The position

Job description

Captain Data builds API-first products for SaaS companies and AI agents that sell go-to-market, sales intelligence, and outbound automation solutions.

Our APIs are embedded into products such as outbound platforms, enrichment tools, and AI-driven GTM systems.

Our platform is used directly by developers and product teams to build core features on top of our APIs — which makes product clarity, activation, and developer experience absolutely critical.

We’re now looking for a Senior Product Manager who can own product discovery, activation, and delivery for complex, API-driven products, and help push them to the next level.

The Role

This role is not an entry point into Product Management — we’re looking for someone who can take ownership quickly and raise the bar.

This is a product-first role, with a strong API and developer experience dimension.

You’ll own the full product lifecycle: from understanding customer problems and business cases, to defining product specs, shipping features, and driving adoption.

You must be comfortable reasoning about APIs, understanding how customers integrate them, and designing products that are simple to use, adopt, and scale.

This role has a direct impact on revenue, activation, and customer success.

What you’ll be doing 🚀

  • Owning product discovery and definition for new features and improvements

  • Testing APIs, reproducing customer use cases, and building small flows to validate assumptions

  • Writing clear PRDs focused on user problems, use cases, and outcomes

  • Translating customer needs into simple, usable API product flows

  • Working closely with engineering to ensure feasibility and smooth delivery

  • Driving product activation: helping customers understand how and why to use our APIs

  • Shaping and improving developer experience (DX): concepts, documentation, examples, onboarding

  • Validating features with customers before and after release

  • Managing releases, testing, and iteration cycles

  • Partnering with Sales & CS to understand real-world usage and unblock adoption

Why is this role special

  • You’ll have real ownership over a core product

  • You’ll shape how hundreds of SaaS companies integrate and build features

  • Your work will directly impact activation, revenue, and product perception

  • You’ll operate in a small team where product decisions matter a lot
