Senior Networking Engineer (Rust / Systems-Level / Security)

About the Role

We’re seeking a seasoned Senior Networking Engineer to help design and implement advanced network infrastructure components focused on security, performance, and resilience. This role involves deep systems-level programming, protocol design, and secure data transport — all within a high-stakes, security-critical environment. You’ll be joining a small, fast-moving team working on ambitious next-generation networking technologies.

What You’ll Do

• Architect and implement secure network communication systems across unreliable and constrained environments
• Handle low-level packet manipulation, protocol logic, and efficient transport across custom pathways
• Write high-performance, memory-safe systems code, primarily in Rust
• Collaborate on strategies for encrypted data tunnels, connection coordination, and identity-based routing
• Work closely with security engineers to integrate cryptographic protocols and access control models
• Profile and debug complex network behaviors, bottlenecks, and cross-platform edge cases

**
What We’re Looking For**

• 5+ years of experience building low-level networked systems
• Deep understanding of TCP/UDP, transport reliability, and real-time data flow
• Experience with Rust, or advanced systems-level proficiency in C/C++ with a willingness to work in Rust
• Familiarity with Linux networking, routing, and socket programming
• Strong background in network security, including secure authentication and encryption techniques
• Comfortable with asynchronous systems, resource-constrained environments, and protocol debugging
• Self-directed, proactive, and comfortable working in a startup-style environment

**
Bonus Points For**

• Prior experience building custom network tunnels, proxy systems, or transport-layer logic
• Knowledge of NAT traversal strategies, coordination protocols, or peer-to-peer networking
• Experience working with zero-trust or identity-based access models
• Familiarity with tools like pcap, tcpdump, tshark, and traffic shaping techniques
