Polygon Labs is looking for a Senior Technical Account Manager to play a foundational role in helping enterprises integrate and scale on the Polygon Open Money Stack. You will own the technical relationship with customers from post-sale through production launch and ongoing optimization, sitting at the intersection of customer success, solutions engineering, and product infrastructure.
What You'll Do
- Lead post-sale implementation for enterprise customers, establishing integration plans, shared communication channels, and clear delivery milestones.
- Serve as the primary technical contact throughout the integration lifecycle including API onboarding, webhook configuration, sandbox testing, UAT, and production launch.
- Troubleshoot integration blockers and diagnose API or infrastructure issues, escalating to Product Engineering when deeper investigation is required.
- Run regular integration status meetings with customer engineering teams and maintain visibility across internal stakeholders.
- Create integration documentation, runbooks, and internal handoff notes that improve repeatability across implementations.
- Own the post-launch technical relationship for a portfolio of enterprise accounts across high-priority customer tiers.
- Monitor integration health, transaction activity, and platform usage to proactively identify optimization opportunities or risks.
- Conduct quarterly business reviews with technical and product leadership at customer organizations.
- Identify expansion opportunities within accounts and collaborate with Sales to advance additional use cases.
- Serve as the escalation point for complex technical issues and coordinate resolution across Support, Engineering, and Product teams.
- Investigate and resolve complex integration issues including API errors, webhook failures, transaction debugging, and edge cases across customer implementations.
- Use observability platforms such as Datadog to trace request execution paths, analyze logs, and identify root causes of production issues.
- Build and maintain a knowledge base including troubleshooting guides, diagnostic workflows, and known issue documentation.
- Triage and route technical support inquiries while ensuring timely communication with customers regarding issue resolution.
- Identify recurring support patterns and work with internal teams to develop documentation, automation, or product improvements that reduce support friction.
What We're Looking For
- 5–7 years of experience in a Technical Account Manager, Customer Engineer, Solutions Engineer, or similar role supporting enterprise customers at a payments, fintech, or financial infrastructure company.
- Direct experience working with payments APIs, financial infrastructure, or embedded finance integrations involving fund flows, settlement, or reconciliation systems.

- Experience managing technical relationships with enterprise customers, including running quarterly reviews and coordinating cross-functional resolution of technical issues.
- Proficiency using developer tooling and observability platforms such as Datadog, along with CRM or support systems such as HubSpot or Zendesk.
