The opportunity
AI needs a new infrastructure layer. We're building it at Modal.
What you'll do
Design and improve isolation mechanisms for multi-tenant workloads: (containers, sandboxing, execution environments)
Strengthen boundaries between customers, workloads, and internal systems
Identify and mitigate risks in distributed, dynamic compute environments
Secure and harden containerized workloads and orchestration systems (e.g., Kubernetes or similar)
Improve workload isolation, scheduling boundaries, and runtime protections
Evaluate tradeoffs in multi-tenant execution models
What they're looking for
- Design and improve authentication and authorization systems across services
- Implement strong service-to-service identity and least-privilege access patterns
- Improve access controls across infrastructure and internal systems
- Build and maintain systems for securely managing secrets, tokens, and credentials
