5. Monitoring resources and optimizing sandbox performance, shaving off every millisecond

6. Solving general infrastructure challenges at scale

7. Working with orchestration technologies like Kubernetes or Nomad

8. Collaborating closely with Distributed Systems Engineers

• We ship fast, but don’t release junk

• We like hard work and problems. Challenges mean potential value.

• We have a long runway and can offer a competitive salary for the startup at our stage

• Work closely with other AI companies on the edge of what’s possible today
