> Staff engineer providing technical leadership across Brex's Travel & Expense domain (expenses, travel, policy, spend controls). Identify and drive cross-team technical problems, set architecture direction, raise engineering bar, and mentor without direct reports. Requires 8+ years experience with large-scale backend systems.

## Job Description

## 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.

## 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.

## Nice-to-Haves
- AI-forward mindset for building, reviewing, and operating systems.
