Technical Product Manager III

🌐 Who We Are

Bankjoy is a Y Combinator and Bessemer Venture Partner backed FinTech startup. We are changing the way community banks and credit unions do business, enabling them to become tech-driven and digital first. Bankjoy provides modern digital banking products including mobile banking, online banking, online account opening, loan origination, and conversational AI. Our mission is to revolutionize banking tech infrastructure by leading digital transformation at financial institutions — big and small.

💼 The Role

The Vendor Integration team owns every fintech connection in our product suite. That includes payment and card vendors, identity and fraud vendors, data aggregators, and the SSO that brings third-party products seamlessly into our apps.

The team is small and generalist by design: five engineers and one QA working across the entire vendor surface. As the team's only PM, you own every PRD, every vendor decision, and every roadmap call in this space. If you want real ownership and a direct line from your decisions to production, this is the role.

🧠 What You'll Do

• Take vendors from first call to production. You'll dig into vendor API packages (Swagger specs, Postman collections, SSO and iFrame guides, certification checklists) before kickoff and find what the docs imply but don't say. You'll run the open-question list with each vendor, hold the line on scope and schedule, and own the pilot client relationship through UAT and go-live.

• Write specs engineers love to build from. You'll write clear, readable PRDs and a companion context doc covering vendor requirements, gaps, tech debt, decisions, and open questions. You'll run a readiness check before engineering starts and break epics into small, testable stories that QA can accept with confidence.

• Do your own technical diligence. You'll read our .NET backend and Angular frontend to understand how existing integrations work before anything is sized. You'll spot the surprises early, decide what can be reused, and occasionally ship a small change yourself on a branch when that's faster than writing a ticket.

• Coordinate across teams. You'll partner with the authentication team on shared SSO code, with the banking core team on the data your vendors depend on, and with core product teams (account opening, lending, PFM) who rely on the vendors you manage.

• Document what ships. You'll write product feature specs, vendor implementation guides, and client test guides so our Implementation team can roll out features without you. You'll also draft quarterly release notes for our clients and retire outdated documentation deliberately.

• Design without waiting. You'll create first-draft screens in Figma using our design system and hand them to design for review. When a flow needs to be clicked to be understood, you'll build an HTML prototype.
