Heidi - Senior Software Engineer (AI Voice Agents)

• Build end-to-end AI features: Architect and ship fullstack solutions (from React frontends to Python backend services) that leverage our voice AI and LLMs to automate clinical workflows. • Build end-to-end AI features: • Operationalize Voice AI: Implement and fine-tune audio processing pipelines, ensuring our Automatic Speech Recognition (ASR) and LLM agents perform accurately in diverse, real-world medical environments. • Operationalize Voice AI: • Bridge the gap between model and product: Translate complex feedback from clinicians into technical solutions, rapidly prototyping and deploying improvements to model behavior, prompting strategies, and audio handling. • Bridge the gap between model and product: • Optimise for real-time interaction: Tune fullstack performance to handle real-time audio streaming and token generation, minimizing latency so clinicians have a seamless conversational experience. • Optimise for real-time interaction: • Partner with implementation and clinical teams: Shorten the feedback loop by shipping critical integrations and feature requests from concept to production in days, not quarters. • Partner with implementation and clinical teams: • What we will look for: • Mastery of Fullstack fundamentals: You are equally proficient in Python and modern frontend frameworks (React/TypeScript), capable of owning a feature from the database schema to the UI interaction. • Mastery of Fullstack fundamentals: • Applied AI & Voice fluency: You have a working knowledge of LLM integration (RAG, prompt engineering) and audio technologies (ASR, speech processing) and know how to build around their probabilistic nature. • Applied AI & Voice fluency: • Pragmatic problem solving: You balance engineering purity with the need for speed; you know when to build a robust system and when to ship a tactical solution to unblock a customer. • Pragmatic problem solving: • Cloud fluency (AWS or GCP): You can spin up your own infrastructure (containers, serverless functions) and manage CI/CD pipelines to get your code into the hands of users independently. • Cloud fluency (AWS or GCP): • Rigorous testing in production: You understand that "works on my machine" isn't enough; you implement observability and feedback loops to monitor how your AI features perform in the wild. • Rigorous testing in production: • What do we believe in? • Heidi builds for the future of healthcare, not just the next quarter, and our goals are ambitious because the world’s health demands it. We believe in progress built through precision, pace, and ownership. • Live Forever - Every release moves care forward: measured, safe, and built to last. Data guides us, but patients define the truth that matters. • Live Forever - • Practice Ownership - Decisions follow logic and proof, not hierarchy. Exceptional care demands exceptional standards in our work, our thinking, and our character. • Practice Ownership - • Small Cuts Heal Faster - Stability earns trust, speed delivers impact. Progress is about learning fast without breaking what people depend on. • Small Cuts Heal Faster - • Make others better - Feedback is direct, kindness is constant, and excellence lifts everyone. Our success is measured by collective growth, not individual output. • Make others better - • Our mission is clear: expand the world’s capacity to care, and do it without losing the humanity that makes care worth delivering. • Flexible hybrid working environment, with 3 days in the office. • Additional paid day off for your birthday and wellness days • Special corporate rates at Anytime Fitness in Melbourne, Sydney tbc. • A generous personal development budget of $500 per annum • Learn from some of the best engineers and creatives, joining a diverse team • Become an owner, with shares (equity) in the company, if Heidi wins, we all win • The rare chance to create a global impact as you immerse yourself in one of Australia’s leading healthtech startups • If you have an impact quickly, the opportunity to fast track your startup career! • Help us reimagine primary care and change the face of healthcare in Australia and then around the world.
