This role offers the opportunity to tackle complex technical challenges, contribute to high-quality codebases, and collaborate with talented engineers who care deeply about building the right solutions. If you are a self-starter who thrives on turning ambiguous problems into clean, maintainable designs, we want to hear from you.

A day in the life

You might start by reviewing a design document for an upcoming feature, providing feedback that strengthens the architecture before implementation begins. Later, you pair with a teammate on a tricky code change, then shift to investigating an operational metric that looks off. You document your findings, propose a fix, and discuss tradeoffs with your team. Throughout, you balance building new capabilities with improving what already exists, keeping the customer experience front and center.
