Hire a dbt developer
Last updated 18 Oct 2026
A dbt developer, usually called an analytics engineer, builds the tested, documented SQL models in your warehouse that dashboards, analysts and AI tools read from. Hire one when your numbers disagree, SQL logic is copied across reports, or your dbt project has grown into something nobody wants to touch. On carbon.talent you can hire a dbt developer full-time, on contract or fractional, anywhere.
What a dbt developer does
- Structures the project: sources, staging, intermediate and mart layers with clear naming.
- Writes models in SQL (and Jinja macros where they help), with incremental models for large tables.
- Tests: unique and not-null keys, relationships, accepted values, freshness, and custom tests on business rules.
- Documents models and metrics so analysts and AI tools can find and trust them.
- Manages CI (slim CI on changed models), environments and deployment, in dbt Cloud or dbt Core with an orchestrator.
- Keeps warehouse cost down: materialisation choices, incremental strategies, model run times.
When to hire one
- Dashboards disagree on revenue, customers or churn.
- Business logic lives in BI tools and spreadsheets, copied many times.
- A dbt project exists but runs are slow, flaky or untested.
- You're moving off stored procedures or a legacy ETL tool onto dbt.
- You want AI assistants or a semantic layer to answer questions from your warehouse, and need clean, documented models for that.
dbt developer vs data engineer
A data engineer gets data into the warehouse reliably (ingestion, orchestration, platform). A dbt developer turns it into models the business uses. Small teams often need one person who does both; say which you need more of. See hire a data engineer and hire an analytics engineer.
What good looks like
- Grain and definitions first, SQL second.
- Tests where failure would mislead someone, not a test on every column.
- Small, readable models over one giant model.
- Knows when incremental is worth the complexity.
What to probe in interviews (IV17)
- "Walk me through how you'd structure a dbt project for orders, customers and subscriptions." Strong: staging per source, intermediate for joins and business logic, marts by consumer, consistent naming, one place for each definition.
- "A model that used to take two minutes now takes forty. What do you check?" Strong: materialisation, full refresh vs incremental, upstream fan-out, warehouse query profile, clustering or partitioning.
- "Explain an incremental model. What goes wrong with them?" Strong: is_incremental, unique_key and merge strategy, late-arriving data, schema changes, when to full-refresh.
- "How do you stop a model change breaking twenty dashboards?" Strong: CI on changed models and their children, model contracts and versions, exposures, communicating deprecations.
- "Snapshots: when and why?" Strong: tracking history of mutable source records (type 2), with a sensible check or timestamp strategy.
- "How would you set up the dbt semantic layer or metrics?" Strong: defines entities, measures and dimensions once; knows the trade-offs vs defining metrics in the BI tool.
Warning signs
- Every model is a table; nothing incremental on large data.
- No tests, or hundreds of tests nobody looks at.
- Macros for everything, making SQL unreadable.

How hiring works on carbon.talent
Option 1: post a role. Post your role free: permanent, contract or fractional; remote or on-site; the country and your overlap hours. See applicants ranked by fit. Vetted profiles show a vetting report from Carbon's real-world data experience test (scenario-based, not a coding test), a working-style profile and a short video intro. Interview with a guide tailored to the role and the candidate, then agree the rate, draft the contract and sign on the platform. Option 2: test someone you found. Already have a candidate? Test a candidate you found on Carbon before you make an offer. ID checks are available on Team and Scale.
Questions companies ask
- What does a dbt developer do?
- Builds tested, documented SQL models in your warehouse with dbt, so dashboards, analysts and AI tools use one set of definitions.
- Is a dbt developer the same as an analytics engineer?
- Mostly. Analytics engineer is the usual job title; dbt is the most common tool they use.
- How do I hire an analytics engineer with dbt on contract?
- Scope the outcome (for example "core revenue and customer models, tested and documented, replacing the stored procedures"), post a contract role with the term and overlap hours, and interview on a project-structure and incremental-model scenario.
- What interview questions should I ask a dbt developer?
- Ask how they'd structure a project, debug a slow model, use incremental models safely, prevent a change breaking dashboards, and when to use snapshots.
- Where can I hire a dbt developer?
- On data talent platforms like carbon.talent, where you post a dbt or analytics engineering role and review vetted data profiles, as well as general freelance platforms where you screen yourself.
- Do I need a data engineer or a dbt developer first?
- If data isn't reliably landing in the warehouse, a data engineer. If it lands but the numbers disagree, a dbt developer.
