Senior Full Stack Developer

Pay Rate Range: $ 53.03 - 56.81/hr. Senior Full Stack Developer Engineering • Technology & Product Job Description: We are looking for a technically strong Senior Full Stack Developer with 6+ years of hands-on experience building scalable, production-grade web applications. The ideal candidate is equally comfortable designing UI mockups in Figma, building responsive React/Next.js frontends, architecting RESTful APIs in Python or Node.js, and owning the CI/CD pipelines that ship it all. You will work across the full delivery lifecycle — from blank canvas to production.

Key Responsibilities

• UI/UX Design & Frontend Development
• Design and prototype application screens, wireframes, and interaction flows in Figma
• Translate Figma designs into pixel-perfect, responsive React and Next.js components
• Implement robust state management using Redux, Zustand, React Query, or Context API
• Consume and integrate REST APIs, handling loading, error, and edge-case states in the UI
• Ensure cross-browser compatibility, accessibility (WCAG), and mobile responsiveness
• Maintain component libraries and enforce design-system consistency across products
• Backend Development
• Design and build RESTful APIs using Python (FastAPI / Flask / Django) and Node.js (Express / NestJS)
• Model and manage relational and non-relational databases; write optimised queries and migrations
• Implement authentication, authorisation, and security best practices (OAuth 2.0, JWT, RBAC)
• Build reusable services, middleware, and shared libraries consumed across applications
• Perform code reviews and enforce backend coding standards, error handling, and logging
• Greenfield Application Development
• Bootstrap new projects from scratch: repository structure, tooling, linting, testing scaffolds
• Define and document architecture decisions (ADRs) for new applications
• Evaluate and select appropriate frameworks, libraries, and cloud services for each use case
• CI/CD & DevOps
• Set up and maintain CI/CD pipelines (GitHub Actions, Azure DevOps, Jenkins, or equivalent)
• Containerise applications with Docker; manage multi-service environments with Docker Compose
• Deploy and configure cloud infrastructure on AWS, Azure, or GCP (compute, storage, networking)
• Automate UI and API deployment workflows including build, test, lint, security scan, and release gates
• Monitor application health, set up alerting, and respond to production incidents

Required Technical Skills

• Frontend: React.js (Hooks, functional components, performance patterns), Next.js (SSR, SSG, ISR, App Router, API routes), State management — Redux / Redux Toolkit, Zustand, or React Query, TypeScript — strong typing across components, hooks, and API contracts, HTML5, CSS3, Tailwind CSS or CSS Modules; responsive and accessible design, Figma — design, prototyping, component library creation, and design handoff
• Backend: Python — FastAPI, Flask, or Django REST Framework; async patterns, Node.js — Express or NestJS; REST API design and middleware patterns, RESTful API design principles; OpenAPI / Swagger documentation, SQL (PostgreSQL / MySQL) and NoSQL (MongoDB / Redis), Authentication & authorisation: OAuth 2.0, JWT, session management
• DevOps & Tooling: Git (branching strategies: GitFlow, trunk-based), Docker and Docker Compose; basic Kubernetes familiarity is a plus, CI/CD tooling: GitHub Actions, Azure DevOps, Jenkins, or CircleCI, Cloud platforms: AWS (EC2, S3, Lambda, RDS) or Azure or GCP, Testing: Jest, Vitest, React Testing Library (frontend); Pytest, Supertest (backend), Package management via JFrog Artifactory (organisation standard — npm and PyPI are not permitted)

Nice To Have

• Experience with GraphQL or gRPC alongside REST APIs
• Familiarity with micro-frontend or monorepo architectures (Nx, Turborepo)
• Infrastructure-as-code experience (Terraform, Pulumi, or AWS CDK)
• Exposure to observability tooling (Datadog, Grafana, OpenTelemetry)
• Contributions to open-source projects or published npm / PyPI packages

Qualifications

6+ years of professional full stack development experience, Bachelor's degree in computer science, Software Engineering, or equivalent practical experience, Demonstrable portfolio or codebase showing end-to-end ownership (design → deploy), Strong written and verbal communication skills; ability to work across cross-functional teams
