Senior Golang Backend Developer

Quick Facts

• Role: Golang Developer (Senior Backend)

• Focus: Identity & authorization, permission models, cloud services

• APIs: REST, GraphQL, gRPC

Description

You will develop cloud backend microservices and APIs for audiovisual conferencing solutions, with a focus on identity and access control. The initial priority is implementing permission sets, groups, and grants using SpiceDB to replace fixed organization-wide roles. You will design fine-grained authorization models, migrate customer access with zero downtime, and build event-driven services.

Responsibilities

• Design, build, and maintain backend microservices and APIs (primarily in Go)

• Implement fine-grained authorization (role-, resource-, and relationship-based) with SpiceDB

• Execute zero-downtime, verifiably equivalent migrations to the new permission model

• Build event-driven services using messaging systems (NATS, Kafka, or RabbitMQ)

• Design and maintain SQL schemas, queries, and data migrations

• Troubleshoot and improve reliability, security, and performance of production services

• Collaborate with Web, Embedded Software, QA, and Product Management teams to deliver features and resolve issues

• Participate in code reviews and document designs/processes in Confluence

Requirements

• Bachelor’s degree in Computer Science, Computer Engineering, Software Engineering, or equivalent practical experience

• 6+ years of commercial software development, including backend services and cloud infrastructure

• Proficiency in Go (Golang) and experience building microservices

• Experience designing and building APIs (GraphQL preferred; REST or gRPC also valuable)

• Experience with SpiceDB, OpenFGA, or other Zanzibar-style permission systems

• Experience designing relationship-based, hierarchical authorization models (ReBAC), including inherited and delegated access

• Experience with SQL and relational databases

• Experience working in Linux environments, including administration and shell scripting

• Hands-on use of AI agentic coding tools (e.g., Claude Code) daily, including directing agents, reviewing/validating generated code, and building reusable skills/tool integrations (MCP)

• Strong written and verbal communication skills; ability to work independently and in a team

• Experience with agile development practices

Benefits

• Work on globally used conferencing platform services with a strong focus on identity, security, and authorization

• Build modern backend solutions using microservices, event-driven architecture, and fine-grained permission models
