Who You Are

Full-stack generalist (not a narrow specialist) Ex-founder or early-stage startup DNA is a big plus You build things outside of work You don't create noise — you create solutions You're senior enough to operate without hand-holding You handle uncertainty without spiraling We don't have capacity to grow mid-level engineers. We need someone who can carry weight immediately.
