Senior Full Stack Engineer (Technical Lead)

About Continuum Health Group

Continuum Health Group is a Singapore healthcare group providing primary care and specialist services, including a clinic that is open 24 hours a day. We are building the technology that connects our patient services, clinic operations, communications, reporting and online shop.

About the role

You will be our in-house engineer and the technical lead for the group. You will work directly with the founder and our clinical and operations teams to turn requirements into working systems.

The role is hands-on. You will build the critical components, select established products where they meet our needs, and lead the external developers and vendors who deliver the rest. Work is prioritised and delivered in stages, each with a clear scope, resources and acceptance criteria.

What you will do

• Own the technology roadmap: assess what exists, decide what to build, buy or integrate, and set milestones and acceptance criteria.

• Build one secure integration layer between our applications and our clinic management systems, covering appointments, queues, payments, messaging and reporting.

• Make the data dependable through synchronisation, error handling and reconciliation, so that no booking or payment is duplicated or fails silently.

• Deliver a large service catalogue, online booking, and patient, partner and staff interfaces with authentication, permissions, delegated access and audit trails.

• Develop or integrate an administrative AI assistant for enquiries, bookings and staff handover, with approved knowledge, controlled actions, testing and monitoring.

• Build reporting from enquiry to attendance and payment, and connect our online shop for orders, payments, stock and fulfilment.

• Run production: deployment, monitoring, backups, recovery, access controls and incident handling.

• Lead our technical suppliers: review their designs and code before release, keep every repository and account under CHG's control, and document systems so that another engineer can operate them.

What you bring

• At least six years of personally building, deploying and maintaining production web applications, including one as the lead or only engineer.

• Strong TypeScript and modern front end skills (React or Next.js), with practical back end, API and SQL experience.

• Integrations you have shipped for transactional workflows: bookings, payments, messaging or orders.

• Working knowledge of cloud infrastructure, automated deployment, monitoring and recovery.

• Sound security practice with sensitive data: authentication, role based access and audit logging.

• Practical judgement on architecture and build versus buy, clear documentation, and ownership of a feature from release through adoption.

An advantage

• Healthcare software, or integrations with Plato, GPConnect or comparable clinical platforms.

• Next.js and Sanity, or similar application and content platforms.

• AI assistants that use external tools, structured actions and human handover.

• WhatsApp Business Platform, cloud telephony, payment gateways or e-commerce platforms.

Your first three months

• Review the existing systems, code, access arrangements and suppliers.

• Validate the capabilities and dependencies of the key integrations.

• Agree a prioritised, costed roadmap with the founder.

• Deliver one integration or operational improvement through to production, with monitoring, documentation and recovery in place.

Why join us

• You will build the technology of a growing healthcare group and work directly with the founder.

• Your systems are used every day by patients, clinicians and clinic teams.

• You see the effect of your work on service, efficiency and business performance within weeks.

How to apply

Please send:

• Your CV, with links to systems you have personally built or maintained.

• For two relevant projects: your contribution, the technologies used and the outcome.

• Your notice period or earliest start date.
