Hire senior full-stack engineers for Dutch teams
Senior full-stack engineers own a feature from ticket to production across the browser, the API and the database, without a handover. In our vetting they trace a schema change through an API contract and into UI state, and they have to spot a model suggestion that fixes one layer and quietly breaks another. A senior local hire in the Netherlands takes 4 months on average.
01
AI made breadth cheap
AI tools can now produce a passable frontend and a passable API in an afternoon, so breadth alone no longer sets an engineer apart. The real work sits in the seams between layers: data contracts, caching, auth and migrations.
02
Data contracts are harder to generate than code
AI tools produce plausible output at each layer, and that's the problem: a fix at one layer can quietly break the contract at another. A full-stack engineer who understands those contracts is worth more than one who can ship each layer in isolation.
03
The value is in knowing where things connect
A schema change that ripples into an API response and breaks a UI state sits across all three layers at once. That's what a full-stack engineer is now hired to own.
How we assess full-stack engineers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For full-stack engineers, these criteria carry the most weight.
- AI output verification
The engineer must catch a model suggestion that fixes the API contract while silently introducing a regression in UI state.
- Debugging
Tracing a schema change end to end, through the API layer and into a broken screen, requires systematic diagnosis across the full stack without handover.
- Technical understanding
The engineer needs to reason about why a schema change breaks a UI and articulate the causal chain across all three layers.
Wet DBA compliance
Dutch engagements are DBA-compliant. Miyagami employs the engineers and carries the employer obligations, so the risk of disguised self-employment (schijnzelfstandigheid) doesn't sit with you.

Hiring locally in Netherlands
- 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
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.
How do you test software you didn't design
Standard coverage metrics mislead when you test software you didn't design. This entry explains what engineers should do instead when reviewing AI-generated code.
What is a coding agent
A coding agent is an AI system that writes, edits, runs and debugs code autonomously across multiple steps, without a human directing each action.
Questions about hiring full-stack engineers
How much does it cost to hire a senior full-stack engineer in Netherlands?
A senior local hire in the Netherlands costs about €12,200 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 full-stack engineer?
You get a shortlist in five working days and a first commit three weeks later. A local senior hire in the Netherlands typically takes 4 months.
What do you test a full-stack engineer on?
Every full-stack engineer completes both assessments. They also trace a schema change end to end as it ripples into an API contract and a UI state, including a model suggestion that fixes one layer and quietly breaks another.
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.
