Lead Product Manager, API Platform

About Pylon

America’s $13T mortgage market is one of the most important financial systems in the world. It underwrites the middle class and is the mechanism through which millions of families build wealth. But while every other financial instrument has been simplified to an API call, mortgages are still assembled by hand.

We started from zero and created the first vertically integrated mortgage platform that turns origination into a single API.

Publicly traded companies and the country’s largest originators are already building on Pylon. Revenue is compounding monthly. We’re backed by Peter Thiel, Conversion Capital, QED, Citi, Fifth Wall, and the founders of Ramp, Blend, and Mercury.

Working at Pylon isn’t for those seeking comfort. The people who thrive here have high agency, strong opinions, and a track record of delivering outcomes without direction. Many of us are former founders. We move quickly, challenge each other directly, and take full ownership of results. It’s hard work, but it will be worth it.

Pylon turns mortgage origination into a single API, so the API is the product. Every loan our customers originate, every integration they build, and every agent that talks to Pylon goes through it.

We’re hiring a Lead PM to own the Pylon API. That includes the domain model, the API design, and the experience of every developer who builds on it. Our API is built on GraphQL, and the schema is where all of mortgage’s complexity has to turn into something a developer can understand in an afternoon.

You’ll be deciding how mortgage gets represented in software, for our customers and for the industry. If you get it right, building a mortgage product on Pylon should feel as easy as building payments on Stripe.

• Set the API strategy across Pylon so every product and engineering team is building toward one consistent platform, and help grow the team as it scales

• Own the roadmap and quality bar for the API. Developers are your main customers

• Own the domain model. You’ll define the core entities, relationships, and lifecycle states of a mortgage, and keep the model clean as we add products, channels, and regulations

• Lead GraphQL schema design, from types, queries, mutations, and subscriptions to pagination, errors, and naming, and set the standards other teams follow

• Run API design review so new fields and mutations stay consistent and hold up over time

• Decide how we version, deprecate, and evolve the schema so we can move quickly without breaking customers

• Own the developer experience, including docs, the API explorer, SDKs, sandboxes, webhooks, and onboarding. The number that matters most is how fast a new customer gets their first loan through

• Work with engineering on performance, reliability, auth and permissions, rate limiting, and observability

• Write and ship code yourself. You’ll commit schema and API changes alongside engineers, and build against the API so you know exactly how it feels to use

• Build compliance into the API itself, so required data, disclosures, audit trails, and permissions live in the model instead of being left to whoever integrates

• Work closely with the Agent Platform team so the API is as easy for agents to use as it is for people

• Work with GTM and Account Management to scope integrations, support deals, and make sure customers succeed

• Use AI in your day-to-day work

• You have strong opinions and you’ll defend them, including about naming, which matters more than most people think. We argue about decisions a lot here, and we’ll ask you to explain your thinking and stand behind it. We also expect you to change your mind when someone shows you you’re wrong.

• You’re ruthless about priorities. Every customer…
