Hire senior Node.js developers who build fast, typed backends

Senior Node.js engineers who build typed APIs, real-time services and serverless backends in TypeScript, inside your repos and on your schedule.

By the Ryz Labs team · Updated October 2026

Hiring Node.js developers through Ryz gets you senior Latin American engineers who build backend services in TypeScript that hold up under real traffic. They are top 1% of the candidates we interview, they embed in your product team, and they work within an hour of US time zones.

What our Node.js developers work on

Node.js is often the backend for product teams that move quickly and share TypeScript across the stack. Our developers work with NestJS, Fastify and Express, Prisma or Drizzle on Postgres, Redis, and AWS or Vercel. Typical projects:

REST and GraphQL APIs in TypeScript with NestJS, Fastify or Apollo Server, with schema validation through Zod.
Real-time features: WebSockets, Socket.IO, server-sent events for streaming LLM responses and presence systems.
Serverless backends on AWS Lambda with API Gateway, SQS, EventBridge and DynamoDB.
Background job systems with BullMQ and Redis for email, billing and data sync.
Backend-for-frontend layers for Next.js and React Native apps, including auth with OAuth and session management.
Third-party integrations with payment, messaging and CRM APIs, with webhooks handled safely.

Skills we vet for

The event loop. Microtasks versus macrotasks, what blocks the loop and how to keep CPU-heavy work off it with worker threads.
TypeScript depth. Strict mode, generics, discriminated unions and types that catch bugs instead of adding noise.
Framework design. NestJS modules and dependency injection, Fastify plugins and hooks, middleware ordering in Express.
Data access. Prisma or Drizzle with Postgres, transactions, connection pooling in serverless and avoiding N+1 queries.
Streams and backpressure. Node streams, pipelines and handling large uploads or exports without exhausting memory.
Testing. Vitest or Jest, Supertest for HTTP, and integration tests against real databases in containers.
Security. Input validation, dependency auditing, JWT pitfalls, rate limiting and safe webhook verification.
Observability. Structured logging with Pino, OpenTelemetry tracing and reading heap snapshots.

How we vet Node.js developers

Our recruiters source Node.js engineers who have run backends in production, not only built frontends with a thin API. Our in-house ARC system ranks the pipeline, and candidates complete structured NTRVSTA AI interviews on Node internals, API design and debugging. Recruiters review every candidate before and after, then send you a curated shortlist. AI scores are advisory. People decide.

Sample interview topics

An API's p99 latency spikes every few minutes while CPU looks normal on average. How do you check for event loop blocking, and what tools do you use?
Memory grows steadily in a long-running Node service. Walk through capturing and comparing heap snapshots to find the leak.
Design a webhook receiver for a payment provider that handles retries, duplicates and out-of-order events.
Your Lambda functions exhaust Postgres connections at peak. What are your options, from RDS Proxy to changing the data access pattern?
How would you stream an LLM response from a model API to a browser, and handle client disconnects and timeouts?

Ways to hire Node.js developers

Option	Best for	Trade-offs
Freelance marketplace	Quick APIs, prototypes and small integrations	Many JavaScript profiles are frontend-first. Backend depth and availability are hard to verify.
Staffing or recruiting agency	Volume hiring across JavaScript roles	Screens often blur front-end and back-end skills.
In-house recruiting	Core platform owners	Competitive market for senior TypeScript backend engineers, with long cycles.
Ryz Labs staff augmentation	Adding senior Node.js engineers to your product team	You set direction and standards. Best with a defined roadmap.
Ryz Labs dedicated team	A new product or platform built by one coordinated team	A dedicated group with a tech lead, planned and scoped up front.

Ryz is not the right fit if you want to start with a self-serve trial or hourly gigs, or if you need published pricing before any conversation. Teams that need engineers in Asian or European hours should look at global networks.

Why hire Node.js developers from Latin America

Node.js teams tend to ship often, with small pull requests and quick reviews. That rhythm only works when reviewers and authors are online together. Our developers work within an hour of US time zones, so a pull request opened after lunch can be reviewed, revised and merged the same afternoon.

The region has a large, active TypeScript community, and many senior Node.js engineers have built backends for US startups and enterprises alike. They are used to working closely with frontend and mobile teammates, in English, inside your usual tools.

FAQ

Do your Node.js developers write TypeScript?

Yes. Nearly all of our Node.js work is in strict TypeScript. We can also staff developers who maintain older JavaScript codebases and migrate them gradually.

Can they work across the stack?

Many can. If your team shares code between a Next.js frontend and a Node backend, we can match engineers with strong backend skills and solid React experience.

Which industries do your Node.js developers work in?

We place engineers with companies across industries, including financial services, ecommerce, media, healthcare and SaaS. For regulated work, they build inside your cloud accounts under your access controls, and they follow your security review process from the first pull request.

How is pricing set?

We provide a custom quote, scoped per team. You get a plan, a price and the names of the people who would do the work before you sign.

What is the contracting model, and what hours do they work?

You sign one contract with Ryz. Our engineers work with us as independent contractors, and we handle paying them. They work within an hour of US time zones.
