API Product Manager

Role overview

VantageScore's APIs are consumed by outside developers, enterprise clients, data partners and its own internal teams. This role owns the complete developer experience across those APIs: finding them, requesting access, onboarding, testing, going to production and growing usage afterwards. It is a full-time, individual-contributor product job for someone with one to three years in product management, at least some of it spent on API products.

You will work alongside Engineering, Design, Support, Customer Success, Security, Legal/Compliance and go-to-market colleagues so that documentation is complete, self-service flows make sense, sandboxes are dependable, API behaviour is consistent and error messages tell developers what to do next. The company measures success here through less integration friction, lower long-run support cost, better adoption and retention, and higher developer and customer NPS. Expect three days a week in the South San Francisco office, so you need to live within roughly an hour of it.

What you will do

• Own the onboarding and self-serve integration path for every API consumer type, covering access requests, credentials and authentication, the first working call, testing, production readiness, launch and continued adoption.
• Set and maintain the strategy, roadmap and prioritised backlog for developer-experience and API capabilities, weighing customer value against business impact, feasibility, reliability and risk.
• Produce and keep current the API documentation set: quick starts, tutorials, code samples, reference pages, FAQs, release notes, changelogs and migration guides.
• Work with Engineering to build and run mock services, test data, API explorers, sandboxes and similar tools that let developers integrate and validate on their own.
• Define API product standards covering authentication, pagination and rate limits; resource naming and schemas; idempotency; versioning, backward compatibility and deprecation; and error responses, and get teams to follow them.
• Embed reviews of documentation, developer usability and error handling in the development and release process so consistency is checked before anything ships.
• Track the developer journey through signals such as usage, onboarding completion, error patterns, support contacts, NPS and retention, and use them to find friction and prioritise fixes.
• Mine support tickets, developer feedback, documentation search logs, usage and failure data for recurring problems that push up long-term support cost.
• Run research and usability sessions with external developers, enterprise customers, partners and internal consumers, turning what you learn into requirements, acceptance criteria and measurable outcomes.
• Coordinate launches and API changes with Sales, Marketing, Support, Customer Success, Engineering, Security and Compliance, handling release comms and migration readiness, and represent API consumers when explaining decisions, trade-offs, risks and progress to leadership.

What the employer is looking for

• One to three years of product management experience.
• Hands-on API product management: you have owned platform capabilities, integration workflows, developer-facing experiences or API products themselves.
• You have owned or improved developer onboarding, self-serve integration, API docs, sandbox or test experiences, or similar developer workflows.
• Able to turn input from customers, partners and developers into strategy, roadmaps, requirements and a prioritised delivery plan.
• Working knowledge of what keeps an API product sound over its lifecycle: versioning, backward compatibility, consistency, reliability, security, privacy and error handling.
• Strong writing and information-design skills; you can make complicated technical material clear and usable.
• Comfortable leading across functions, managing stakeholders and making decisions in an Agile setting.
• Bachelor's degree.

Good to have

• Prior work on developer portals, API docs, sandboxes or other developer-experience tooling.
• Exposure to data-provider, partner or complex B2B integrations.
• Having supported API products with a mixed audience: internal teams, data partners, enterprise customers and outside developers.
• Experience working alongside Solutions Engineering, Support, Customer Success or Product Operations.

Benefits and compensation

• 401(k) with employer match up to 7%
• Flexible time off plus 12 paid holidays
• Medical, dental, vision and wellness coverage
• Monthly team events
• Modern office and collaboration spaces
