☑️ B2B contract

We are looking for a Full-stack Engineer to join our client, a Singapore-headquartered health-technology and AI startup focused on longevity and preventative care. The product combines diagnostics, wearable signals, lab data, and AI to coordinate personalised health programmes for individual clients.

You will own features end-to-end across two surfaces: internal tooling used by in-house clinicians to assemble recommendations, and the client-facing app that turns those recommendations into daily actions. AI coding agents are part of the daily workflow, and every engineer is expected to push what these tools can do, not treat them as autocomplete. The tech stack is intentionally not fixed; the bar is engineering judgement and shipping speed.

Requirements

• 4+ years of professional software engineering experience, with at least two products shipped to real users

• Computer Science background, or an equivalent track record that shows the same depth in data structures, systems, and applied software design

• Strong fundamentals across both server and client work, regardless of which language or framework you used most recently

• Daily use of AI coding agents in your workflow, with an honest read on where they currently help and where they fail

• Comfort with strict typing, linting, automated tests, and the rest of a modern production setup

• Reliable availability during Central European morning hours, so meetings line up with Singapore afternoons

• Fluent English for technical discussions and written documentation

Responsibilities

• Build and ship features across the full stack, from schema design through to the final UI details

• Develop the internal dashboards used by medical practitioners to interpret client data and assemble recommendations

• Develop the client-facing application that delivers daily health guidance to end users

• Design and tune the security posture separately for internal practitioner tooling and external consumer surfaces

• Integrate inputs from wearables, lab providers, and the physical clinic environment into one coherent product

• Push the AI tooling stack hard, both as part of the development process and inside product features

• Operate as a product-minded engineer: spot problems early, propose solutions, and drive them through to release
