Staff Software Engineer, Travel & Expense
About The Position
Brex is the intelligent finance platform that enables companies to spend smarter and move faster. By combining global corporate cards and banking with intuitive spend management, bill pay, and travel software, Brex enables founders and finance teams to accelerate operations, gain real-time visibility, and control spend effortlessly. Brex’s AI-native automation and world-class service eliminate manual expense and accounting tasks for customers so they can focus on what matters most. Tens of thousands of the world's best companies run on Brex. Working at Brex allows you to push your limits, challenge the status quo, and collaborate with some of the brightest minds in the industry. We’re committed to building a diverse team and inclusive culture and believe your potential should only be limited by how big you can dream. We make this a reality by empowering you with the tools, resources, and support you need to grow your career. Engineering at Brex is about building systems that scale with speed and intention. Our teams span Software, Data, Security, and IT, and operate with high autonomy and deep collaboration. We tackle hard technical problems, own our outcomes, and push for excellence at every level — from architecture to deployment. It's an environment where engineering is a craft, and builders become leaders. 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.
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
- Equity and other forms of compensation may be provided as part of a total compensation package.
