NAVIGATOR

AI-native travel commerce media network

Solutions Architect, Commerce Media

Reports to: CEO & Founder

Location: London (hybrid)

Type: Full-time

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

\n
• Own and evolve Navigator's GCP-hosted clean room - architecture, data pipelines, and performance.
\n
• 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.
\n
• 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.
\n
• Work toward Navigator's long-term identity graph vision - a proprietary, travel-specific identity layer built on aggregated first-party signals.
\n
• Ensure all identity and clean room infrastructure meets privacy, security, and data governance standards.
\n

Agentic Bot Stack

\n
• Own the architecture, reliability, and expansion of Navigator's agentic infrastructure - SyncBot, ProvisionBot, MarginBot, and PacingBot - running on Claude via MCP.
\n
• Build new agentic capability as Navigator extends automation deeper into campaign operations, partner onboarding, and margin management.
\n
• Ensure the bot stack integrates cleanly with the clean room, the identity layer, and downstream activation systems.
\n

DSP, SSP & Activation Integration

\n
• Own the technical integration of Navigator's activation stack - DV360, StackAdapt, and Index Exchange - ensuring reliable, well-instrumented pipelines from audience to activation.
\n
• 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.
\n
• 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.
\n

Data Infrastructure & Measurement

\n
• Build the technical foundation for closed-loop attribution and incrementality measurement across clean-room partnerships.
\n
• Ensure first-party intent signals from data partners are structured, unified, and ready for activation at scale (3bn+ signals and growing).
\n
• Define engineering standards for data quality, pipeline monitoring, and system reliability across the stack.
\n

WHAT WE'RE LOOKING FOR

\n
• Deep hands-on experience building data infrastructure, identity resolution, or clean room systems - ideally in adtech, martech, or a comparable data-intensive environment.
\n
• Strong experience with GCP (BigQuery, Pub/Sub, Cloud Run or equivalent) or a comparable cloud data stack.
\n
• Comfort working with DSP/SSP integrations and programmatic ecosystems is a strong plus, though not a strict requirement.
\n
• Experience with or strong interest in agentic/LLM-based automation - you'll be extending a live agentic bot stack, not just reading about one.
\n
• A track record of owning systems end-to-end as a senior individual contributor - architecture through to production reliability - without a team around you.
\n
• Comfortable operating in a small, fast-moving company where you'll build, ship, and support your own systems.
\n

WHAT NAVIGATOR OFFERS

\n
• A rare opportunity to architect a commerce media technology stack from the ground up, with commercial traction and partnerships already in place.
\n
• Direct access to and reporting line with the CEO & Founder - your work will be highly visible at the most senior level of the business.
\n
• A genuinely agentic, AI-native engineering environment - not a legacy stack retrofitted with AI features.
\n
• The scope to shape technical direction as Navigator scales through Series B and beyond.
