Hire Senior Node.js Developers Who Build Backends That Scale

Node.js powers some of the world’s highest-traffic systems — LinkedIn, Netflix, Uber, PayPal. Building at that scale demands more than knowing Express.js. It demands engineers who understand the event loop deeply, architect microservices that handle millions of requests, and design APIs that teams of engineers can build on for years.

That’s who we staff. Our Node.js developers have shipped the API gateways, real-time communication platforms, and microservice architectures that enterprise companies and unicorn startups built their businesses on — in your time zone, in English, at 50% of US market rates.

What Our Node.js Developers Build

RESTful & GraphQL APIs

Clean, versioned, documented APIs built for the teams who consume them. Our Node.js engineers design API contracts first, then implement them with Express, Fastify, or NestJS — with authentication, rate limiting, caching, and observability baked in from day one.

Real-Time Systems

WebSocket servers, Server-Sent Events, and real-time notification pipelines using Socket.io or native WebSocket APIs. Our engineers have built live collaboration tools, real-time dashboards, and event-driven communication systems at scale.

Microservices & Event-Driven Architectures

Service decomposition, message-driven communication with Kafka and RabbitMQ, distributed tracing, and API gateway design. Our Node.js engineers know how to break a monolith apart without breaking production.

Backend-for-Frontend (BFF) Layers

The API composition, data aggregation, and response shaping layer that sits between your frontend and your microservices. Our Node.js engineers build BFF layers that make React and mobile front-ends fast and decoupled from backend complexity.

Serverless Node.js

AWS Lambda, Google Cloud Functions, and Vercel Edge Functions — our engineers build serverless Node.js systems that scale to zero and back, handling traffic spikes without pre-provisioned capacity.

Client Success Story: Real-Time Platform for a Y Combinator-Backed Fintech

A Y Combinator-backed fintech startup needed a high-performance real-time API to power their core product at launch — with zero tolerance for downtime during Demo Day and enough architectural headroom to scale from hundreds to hundreds of thousands of users after funding. Our Node.js engineers built the NestJS API layer with WebSocket support for live updates, Redis-backed session management, event-driven job processing via BullMQ, and a PostgreSQL data layer with read replica routing for query performance. The platform launched with zero downtime during the Demo Day traffic spike, maintaining sub-100ms p99 API latency under peak load. The engineering quality became a talking point in the founding team’s Series A pitch — and the startup closed funding within six weeks of Demo Day.

Client Success Story: High-Throughput E-Commerce API Rebuild

A fast-growing e-commerce operator had built its product catalog and checkout APIs on a monolithic Node.js codebase that was buckling under peak traffic. Checkout timeouts during high-traffic sale events were costing the business significant revenue and damaging customer trust. Our Node.js engineers decomposed the monolith into independently deployable microservices — catalog, pricing, inventory, and checkout — with an API gateway layer for routing and rate limiting, and RabbitMQ for event-driven coordination between services. Peak checkout API response times dropped from 4.2 seconds to 180ms. The team survived their next major sales event without a single timeout, and traffic capacity increased 5x on the same infrastructure footprint.

Why Companies Choose Our Node.js Developers

  • Event-loop fluent: They understand Node.js concurrency deeply — no blocking operations, proper async/await usage, and backpressure handling for streaming workloads
  • TypeScript by default: NestJS with full TypeScript, typed middleware chains, and end-to-end type safety for APIs consumed by front-end teams
  • API design craft: They write OpenAPI specs before they write handlers — because the API contract is as important as the implementation
  • 50% cost savings: Fully-burdened rates including salary, benefits, taxes, and HR administration
  • Fast start: Most Node.js engineers begin within 1–2 weeks of your first call

Engagement Models

  • Individual Node.js Engineer — One senior Node.js developer embedded in your existing backend team. Ideal for API development, microservices work, real-time systems, or performance optimization.
  • API Development Pods (2–4 engineers) — Node.js backend engineers paired with DevOps and QA in a coordinated squad. Ideal for teams building new API surfaces, decomposing a Node.js monolith, or launching event-driven architecture.
  • Full Node.js Backend Teams (5–20+ engineers) — Complete backend organizations for high-throughput API platforms, real-time communication systems, and event-driven microservice architectures at scale.
  • Contract-to-Hire Node.js Engineers — Evaluate a Node.js developer in your codebase before committing to a permanent hire. You’ll have a clear read on event-loop discipline and API design instincts within weeks.

How To Vet Node.js Developers

Our Node.js vetting identifies engineers who understand the event loop deeply — not just Express routes. The four-stage process:

  1. Technical screening — Event loop internals (microtask vs. macrotask queues, the specific ways Node.js fails under load), stream backpressure, connection pool exhaustion, and async error propagation. NestJS module architecture, Kafka consumer group patterns, and TypeScript proficiency. Over 90% of applicants do not pass this stage.
  2. Take-home exercise — Build a production-quality NestJS API with input validation, authentication middleware, rate limiting, error handling, database integration, and a Jest test suite. Evaluated on API contract design, error surface clarity, and test coverage.
  3. Live technical interview — Performance debugging with clinic.js and Node.js –prof output, code review on a Node.js codebase with real anti-patterns embedded, and system design for a high-throughput event-driven architecture.
  4. Communication screening — Node.js backend engineers often own the API contract that multiple client teams depend on. We assess the ability to communicate breaking changes, deprecation timelines, and performance constraints clearly.

What to Look for When Hiring Node.js Developers

Senior Node.js engineers understand that Node.js’s power comes from non-blocking I/O — and that it fails in specific, predictable ways when that model is violated.

What strong candidates demonstrate:

  • They discuss the event loop naturally when concurrency comes up — they know why CPU-bound work blocks Node.js’s single thread and when to use worker threads or a separate process
  • They’ve diagnosed real Node.js performance problems: connection pool exhaustion, memory pressure from buffer accumulation, event loop lag from synchronous operations, and GC-induced latency spikes
  • They understand stream backpressure and have implemented it correctly in production — not just read about it
  • They have profiling experience with tools like clinic.js, 0x, or Node.js built-in –prof — meaning they’ve measured real performance issues rather than guessing

Red flags to watch for:

  • Using synchronous file I/O (fs.readFileSync) in request handlers “for simplicity” — a sign they don’t understand the event loop consequences
  • Not knowing what happens to a Node.js process when an uncaught promise rejection occurs — or not having a strategy for handling it
  • No experience designing for horizontal scaling: stateless services, session storage in Redis, and coordination patterns for real-time features across multiple instances
  • Treating Node.js as a framework rather than a runtime — candidates who can name Express routes but can’t explain why process.nextTick runs before Promise.then

Interview questions that reveal real depth:

  • “Walk me through how Node.js’s event loop processes I/O operations, timers, and microtasks. What happens when you mix setImmediate, process.nextTick, and Promise.then in the same callback?”
  • “You notice a Node.js API service has 99th-percentile latency that’s 10x the median. Walk me through how you’d diagnose this — what tools would you use and what would you look for?”
  • “How would you design a real-time collaboration feature (like a shared document editor) in a Node.js microservice architecture where multiple instances run behind a load balancer?”

Frequently Asked Questions

Do your Node.js developers use TypeScript?
Yes — TypeScript is the default for all our Node.js engineers, particularly those using NestJS. They write fully typed modules, DTOs, service layers, and API contracts. For projects using JavaScript-only stacks, they can work within that constraint while introducing TypeScript incrementally.
Can your Node.js developers handle high-concurrency and high-throughput requirements?
Absolutely. Our senior Node.js engineers understand the event loop, worker threads, clustering, and load balancing at depth. They’ve designed systems handling tens of thousands of concurrent connections and millions of API requests per day. We’ll screen specifically for high-concurrency experience if that’s a requirement.
Do your engineers have experience with NestJS specifically?
Yes. NestJS is the most requested Node.js framework in our enterprise engagements. Our engineers are fluent in NestJS modules, guards, interceptors, pipes, and its dependency injection system. For teams using Express or Fastify, we have engineers experienced in those frameworks too.
How quickly can a Node.js developer start?
Most Node.js engineers can begin within 1–2 weeks. For specialized roles — real-time systems architects, high-throughput systems engineers — allow 2–3 weeks. You interview and approve every candidate before any engagement starts.
