polygon-labs - Technical Solutions Engineer
Requirements
• Hands-on experience with US payments, including ACH, RTP, wire transfers, card networks, or equivalent rails, and a working understanding of settlement and reconciliation. • 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 • 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
Responsibilities
• API and integration documentation: Own the accuracy, completeness, and clarity of Polygon’s API and integration documentation, and keep it current as the platform evolves. • Self-serve integration: Build quickstarts, sample code, and reference architectures that enable developers, including those using AI coding tools, to integrate independently. • Technical expertise: Serve as the primary technical resource in sales conversations alongside Business Development and throughout partner integrations, then document solutions so they’re reusable. • Partner go-live: Lead signed partners through requirements intake, provisioning following KYB and KYC approval, sandbox testing, webhook configuration, and go-live validation, in partnership with Integration Delivery. • Platform knowledge: Develop deep expertise across ramps and bank rails, wallets and accounts, custodial and non-custodial flows, virtual accounts, deposit addresses, cross-chain movement, and webhooks. • Demos and enablement: Build sample applications and demo environments that support Business Development and Sales. • Product feedback: Identify gaps in the API and integration experience, and turn them into clear, prioritized recommendations for Product and Engineering. • Automation: Use AI and internal tooling to streamline onboarding, provisioning, and frontline support.
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.
