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.

• 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.

• Familiarity with our tech stack: TypeScript, Next.js, React, TailwindCSS, tRPC, Postgres, Temporal, AWS.

• The ability to get shit done end-to-end. From understanding users → proposing an idea → implementation → iteration.

• 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.
