The Full Stack Engineer (AI-Assisted programming)

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
