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. Your Mission You own GMV for Engine X - our new business credit card that is built on top of Engine's travel platform. That means building the acquisition model from the ground up, identifying the channels and motions that drive real results, and scaling what works. You'll bring a point of view, test it rigorously, and iterate fast. This is more than a growth role. You'll help shape what we build, how we position it, and where Engine X goes next. You'll have the autonomy to move quickly and the cross-functional support to do it well. Key Responsibilities • Own the Strategy. You're the GM for Engine X acquisition. Decide what to test, what to scale, and what to move on from. Translate ambitious targets into concrete plans, channels, and experiments — and back your decisions with data. • Build the Acquisition Engine. Stand up the programs, infrastructure, and systems that make Engine X growth predictable and repeatable. Paid, lifecycle, partnerships, sales-assist, content, organic — build the playbook from scratch and grow the team around it as you scale. • Ship the Work. Drive large, ambiguous projects forward without losing momentum. Where you have the skills, execute directly. Where you don't, pull in the right people from growth, product, data, or sales. You're a multiplier across the org. • Test What's New. Engine X is entering one of the most active fintech markets in years. Bring fresh thinking to how we reach prospects — test messaging, paid programs, partnerships, and GTM motions, and bring back what works. • Partner Cross-Functionally. Work directly with Product on roadmap and positioning. Partner with Data to instrument, measure, and learn. Align with Sales on ICP, motion, and handoff. Bring a clear, data-backed perspective to the executive team on where to invest. • Lead AI-Native Growth. Engine's growth team uses AI as a core part of how we work. Leverage Claude Code, LLMs, and modern tooling to move faster, build smarter personalization, and run more tests — without depending on engineering or ops. Qualifications • Fintech Experience. You've marketed or sold fintech products — business cards, banking, lending, expense management, or similar. You understand the buyer, the compliance considerations, and what makes fintech GTM distinct from generic B2B SaaS. • Owner's Mentality. You operate like a GM. You take ambiguous targets, build the plan, and deliver the outcome. • Strong Data Proficiency. You pull your own data, build your own models, and back your strategy with numbers. SQL, Amplitude, and Snowflake are part of your regular workflow. • AI Fluency. You use AI to multiply your output — not as a novelty, but as a genuine part of how you work. You know where LLMs add leverage and where they don't. • Customer-Centric Thinking. You've built acquisition motions tha
