What You'll Be Doing
Architect and scale a distributed system capable of running billions of AI agents
Build and optimize observability stacks to monitor and maintain system health
Solve challenges in scalability, reliability, and fault tolerance
Collaborate with platform and AI engineers to design a smooth, performant runtime
Contribute to frameworks and standards for high-availability distributed systems
Continuously improve performance and efficiency of the runtime layer
You Might Be a Fit If You
Have extensive experience in distributed systems, high-availability, and scaling challenges
Are comfortable with containerization, scheduling, and orchestration at scale
Excel at debugging complex systems and building observability into everything you do
Think in terms of resilience, failure domains, and graceful degradation
Can balance moving fast with maintaining long-term system stability
Bonus Points
Experience building infrastructure at hyperscale (millions of concurrent workloads)
Familiarity with AI runtimes, orchestration platforms, or cloud-native infra
Contributions to open-source distributed systems or observability tooling
