Principal Product Manager, HTS API Marketplace

Hopper is seeking a Principal Product Manager to build the HTS API Marketplace, the commercial and developer-facing platform for enterprise partners to access lodging and car capabilities. The role will define product packaging, pricing, partner and developer experiences, go-to-market, and marketplace revenue while coordinating with capability teams and cross-functional partners.

Responsibilities:

• Define what the HTS API Marketplace is: how capabilities are structured, packaged, and priced across a portfolio spanning HTS Connect, Search Polygons, Autocomplete, Ranking, Content & Property Mapping, Room Mapping, Deduplication/Auction, Pricing, Extranet, Taxes, and Custom Deals Engine
• Coordinate with capability PMs — who own the underlying technical systems — to understand each capability's roadmap, constraints, and customization surface, and translate that into externally-consumable API products
• Own the commercial model for the marketplace: platform vs. variable fee decisions, take rate structure per capability, enterprise packaging, and the custom deals framework for large partners with differentiated customer segments
• Build the developer and partner experience from scratch: API specifications, partner onboarding flows, documentation standards, sandbox environments, and integration tooling that minimizes time-to-first-value
• Use AI tools and rapid prototyping to test ideas quickly — mock API responses, prototype partner portals, simulate pricing and ranking configurations — before committing engineering resources
• Establish the go-to-market motion for the marketplace: work with Commercial to identify the right partners for each capability, sequence launches, and define what a successful commercial rollout looks like
• Own the marketplace revenue P&L: model and track GBV, take rate, and per-capability unit economics in partnership with Finance

Requirements:

• 7+ years of Product Management experience, with at least one 0-to-1 product you built from concept to commercial launch
• Demonstrated experience building developer-facing or B2B marketplace products, including ownership of API product design, developer experience, and commercial packaging for enterprise customers
• AI-native working style: you use LLMs and vibe coding as first-line tools for prototyping, not as novelties
• You have built working demos, mockups, or proof-of-concepts using AI before handing work to engineering
• Strong understanding of marketplace economics: take rates, supply-side incentives, demand-side optimization, and the design of platform vs. variable commercial models
• Ability to coordinate effectively across multiple product teams — you can synthesize roadmaps, surface dependencies, and drive cross-team alignment without owning the underlying engineering
• Experience working with external enterprise partners: translating commercial needs into product requirements and managing partner expectations through multi-phase rollouts
• Strong fluency with SQL and large-scale transactional or operational datasets
• Exceptional written and verbal communication, including the ability to write crisp API and product documentation
• Experience in travel commerce (lodging, cars, flights) or adjacent industries such as fintech, ads, or marketplace infrastructure
• Background in connectivity, distribution, or supplier technology (GDS, channel managers, OTA APIs)
• Prior experience in Engineering, Data Science, or a technical role
• Familiarity with auction or deduplication mechanics, dynamic pricing systems, or recommendation and ranking models
