THE ROLE
Navigator is building the definitive travel commerce media network - aggregating first-party travel intent data from airline, OTA, and metasearch partners, and activating it programmatically across a growing publisher and advertiser ecosystem.
We are Series A-backed, scaling aggressively, and moving toward Series B.
We're looking for a senior individual-contributor engineer to own the deep technical build of Navigator's commerce media infrastructure: the clean room, identity resolution layer, agentic bot stack, and the systems that connect our data to activation and measurement.
This is a hands-on architecture and build role, not a management position - you'll set technical direction and do the work yourself, reporting directly to the CEO.
This role works closely with the Director of Commerce Media Partnerships & Infrastructure, who owns vendor relationships, contracting, and the commercial side of the stack.
You own the engineering: the systems get built, integrated, and kept running by you.
- WHAT YOU'LL OWN
- Clean Room & Identity Infrastructure
- Own and evolve Navigator's GCP-hosted clean room - architecture, data pipelines, and performance.
- Build and maintain the identity resolution layer that matches hashed emails and other identifiers across our data partner network into a unified, addressable identity graph.
- Manage technical integration of identity partners across our resolution waterfall (Live Ramp, Experian, ID5, On Audience, and emerging regional partners), including match-rate testing and partner evaluation for underserved regions such as APAC.
- Work toward Navigator's long-term identity graph vision - a proprietary, travel-specific identity layer built on aggregated first-party signals.
- Ensure all identity and clean room infrastructure meets privacy, security, and data governance standards.
- Agentic Bot Stack
- Own the architecture, reliability, and expansion of Navigator's agentic infrastructure - Sync Bot, Provision Bot, Margin Bot, and Pacing Bot - running on Claude via MCP.
- Build new agentic capability as Navigator extends automation deeper into campaign operations, partner onboarding, and margin management.
- Ensure the bot stack integrates cleanly with the clean room, the identity layer, and downstream activation systems.
- DSP, SSP & Activation Integration
- Own the technical integration of Navigator's activation stack - DV360, Stack Adapt, and Index Exchange - ensuring reliable, well-instrumented pipelines from audience to activation.
- Build and maintain the technical connective tissue between Navigator's data layer and each platform's API, including audience syncs, bidding signals, and reporting feeds.
- Partner with the Director of Commerce Media Partnerships & Infrastructure on new vendor integrations - they own the commercial relationship and contract; you own the technical implementation and its reliability.
- Data Infrastructure & Measurement
- Build the technical foundation for closed-loop attribution and incrementality measurement across clean-room partnerships.
- Ensure first-party intent signals from data partners are structured, unified, and ready for activation at scale (3bn+ signals and growing).
- Define engineering standards for data quality, pipeline monitoring, and system reliability across the stack.
WHAT WE'RE LOOKING FOR
- Deep hands-on experience building data infrastructure, identity resolution, or clean room systems - ideally in adtech, martech, or a comparable data-intensive environment.
- Strong experience with GCP (Big Query, Pub/Sub, Cloud Run or equivalent) or a comparable cloud data stack.
- Comfort working with DSP/SSP integrations and programmatic ecosystems is a strong plus, though not a strict requirement.
- Experience with or strong interest in agentic/LLM-based automation - you'll be extending a live agentic bot stack, not just reading about one.
- A track record of owning systems end-to-end as a senior individual contributor - architecture through to production reliability - without a team around you.
- Comfortable operating in a small, fast-moving company where you'll build, ship, and support your own systems.
- WHAT NAVIGATOR OFFERS
- A rare opportunity to architect a commerce media technology stack from the ground up, with commercial traction and partnerships already in place.
- Direct access to and reporting line with the CEO & Founder - your work will be highly visible at the most senior level of the business.
- A genuinely agentic, AI-native engineering environment - not a legacy stack retrofitted with AI features.
- The scope to shape technical direction as Navigator scales through Series B and beyond.
