Job Summary:
Parsons Corporation is seeking a Cloud Routing Software Developer to join their team, where you will work on innovative solutions at the intersection of networking, cryptography, and systems engineering. This hands-on role involves designing and supporting secure network infrastructure and directly contributes to national security efforts.
Responsibilities:
• 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
Qualifications:
Required:
• 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
Preferred:
• 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
