Job Description
A well-funded, early-stage AI product company based in Melbourne, with real revenue, enterprise customers, and a roadmap that's outgrown the size of the team building it. Small engineering group, founders in the room daily, and a lot of ground still to cover.

Role and responsibilities
n
You'll work on real-time conversational AI where speed is the whole game: voice in, context understood, an answer back fast enough that it feels natural rather than laggy. That single constraint shapes most of the engineering decisions here.
n
Expect to work across real-time audio at scale (turn-taking, interruptions, knowing when someone's actually finished speaking, all of it holding up under real load), agent context and knowledge (becoming the expert on a customer's product and surfacing the right answer inside a tight latency budget), and live understanding of what's happening on a user's screen to know when the agent should speak.
n
This is a generalist role more than a narrow AI specialist one. You'll need real product taste,



comfort shipping something imperfect and iterating fast, and the ability to explain a trade-off clearly to a non-technical audience, including a customer's engineering team.
n
Key technical skills
n
n
Deep in one of backend, frontend or infra, and genuinely capable in the other two
n
Robust fundamentals: system design, data flow, trade-offs, not just code to spec
n
Real intuition for what LLMs do reliably versus what only holds up in a demo, production agent experience is a bonus not a filter
n
Python matters most, TypeScript, Kubernetes and cloud infra all feature
n
Real-time, voice, video, streaming or low-latency systems experience is a strong plus, not required

Melbourne. Hybrid, 3 days a week in office. Great culture and meaningful early-stage equity. Multiple roles available at Senior and Principal level.
