About the role
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.
Senior Staff Engineer on the Growth team responsible for setting technical vision, modernizing the data and activation stack, leading cross-pod architecture initiatives, and turning AI opportunities into scalable platforms.
