.
• Data modelling. Can design tables that analysts understand and that survive schema changes upstream.
• Pipeline reliability. Idempotent jobs, retries, backfills, data quality checks and alerts.
• Software engineering habits. Version control, code review, tests and documentation.
• Cost and privacy awareness. Knows how warehouse costs grow and how to handle personal data responsibly.

An assessment process that reflects the job

• Founder or CTO conversation: the data problems you have today and what success would look like in six months.
• SQL session: a realistic dataset with a few awkward edge cases, worked through live. Watch how they check their own answers.
• Pipeline design discussion: describe two or three of your real sources and ask how they would get that data into a usable model. Look for questions about freshness, ownership and failure modes.
• Stakeholder check: 30 minutes with someone who will use the data, such as a head of sales or product, to see how they translate business questions into data work.

Skip long take-home projects. A focused live session tells you more and respects the candidate's time.

Where to find data engineers

Strong candidates often come from backend engineering, analytics teams at scale-ups, or companies where data is the product. Engineers who have built pipelines for fintech, marketplaces or logistics tend to understand messy real-world data. In outreach, describe your sources, your warehouse and the specific problem you want solved. Data engineers are wary of roles that turn out to be dashboard maintenance.

Where Funded.club fits

Funded.club is a fixed-fee recruiting partner for funded startups and fast-growing teams across North America, Europe and APAC. Founded in 2019, it has helped 500+ startups from Seed to Series D, including Supernova.io, WeTravel and Cobalt Robotics. One dedicated recruiter runs each search end to end, with first screened candidates within 7 days and 33 days average from kick-off to hire.

A worked example: for a data engineer on $130,000, a 20 to 25% contingency fee would be $26,000 to $32,500. Funded.club's fixed fee for a role up to $150,000 is $11,500, agreed upfront. Part is paid as an advance at the start and the balance when the candidate accepts. If you do not receive a shortlist of at least 3 qualified candidates within 30 days, you can claim the advance back in full. See pricing and our guide to flat-fee recruiters for startups.

Frequently asked questions

Should a startup hire a data engineer or a data scientist first?

Usually a data engineer, or an analytics engineer if the need is mainly reporting. Without reliable pipelines and a clean warehouse, a data scientist spends most of their time preparing data rather than analysing it.

What is the difference between a data engineer and an analytics engineer?

An analytics engineer models data inside the warehouse and builds metrics for the business, mostly in SQL. A data engineer builds the pipelines that move data between systems and handles scale, reliability and cost, with more general software engineering.

How do you test a data engineer in an interview?

Use a live SQL session on a realistic dataset and a design discussion about your own data sources. Look for questions about data freshness, ownership and what happens when a job fails.

What does Funded.club charge to hire a data engineer?

A fixed fee by salary band: $7,500 for roles up to $110,000, $11,500 up to $150,000 and $15,900 to $21,900 above $150,000, averaging 6 to 9% of salary.
