We're looking for a Staff Full Stack Software Engineer with at least 8 years of full-stack development experience, specifically with a strong backend lean and a proven track record of architecting and implementing complex systems. You should be comfortable leading a team, distilling large problems, and unblocking junior to mid-range engineers in a high-velocity startup environment. Bonus points if you have experience building or maintaining billing/monetization systems from scratch.

What you'll do:

Architect and optimize complex systems that span across the backend (AWS Lambda, TypeScript, Go) and the frontend (Next, React, TypeScript).

Take ownership of the user management platform, including the developer portal, billing and payment systems, notifications, and dashboard, ensuring critical customer accounts remain stable and performant.

Work closely with founders, product owners, and go-to-market teams to gather requirements and translate them into well-architected solutions.

Drive technical decisions around frontend architecture, state management, and API design.

Lead critical initiatives, mentor engineers, and influence architecture from day one, with a clear path toward Engineering Leadership.

Ensure system scalability, performance, and reliability across the stack, particularly for event-driven systems.
