- Build integrations with payment providers, compliance vendors and financial institutions, weighing build-versus-buy decisions on correctness and security.

- Design security-focused infrastructure covering authentication, encryption of sensitive data, audit logging and observability.

- Contribute to frontend work that makes complex legal and financial structures easier to understand.

- Own initiatives end to end, from early planning through release, and help define the long-term technical foundations of the company.
