Principal Systems Architect

About Engine At Engine, we’re transforming business travel into something personalized, rewarding, and simple. For too long, managing travel and spend has been overwhelming and fragmented — we’re here to change that. We believe the future of travel should be seamless and powered by technology that delights customers at every step. That’s why we’re building a platform that brings together corporate travel, a powerful charge card, and modern spend management in one place. To make this vision real, we’re looking for exceptional, mission-driven people to help redefine how businesses manage and experience travel. More than 30,000 companies already rely on Engine to support over 1 million travelers and billions in annual bookings each year. Cash flow positive with rapid growth, we pair exclusive Engine-only rates, industry-leading rewards, and intelligent automation to help businesses save money while delivering world-class personalization and convenience. Backed by Telescope Partners, Blackstone, and Permira, Engine has been recognized as one of the fastest-growing travel and fintech platforms in North America, with honors including the Deloitte Fast 500 and Built In’s Best Places to Work. About the Role As Principal Systems Architect for GTM & Business Systems at Engine, you'll own the end-to-end architecture of the platforms that power how we go to market — Salesforce, Tray.io, Outreach, Slack, ZoomInfo, AWS Connect, and the integration fabric that connects them to Snowflake, our product stack, and our engineering systems. You're not maintaining someone else's setup. You're designing the blueprint, shipping production-grade automation, and setting the technical standard for how GTM systems operate at scale. This is a senior individual contributor role. You architect, you build, and you ship. You partner directly with Sales, Marketing, RevOps, Product, and Engineering to translate ambiguous business problems into durable, metadata-driven systems that scale faster than headcount. What You'll Own Salesforce Platform Architecture. Own the end-to-end design of Engine's Salesforce stack — Sales Cloud, Service Cloud, Data Cloud, AgentForce, and Experience Cloud. Architect declarative-first, metadata-driven solutions (Flow, Permission Sets, TriggerAction patterns) that minimize technical debt and maximize admin velocity. Set the standard for governor limits, bulkification, sharing, and security across the org. Tray.io Orchestration & Integration Layer. Architect the middleware fabric that connects Salesforce to Outreach, ZoomInfo, Snowflake, Customer.io, AWS Connect, NetSuite, and dozens of GTM tools. Own workflow design, error handling, idempotency, retries, and observability. Make the call on when to use Tray vs. native Salesforce automation vs. Apex vs. event-driven patterns through Kafka. Sales Engagement & Outreach Architecture. Own the technical architecture of Outreach — sequences, triggers, mappings, ZoomInfo enrichment, and the bi-directional sync with Salesforce. Design the signal layer that drives AE/AM workflows, lead routing, and the AI-prioritized actions that show up in the Cockpit every morning. Engineering & Product Interface. Serve as the technical translator between Business Systems and Engineering. Partner with Product and Engineering on event streams (Kafka, webhooks), shared data contracts, Snowflake pipelines, and the customer-facing surfaces that touch Salesforce (Help Center, EVA chat/voice, Atlas). Own the integration patterns that let GTM systems consume product data without becoming a bottleneck. Slack as the GTM Control Plane. Architect Slack as the operational surface for GTM — automated pulse reports, deal alerts, approval workflows, case routing notifications, and incident response. Build Slack-native experiences (Block Kit, slash commands, modals) that move work out of inboxes and into the channels where decisions actually happen. AI & Agent Architecture. Own the systems-side of Engine's AI initiatives —
