About the Role

Daytona is looking for a Senior System Engineer to help us build the next-generation distributed system for AI. You’ll be responsible for scaling Daytona to support millions, and eventually billions, of sandboxes running simultaneously.

This is a systems-level engineering role that requires deep expertise in distributed architectures, observability, and large-scale reliability. You’ll design and implement infrastructure that ensures Daytona runs smoothly at unprecedented scale.

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
