About Similarweb

Similarweb is the leading digital intelligence platform that helps thousands of companies understand, track, and grow their digital business. Brands like Google, eBay, Adidas and many more rely on Similarweb to make smarter decisions using web and app analytics, generative AI insights, and market intelligence data. We are publicly traded on the New York Stock Exchange and still operate with the energy and ownership mindset of a startup.

We are now entering a pivotal phase in how we deliver our data. Our goal is simple and bold: make Similarweb’s data delivery AI first, so both humans and AI agents can tap into our intelligence in the most natural and powerful way.

Why is this role so important at Similarweb

As Senior Product Manager, API, you will own the products that power how customers and AI applications access Similarweb data: our REST APIs, Batch APIs and our new MCP Server for AI agents.

You will be responsible for shaping the strategy, execution, and developer experience across these surfaces. Your work will define how data driven teams, partners, and AI agents discover, query and operationalize Similarweb’s digital intelligence at scale.

This is a highly visible and strategic role at the intersection of product, engineering, data and our global customer base.

About the team

You will join our AI & Data as a Service group, the team that owns Similarweb’s external data delivery. We operate like a startup inside a public company: fast paced, highly collaborative, and obsessed with impact.

You will partner closely with:

• Backend and data engineering teams who build and scale our APIs
• AI and data science teams who use MCP and APIs to power agentic workflows
• Sales, Solutions, and Customer Success who bring customer needs and use cases

Together, you will turn Similarweb’s unique dataset into an essential data layer for both customers and AI ecosystems.

• Position Similarweb as the data layer for AI driven growth, with APIs and MCP that serve both human developers and AI agents
• Identify high value AI and agentic use cases and translate them into concrete API and MCP capabilities
• Define success metrics for AI ready data delivery, such as relevance, reliability, latency and developer adoption

Own data delivery architecture for REST, Batch and MCP

• Drive the end to end lifecycle for our APIs and MCP: design, discovery, launch, iteration and deprecation
• Partner with engineering to design scalable, secure and reliable APIs, including rate limiting, pagination, authentication and versioning
• Shape our Batch API and data feeds to support large extractions, multi year history and delivery into environments like S3, Snowflake and GCS
• Ensure our schemas are LLM ready and semantically clear so AI agents can consume them with minimal post processing

Champion developer experience and ecosystem

• Own the external developer experience for our APIs and MCP, from first page view to first successful call to production usage
• Work with technical writers and engineers to deliver world class documentation, SDKs, examples, and reference architectures
• Identify and remove friction in onboarding and integration using metrics like time to first call, activation rate and developer NPS
• Partner with Marketing and Developer Relations to build a vibrant ecosystem of partners, integrators and internal champions

Drive execution and cross functional alignment

• Translate the strategy into clear requirements, user stories and acceptance criteria for new endpoints, datasets and API capabilities
• Prioritize the roadmap based on impact, effort, risk and strategic value, keeping stakeholders aligned and informed
• Work closely with Sales, Pre sales and Customer Success to support strategic deals and key integrations
• Ensure APIs and MCP comply with legal, privacy and security requirements while still being developer friendly

Connect product decisions to business impact

• Define and track KPIs such as API usage growth, credit consumption, retention of API first customers and revenue from API offerings
• Partner with commercial teams on pricing and packaging for API and MCP products, including credit models and tiers
• Use usage data and customer feedback to validate hypotheses, adjust strategy and decide where to invest next

This is the perfect job for someone who

Must haves

• 5+ years of product management experience, including meaningful ownership of client facing APIs for external developers
• Proven track record of shipping and growing developer facing products, with measurable impact on adoption, usage and retention
• Strong technical understanding of API design and architecture: REST, HTTP, authentication, versioning, rate limiting, and data modeling
• Experience working closely with backend engineers and data teams, comfortable discussing trade offs around scalability, performance and reliability
• Demonstrated ability to own a product roadmap end to end, from discovery and strategy to delivery and iteration, in a SaaS or data platform environment
• Excellent communication skills in English, capable of explaining technical concepts to non technical stakeholders and translating business needs into technical requirements
• Deep empathy for developers and technical customers, including experience gathering their feedback and turning it into product improvements

It is a plus if you have

• Experience with data platforms, analytics products, or Data as a Service offerings, especially at scale
• Hands on experience working with APIs as a user, using tools like Postman, curl or custom scripts to explore and validate endpoints
• Familiarity with cloud data integrations such as AWS S3, Snowflake, and similar data sharing mechanisms

Big advantages

• Background working on AI or ML powered products where APIs served as core building blocks
• Experience designing APIs and schemas specifically for LLM or agentic consumption, including concepts like RAG, vector search, and evaluation of AI powered experiences

And if you have any of these, boom

• Experience with Model Context Protocol (MCP) or similar standards for connecting AI agents to tools and data
• Deep familiarity with developer experience best practices, developer portals, SDK ecosystems and metrics such as time to integration and developer NPS
• Prior experience as a software engineer or writing production code, especially in backend or data engineering environments
• Exposure to SEO, digital marketing, competitive intelligence, or adjacent domains where Similarweb data is heavily used
