About The Position

Brex is seeking a Staff Software Engineer to join their Travel & Expense domain. This role operates across multiple engineering teams (expenses, travel, policy, and spend controls) to identify and solve critical problems that fall between teams. The position is a leadership role without direct reports, focusing on setting technical direction, improving design and review processes, and acting as a force multiplier for engineers and Engineering Managers. The ideal candidate will have a strong track record of technical leadership, experience with large-scale backend systems, and a collaborative approach. This role offers the influence of a senior technical leader without the responsibilities of management.

Requirements

• 8+ years of software engineering experience, with a track record of technical leadership across multiple teams or a group.
• Demonstrated ability to identify and drive ambiguous, cross-cutting problems to resolution without a defined charter.
• Deep experience designing and operating large-scale backend systems in production.
• Strong collaboration skills; a track record of raising the bar for engineers around you and working effectively with both ICs and managers.
• Excellent written and verbal communication.

Responsibilities

• 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.

Benefits

• Global corporate cards
• Banking
• Intuitive spend management
• Bill pay
• Travel software
• AI-native automation
• World-class service
• Tools, resources, and support for career growth
• Equity and other forms of compensation may be provided as part of a total compensation package.
