Cloud Routing Developer - Topsecret

Parsons is looking for an amazingly talented Cloud Routing Software Developer to join our team as we solve novel problems at the intersection of networking, cryptography, and systems engineering! You will design, build, and support secure network infrastructure that protects sensitive communications across distributed environments.

This is a hands-on role. You will architect solutions, write code, deploy systems, manage production infrastructure, and troubleshoot complex issues at the packet level alongside a small, high-autonomy, new product team. Your work directly contributes to matters of national security. You will help the team evolve a TRL-5 prototype system into a TRL-8 product in support of a classified customer pilot deployment.

What You’ll Be Doing

• Architect and operate encrypted overlay networks across geographically distributed cloud and on-prem infrastructure
• Implement and manage cryptographic key lifecycles - generation, distribution, rotation, and revocation
• Provision and harden Linux-based systems, automate deployments, and maintain CI/CD pipelines
• Diagnose complex network failures using packet captures, structured telemetry, and protocol-level analysis
• Build internal tooling, dashboards, and control-plane APIs for infrastructure orchestration
• Support the development and implementation of intrusion detection, fault isolation, and recovery tools and procedures

• Bachelor in Computer Science, Computer Engineering, Software Engineering, or equivalent experience
• 5+ years in network engineering, security engineering, or systems infrastructure
• Networking depth: IP routing, tunneling (WireGuard, IPsec), overlay networks, and comfort working at every layer of the OSI Model
• Systems programming: Production experience in C++ and Go; scripting fluency in Python and Bash; working knowledge of Node.js
• Linux proficiency: systemd, iptables/nftables, TUN/TAP interfaces, kernel tuning - you live in the terminal
• Applied cryptography: Hands-on with AEAD ciphers, key derivation (HKDF), public-key exchange (X25519), and TLS - not just theory
• AWS/Google Cloud operations: EC2, VPC networking, IAM, and infrastructure-as-code in a production environment
• Troubleshooting instinct: You can trace a packet through a multi-hop encrypted chain and figure out where it died - even when nothing logs an error
• Ability to manage multiple assignments in a fast-paced environment
• An active Top Secret security clearance is required for this position

What Desired Skills You’ll Bring

• Relevant certification (Security+, CCNA/CCNP, AWS SA, or similar) preferred
• Experience with QUIC, DPDK/XDP, or high-performance packet processing
• Background in privacy-enhancing technologies or traffic analysis resistance
• Contributions to open-source networking or cryptography projects
• Rust experience for performance-critical components

An active Top Secret security clearance is required for this position.
