Hire senior data engineers for Danish teams
Senior data engineers build pipelines, warehouses and models that move data from source to use, reliably and on time. Each one is tested on data judgement: spotting a transformation that runs cleanly but produces a wrong number, and working through a schema nobody documented. A senior local hire in Denmark takes 4 months on average.
01
Models write SQL well and business logic badly
AI writes SQL well and understands a business badly, so the output can look right and be wrong. A data engineer's value now sits in the checks they put around the numbers.
02
Silent errors are now the bigger risk
The risk has shifted from failures you can see to failures you can't, and that makes verification the core of the role. Engineers who catch a clean-running transformation producing a bad number are the ones worth hiring.
03
Judgement over throughput in every review
When AI can generate a transformation in seconds, an engineer's judgement matters more than their speed. The assessments test for exactly that: a generated result that runs without error and still gets the number wrong.
How we assess data engineers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For data engineers, these criteria carry the most weight.
- AI output verification
Engineers review a generated transformation that executes cleanly but produces an incorrect number, so we can see whether they trust the run or check the result.
- Debugging
Engineers work through a schema nobody documented, so we can see how they trace an unfamiliar structure back to a reliable answer.
- Judgement by risk and ownership
Across both assessments we look at whether engineers prioritise the checks that matter most, and own the consequences when a number goes out wrong.
Cost against a local hire
Engineers are Miyagami employees who work full-time in your team under a service agreement, so there's no individual contractor risk for you. Invoices are monthly, in DKK if you prefer.
Hiring locally in Denmark
- 4 months on average to hire
- Recruitment, payroll and compliance on you
Hiring with Miyagami
- Three weeks to first commit, contracts and payroll handled
- Wrong fit: we replace at our cost
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 data engineers
How much does it cost to hire a senior data engineer in Denmark?
A senior local hire in Denmark costs about kr 91,400 a month all-in, based on a senior software engineer median salary, statutory employer contributions and an amortised recruitment fee. Through us you pay a fixed monthly fee with employment and compliance included, and the pricing calculator shows the two side by side.
How long does it take to hire a data engineer?
You get a shortlist in five working days and a first commit three weeks later. A local senior hire in Denmark typically takes 4 months.
What do you test a data engineer on?
Every data engineer completes both assessments, weighted towards data judgement: a generated transformation that runs cleanly and produces a wrong number, and a schema nobody documented.
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.
