<div class="content-intro"><h3><strong>About Engine</strong></h3> <p>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.<br><br>That work has earned Engine recognition as TravelTech's Reservation Platform of the Year (2026), a spot on Inc.'s Power Partners list (2026), and one of Built In's Best Places to Work (2020–2026).<br><br>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.<br><br>Come outpace the ordinary and build the future of travel with us.</p></div><p>As a Senior Infrastructure Engineer, you're a senior voice on Engine's central infrastructure team — the group that owns the substrate every product team at Engine ships on top of. Your work is horizontal by default: the patterns you design, the modules you ship, and the paved roads you maintain are used across every business vertical.</p> <p>You'll be hands-on with:</p> <ul> <li><strong>Cloud infrastructure</strong> — the AWS accounts, networking, deployment patterns, and operational tooling that Engine's product teams depend on day to day.</li> <li><strong>Terraform</strong> — designing and evolving the shared module registry that feature teams across the company consume.</li> <li><strong>CI/CD</strong> — pipeline templates and GitHub Actions workflows that set the standard for how code ships at Engine.</li> <li><strong>Reliability & observability</strong> — Datadog dashboards, SLO frameworks, and incident response tooling used org-wide.</li> <li><strong>Security & networking</strong> — Cloudflare configuration, IAM boundaries, and secret management as platform-level primitives.</li> <li><strong>Cost visibility</strong> — building the tooling and reporting that helps every team understand and act on what they own and spend.</li> </ul> <p>You'll partner closely with feature teams across verticals — not by embedding with them, but by running a tight feedback loop: understanding their friction, prioritizing what deserves a paved road, and shipping platform capabilities that make the right path the easy path.</p> <h3>What You'll Do</h3> <ul> <li>Set the technical direction for a major area of Engine's infrastructure over a multi-quarter horizon — where it's headed, what you're deliberately not building, and how platform investments compound rather than fragment.</li> <li>Lead multiple infra initiatives in parallel, coordinating across the central team and with the feature teams who'll adopt what you build.</li> <li>Design and ship the Terraform modules, pipeline patterns, and operational tooling that product teams adopt because they're better than the alternative — not because they're mandated.</li> <li>Separate signal from noise across the feature-team requests that land on the central team. Decide what deserves a paved road, what belongs in team-owned space, and what shouldn't be built at all.</li> <li>Own the critical work: incident response, on-call quality, deployment reliability, vendor integration health.</li> <li>Shape the guidelines, tools, and methods every engineer at Engine uses — and coach the feature engineers who apply them.</li> <li>Represent the infra team in cross-functional conversations with product and engineering leadership. Our team meets twice a week — that's where you'll share what's shipping, align on priorities, and pressure-test decisions.</li> <li>Reduce the SDLC step-function count across Engine. Every approval gate, every "ask infra first" workflow is a tax — your job is to lower it.</li> </ul> <h3>What We're Looking For</h3> <p><strong>Required</strong></p> <ul> <li>6+ years building and operating production cloud infrastructure, with deep AWS expertise (multi-account, networking, IAM, security boundaries).</li> <li>Expert-level Terraform — you've designed reusable modules and have opinions about state, drift, and execution patterns.</li> <li>Strong CI/CD background — GitHub Actions, reusable workflows, OIDC, secret management.</li> <li>A track record of shipping platform infrastructure that feature teams actually adopt — you know how to build for internal customers without losing sight of what makes something feel like a product.</li> <li>A bias toward enabling teams over gatekeeping. You'd rather build the paved road than approve the off-road permits.</li> <li>Experience leading technical direction across multiple teams — making the trade-offs precisely, communicating them clearly, and bringing other engineers along.</li> <li>Instinct for when a problem deserves a central solution and when it should stay with the team that hit it.</li> </ul> <p><strong>Strongly preferred</strong></p> <ul> <li>Cloudflare (WAF, DNS, zero-trust/WARP) at production scale.</li> <li>Datadog, JFrog, or comparable vendor integration experience.</li> <li>Background in cost observability or FinOps tooling.</li> <li>History of working on a platform team that serves interna
