We are seeking a Senior Backend Engineer (Go) to drive the evolution of the authorization platform. In this role, you will own the design and implementation of critical backend components, working with existing microservices written in Go and Java to deliver new functionality, migrate legacy code, and optimize performance. You will collaborate closely with product managers, frontend engineers, QA, and R&D teams to translate customer requirements into production-ready, scalable solutions. Given the platform’s complexity, high release cadence, and cloud-native foundation, you are expected to onboard quickly, work autonomously, and leverage AI-assisted development tools to increase delivery speed and quality. Your work will directly impact platform scalability, security posture, and customer satisfaction.

About the Product

Our product is a modern authorization platform that centralizes policy management and enforces dynamic, real-time access control across applications, APIs, and data. It combines centralized policy definitions with decentralized enforcement points to deliver low-latency authorization at scale. The platform integrates with leading IAM providers such as SailPoint, Okta, and Azure AD, and supports PostgreSQL, Elasticsearch, and MongoDB as backend data stores. Serving 100+ enterprise customers across finance, healthcare, and other regulated industries, the system processes millions of authorization requests per day, solving the industry challenge of fragmented and static access control. Reliability, security, and performance are critical in this high-volume, data-intensive, multi-tenant environment.
