We are looking to hire a Senior / Lead Software Engineer who wants to stay close to the code while shaping how a squad delivers.

What Youll Be Doing Designing and building highly scalable backend services that power complex financial workflows Working across TypeScript, Go, and C#, with modern frontend interaction via React Taking a cloud-first, API-led approach, primarily within AWS Contributing to architectural decisions while remaining grounded in delivery Helping your squad plan effectively using a now / next / later mindset Championing reliability, observability, and supportability.
