Lead II - Software Engineering

Full Stack Developer (React & Python/Node.js - AWS) Job Summary We are seeking a Full Stack Developer to design, build, and maintain secure, high-performance web applications. In this role, you will work on everything from responsive user interfaces to scalable backend services. You will build user-facing features using React and power them with backend microservices using Python or Node.js. Because our application handles critical systems, you will place a massive focus on secure API development and follow DevOps best practices to deploy code safely and efficiently to AWS.

Responsibilities

• Frontend Development: Build modular, responsive, and highly interactive user interfaces using React JS, Redux/Context API, and modern CSS frameworks.
• Backend Development: Design and scale robust backend services and microservices using either Python (FastAPI, Django, Flask) or Node.js (Express, NestJS).
• Secure API Development: Architect and secure RESTful or GraphQL APIs, ensuring strict protection against vulnerabilities like injection and broken object-level authorization.
• Cloud Infrastructure: Deploy and manage application components natively within AWS using containerized environments.
• DevOps Integration: Own and manage deployment workflows by writing Infrastructure as Code (IaC) and building automated CI/CD validation gates.
• Data Management: Write optimized queries and design schemas for both relational databases (PostgreSQL, MySQL) and NoSQL stores (DynamoDB, MongoDB).

Required Technical Skills

• Frontend: React JS, JavaScript (ES6+), TypeScript, HTML5, CSS3, Webpack/Vite
• Backend: Python (FastAPI/Django) OR Node.js (Express/NestJS)
• AWS Cloud: EC2, S3, Lambda, ECS/EKS, API Gateway, CloudWatch, RDS
• Security: OAuth 2.0, OIDC, JWT, IAM policies, CORS configuration, encryption (HTTPS, KMS)
• DevOps: Docker, Git, GitHub Actions/GitLab CI, Terraform or AWS CloudFormation
• Databases: PostgreSQL or MySQL, and DynamoDB or MongoDB

Required Security Practices (Crucial Focus)

• Secure API Design: Implementing rigorous input validation, output encoding, and strict rate-limiting to prevent Denial of Service (DoS) attacks.
• Authentication & Authorization: Enforcing secure identity management with token-based authentication and Role-Based Access Control (RBAC).
• Secrets Management: Preventing hardcoded credentials by using secure storage tools like AWS Secrets Manager or Systems Manager Parameter Store.
• Security Scanning: Utilizing automated tools within the CI/CD pipeline to scan code for vulnerabilities and dependency flaws before deployment.

Experience and Qualifications

• Years of Experience: 8-10 yrs years of professional full-stack software development experience in a production environment.
• Architecture Understanding: Strong grasp of serverless architectures, event-driven systems, and microservices patterns.
• Testing Rigor: Experience writing comprehensive unit, integration, and end-to-end tests for both frontend and backend systems.
