Job summary

Qualifications

• 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.

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.
