Principal Backend Software Engineer
About the Role
As a Principal Software Engineer at Radiant, you’ll be a hands-on technical leader, driving the design and development of our most critical systems, including our GPU orchestration layer, inference-serving infrastructure, and core platform APIs.
You’ll set the standard for engineering excellence across the team, working closely with other principal engineers to align on strategy and drive technical leadership. You’ll partner with peers in infrastructure and machine learning to deliver high-performance AI systems, and mentor engineers across multiple squads. While you won’t have direct reports, you’ll play a pivotal role in shaping engineering direction, design decisions, and cross-team collaboration.
What You’ll Do:
Design and develop core services for the Radiant AI Cloud
Architect and build core backend services in Go that power AI infrastructure, networking, inference orchestration, and model lifecycle management
Lead engineering design efforts across the backend domain - architecture reviews, and system evolution strategies
Collaborate closely with platform and infrastructure to deliver reliable, secure, production-grade services
