About The Position

Brex is seeking a Staff Engineer to join their Travel & Expense domain. This is a leadership role without direct reports, focused on identifying and solving high-impact technical problems that span multiple engineering teams. The ideal candidate will set technical direction, improve design and review processes, and act as a force multiplier for engineers and Engineering Managers. This role offers the influence of a senior technical leader without the responsibilities of direct management, with opportunities to shape the organization's technical strategy and investments.

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.
