Senior Full-Stack Developer (React.js+Node.js)

Company Introduction

Codebase builds exceptional software teams for clients across the USA and India. We take on our clients' biggest engineering risks — speed, quality, and the cost of hiring the wrong people — and solve them with vetted engineering talent and a custom agile process. Codebase is a great place to work at. The culture is transparent and every employee, irrespective of their position, is given a chance to be heard.

You'll own features end-to-end — from UI components to backend APIs — working closely with designers, PMs, and fellow engineers to ship scalable, production-grade software. If you care about clean code, fast feedback loops, and building things that last, this is for you.

Key Responsibilities

• Design, develop, and maintain scalable full stack features across React.js frontends and Node.js backends
• Build and consume RESTful APIs; contribute to microservices architecture decisions and backend service design
• Write clean, well-structured TypeScript with a focus on performance, readability, and long-term maintainability
• Collaborate with designers and product managers to translate requirements into production-ready implementations
• Manage data models and queries across relational and NoSQL databases (PostgreSQL, MySQL, MongoDB)
• Own your code through the full lifecycle — design, build, test, deploy, and monitor in production
• Set up and maintain CI/CD pipelines; deploy and manage services on AWS (ECS, Lambda)
• Conduct and participate in code reviews to maintain engineering standards across the team
• Troubleshoot and resolve performance bottlenecks, bugs, and production issues proactively
• Contribute to technical documentation, architecture discussions, and sprint planning

Requirements

• 6+ years of hands-on full stack experience with React.js and Node.js in production environments
• Strong command of TypeScript, ES6+ features, and async/await patterns
• Proficiency with Express.js, Nest.js, or a comparable Node.js framework
• Solid understanding of REST API design, microservices architecture, and database modelling (MongoDB, PostgreSQL, or MySQL)
• Hands-on experience with Git, CI/CD pipelines, and cloud platforms — particularly AWS (ECS and Lambda)
• Experience with state management solutions such as Redux, Context API, or Zustand
• Ability to write clean, well-tested code and participate meaningfully in code reviews

Nice to have

• Docker and Kubernetes for containerisation and orchestration
• WebSockets or real-time communication patterns
• Testing frameworks — Jest, Mocha, or similar
• Serverless architecture and function-based compute models

Soft Skills

• Excellent problem-solving and analytical skills.
• Strong communication and interpersonal abilities.
• Ability to work independently and as part of a team.
• Proactive and eager to learn new technologies.
