Backend engineers who architect APIs, microservices, and real-time systems that scale under pressure. Trained in AI-accelerated development workflows, they build production infrastructure with the reliability your business demands. Dedicated, full-time, starting at $1,499/mo.
A remote Node.js developer is a backend specialist who builds server-side applications using JavaScript and TypeScript on the Node.js runtime. They design RESTful and GraphQL APIs, architect microservices, manage databases, implement authentication systems, and deploy scalable infrastructure — working full-time from a remote location, embedded in your engineering team.
Every Node.js developer in our pool is vetted across these backend technologies. Deep expertise, not surface-level familiarity.
Not vague "backend support." Concrete infrastructure and API deliverables that keep your product running and scaling.
Architect clean, versioned API endpoints with proper authentication, rate limiting, input validation, and error handling. Your developer designs APIs that are easy to consume, well-documented with OpenAPI specs, and built to handle traffic spikes without degrading performance or dropping requests.
Break monolithic applications into independently deployable services with clear boundaries, message-based communication, and proper service discovery. Your developer handles the hard parts — distributed transactions, eventual consistency, circuit breakers, and graceful degradation when individual services fail.
Implement WebSocket connections, server-sent events, and pub/sub architectures for live features like chat, notifications, dashboards, and collaborative editing. Your developer builds real-time systems that handle thousands of concurrent connections using Socket.io and Redis without memory leaks or connection drops.
Design schemas, write efficient queries, implement indexing strategies, and set up connection pooling for PostgreSQL and MongoDB. Your developer profiles slow queries, implements caching layers with Redis, designs data migration strategies, and ensures your database layer does not become the bottleneck as your data grows.
Build and deploy AWS Lambda functions, API Gateway configurations, and event-driven architectures that scale automatically and cost nothing when idle. Your developer handles cold start optimization, proper error handling in serverless contexts, and integration with SQS, SNS, and EventBridge for complex workflows.
Build authentication and authorization systems using JWT, OAuth 2.0, and session-based patterns. Your developer implements role-based access control, API key management, request signing, and security best practices including input sanitization, CORS configuration, and protection against common attack vectors.
Production backend systems our Node.js developers have shipped for clients across SaaS, fintech, and enterprise.
A project management SaaS needed their monolithic PHP backend replaced with a modern API-first architecture. A Syentrix Node.js developer rebuilt the entire backend using NestJS, PostgreSQL with Prisma, and Redis caching. The new API handled 10x the previous request volume with half the server costs. P95 response times dropped from 800ms to 120ms. Third-party integrations that previously required custom code now used the public API.
A healthcare platform needed HIPAA-compliant real-time messaging between providers and patients. A Syentrix Node.js developer built a WebSocket-based messaging system using Socket.io, Redis pub/sub for horizontal scaling, and MongoDB for message persistence. The system handles 5,000 concurrent connections per instance with message delivery latency under 50ms. End-to-end encryption and audit logging met compliance requirements.
A logistics company running a monolithic Express app was hitting scaling walls during peak shipping seasons. A Syentrix Node.js developer decomposed the monolith into 8 microservices — order processing, inventory, shipping, notifications, billing, auth, reporting, and webhooks — connected via RabbitMQ. Deployment cycles went from bi-weekly to multiple times per day. System reliability improved from 99.2 percent to 99.95 percent uptime.
Fixed monthly rates. No hourly markups. No recruiter fees. Full-time, dedicated Node.js backend talent embedded in your team.

See full pricing details →You need scalable backend infrastructure that handles growing traffic, third-party integrations, and complex business logic without breaking under load.
You have outgrown your monolithic architecture and need a backend specialist who can decompose it into scalable, independently deployable services.
You are building chat, live notifications, collaborative editing, or real-time dashboards and need someone who understands WebSocket architecture at scale.
If your backend is a basic database with REST endpoints and minimal business logic, a full-stack developer or a low-code backend would be more cost-effective.
If your bottleneck is UI components, design systems, or user experience, a React developer is the right hire. Node.js developers are backend specialists by design.
Everything you need to know about hiring a remote Node.js developer through Syentrix.
A Syentrix Node.js developer builds and maintains scalable backend systems including RESTful APIs, GraphQL servers, microservices architectures, real-time messaging systems, and serverless functions. They work with Express or NestJS frameworks, manage databases like PostgreSQL and MongoDB, implement caching with Redis, build WebSocket connections for live features, and deploy to AWS or containerized environments. Every developer in our pool is trained in AI-accelerated development, which means they write, test, and debug backend code significantly faster than traditional developers.
We use a four-stage vetting process built specifically for backend Node.js expertise. Stage one reviews production portfolios examining API architectures and system design decisions. Stage two is a live technical assessment building a working API with authentication, database queries, and proper testing. Stage three tests advanced Node.js concepts including event loop mechanics, stream processing, memory leak diagnosis, and microservice communication patterns. Stage four is a two-week paid trial on supervised projects. Our acceptance rate is 4.1 percent.
It depends on where your technical bottleneck is. A dedicated Node.js developer focuses entirely on backend architecture, giving you deeper expertise in API design, database optimization, caching strategies, and system scalability. A full-stack developer divides attention between frontend and backend. If your backend needs to handle high concurrency, complex data processing, or real-time features, a Node.js specialist delivers better architecture. Many clients pair a Node.js developer with a React specialist for senior-level expertise on both layers.
Yes. Our Node.js developers are proficient across the most common backend ecosystems. They work with SQL and NoSQL databases, ORMs like Prisma and TypeORM, and deploy to AWS, Azure, GCP, and containerized environments. For message queues, they work with RabbitMQ, Redis pub/sub, and AWS SQS. Most developers onboard onto an existing codebase within the first week and start contributing meaningful pull requests by day five. We match based on your specific stack requirements, not just general Node.js knowledge.
In the first 30 days, expect onboarding, architecture audit, bottleneck identification, and the first shipped feature or optimization. By day 60, they should own a significant backend domain and have improved API performance measurably. By day 90, they are a fully integrated team member shipping independently and driving CI/CD improvements. Clients commonly report 40 to 60 percent improvements in API response times, 30 percent reduction in infrastructure costs, and significantly faster feature delivery cycles.
