• We're building a new category of interactive entertainment powered by AI characters, image, video, and real-time experiences. We're one of the most-visited AI products globally, serving millions of users every day.
• We work in-person in Sydney, Australia, and hire globally.

How we work

• User-first: We build what people want. We invest time to understand our users and focus on adding value instead of extracting value.
• High agency, high ownership: We own outcomes end-to-end. When something goes wrong, we take responsibility and fix it.
• Urgency: We prioritize ruthlessly, increase leverage, and move at an exceptional pace.

What you'll do

You’ll join a small, talent-dense engineering team with significant ownership across product, infrastructure, and AI.

You won’t be handed narrowly-scoped tickets. You’ll work from problems and outcomes: understand what users need, decide what should be built, design the system, ship it, measure the result, and iterate.

• Design memory for month-long conversations. Decide how memories are written, ranked, and retrieved across billions of messages while fitting everything into a fixed context budget.
• Build the For You feed. Own retrieval, ranking, cold start, and experimentation end-to-end, with retention as the metric.
• Ship frontier models days after release. Evaluate and benchmark new models, figure out the economics of hosting them at scale, and find the best configuration for millions of users.

What you’ll bring

• A track record of shipping exceptional products at meaningful scale.
• Strong product and engineering judgment: knowing what to build, how to build it, and where to make tradeoffs.
• Hunger to win. You want high ownership, high expectations, and a lot of responsibility.

Our product stack includes TypeScript, Next.js, React, tRPC, Postgres, ClickHouse, Temporal, and AWS. Our inference stack is Python, serving LLMs, TTS, and diffusion image and video models on self-hosted GPUs.

What we offer

• Top-of-market compensation with meaningful equity upside.
• Real ownership from day one. Work on important problems and see the impact of what you ship.
• Fast-growing scope. As your impact grows, your responsibility and compensation should grow with it.
• A company card for food, coffee, tools, and anything that helps you do your best work.
• Daily team lunch and dinner at the office.
• An unlimited workspace budget to build your ideal setup.
• Visa sponsorship and relocation assistance for people moving to Sydney.

How we think about comp

We raise the ceiling for exceptional performers, not the floor. As your impact grows, your compensation should too.

• The listed range is cash + equity, with superannuation on top.
• We review compensation every 6 months.
• Bonuses reward past impact, and raises reflect your new level.
• Intro call: 15 minutes to align on the role and company.
• Founder interview: go deep on what you've built, how you think, and how you work.
• Technical interview: 1 hour of system design and technical discussion. No live coding.
• Paid work trial: spend 3 days with us in Sydney working on a real problem. We cover travel and accommodation, if needed.
