Software Engineer (Model Deployment)

ABOUT US

• At coreflow, we're redefining entertainment with AI. We're one of the fastest-growing startups globally, serving 20 million users in our first year. We're an in-person company based in Sydney, Australia.
• We're guided by a set of principles that are foundational to our work and drive every decision:
• User-first: We build things that people want. We invest time to understand our users and focus on adding value instead of extracting value.
• High agency, high ownership: We're responsible for the pieces we own, end-to-end. We own every mistake, figure out what went wrong, and fix it. We don't blame anyone or anything else.
• Urgency: This is a once-in-a-lifetime opportunity. We prioritize well, find ways to increase leverage, and move at an inspirational pace.

WHAT YOU'LL DO

• You'll own how our models reach production — building the deployment and serving platform that ships new models, LoRAs, and updates to tens of millions of users safely and continuously.

EXAMPLE PROJECTS

• Build a zero-downtime rollout system for new models and LoRAs across hundreds of GPUs.
• Automate the path from a trained model to production — packaging, versioning, canarying, and rollback.
• Orchestrate hundreds of GPUs to serve millions of image generations per day.

WHAT YOU'LL BRING

• 5+ years of experience building software at scale, with a focus on ML deployment, infrastructure, or platform engineering.
• Experience shipping models to production: containerization, orchestration (Kubernetes), autoscaling GPU workloads, and CI/CD.
• 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

• Competitive compensation with meaningful upside.
• A company card for food, coffee, tools, and anything that helps you operate at a high level.
• Daily team lunch and dinner at the office.
• Unlimited workspace budget. Build your ideal setup.
• Real ownership and impact from day one.
• Based in Sydney and hiring globally. We sponsor visas and offer relocation assistance to help you make the move.

HOW WE THINK ABOUT COMP

Our overarching philosophy is to raise the ceiling for our best performers, not the floor. We pay based on the value you add to the company.

• The range listed for this role is total comp: cash plus equity combined, with superannuation paid on top.
• We re-evaluate compensation every 6 months. Bonuses are backward-looking; raises are forward-looking.
• A bonus rewards work you've already done, like exceptional output or consistently performing above your level.
• A raise reflects that you've moved up. It resets your baseline to match the higher level you're now operating at.
