Sr. Founding Product Engineer
About the role
The Sr. Founding Product Engineer will be the sole technical owner of an AI-powered anxiety coaching application for an Australian health technology company. This role involves end-to-end responsibility for the product's engineering, including AI Coach development, backend systems, mobile and web delivery, release engineering, and ensuring privacy and security for sensitive health data. The engineer will work directly with a non-technical founder, plan and execute their own work, and use AI-first development practices with agentic coding tools. The position requires strong experience in LLM-based product development, backend engineering, React Native and React, and a product-focused mindset. The company, Teamified, is a global talent partner with a collaborative and flexible work environment, offering benefits such as health insurance, professional development, and flexible hours.
Must have
- Proven experience shipping LLM-based products to production: prompt architecture, conversation state machines, RAG/retrieval, evals, moderation and safety handling - not just API calls
- Strong backend engineering: Python, FastAPI (or similar), SQL/PostgreSQL, AWS; comfortable owning infrastructure, CI/CD and production operations solo
- Solid React Native and React: can ship and debug on both iOS and Android, including in-app purchase flows on both stores and Stripe on web
- Demonstrated AI-first development practice: daily use of agentic coding tools, with the judgement to review and own what they produce
- Product sensibility: a genuine eye for mobile and web UX; you notice broken layouts, bad copy and clumsy flows, and fix them
- Self-sufficient operator: track record of owning a product or major system end-to-end with minimal technical oversight; excellent written communication for a non-technical founder
- Care with sensitive data: experience (or demonstrable seriousness) with privacy, security and access controls around personal/health data
Nice to have
- Experience in mental health, health tech or other regulated/safety-critical consumer products
- Experience taking over a codebase from an agency or departing team
- Mobile release operations: App Store / Play Store review cycles, promo codes, staged rollouts
- Analytics and growth tooling: AppsFlyer, GA4, event taxonomy design, experiment frameworks
- Voice features (TTS/STT), push notification strategy, CRM/email platform integrations
