Staff Software Engineer, Travel & Expense

Brex • Seattle, WA

5d • Hybrid

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) that function as a single system for customers. The Staff Engineer will identify and solve critical problems that fall between teams, drive technical direction, and improve design and review processes. This is a leadership role without direct reports, focused on influencing and mentoring senior engineers and collaborating with existing Staff Engineers and Engineering Managers. The position is based in the Seattle office, operating in a hybrid environment requiring three days per week in the office (Monday, Wednesday, and Thursday), with an additional perk of up to four weeks of fully remote work per year.

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.
