Job description

We’re hiring a Senior Full Stack Developer to lead development in a team. You’ll own features end to end across the frontend and backend, work directly with the client’s stakeholders, and help shape technical direction from the start. This role suits someone who is strong hands‑on with Node.js, React, and TypeScript, communicates clearly with clients, and is comfortable guiding other engineers.

Key Responsibilities

• Lead the design, development, and delivery of production web applications using Node.js, React, Next.js, and TypeScript.
• Act as a primary technical point of contact for the client: join requirement discussions, explain trade-offs, give estimates, and report progress.
• Make and document architecture decisions across APIs, data models, and frontend structure, including microservices, queues, caching, background jobs, and micro-frontends where they fit.
• Design, build, and consume REST and GraphQL APIs, including Apollo Server/Client.
• Design schemas and optimize queries across PostgreSQL/MySQL and MongoDB/Redis.
• Implement secure authentication and authorization (JWT, OAuth 2.0, sessions) and follow API security best practices.
• Turn Figma designs into accessible, responsive interfaces and build reusable components and design systems in Storybook.
• Set and maintain quality standards through code reviews, unit, integration, and component tests, and end-to-end testing where needed.
• Improve frontend performance (Core Web Vitals, code splitting, lazy loading) as well as API and database performance, while meeting WCAG standards.
• Mentor team members, share best practices, and help the team use AI-assisted tools (Cursor, Claude, and similar) effectively.
• Get up to speed quickly on unfamiliar client codebases and adapt to their conventions.

Requirements

• Bachelor’s degree in computer science, Software Engineering, or a related field.
• 5+ years of professional full stack development experience on production web applications.
• Strong proficiency in TypeScript and modern JavaScript (ES6+) on both client and server.
• Strong experience with Node.js and at least one backend framework (Express, NestJS, or Fastify), and with React and Next.js on the frontend.
• Experience designing, building, and consuming REST and GraphQL APIs, including Apollo tooling.
• Solid database experience with PostgreSQL/MySQL and MongoDB/Redis, including schema design and query optimization.
• Good understanding of authentication, authorization, and core API security practices.
• Familiarity with backend architecture patterns (microservices, message queues, caching, background jobs) and micro-frontend architecture (e.g., Module Federation).
• Solid skills in HTML5, CSS3, responsive design, and CSS-in-JS or Tailwind CSS.
• Experience with state management and data fetching (Redux Toolkit, Context API, React Query).
• Ability to write tests with Jest, React Testing Library, and Supertest; Playwright or Cypress experience is a plus.
• Experience building reusable components and design systems (e.g., Storybook) from Figma designs.
• Knowledge of web performance optimization and accessibility standards (WCAG).
• Familiarity with Git, CI/CD pipelines, Vite/Webpack, and Docker; exposure to AWS, Azure, or GCP is a plus.
• Hands‑on experience with AI-assisted software development (Cursor, Claude, or similar).
• Previous client-facing experience, with strong written and verbal communication skills in English.
• Proven leadership ability: mentoring developers, leading technical discussions, and taking ownership of delivery.

Nice to Have

• Experience with Python (FastAPI, Django, or Flask) for backend services or scripting.
• Hands‑on experience integrating AI/ML or LLMs, such as features built on LLM APIs, RAG pipelines, or AI-powered workflows.
