Core Responsibilities

Primary Functions

Design, build and maintain responsive front‑end web interfaces using HTML5, CSS3, JavaScript/TypeScript, and modern frameworks such as React, Angular or Vue.
Develop server‑side logic, RESTful APIs or GraphQL endpoints, web services and backend microservices to support web application features.
Architect and optimise relational and NoSQL databases (MySQL, PostgreSQL, MongoDB, etc.), schema design, query tuning, indexing and data modelling for performance.
Integrate front‑end and back‑end seamlessly: ensure UI components consume API services correctly, manage data flows and handle errors or loading states in UI.
Build and deploy full‑stack web applications from conception through release: participate in requirement gathering, design, development, testing, deployment and maintenance.
Write clean, maintainable, scalable and reusable code, following software engineering best practices, design patterns and coding standards.
Conduct unit tests, integration tests and end‑to‑end testing, debug issues, troubleshoot root causes and ensure quality of the web application.
Deploy to production environments and support release management, CI/CD pipelines, version control (Git, GitHub/GitLab), branching strategies and build automation.
Monitor performance of web applications: optimise speed, responsiveness, scalability, handle cross‑browser compatibility, mobile responsiveness and UX consistency.
Ensure web application security: implement authentication/authorization, input validation, protect against XSS/CSRF, data encryption, secure APIs and follow security best practices.
Undergo front‑end optimisation: reduce bundle size, implement lazy loading, code splitting, caching strategies and manage assets for improved load times.
Collaborate with UX/UI designers, product managers, QA engineers and other developers to translate wireframes and stories into tangible features, ensuring alignment with product vision.
Maintain documentation: architecture diagrams, API specifications, deployment guides, technical run‑books and user documentation for features delivered.
Stay current with evolving web technologies, frameworks, tools and industry trends; evaluate new libraries, patterns or platforms for team adoption.
Support and maintain production web applications: handle bug fixes, feature enhancements, performance tuning, logging/monitoring and production incident resolution.
Work across teams in agile environment: participate in sprint planning, backlog refinement, stand‑ups, retrospectives and deliver incremental value.
Manage frontend asset pipelines, server builds, deployment scripts, containerisation (Docker) or orchestration (Kubernetes) where applicable and cloud hosting environments (AWS, Azure).
Mentor junior developers or interns: provide code reviews, pair programming, share best practices and help elevate the technical capabilities of the team.
Evaluate technical debt: identify code smells, refactor components, improve test coverage, reduce maintenance overhead and improve reliability of the stack.
Collaborate with DevOps or infrastructure teams to ensure web application deployment, environment configuration, scalability and monitoring systems are aligned with operational requirements.
Assist with user acceptance testing, bug triage, feature release coordination, deployment rollback planning and stakeholder communication.

Secondary Functions

Support ad‑hoc feature prototypes, proof‑of‑concepts or exploratory technology spikes to evaluate new web capabilities.
Contribute to the organisation’s web product roadmap by providing technical insights, innovation suggestions and improvement ideas.
Collaborate with business units and stakeholders to translate user stories or needs into engineering deliverables.
Participate actively in sprint planning, development reviews, demo sessions and agile ceremonies within the software engineering team.
