• Kubernetes and container orchestration
• CI/CD pipeline design and automation
• Identity and access protocols (OIDC, OAuth, mTLS)
• System resilience and fault tolerance patterns
• Observability and monitoring design
• Async communication and technical leadership

Benefits

• Work on frontier agent-native infrastructure and emerging protocols
• High autonomy and opportunities for technical mastery
• Remote-friendly, distributed team environment
• Opportunity to shape company culture during 0→1 phase
• Collaborate directly with repeat founders from Snyk, Auth0, HashiCorp, and Heroku
