Hire senior systems engineers
Senior systems engineers build the software other code depends on: performance-critical services, concurrency, networking and Linux-level work in Rust, C++, C and Go. Each one is tested on races, memory and latency, first with AI tools off and then with their own agents on.
01
Plausible code hides the real bugs
Models produce systems code that compiles and passes its tests while hiding a data race, a leak or undefined behaviour. Those bugs surface under load in production, so engineers have to read generated code for concurrency and memory safety as well as correctness.
02
Performance claims need a profiler
An agent will happily say a change is faster. A systems engineer proves it with a benchmark and a profile, and catches the regression in tail latency that an average hides.
03
The blast radius is larger
Systems code sits underneath everything else: a message broker, a storage layer, a device driver. A mistake affects every service above it, so deciding what an agent may touch, and what needs a human review, is part of the job.
How we assess systems engineers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For systems engineers, these criteria carry the most weight.
- AI output verification
Engineers review a generated change to concurrent code that passes its tests but races under load, and the scorecard shows whether they find what the tool got wrong before it merges.
- Debugging
Engineers track down a memory or latency regression that only shows up with a profiler or under load, which tests whether they measure before they guess.
- Judgement by risk and ownership
Across both assessments, reviewers watch how engineers weigh safety against speed in low-level code, and whether they own the call on what ships and what needs a second review.

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.
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.
What changed about code review
AI-generated code has changed what code review looks for. This entry explains why reviews take longer and what skills reviewers now need.
Questions about hiring systems engineers
How much does it cost to hire a senior systems engineer?
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 systems 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 systems engineer on?
Engineers complete both assessments plus a systems review: a generated change to concurrent code that passes its tests but races under load, and a memory or latency regression that only shows up with a profiler.
Systems engineers by market: Netherlands, United Kingdom, Germany, Sweden, Belgium, Ireland, France, Denmark, Switzerland, United States, Canada
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.
