Job Description

Working closely with the Engineering Manager and Product Lead, you will be a Mid-level or Senior Fullstack Engineer who operates at the intersection of core product development and clinical application. As a Forward Deployed Engineer, you will serve as a technical accelerator for the engineering organization—designing, deploying, and refining end-to-end voice AI solutions that address complex user requirements with high velocity and precision. You will act as a primary technical liaison for our enterprise customers, bridging the gap between their complex infrastructure needs and our core platform to deliver seamless, scalable integrations within large healthcare environments.

Job Responsibility

  • Build end-to-end AI features: Architect and ship fullstack solutions (from React frontends to Python backend services) that leverage voice AI and LLMs to automate clinical workflows
  • Operationalize Voice AI: Implement and fine-tune audio processing pipelines, ensuring Automatic Speech Recognition (ASR) and LLM agents perform accurately in diverse medical environments
  • 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
  • Optimise for real-time interaction: Tune fullstack performance to handle real-time audio streaming and token generation, minimizing latency
  • 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

Requirements

  • Mastery of Fullstack fundamentals: proficient in Python and modern frontend frameworks (React/TypeScript), capable of owning a feature from database schema to UI interaction
  • Applied AI & Voice fluency: working knowledge of LLM integration (RAG, prompt engineering) and audio technologies (ASR, speech processing)
  • Pragmatic problem solving: balance engineering purity with the need for speed
  • Cloud fluency (AWS or GCP): can spin up own infrastructure (containers, serverless functions) and manage CI/CD pipelines
  • Rigorous testing in production: implement observability and feedback loops to monitor AI features in the wild

What we offer

  • 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
