Staff Software Engineer (Travel & Expense)

• Travel & Expense is one of the highest-leverage domains at Brex, and it spans several engineering teams — expenses, travel, policy, and spend controls — that have to work as one system for customers. We’re looking for a Staff Engineer who operates across all of them. You won’t own a single team or service. Your mandate is to find the most important problems across T&E — the ones that fall between teams, the ones nobody is holding — and drive them to a solution
• This is a leadership role without direct reports. You’ll set technical direction across the group, raise the bar in design and review, and be a force multiplier for the engineers and EMs you work alongside. You’ll partner closely with our existing Staff Engineers as peers, and you’ll have a seat at the T&E leadership table to help shape where the org invests. If you want the influence of a senior technical leader without moving into management, this is that role
• Identify the highest-impact technical problems across Travel & Expense — including the cross-team gaps that individual teams can’t see or own — and drive them to resolution
• Set and raise the technical bar across the group through design reviews, architecture decisions, and hands-on work where it matters most
• Partner as a peer with existing Staff Engineers and with EMs across expenses, travel, policy, and spend controls to align on direction and unblock execution
• Act as a force multiplier: mentor senior engineers, improve how teams design and ship, and grow the next generation of technical leaders
• Bring an AI-forward mindset to how the org builds, reviews, and operates
• Contribute directly to the group’s technical strategy and inform where leadership invests
