Controller

About Engine Engine is the AI-native platform for intelligent travel. For a decade, Engine has built the proprietary technology and supply behind modern business travel, serving over 40,000 customers and nearly 2 million travelers, along with leading travel and AI companies that build on Engine's infrastructure. One system powers business travel, group travel, human agents, and AI agents. That work has earned recognition as one of Fast Company's Best Workplaces for Innovators (2025), TravelTech's Reservation Platform of the Year (2026), and one of Built In's Best Places to Work (2020–2026). We're looking for bold, ambitious people to help redefine how businesses manage and experience travel. Working here, you can expect exponential growth, an ambitious pace, full ownership, and high-caliber colleagues who push you to do the best work of your career. Every hire raises the bar. Come outpace the ordinary and build the future of travel with us. About the Role: Engine is a high-growth, multi-entity travel marketplace with multiple revenue streams, international operations, a company-branded charge card, and a disciplined 5-day close. Accounting here already runs lean and AI-forward. We are hiring a Controller to take it to the next level of excellence, building on the automation and AI already in place and scaling a modern close through Engine’s next phase of growth. This is not a maintenance role. We are looking for a decisive, high-judgment leader who can raise talent density, simplify how work gets done, and push our existing AI and automation further to create real operating leverage. The goal is not to build a larger function. It is to build a better one. You will report to the VP, Accounting and lead the core Accounting leadership team, including Assistant Controller / GL, AR and, Payroll, and Tax. The role has a meaningful runway to grow into broader scope as Engine grows. Your Mission Own the operating system of Engine’s accounting function: the talent bar, the integrity of the close, the control environment, and the pace of automation, so a lean team scales with the business without scaling headcount. Key Responsibilities: Raise the operating bar: Create a clearer, more accountable operating model across Accounting. Clarify decision rights, push ownership closer to the work, reduce unnecessary escalation, and move priorities quickly from discussion to execution. Increase talent density: Build a high-performing leadership team that operates with strong judgment and increasing independence. Set a clear performance bar, develop strong managers, address capability gaps directly, and make thoughtful talent upgrades where needed. Scale AI and automation: Build on the automation and AI already in place across Accounting and take it further. Partner with Systems and cross-functional teams to automate high-volume and repetitive work, apply AI to reconciliations, documentation, anomaly detection, and management visibility,…
