Lead Security Architect – Cloud Platform & Network Security

The role

This person will spearhead the security architecture for a LEO satellite network infrastructure. They will own runtime threat resistance, zero-trust network topology, cryptographic key management, and distributed systems defense.

What you will do

• Architect and implement identity frameworks to establish cryptographically verified identity for microservices.
• Conduct threat modeling and design runtime security controls for the SDN stack.
• Deploy eBPF-based runtime monitoring and policy-as-code admission controllers.
• Design, orchestrate, and execute formal cryptographic key ceremonies.
• Oversee the architecture for root-of-trust, HSMs, TPMs, and Vault clusters.
• Collaborate to embed security observability into high-throughput logging and telemetry pipelines.
• Translate federal and defense cybersecurity mandates into technical security designs.

Required qualifications

• Bachelor’s degree in Computer Science, Cybersecurity, Computer Engineering, or equivalent practical experience.
• 10+ years in cybersecurity, software engineering, or infrastructure security.
• 5+ years architecting security for distributed cloud platform software.
• Deep understanding of Kubernetes architecture, container isolation, Linux kernel security, and eBPF technology.
• Hands-on experience with modern networking protocols, zero-trust architectures, service meshes (Istio/Cilium), and mTLS.
• Proficiency writing software or tooling in Go, Rust, or Python.
• Hands-on architectural experience with HSMs, TPMs, and enterprise secrets management (e.g., HashiCorp Vault).
• Ability and willingness to obtain and maintain a Top Secret Clearance.

Nice to have

• Experience securing carrier-grade telecom, aerospace, satellite ground stations, or critical defense network infrastructure.
• Demonstrated experience handling threat modeling (STRIDE/ATT&CK) for real-time distributed routing or control plane systems.
• Deep knowledge of public cloud security guardrails across AWS, GCP, or Azure alongside hybrid/on-prem deployments.
