Responsibilities

• Conduct user testing sessions to gather feedback on functionality and user experience.
• Engage with stakeholders to translate requirements into technical specifications and testable artifacts.
• Own end-to-end delivery (frontend, backend, and cloud), leveraging AI coding assists while ensuring quality and maintainability.
• Build responsive, accessible web interfaces with ownership of architecture and reusability.
• Design and operate secure, reliable backend services and APIs; manage API contracts and data models.
• Review AI-generated code to identify hallucinations and security issues before integration.
• Design, implement, and operate Azure infrastructure for secure, scalable, highly available solutions.
• Translate requirements into well-architected Azure references, balancing performance, cost, and complexity.
• Establish CI/CD pipelines and automated testing strategies with secure-by-default practices.
• Implement comprehensive security measures, including authentication, authorization, and API security.

Job description

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-assistedprogramming)with hands-on ownership of cloud infrastructure, ensuring reliable, secure, andscalablesystems on Azure.Theengineer would be workingon PUB’sgen-AIassistedprocurement-related web applicationas 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),leveragingAI 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 whileretainingfull ownership of architecture and reusability.

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

• Review andvalidateall AI-generated code,identifyinghallucinations, 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, includingsegmentedVNets, subnet strategies,private connectivity patterns (Private Endpoints,VNetIntegration) toeliminatepublic exposure of criticalservices,and network security enforcement using NSGs

• Architect and deploy cloud-native application platforms,leveragingservices 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, includingsecret management and end-to-end encryption (in transit and at rest)

DevOps:

• Design, implement, andmaintainfull-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, bugstomaintainapplication stability and integrity.

Security & Compliance:

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

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

• Establish regularSAST, SCA, container image, vulnerability scans and otherregular security related scans and resolve identified security vulnerabilitiesaccording to compliance timeline.
