• Design and manage data models and queries across MySQL and MongoDB, choosing the right store for each use case.
• Build and maintain well‑structured, documented and versioned APIs (REST or GraphQL) consumed by web and mobile clients.
• Leverage AI‑assisted development tools (such as GitHub Copilot, Claude Code, Cursor or similar) as a core part of the daily workflow, from code generation and refactoring to test writing and documentation.
• Apply sound judgment over AI‑generated code: review, validate and take full ownership of everything shipped to production.
• Contribute to architecture decisions, technical design reviews and the long‑term health of the codebase.
• Write automated tests (unit, integration, end‑to‑end) and maintain high standards of code quality through code reviews and CI/CD pipelines.
• Deploy, monitor and troubleshoot services in cloud environments (AWS/Azure/GCP), including containerised workloads.
• Ensure secure coding practices throughout, including authentication, authorisation, data encryption and protection of personal and health data in line with relevant regulations, in collaboration with the Cybersecurity & IT team.
• Optimise application performance, reliability and scalability as the user base grows.
• Integrate third‑party services, devices and data sources (such as payments, wearables and messaging) as required by the product roadmap.
• Collaborate closely with the Product Manager and Designer from discovery through delivery, providing effort estimates and technical input on feasibility.
• Support production operations, including participation in incident response and on‑call arrangements where needed.
• Mentor junior engineers and contribute to engineering standards, documentation and best practices as the team grows.
• Stay current with emerging technologies, frameworks and AI coding workflows, and bring practical improvements to the team.

• Strong hands‑on experience with Node.js (Express, NestJS or similar) and modern JavaScript/TypeScript.
• Strong hands‑on experience with React and modern frontend development practices.
• Solid experience with both relational and NoSQL databases, ideally MySQL and MongoDB, including schema design and query optimisation.
• Demonstrated fluency with AI‑assisted coding tools and workflows in daily development, with the judgment to review and own AI‑generated code.
• Experience designing and consuming APIs (REST or GraphQL).
• Experience with cloud platforms (AWS, Azure or GCP), Docker and CI/CD pipelines.
• Good understanding of software security fundamentals; familiarity with healthcare data privacy requirements (PDPA or equivalent) is an advantage.
• Experience with automated testing and maintaining quality in a fast‑moving codebase.
• Experience in healthtech, digital health or another regulated space is an advantage.
• Bachelor’s degree in Computer Science, Engineering or a related field, or equivalent practical experience.
