API Integration Specialist

About Pylon

The $13 trillion mortgage industry at the core of the American economy runs on broken assembly lines with human-powered workflows, stitched-together software, and a series of capital markets intermediates. The costs to originate are at an all time high despite foundational shifts in technology.

Pylon is rewiring mortgages from the ground up. We are building the only API-first, programmatic infrastructure that fully automates credit, compliance, capital, and operations. For the first time, originators can build and scale mortgage businesses entirely through software, not people. Our team comes from Stripe, Better, and Affirm, and we are backed by Conversion Capital, QED, Citi, Fifth Wall, Peter Thiel, and the founders of Ramp, Mercury, Blend, and others.

About the role

We're looking for an API Integration Specialist to join our product team and lead client onboarding, from the first integration conversations to post-launch success. You'll work directly with fintechs, brokers, and lenders as they embed Pylon into their product flows using our APIs, Command Center (loan officer dashboard), and out-of-the-box Elements components (borrower loan application and borrower dashboard).

Your role is deeply cross-functional. You'll work hand-in-hand with product managers, forward-deployed engineers, and account managers to ensure clients go live quickly, integrate intelligently, and build toward long-term success. You'll also bring structured thinking to our onboarding and support processes, helping create repeatable systems that scale.

If you're energized by the challenge of supporting deeply technical products, navigating regulated environments, and launching real production workflows that touch consumers and capital markets—you'll thrive here.

You are expected to

• Own the end-to-end onboarding process for new customers: from kickoff and integration design through launch and post-go-live support

• Help customers think through how to integrate our API and Elements (our embeddable UI toolkit) into their workflows and user experience

• Build and maintain a repeatable onboarding and scoping framework that allows us to support customers efficiently and consistently

• Work closely with account management to align on joint success plans, customer KPIs, and timelines

• Provide post-launch support to ensure continued success, including triaging issues and routing product feedback

• Work with product/engineering to forward deploy customer integrations, influence roadmaps and help scope feature requests

• Maintain deep product expertise and act as a consultative voice to help clients get the most out of Pylon

About You

• You have a strong technical foundation and know how a platform product works - APIs, UI components, backend services

• You're a structured communicator who brings clarity to complex projects, internally and with customers

• You love working cross-functionally and know how to build strong partnerships with product, engineering, and GTM teams

• You're energized by customers and thrive in live settings like working sessions, integration calls, or go-live check-ins

• You enjoy working in zero-to-one environments and want to help build the playbook, not just follow it

Requirements

• 4+ years of experience in implementation, solutions engineering, technical account management, or technical product roles

• Experience working with or integrating APIs and understanding developer workflows

• Strong project management and problem-solving skills

• Excellent written and verbal communication skills

• Ability to manage complex, multi-stakeholder projects across technical and non-technical counterparts

• Experience in fintech, SaaS, or infrastructure products preferred

Must live in or be willing to relocate to the Bay Area (CA) or New York City.
