Requirements

Experience securing cloud-native infrastructure and distributed systems in production
Background in infrastructure, backend, or security engineering
Experience working in multi-tenant or high-scale environments
Strong understanding of containerization and orchestration systems (e.g., Kubernetes or similar)
Experience designing or securing isolation mechanisms in multi-tenant systems
Solid understanding of authentication, authorization, and service identity models
Experience with secrets management and secure handling of credentials
Strong foundation in networking concepts such as segmentation, service communication, and access boundaries
Builder mentality: design and implement, not just review
Pragmatic approach to security in fast-moving environments
Comfortable working closely with engineers and influencing system design

Nice to Haves

Experience with sandboxing or runtime isolation technologies (e.g., gVisor, Firecracker, seccomp, or similar)
Familiarity with kernel-level or low-level isolation primitives
Experience securing Kubernetes or similar orchestration systems in production
Background in developer infrastructure, compute platforms, or multi-tenant systems

Design and improve isolation mechanisms for multi-tenant workloads including containers, sandboxing, and execution environments
Strengthen security boundaries between customers, workloads, and internal systems
Identify and mitigate risks in distributed, dynamic compute environments
Secure and harden containerized workloads and orchestration systems like Kubernetes
Improve workload isolation, scheduling boundaries, and runtime protections
Evaluate tradeoffs in multi-tenant execution models
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
Enhance secrets rotation, auditing, and access controls to reduce secret sprawl
Secure cloud environments across providers like AWS and GCP focusing on consistency and portability
Improve network boundaries, service segmentation, and access controls
Embed security into infrastructure-as-code and deployment systems
Work closely with product and infrastructure teams to design secure systems from the ground up
Review architecture and code for security risks and provide actionable guidance
Identify patterns in risks and drive cross-cutting improvements
