Design, develop and maintain full-stack features using Node.js on the backend and React on the frontend

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
