Hire Node.js Developers

Hire Node.js developers from PS3G: backend and API engineers for web and mobile products, with React or Angular front ends.

Email hello@ps3g.com

Hire Node.js developers who understand that an API is a product other software depends on, not a folder of route handlers. PS3G’s Node.js engineers build back ends in Express and NestJS with TypeScript, connect them to databases, queues and third-party services, and pair them with the React or Angular front ends and mobile apps that call them. They join your team as named individuals or as a dedicated backend team, for organizations of every size: a founder whose product needs its first real API, a growing SaaS company whose single Node service has become a bottleneck, or a department in a larger organization building an integration layer between systems.

Hire Node.js Developers - PS3G

Hire Node.js developers who are managed, not just placed

The Node.js engineers you hire through PS3G come from our web application development practice, where we build and run APIs for our own products and our clients. They are PS3G employees who have passed a screen by our senior backend engineers, and they remain supported by a technical lead and an account manager for the whole engagement. We are an engineering firm, not a staffing agency: when a memory leak or a queue backlog appears at two in the morning, the engineer has senior colleagues to call.

Node.js is at its best behind a JavaScript or TypeScript front end, and our engineers are comfortable on both sides of that line, as well as alongside our .NET and Python benches when a system has more than one language in it.

What they can do for you

Node JS developers for hire through PS3G are matched to the kind of work below.

  • REST and GraphQL APIs. Authentication, authorization, validation, pagination, rate limiting, versioning and documentation, built in Express, Fastify or NestJS with TypeScript.
  • Integration services. Connecting payment providers, CRMs, email and SMS services, accounting systems and partner APIs, with retries, idempotency and logging that make failures visible.
  • Real-time features. Chat, notifications, live dashboards and collaborative editing with WebSockets, with a plan for scaling beyond one process.
  • Background processing. Job queues, scheduled tasks, file processing, report generation and webhook handling with BullMQ, RabbitMQ or cloud queues.
  • Full-stack product work. A Node.js API with a React or Next.js front end built by the same engineer, which suits early products and small teams.
  • Service splitting and hardening. Breaking a single Node application into a few services where it helps, adding observability, and fixing the performance problems that come from blocking the event loop.

Seniority levels

A mid-level Node.js developer implements endpoints, data access and integrations to a defined contract, writes tests and follows the service’s conventions. A senior developer designs the API contract and the data model, chooses the framework and the queue, sets up authentication, logging and error handling, and reviews the team’s work. A lead backend engineer owns a system of several services, the deployment and scaling plan, and the conversation with your front-end, mobile and data teams.

How hiring works

  1. Brief. A first conversation on the services you run or plan, the framework and database, the clients that call the API (web, mobile, partners), the hosting, and the reporting line and hours you need.
  2. Vetted profiles in days. A short list of Node.js engineers with the APIs and integrations they have shipped, the frameworks and databases they know well, and their availability.
  3. Interviews. Your team interviews each candidate. A live session adding an endpoint to a real service, including validation and a test, shows more than any questionnaire.
  4. Start. Repository and cloud access, local environment setup, a walkthrough of the service map, and first tickets that touch the data layer and the deployment path early.
  5. Scale monthly. Add a second engineer when the integration list grows, go part-time once the API is stable, or turn an individual into a dedicated backend team, all with notice.

Outline the API you need and we will send Node.js profiles that match.

Vetting: a technical screen by our own engineers

Every Node.js engineer on our bench has been screened by senior PS3G backend engineers on working code. The candidate reviews a service with planted faults (an unhandled promise rejection, a synchronous file read inside a request handler, a query built by string concatenation, a secret in a config file, missing input validation on a public endpoint) and explains the consequence of each and the fix. They are asked how they would design pagination and idempotent writes, how they would handle a third-party API that times out, how they would structure a NestJS module, and how they would find a memory leak in production.

The pitfalls when you hire NodeJS developers are predictable. JavaScript is easy to start with, so the pool contains many people who have written front-end code and a tutorial API but never run a service under load. Common gaps are the event loop and what blocks it, database indexing and transactions, authentication done correctly rather than copied, and operational basics such as structured logging and health checks. Some candidates know one framework’s conventions and cannot explain why. Our screen looks for the reasoning, not the framework.

Individual developers vs a dedicated team vs a fixed-scope project

You can hire backend developers one at a time into your team, engage a dedicated team with its own PS3G lead, or hand us a defined API or service to build as a project.

Option Who manages Fits when Example
Individual Node.js developers Your technical lead You have a service, a process and someone to direct the work, and need more backend hands A senior Node.js engineer joining a SaaS team to build a partner API and webhooks
Dedicated backend team A PS3G lead, against your priorities You own the product roadmap but want the back end delivered as a managed stream of work Two backend developers, a QA engineer and a lead running the API that a React app and two mobile apps depend on
Fixed-scope project PS3G owns delivery The endpoints and integrations are defined and you want a price for the whole thing An integration service connecting an online store, a CRM and an accounting system, delivered with tests and documentation

Individual engineers and dedicated teams are billed monthly under our staff augmentation terms and change size with notice. A fixed-scope project is priced as a whole. After launch, running the API under a defined SLA is a managed service, and an architecture review before you decide which route to take is an advisory engagement. A first conversation, a short assessment and a written proposal come first in every case, and the proposal states monthly cost per role rather than hourly rates.

Frequently asked questions

Can I hire full stack developers who cover Node.js and React together?

Yes. Many of our Node.js engineers are full-stack and have built the React or Next.js front end for the APIs they wrote. The profile will say how strong each side is. For an early product or a small team, one full-stack engineer is efficient; once the back end carries integrations, queues and multiple clients, a dedicated backend engineer paired with a React developer usually works better.

Can I hire Express developers for an existing Express application?

Yes. Express is still the most common framework in the applications we inherit, and our engineers maintain and extend Express services as well as NestJS and Fastify ones. If your Express codebase has grown without structure, a senior engineer can introduce TypeScript, validation, a service layer and tests gradually while feature work continues.

Which databases do your Node.js developers work with?

PostgreSQL, MySQL, SQL Server and MongoDB most often, with Redis for caching and sessions, through Prisma, TypeORM, Knex or Mongoose depending on the project. Data modeling, indexing and transactions are part of our screen, because a Node.js API is only as fast as its queries.

Do your Node.js engineers handle deployment and hosting?

Senior engineers are expected to containerize a service, write the pipeline that tests and deploys it, and set up logging and health checks on Azure, AWS or Google Cloud. For larger platform work, such as Kubernetes or infrastructure as code across many services, we add a DevOps engineer rather than stretching the developer.

Where are your Node.js developers located?

Both locations. Account management sits in Wilmington, Delaware; Node.js engineers are in the US and at our India delivery center. For API work that other teams depend on, we make sure the engineer’s hours overlap the teams calling the API, which for India-based engineers means a shifted day with live stand-ups. The mix is yours to choose.
