Hire PostgreSQL developers
Senior PostgreSQL developers who treat the database as the source of truth for your product. They design schemas that hold invariants, write migrations you can roll back safely, and can tell when a query plan is misleading you.
01
AI writes migrations; engineers review them
AI tools now generate ALTER TABLE scripts and index suggestions faster than any DBA could type. The engineers who use them well are the ones who read the execution plan before running anything in production.
02
Vector search arrived inside Postgres
pgvector turned Postgres into a first-class store for embeddings, so engineers now design schemas that serve both relational queries and semantic search from a single database. That requires understanding approximate nearest-neighbour indexing alongside B-tree fundamentals.
03
Generated SQL is harder to audit
ORMs and AI tools produce queries that work on small datasets and fall apart under load, and the gap between 'it ran' and 'it ran correctly' is wider than ever. PostgreSQL engineers need to catch that gap before it reaches a user.
How we assess PostgreSQL developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For PostgreSQL developers, these criteria carry the most weight.
- Debugging
In the first assessment, engineers are given a slow query on a real schema and must use EXPLAIN ANALYSE to find whether the planner chose the wrong index, a sequential scan, or a statistics mismatch.
- AI output verification
In the second assessment, engineers run an AI-generated migration against a populated test database and must confirm it's safe to apply without a full table lock before they're allowed to proceed.
- Judgement by risk
Engineers are asked to choose between two schema designs for a high-write table and must defend the trade-off between normalisation, lock contention, and future query patterns.

What is Supabase?
Supabase is an open-source backend-as-a-service built on PostgreSQL, offering auth, storage, APIs, and real-time data without vendor lock-in.
What is Backend as a Service (BaaS)?
BaaS provides pre-built cloud infrastructure (databases, auth, storage, APIs) so teams ship apps without building or managing servers from scratch.
How to review AI-generated code
Reviewing AI-generated code changes some of what reviewers look for and keeps the rest. This entry covers both, plus the specific failure modes to check for.
Questions about hiring PostgreSQL developers
How senior are the PostgreSQL developers on your books?
The PostgreSQL developers we put forward have 6+ years' experience on average, and they've shipped and maintained production systems in PostgreSQL. Every one has passed both assessments, and you see their scorecards before you meet them.
How do you test PostgreSQL skill specifically?
The first assessment gives them a real codebase with a slow query and a broken migration. They must use EXPLAIN ANALYSE, identify the problem, and propose a fix without AI tools. The second assessment tests whether they can verify AI-generated SQL before trusting it.
How quickly can a PostgreSQL developer start?
You get a shortlist within five working days of agreeing on the role. From shortlist to first commit typically takes three weeks, covering your interviews and onboarding access.
What does a PostgreSQL developer cost?
You pay a fixed monthly fee of €5,600 to €8,000 per full-time engineer, with employment, payroll and compliance included and no recruitment fee. The pricing page compares it with the all-in cost of a senior local hire in your country. Engagements are full-time with a three-month minimum, and if a placement doesn't work out, we replace them at our cost.
Do they work in our tools and codebase or their own setup?
A full-time PostgreSQL developer costs €5,600 to €8,000 a month, with no recruitment fee and nothing upfront. Engagements are full-time with a three-month minimum. If the fit's wrong, we replace them at our cost.
Get a shortlist within five working days
You share the roles and the stack in a short form or a thirty-minute call. Within five working days you get named senior engineers to review, each with both scorecards.
