About The Role

Expert software engineer with strong UI/UX skills, capable of handling backend features, working with a TypeScript-dominated tech stack, and thriving in a high-autonomy environment.

The job involves being an expert software engineer with a strong focus on UI/UX. The role requires the ability to independently handle backend features, although expertise in backend development is not mandatory. The candidate should possess elite communication skills, deep resilience, no ego, and product mastery. The engineering culture emphasizes optional code reviews, radical autonomy, high-bandwidth collaboration, direct feedback, and ruthless efficiency. The recruitment process includes a recruiter screening, a short one-on-one with Simon, a technical challenge, and a full-time contract with a one-month trial period. Benefits include opportunities for steep learning, potential for significant financial gain, ownership of work, unlimited PTO, and a supportive team environment. The role is suited for someone who is independent, intrinsically motivated, and has a bias for trust. The company values AI-first approaches and seeks candidates in the top percentile of their technologies.

A startup environment often feels like eating glass. And if someone decides to eat glass with us, they will get their slice of the pie. Earning your first $1M means enduring $1M worth of pain, but if you’re up for it, we’re here for you. We don’t hire people that aren’t obsessive, so the main question shifts from `if` to `when`. You’ll own your slice of the pie. You’ve probably heard stories from corporates about "extreme ownership" that turned out to be capped by a manager. We don’t have managers, you are the one responsible. You’ll have the entire team’s trust. The only limit is business reality; we want to earn money, not just be around.
