About The Position

We are hiring a Staff Software Engineer to own and drive the highest-leverage technical work across Blitzy's backend platform, infrastructure, and AI product surface.

This is a hands-on technical role. You will be expected to stay close to the code, make credible architectural decisions, and hold the bar on engineering quality across the systems you touch. We are looking for an engineer who knows how to identify the highest-leverage problems, unblock the people around them, and drive outcomes that matter to customers.

Experience building platforms or tools used by other engineering teams, not just end customers, is a plus

Serve as a technical escalation point for complex production issues, driving postmortems and fixes that prevent them from recurring
Champion improvements across the enterprise software development lifecycle, advocating for better ways of building, deploying, and operating software company-wide
Build demos, prototypes, examples, and technical content that create technical champions and help customers and colleagues adopt new technologies
Collaborate closely with engineers, designers, sales executives, and other stakeholders to deliver exceptional outcomes in an in-person environment
Communicate openly, share the rationale behind important technical decisions, and actively seek feedback to keep the team aligned and moving forward
Mentor and unblock other engineers, modeling the technical judgment we want the whole team to have
