Application Security Engineer [Remote-US]
Quanata, LLC
Engine is the all-in-one travel and spend management platform trusted by 38K+ businesses and groups representing 1.8M+ travelers. We're the retailer and the rails of business travel, one of the fastest-growing companies in travel tech, built on a decade of proprietary technology, supply, and pricing no one else can replicate. Other travel and AI companies run on our infrastructure to book real trips, hold rates, and move payments, without building any of it themselves. We built it, AI-forward at every layer, from how travelers book to how the rails run.
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.
We're hiring a VP of Security to own security at Engine end to end: strategy, engineering, operations, and the trust posture that carries us through future funding and beyond. This is not a maintain-the-program role. The program is healthy: clean SOC 2 and PCI audits, established AppSec, SecOps, and CloudSec functions, modern tooling across the stack. The mandate is to build what comes next.
What comes next is AI. Agents inheriting human credentials in cloud environments with real access sprawl. Prompt injection and data exfiltration attempts against customer-facing AI surfaces. Shadow AI usage across every function of the business. Non-engineers shipping AI-built software that never touches a review path. Adversaries using the same models we do, at machine speed. We need a leader who sees this wave clearly, has strong conviction about what to build, and can stand up net-new AI security capability while keeping the fundamentals sharp.
This role reports directly to the SVP of Engineering and AI and operates as a peer to senior engineering leadership. You'll represent security to the executive team, the board, and enterprise customers.
Most VP of Security roles are about maturing what exists. This one is about defining how an AI-native company defends itself while the threat model is still being written. You'll inherit a clean foundation, approved headcount, executive air cover, and a company that treats AI as its operating model rather than a feature. Join us on this mission to reshape how businesses experience travel, and help build the security foundation every AI at Engine runs on.
We accept applications for this role on an ongoing basis. We review applications as they are received and encourage interested candidates to apply early.
