For backends that stay correct under real concurrent load

Hire Node.js Developers

Node's asynchronous model is easy to write and genuinely hard to reason about correctly under real concurrency and failure. These engineers are matched to that specific difficulty, evaluated on the work above, and onboarded inside the process your team already runs.

  • Profiles typically within two business days
  • Replacement Assurance: If an engineer is not the right fit, a replacement from our own team starts within ten business days of your request, at no extra cost
  • You interview before placement if you want to
  • At least four hours a day inside your core working hours. Two hours plus a daily written handover for the US West Coast
  • 14-Day Risk-Free Trial: For your first engineer on a time-and-materials engagement. Up to 14 calendar days or 80 logged working hours, whichever comes first. End within the trial and pay nothing for trial hours. Continue beyond it and those hours are billed at the agreed rate. Unpaid trial work remains ours if you stop

01Published, not promised

The assessment behind every engineer we send.

Vetting claims are cheap. The actual Node assessment is published below: five competencies, each with its task and the signal that separates strong from plausible. Borrow it for your own process if it helps.

What we listen forWhether they understand the event loop or just avoid thinking about it.

The task we set

Here is a route handler that occasionally returns a response before a database write finishes. Find the bug and explain why it only happens sometimes.

What strong sounds like
Traces the issue to an unhandled promise or a missing await, and explains the timing condition precisely rather than vaguely.
What gives us pause
Wraps the code in more try-catch blocks without identifying the actual race condition causing the bug.

02Who you actually meet

The bench, priced by seniority.

Three seniority tiers, priced honestly, and the engineers who fill each one today. Real names and photos take their place as soon as we can share them, and the standard stays exactly the same.

Engineer

Features scoped tightly enough to ship inside your review bar, every time.

The right first hire when your seniors already set the standard.

$2,400–3,100per month

Senior

The hard module nobody else wants to own, taken end to end.

Ownership of a surface, without adding a manager to your headcount.

$3,400–4,300per month

Lead

The workstream's decisions, made daily, so nothing waits on a meeting.

One accountable voice for a pod or initiative that can't afford to drift.

$4,600–5,800per month

03From stated problem to first change

Four steps, each closing on evidence.

Four auditable steps from problem statement to merged change. Every one closes with an artefact, and exiting between steps costs nothing.

  1. Define the backend problem

    We map what the service actually needs to handle under real concurrency and failure. The role brief describes the problem to solve, not a list of Node packages to know.

    A brief your leads sign

  2. Match against your stack

    Matching weighs your persistence layer, your queue and event patterns, and how your reviews actually run. Three engineers who fit beat thirty who list the right frameworks.

    Three fits, not thirty CVs

  3. Assess on the real tasks

    Sit in on the async and API-design exercises yourself; judgement shows there in a way CVs cannot. You see judgement under failure conditions, not a rehearsed answer about scalability.

    Evaluation you can watch

  4. Onboard inside your process

    Access, standards and a first bounded change to a real service. Continuity cover means a resignation lands on our desk first and reaches your roadmap as a planned handover.

04Evidence and proof

Engineers who made the backend hold under real load.

Node.js proof is throughput under peak load and errors that fail usefully. Every record here waits for written client approval before production.

05Three shapes, one standard

Add an engineer, a backend pod, or a practice.

One engineer inside your reviews, a pod that owns the service layer, or the product practice when delivery accountability is the real gap. The map is honest about which fits.

  • One named engineer

    A single Node.js specialist inside your direction and your reviews. The smallest commitment and the most common starting point.

    Team extension

  • A backend pod

    A led pod that takes ownership of a service boundary, from contract to deploy to pager. You set priorities and acceptance while the pod carries delivery.

    Delivery pods

  • The practice, not the person

    Where the real requirement is a delivered product rather than an added engineer, the product practice carries the accountability instead.

06Straight answers

Asked before a Node.js hire is signed.

Ask us directly Or browse every role
What does a Node.js engineer actually do day to day?

Designs and maintains backend services, API contracts and asynchronous workflows, diagnoses performance bottlenecks under real load, and keeps error handling designed rather than accidental. The unglamorous majority of the work is making failure modes predictable.

Do you hire for Express, Fastify or NestJS specifically?

Matched to your actual stack. The evaluation focuses on asynchronous reasoning and API design judgement, which transfers across frameworks, then confirms familiarity with whichever one your codebase runs.

Can we run our own interviews as well?

Yes, layer your rounds on top of ours freely. The published tasks above are yours to reuse, and clients regularly watch our assessment live before running their own.

How fast can a Node.js engineer start?

A shortlist lands within days from a continuously evaluated bench. Real start speed then hinges on how quickly your side can grant repository and environment access.

Who manages the engineer day to day?

Direction stays entirely with your leads. What we hold is the employment overhead: continuity, payroll, replacement risk and the awkward conversations when something changes.

What if the engineer is not the right fit?

Flag it early and plainly. The replacement costs you nothing, and the second match is informed by the specific gap rather than a fresh guess.

Do your Node.js developers work with AI coding tools?

Yes, and we would rather show it than hide it. AI drafts boilerplate, handlers and test scaffolding; the engineer owns concurrency decisions, API contracts and everything that merges. Machine-suggested code never lands in your services unreviewed.

How does pricing work for a hired Node.js engineer?

The tier bands above are the honest frame; the exact figure per engineer arrives with the shortlist. No placement fee, and notice periods are the only exit terms.
