## Job description

## ABOUT US

- 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 own our model inference stack end-to-end — serving our in-house and open-source models to tens of millions of users at low latency and high throughput, and squeezing every bit of performance out of our GPU fleet.

## EXAMPLE PROJECTS

- Ship a high-throughput inference server for our in-house models, serving millions of generations per day at <200ms latency.
- Squeeze more out of every GPU with batching, quantization, and custom CUDA kernels.
- Test and productionize LoRAs and our in-house models to serve 10s of millions of users.

## WHAT YOU'LL BRING

- 5+ years of experience building software at scale, with a focus on ML inference or GPU-accelerated systems.
- Deep familiarity with GPU inference: batching, quantization, and serving frameworks like vLLM, TensorRT, or Triton.
- The ability to get shit done end-to-end. From understanding users → proposing an idea → implementation → iteration.
- Hunger to win. This is not going to be easy.

## 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.

## OUR INTERVIEW PROCESS

1. Intro call: 15 minutes to align on the role and company.
2. Founder interview: go deep on what you’ve built, how you think, and how you work.
3. Technical interview: 1 hour of system design and technical discussion. No live coding.
4. Paid work trial: spend 3 days with us in Sydney working on a real problem. We cover travel and accommodation, if needed.
5. Offer: if it’s a strong fit, we move quickly.
