Senior Network Systems Developer (C / Rust / OpenFlow)

Full-time

Description

We are seeking a highly skilled network systems developer to help build next-generation software-defined networking technology used in industrial and operational technology (OT) environments .

This role involves developing low-level network control software , interacting directly with switches, controllers, and packet processing frameworks.

Responsibilities

• Design and implement SDN control and data-plane software
• Develop high-performance networking services in C and Rust
• Implement and extend OpenFlow-based control systems
• Build software that interacts with switch ASICs, flow tables, and packet pipelines
• Develop packet inspection and protocol analysis capabilities
• Optimize network performance, latency, and deterministic behavior
• Work closely with cybersecurity and OT networking teams to implement deterministic network policy enforcement

Requirements

Required Skills

• Strong development experience in C and/or Rust
• Deep knowledge of network protocols and packet processing
• Experience with OpenFlow or SDN controller architectures
• Experience with switch-level networking or programmable pipelines
• Understanding of TCP/IP, L2/L3 switching, VLANs, routing, and flow control
• Familiarity with Linux or BSD networking stacks
• Experience debugging packet flows using tools such as tcpdump, Wireshark, or similar

Preferred Experience

• Development involving programmable switches (P4, eBPF, DPDK, or similar frameworks)
• Experience with industrial networking or OT environments
• Knowledge of deterministic networking, time-sensitive networking (TSN), or PTP
• Experience building SDN controllers or network policy engines
• Familiarity with cybersecurity controls for industrial networks

Ideal Candidate

You enjoy working close to the network stack and solving problems involving packet behavior, deterministic control, and switch-level logic . This role is ideal for engineers who like building systems where software directly controls how networks behave .
