About the role

•⁠ ⁠We're looking for a hands-on CTO to take full ownership of our technology. You'll set the technical direction, build and ship the product day to day, and grow the engineering function as we scale.

•⁠ ⁠This is a founding-level technical role for someone who wants to own the stack end to end - from AI/ML systems to the app our customers use.

What you'll do

•⁠ ⁠Own the entire technology strategy, architecture, and roadmap

•⁠ ⁠Build and ship across the full stack - frontend, backend, infrastructure, and data

•⁠ ⁠Design, train, and productionize AI/ML systems at the core of the product

•⁠ ⁠Make the hard build-vs-buy, tooling, and scaling calls - and stand behind them

•⁠ ⁠Set engineering standards, hire the early team, and shape technical culture

•⁠ ⁠Partner with the founders on product direction, priorities, and company strategy

What we're looking for

•⁠ ⁠Proven experience shipping production software as a senior engineer, lead, or founder

•⁠ ⁠Deep hands-on AI/ML experience - building, training, and deploying models in real products

•⁠ ⁠Strong full-stack ability; comfortable across frontend, backend, and infrastructure

•⁠ ⁠A track record of taking ownership and driving outcomes with little oversight

•⁠ ⁠Pragmatic judgment about what to build, what to defer, and when to move fast

•⁠ ⁠Ability to lead a small team and set the technical bar as we grow

Nice to have

•⁠ ⁠Founder or early-stage startup experience

•⁠ ⁠Experience scaling systems and teams from zero to one

•⁠ ⁠Depth in data platforms and LLMs

What we offer

•⁠ ⁠Competitive salary, based on experience

•⁠ ⁠Meaningful equity and a genuine seat at the table

•⁠ ⁠Full ownership of the technical vision

•⁠ ⁠Work how and where you want, fully flexible on hours and location.
