Hire Node.js developers by skill
To hire a Node.js developer, test how they build an API that handles async I/O, errors and data safely, then interview them on that code. DeveloperHiring sources, tests and ranks candidates for you. You hire directly and pay a flat subscription, not agency fees.
Edit the role, then see the skill matrix, screening questions and a sample coding task in about a minute.

What does a Node.js developer do?
Node.js roles are usually backend work: REST or GraphQL APIs, background workers and integrations with other services. Some teams also want serverless functions. We match the task to that.
Which Node.js skills do we test?
The skill matrix for a Node.js role starts with these six areas. You can change the weights in the role builder.
Event loop
Knowing what blocks the event loop and how to move heavy work off it.
API design
Clear routes, input validation, status codes and versioning in Express, Fastify or NestJS.
Data access
Safe queries, transactions and connection pooling with Postgres or MongoDB.
Error handling
No unhandled rejections, useful logs and graceful shutdown.
Security basics
Secrets out of code, input sanitizing and dependency hygiene.
Testing
Integration tests that hit the API with a real test database.
Which screening questions work for Node.js roles?
Screening questions go out by email right after a candidate enters the pipeline. Answers are scored against the skill matrix, with a written reason. Here are three from the Node.js library.
- Q1 What happens to a Node.js server when one request runs a slow synchronous loop?
- Q2 How do you make sure a payment webhook is processed only once?
- Q3 Describe how you structure a Node.js service so it stays easy to test.
What does the Node.js coding task look like?
Idempotent webhook receiver. Build an endpoint that receives order webhooks, verifies a signature, ignores duplicates and queues the work. Time limit 75 minutes.
- Verify the HMAC signature of the request
- Store event ids so duplicates return 200 without work
- Push the job to an in-memory queue with retries
- Write integration tests for valid, invalid and duplicate events
app.post('/webhooks/orders', async (req, reply) => {
if (!verifySignature(req.rawBody, req.headers['x-signature'])) return reply.code(401).send()
if (await events.seen(req.body.id)) return reply.code(200).send({ duplicate: true })
await queue.push('order.created', req.body)
return reply.code(202).send()
})Running hidden tests

failed rejects_bad_signature, dedupes_by_event_idHow do you tell a junior from a senior Node.js developer?
The test and the AI interview look for different signals at each level. Use these to set the seniority in the role builder.
| Level | What you should see |
|---|---|
| Junior | Builds routes and calls a database with guidance. |
| Mid | Owns a service, handles errors, retries and duplicates without prompting. |
| Senior | Plans throughput, observability and failure modes across several services. |
How much does a Node.js developer cost?
Pay varies a lot by country, city, seniority and company. Public salary surveys show broad yearly ranges like these for mid-level to senior Node.js developers. Treat them as a starting point and check current surveys for your market.
Node.js engineers with strong TypeScript and distributed systems experience usually earn more than those who mostly glue APIs together.
| Region | Typical range |
|---|---|
| United States | about 100,000 to 170,000 USD |
| Western Europe | about 50,000 to 90,000 EUR |
| Latin America and Eastern Europe, remote | about 35,000 to 75,000 USD |
| India | about 12,000 to 40,000 USD |

How does the Node.js shortlist work?
Node.js developers often maintain npm packages or contribute to tooling. Their public issues and pull requests show how they communicate. Every candidate then goes through the same screen, the Node.js task and an AI interview about their own solution. Integrity signals show paste events, similarity and AI code likelihood.
The top five land on your shortlist with a scorecard each. Your team meets them and makes the offer. You keep the hire and pay a flat subscription, from $99 per month billed yearly, not an agency fee.
