[Hiring] Technical Solutions Engineer @Polygon Labs

Role Description

As fintechs and financial institutions integrate the Polygon Open Money Stack, the quality of the integration experience increasingly shapes how quickly partners reach production. Polygon operates as a US-regulated payments platform, licensed in 48 states through 37 money transmitter licenses and 11 exemptions, and our partner base is growing.

Today, many partner integration questions are routed to Engineering. This slows product development and leads to the same questions being answered repeatedly. The Technical Solutions Engineer will own the technical experience of building on Polygon:

• API and integration documentation
• The integration path
• Technical support during the sales process
• Bringing signed partners to production

Our standard is a best-in-class developer experience in payments, where a capable developer, including one working with AI coding tools, can integrate with minimal direct support. This is a senior individual contributor role reporting to the VP, Account Management & Support.

Qualifications

• Hands-on experience with US payments, including ACH, RTP, wire transfers, card networks, or equivalent rails, and a working understanding of settlement and reconciliation.
• Experience in one of the following:
  • Leading customer API integrations from kickoff to production at a payments, fintech, or financial infrastructure company
  • Owning API documentation, SDKs, or developer support at an API-first payments company
• Strong API and troubleshooting skills, including reading logs, debugging webhooks, and reasoning through authentication and retry behavior, with tools such as Postman, Bruno, or Datadog
• Excellent technical writing, with the ability to document complex systems clearly for external developers
• Regular use of AI tools to build, document, and automate work
• Comfort operating in a fast-moving environment where the platform and documentation are actively evolving

Requirements

• Experience with stablecoins or digital assets, particularly wallets and onchain settlement
• Experience at an early-stage company, building processes or programs from the ground up
• Enough coding ability to build demo applications
• Experience with documentation platforms such as Mintlify
• Familiarity with KYB and KYC tooling

Benefits

• Cross-border payments remain slow, expensive, and opaque. Polygon is bringing regulated fiat access, wallets, and onchain settlement together into one integrated stack, and partners are building on it today.
• In this role, you’ll work closely with Product, Engineering, and Business Development leadership and set the standard for how partners integrate with Polygon.
