Software Engineer (Model Inference)

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.
