Role Summary
LabN is seeking a mid-to-senior Software / Protocol Developer to design and implement software and network protocol capabilities supporting complex environments. This role is focused on systems-level development, control-plane and data-plane technologies, and Linux networking—not application or UI development.
The ideal candidate has a strong background in networking fundamentals, protocol behavior, and performance-sensitive systems software, and is comfortable working close to the operating system and network stack.
Key Responsibilities- Design, develop, and maintain protocol implementations and systems-level software.
- Implement and extend Layer 3 routing and control-plane functionality.
- Develop high-performance code in C, C++, or Rust on Linux platforms.
- Work with network configuration and management interfaces (YANG, NETCONF, RESTCONF, gNMI).
- Analyze packet flows, protocol interactions, and system behavior to diagnose complex issues.
- Collaborate with network, systems, and platform engineers on integrated solutions.
- Contribute to design documentation, test strategies, and validation efforts.
- Participate in technical reviews and architecture discussions.
- 5–10+ years of experience in systems software, protocol development, or network engineering
- Strong proficiency in C, C++, or Rust in UNIX/Linux environments
- Hands-on experience with Layer 3 networking and IP routing, including multiple of: BGP, OSPF, MPLS, RSVP-TE
- Experience with network modeling, configuration, or telemetry interfaces, such as: YANG, NETCONF, RESTCONF, gNMI
- Deep familiarity with Linux networking internals or packet processing, including one or more of: eBPF, kernel modules, VPP, TC, nftables, Open vSwitch
- Scripting or automation experience using Python and/or Bash
- Bachelor’s degree required (computer science, engineering, or related field)
- Active clearance or ability to obtain and maintain clearance
- Experience working with routing stacks, data planes, or security frameworks, such as FRRouting, VPP, Strong Swan, libyang
- Background in performance tuning, low-latency systems, or high-throughput networking
- Experience supporting regulated environments
- Familiarity with distributed or real-time systems
