The Full Stack Engineer (AI-Assisted Programming) - Part-Time

The Full Stack Engineer is a pivotal role responsible for the end-to-end design, development, deployment, and maintenance of scalable, high-performance, and secure web applications.  

This role combines application development (AI-assisted programming) with hands-on ownership of cloud infrastructure, ensuring reliable, secure, and scalable systems on Azure. The engineer would be working on PUB’s gen-AI assisted procurement-related web application as part of PUB’s AI initiative.   

Key responsibilities 

User Engagement & Requirements Gathering: 

• Conduct user testing sessions to gather valuable feedback on application functionality and user experience. 

• Actively engage with stakeholders and end-users to gather, refine, and translate product functionality requirements into technical specifications/ testable artifacts. 

AI-Assisted Development & Code Quality: 

• Own end-to-end application delivery (frontend, backend, and cloud), leveraging AI coding assistants to accelerate development while ensuring quality, scalability, and maintainability (DRY, modular design, separation of concerns). 

• Build responsive, accessible, and performant web interfaces, using AI to speed up development while retaining full ownership of architecture and reusability. 

• Design and operate secure, reliable, and observable backend services and APIs, guiding AI for boilerplate and tests while owning API contracts and data models. 

• Review and validate all AI-generated code, identifying hallucinations, logic flaws, and maintainability issues before integration. 

Cloud Architecture & Infrastructure: 

• Own the end-to-end design, implementation, and operation of Azure infrastructure, ensuring solutions are secure, scalable, highly available, and compliant by design. 

• Translate application and security requirements into well-architected Azure reference architectures, balancing performance, cost, and operational complexity.  

• Design and implement secure network topologies, including segmented VNets, subnet strategies, private connectivity patterns (Private Endpoints, VNet Integration) to eliminate public exposure of critical services , and network security enforcement using NSGs  

• Architect and deploy cloud-native application platforms, leveraging services such as:  

• Compute: Azure Kubernetes Service (AKS)  

• Integration: API Management (APIM) 

• Security: Key Vault, Managed Identities, Entra ID integration  

• Edge & Protection: Application Gateway, WAF 

• Storage: Azure Blob Storage, Azure PostgreSQL Flexible Server 

• Implement secure-by-default infrastructure patterns, including secret management and end-to-end encryption (in transit and at rest)  

DevOps: 

• Design, implement, and maintain full-stack CI/CD deployment strategies and pipelines, ensuring automated, compliant, and efficient release processes. 

Testing & Quality Assurance: 

• Establish comprehensive automated test strategies, including unit, integration, and end-to-end testing, ensuring high code coverage. 

• Resolve all identified software defects, bugs to maintain application stability and integrity. 

Security & Compliance: 

• Ensure adherence to IM8 compliance requirements and any other emerging organizational compliance mandates. 

• Implement and maintain comprehensive full-stack security measures, including robust authentication, authorization, API security, and frontend security best practices. 

• Establish regular SAST, SCA, container image, vulnerability scans and other regular security related scans and resolve identified security vulnerabilities according to compliance timeline. 

Qualifications & Experience 

Full Stack Development: 

• Degree or Diploma in Computer Science, Computer or Electronics Engineering, Information Technology, or related disciplines. 

• Experience with Git and modern branching workflows (GitFlow, trunk-based development). 

• Strong proficiency in both frontend and backend development. 

• Strong understanding of software engineering best practices (DRY, single responsibility principle, meaningful abstraction, testability) and the ability to enforce these standards within an AI-augmented development workflow. 

• Strong code review instincts — can catch hallucinations, logic errors, and security issues in AI output 

• Working in an agile release model, engineers must be adaptable and proactive to evolving requirements and user feedback. 

Technologies: 

• Next.js, TypeScript, React.js, UI component libraries (e.g., ShadCN, Tailwind CSS). 

• Experience with relational databases 

Security & Compliance: 

• Experience with IM8 compliance and system commissioning for government projects 

• Strong knowledge of frontend security (CSP, CORS, XSS prevention). 

• Experience with backend security (OAuth, JWT, API rate limiting, encryption). 

• Familiarity with cloud security (IAM, Secrets Management, OWASP Top 10). 

DevOps & Infrastructure: 

• Proven experience setting up and managing Azure infrastructure (refer to Azure services listed in the Cloud Architecture & Infrastructure of Key Responsibilities). 

• Experience with CI/CD pipelines using GitLab CI 

• Experience with containerization and orchestration (Docker, Kubernetes). 

Software Quality & Testing: 

• Experience with unit and integration testing (Jest, Cypress, Playwright, Pact). 

• Backend testing using Postman, Supertest, contract testing. 

Observability & Monitoring: 

• Experience implementing application performance monitoring (APM) tools (Prometheus, OpenTelemetry). 

• Knowledge of logging frameworks (ELK Stack, Loki, Fluentd) to track and debug issues across distributed systems. 

Backend Scalability & API Design: 

• Strong experience in API design principles 

• Knowledge of API rate limiting, caching strategies (Redis, Varnish), and performance optimizations. 

• Familiarity with backend service scalability strategies (horizontal scaling, autoscaling, load balancing). 

Bonus Experience (Added Advantage): 

• Experience with government procurement processes 

• Microsoft Certified: Azure Solutions Architect Expert 

• Microsoft Certified: Azure Security Engineer Associate
