Job Description

About the Role
We are looking for a Senior Full Stack Developer with 6+ years of experience in Python, React.js, MongoDB, AWS, and Terraform to design, build, and maintain scalable cloud-native applications. You will own end-to-end feature delivery architecting robust Python backend services and APIs alongside high-performance React frontends — backed by MongoDB data stores and deployed on AWS using Terraform-managed infrastructure. You will collaborate closely with architects, product owners, and cross-functional engineering teams to deliver high-quality, secure, and maintainable full stack solutions in an Agile environment.

Key Responsibilities

Backend — Python

- Design, develop, and maintain scalable Python backend services and RESTful APIs using FastAPI, Flask, or Django — applying clean architecture, SOLID principles, and production-grade best practices.
- Build asynchronous backend services using Python async frameworks for high-throughput, low-latency workloads.
- Implement background task processing using Celery — ensuring reliable, scalable execution of long-running and scheduled jobs.
- Write comprehensive unit and integration tests using Pytest — maintaining high code coverage and regression confidence across all backend deliverables.
- Enforce code quality standards using Black, Flake8, and MyPy — contributing to a clean, well-typed, and consistently formatted Python codebase.

Frontend — React

- Design and develop scalable, high-performance React.js applications using TypeScript and modern hooks — delivering accessible, responsive, and pixel-perfect user interfaces.
- Implement complex state management using Redux Toolkit, React Query, or Context API — ensuring predictable and performant application state across data-intensive frontends.
- Integrate React frontends with Python backend REST APIs and GraphQL services — managing asynchronous data flows, error handling, loading states, and cache strategies.




- Build reusable, well-documented React component libraries aligned to design system standards — using Storybook where applicable.
- Write comprehensive unit, component, and E2E tests using Jest, React Testing Library, and Cypress / Playwright.

MongoDB & Data

- Design and implement MongoDB data models — applying document schema design best practices, embedding vs referencing strategies, and indexing for query performance.
- Build and optimise MongoDB aggregation pipelines for complex data transformation, reporting, and analytics use cases.
- Manage MongoDB Atlas cloud database — configuration, monitoring, scaling, backup, and performance tuning.
- Implement Redis caching strategies — session management, API response caching, and rate limiting for high-traffic application workloads.
- Collaborate with data engineers and architects to design effective data access patterns across MongoDB and relational database stores.

AWS & Terraform

- Design and deploy cloud-native full stack applications on AWS — leveraging EC2, ECS, EKS, Lambda, S3, DocumentDB, SQS, SNS, and API Gateway.
- Provision and manage AWS infrastructure using Terraform — developing reusable, modular Terraform configurations for reproducible, version-controlled cloud resource management.
- Implement AWS security best practices — IAM least-privilege policies, KMS encryption, Secrets Manager, and Cognito authentication — across frontend and backend application layers.
- Build and maintain serverless application components using AWS Lambda and Step Functions — designing event-driven, auto-scaling workloads for appropriate use cases.
- Configure AWS monitoring and observability — CloudWatch dashboards, X-Ray tracing, structured logging, and alerting — to maintain production health and support rapid incident resolution.
- Implement and manage CI/CD pipelines using GitLab CI or GitHub Actions — automating build, test, Terraform plan/apply, and deployment workflows across Dev, Test, and Production environments.
