Software Engineer (Go)

The Opportunity Agentero is a remote-first, Series A-backed startup building technology to modernize insurance distribution. One of our core initiatives, Producerflow (www.producerflow.com), is transforming how carriers manage producer onboarding and compliance for millions of users. With $25M+ raised from top investors including Foundation Capital (Uber, Netflix) and USV (Twitter, Coinbase). We’re at an inflection point, and we’re looking for builders to help us scale.

You’ll work closely with design and product to deliver end-to-end features, leveraging AI-assisted development to move faster and smarter.

• Design and implement reliable backend services in Go that directly solve carrier operations and developer integration challenges.
• Own API design and implementation for both internal UI consumption and external developer integrations, ensuring excellent developer experience.
• Build comprehensive testing strategies (unit, integration, E2E) to maintain 99.9% uptime and catch issues before users do.
• Implement monitoring and alerting that helps us proactively address issues before they impact carriers or developers.
• Contribute to engineering best practices and help teammates level up with AI tools.
