- Work Across the Stack: Collaborate with fellow developers to build, test, and ship high-quality features, while maintaining robust documentation and clear modularity.

- Test, Validate, and Refine: Write unit and integration tests, participate in code reviews, and debug issues across environments.
- Co-Creating Requirements: Collaborate with product managers, designers, and other developers to refine designs, iterate quickly, and respond to evolving user needs.

**[What we are looking for]**
- Highly familiar with frontend and backend languages, including JavaScript, Python, HTML and associated UI libraries (e.g. Angular Material, Prime)
- Proficiency in frontend frameworks (e.g. Angular, Node.js), backend frameworks (e.g. Fast API, Django), and building an event-driven, web-services based architecture. Highly familiar with enterprise data flows (e.g., ESB, API GW, MQ, AWS Kafka).
- Experience in configuring and deploying to cloud platforms, including setting up instances, storage, and connectivity. Cloud certification (e.g. AWS Certified Associate and up) and experience working on Government Commercial Cloud is an advantage.
- A strong command of Git workflows, as well as automated testing (e.g. Selenium, Playwright, or equivalent), is essential to succeed in the role.
- Know-how to integrate AI tools (e.g. Copilot, Cursor) to accelerate development while ensuring compliance with organisational governance and controls.
- Strong communication and collaboration skills, you proactively seek feedback, handle ambiguity, and get things done.
- Comfortable in a startup-like setting, where roles flex and speed matters, and bring a proactive attitude and strong ownership mentality to the table.
