Principal Product Manager, HTS API Marketplace

Role overview

HTS (Hopper Technology Solutions) is the division through which airlines, banks, hotels and travel agencies plug Hopper's fintech and travel inventory into their own channels. The HTS API Marketplace will be the commercial, developer-facing front door to Hopper's lodging and car capabilities, and this Principal PM is the person who decides what it becomes. The underlying engines (connectivity orchestration, pricing and ranking, content mapping, the extranet) already have their own capability teams; your role is to work with those PMs and shape their systems into coherent, enterprise-ready API products with a pricing model, onboarding path and go-to-market plan.

This is genuinely 0-to-1. Hopper expects the hire to prototype before writing a PRD, using LLMs and vibe-coding tools to mock APIs, simulate partner portals and test pricing configurations ahead of any engineering commitment. You will work across Engineering, Data Science, Commercial, Finance and Supply, and you will own the marketplace revenue line, tracking GBV, take rate and unit economics per capability. The role is fully remote within the United States.

What you will do

• Decide what the HTS API Marketplace actually is: how a portfolio spanning HTS Connect, Search Polygons, Autocomplete, Ranking, Content & Property Mapping, Room Mapping, Deduplication/Auction, Pricing, Extranet, Taxes and the Custom Deals Engine gets grouped, bundled and priced.
• Work alongside the PMs who own each underlying system to learn their roadmaps, constraints and customisation options, then turn that knowledge into APIs external partners can consume.
• Set the commercial model for the marketplace, including platform-fee versus variable-fee choices, take-rate structure per capability, enterprise bundles, and a custom-deals framework for large partners with distinct customer segments.
• Stand up the developer and partner experience from zero: API specifications, onboarding flows, documentation conventions, sandbox environments and integration tooling that shorten time to first value.
• Prototype with AI tooling before engineering gets involved, for example mocked API responses, partner portal mock-ups, and simulated pricing and ranking configurations.
• Define the go-to-market motion with the Commercial team: match the right partners to each capability, sequence the launches, and agree what a successful rollout looks like.
• Run the marketplace P&L with Finance, modelling and tracking gross booking value, take rate and per-capability unit economics.

What the employer is looking for

• 7+ years in product management, including at least one product you took from initial concept through to commercial launch.
• Proven track record with developer-facing or B2B marketplace products, with direct ownership of API design, developer experience and enterprise packaging.
• An AI-native working style: LLMs and vibe coding are your default prototyping tools, and you have shipped working demos or proofs of concept that way before handing over to engineering.
• Solid understanding of marketplace economics, covering take rates, supply-side incentives, demand-side optimisation and the choice between platform and variable commercial models.
• Able to coordinate several product teams at once: pull roadmaps together, expose dependencies and drive alignment without owning the engineering yourself.
• Experience with external enterprise partners, turning their commercial asks into product requirements and managing expectations across phased rollouts.
• Comfortable in SQL and with large transactional or operational datasets.
• Excellent written and spoken communication, including the ability to produce crisp API and product documentation.

Good to have

• Background in travel commerce (lodging, cars, flights) or a neighbouring space such as fintech, advertising or marketplace infrastructure.
• Exposure to connectivity, distribution or supplier technology, for example GDS, channel managers or OTA APIs.
• Earlier career time in engineering, data science or another technical role.
• Familiarity with auction or deduplication mechanics, dynamic pricing, or recommendation and ranking models.

Benefits and compensation

• Competitive salary plus pre-IPO equity at a well-funded startup.
• Unlimited paid time off and a Carrot Cash travel stipend.
• On-demand co-working access through FlexDesk plus a work-from-home stipend.
• Parental leave described as well above industry norms.
• Medical, dental and vision coverage fully paid by the employer, plus disability and life insurance.
• Health Reimbursement Account, DCA/FSA and a 401(k) plan.
