Description
Backend Developer — Tree3 Health
About Tree3 Health
Tree3 Health is a Hong Kong-based digital health platform founded in 2021.
We partner with major insurers including Prudential Hong Kong, and we're building the next generation of accessible, technology-enabled primary care.
Our platform combines a distributed practitioner network, mobile-first patient experience, and integrated medication fulfillment into a single seamless workflow.
About the Role
This is a full-time, fully Backend Developer role for candidates.
No relocation required — you'll work from wherever you're most productive, with full timezone alignment to our Hong Kong team (both UTC+8).
You'll design, develop, and maintain the scalable backend services and APIs that power our mobile platform, working primarily within a modern Django + DRF codebase.
We are an AI-native engineering team.
We heavily leverage AI-powered coding tools (Claude Code, Cursor, Copilot) for both feature development and platform maintenance, and we expect you to actively use, manage, and adapt to these workflows — not as a side experiment, but as the default way we ship.
We're hiring based on capability, not years of experience.
A developer who genuinely ships fast with AI tooling will outperform a more senior engineer who doesn't — and we want to talk to either.
Day-to-day, you'll collaborate directly with the founder, product, mobile, and front-end teams to refine requirements, deliver features, and resolve issues.
You'll participate in AI-assisted code reviews, improve workflows with LLM tooling, write automated tests, and contribute to architectural decisions as the platform scales.
Working in a lean team means real ownership from day one.
What We're Looking For
AI-assisted development capability: Demonstrable track record adopting and getting real leverage from AI-powered coding tools (Claude Code, Cursor, Copilot).
We want to see what you've actually built with them — not just that you've used them.
Django + DRF: Working experience building production services with Django (recent versions) and Django REST Framework.
PostgreSQL: Hands-on experience with schema design, indexing, and writing efficient queries.
REST API design: Comfort building well-structured RESTful APIs and collaborating with client-side teams on API contracts.
Cloud platform experience: Production exposure to GCP (preferred), AWS, or Azure — including basic understanding of secret management, deployment, and monitoring.
Engineering fundamentals: Solid grounding in security, performance, and clean code practices, with the judgment to critically review AI-generated output.
Collaboration: Strong written communication and ability to work autonomously in a cross-regional team.
Education: Bachelor's degree in Computer Science, Software Engineering, or equivalent practical experience.
Would be great if you are
Experience in healthcare, digital health, or regulated environments (familiarity with data privacy regimes such as PDPO, PDPA, or GDPR a strong plus).
Integration experience with third-party APIs across video, payments, clinical data standards, and logistics.
Direct experience integrating LLM APIs (Claude, OpenAI) into backend services.
Mobile-first product experience.
