SENIOR IDENTITY & AUTHORIZATION ENGINEER @ ESOLGLOBAL
esolglobal is seeking a highly skilled Senior Identity & Authorization Engineer to lead the design and implementation of a modern, Zanzibar-based authorization system. This role is central to a complex, multi-tenant B2B platform, requiring a hands-on approach to building a Go-based Authorization Service and accompanying middleware. The successful candidate will be responsible for deploying these solutions on AWS using EKS and PostgreSQL, ensuring high availability and scalability for the platform.
The position involves creating sophisticated ingestion pipelines for Kafka, SCIM, and complex organizational hierarchies. You will play a critical role in leading the migration from legacy authentication systems to a modern, externalized authorization framework. Working remotely, you must be able to overlap at least 6 hours with the US-EST timezone to effectively partner with the global team and enable long-term ownership of the security infrastructure. This is a 12-month contract opportunity for a senior-level engineer with a deep background in IAM systems.
