Hire Node.js developers
Senior Node.js developers who build APIs, background services and event-driven systems. Each one is assessed on reasoning about a codebase they didn't write and on catching a confident, wrong migration before it ships.
01
AI generates plausible but broken async code
Copilot and similar tools produce async Node.js patterns that look correct but silently swallow errors or create race conditions. A developer now needs to read generated code more critically than hand-written code.
02
Migration scripts now take minutes to write
An engineer can prompt an agent to draft a database migration or a service-to-service refactor in minutes. The risk shifts from writing speed to verification, so the developer who reviews the output matters more than the one who prompted it.
03
API scaffolding is mostly automated now
Route handlers, middleware chains and OpenAPI schemas are generated quickly with the right prompts and context. Senior Node.js developers spend more time on data contracts, error handling strategy and operational concerns than on boilerplate.
How we assess Node.js developers
Every engineer works through a fundamentals assessment with AI tools switched off and a second assessment with their own agents running. For Node.js developers, these criteria carry the most weight.
- Debugging
In Node.js specifically, we watch how a developer traces an async bug across event loop ticks and identifies whether a race condition lives in application code, middleware or the runtime itself.
- AI output verification
We give the developer a plausible but incorrect migration generated by an AI tool and watch whether they catch the flaw, explain why it's wrong, and correct it before treating it as production-ready.
- Technical understanding
We ask the developer to reason about a Node.js service they haven't seen before, tracing how requests flow, where latency is likely to sit, and what would break first under load.

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 Node.js developers
How senior are the Node.js developers you place?
The Node.js developers we put forward have 6+ years' experience on average, and they've shipped and maintained production systems in Node.js. Every one has passed both assessments, and you see both scorecards before you meet them.
How do you test Node.js specifically?
Both assessments use a real Node.js codebase. In the first assessment, no AI tools are allowed, so we see how a developer reads unfamiliar code and debugs async issues. In the second, they use their own agents, and we watch what they verify before trusting the output.
How quickly can a Node.js developer start?
You get a shortlist within five working days of agreeing a brief, and shortlist to first commit typically takes three weeks. There's no recruitment fee and nothing to pay upfront.
What does a Node.js 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 repositories?
Yes. They join your existing stack, use your version control, your CI pipeline and your communication tools. We don't require a separate environment or any tooling changes on your side.
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.
