Build with us
like you'd build in-house.

Hire Node.js developers who join your team, your repo, and your standups — backed by a 95-engineer Node organization that ships Express APIs, NestJS microservices, Socket.IO realtime layers, and AWS Lambda functions for startups and Fortune 500s.

On your team, day 1

Engineers join your Slack, your Linear, your sprint board. They pair with your backend team like senior in-house Node hires — no agency PM in the middle.

Direct git access

They open PRs straight into your repo. You see every route, every middleware, every controller, every Jest test, every npm package they add.

You manage the work

You set technical priorities and architecture. We handle hiring, retention, payroll, benefits, conferences, and laptops.

Engagement Models

Three ways
to hire from us.

Same senior Node.js bench, different commercial structure. Pick the model that matches your scope — switch any time, mix across teams.

Hiring Process

From "we need a Node dev"
to onboarded — in 2 weeks.

4-step process pulled straight from how we work. 4 hours to first profile. 2 weeks to a Node.js developer joining your standup.

01
Day 1-2

Requirement Analysis

We map your APIs, traffic volume, latency budget, integrations, and existing stack to decide whether you need an Express generalist, NestJS architect, or serverless specialist.

02
Day 3-5

Choose a Resource

3-5 Node.js developer profiles in your inbox within 4 hours — matched to your framework, domain, and timezone.

03
Day 6-10

Start an Interview

Interview the shortlist. We support with a live Node.js coding round (REST endpoint + DB), an async/event-loop systems round, and reference checks.

04
Day 11-14

Onboarding

MSA, NDA, repo access, infra credentials, Slack invite. By day 14, your Node developer has shipped their first PR and joined daily standups.

Why Choose WebSenor

10 reasons enterprises pick us
over for Node.js over alternatives.

01

5-step vetting

Resume + Node screen + live coding (build a real Express route + test) + system-design (event loop, queues, scaling) + culture fit. <4% acceptance rate.

02

100% source code authorization

You get complete ownership of clean, well-typed Node.js source code. Standard MSA assigns IP to you on day 1.

03

TypeScript-first engineers

All our Node developers ship in TypeScript by default — strict mode, Zod schemas at the edges, no any-leaks in your codebase.

04

Event-loop fluent

They actually understand the event loop, microtasks, libuv, worker threads, and backpressure on streams — not just async/await syntax.

05

Excellent communication

Clear written PR descriptions, timely updates, and async-first collaboration. They write docs without being asked.

06

Replace any time

Not the right fit? Free replacement in 5 business days. No questions asked.

07

Save up to 60%

Senior Node.js developers at India rates — without agency markup, recruiter fee, or freelancer flake.

08

No middlemen

You talk directly to engineers. No account-manager wall, no PM filtering communication.

09

Monthly contracts

30-day notice. No multi-year lock-in. Scale your Node team up or down as roadmap shifts.

10

Production Node at scale

They've shipped Node services at 50k+ req/s, real-time apps with 200k concurrent sockets, and Lambda fleets handling billions of invocations a month.

Client Voices

What companies say
about hiring from us.

"
★★★★★

The NestJS engineer from WebSenor untangled our Express spaghetti in under three months. Our p99 went from embarrassing to investor-friendly.

CT
CTO, Series-C B2B SaaS
"
★★★★★

We needed a Node dev who actually understands the event loop and backpressure, not just async/await trivia. WebSenor's bench is the real thing.

Engineering Manager, fintech

★★★★★

Our serverless migration paid for itself in 4 months. The Node + Lambda engineer they sent could've cost us 3x in the US.

Frequently Asked Questions

Everything you need
to know before hiring.

Express, NestJS, or Fastify — which do your devs default to?
NestJS for greenfield enterprise APIs (DI, modules, decorators). Express for compatibility with existing apps or lightweight services. Fastify for high-throughput / low-latency endpoints. We match the dev to your stack — not the other way around.
Do your Node devs ship in TypeScript or plain JavaScript?
TypeScript by default in strict mode. We use Zod or io-ts at API boundaries, full inference internally, and never disable strictNullChecks. About 5% of our bench is JS-only for legacy maintenance.
What does the 14-day SLA cover?
Day 1 discovery call to day 14 first PR. Typical: shortlist day 3-5, interviews day 6-10, MSA + repo access day 11-13, first commit by day 14.
Can your Node engineers handle real-time (Socket.IO, WebSockets) at scale?
Yes. We've shipped Socket.IO backends with 200k concurrent connections, Redis adapter sharding, sticky sessions on ALB, and reconnection storms handled gracefully. Ask for our realtime case studies on the call.
What about serverless — Lambda, Cloudflare Workers, Vercel?
All three on our bench. About 30% of our Node engineers ship to Lambda + API Gateway weekly, smaller cohorts for Workers (edge) and Vercel Functions. We staff to your platform.
How do you handle replacement?
5 business days notice. We send 2-3 replacement profiles within 4 hours. No fee, no penalty. Most teams never trigger it.
What about IP, NDAs, and source code?
100% source code authorization standard. MSA assigns IP to you on day 1. NDAs signed before any shortlist.
Do you work in our timezone?
Yes. India team gives 4-6 hours of EU / US East overlap. EU and LATAM teams available for US Pacific overlap. Engineers join your standups live.
