Senior Mesh Network and MAC Engineer (All Genders)

Responsibilities

• Architect and implement MAC protocols and routing algorithms tailored for directional multi-node systems, directly tackling the challenge of neighbour discovery under highly focused, narrow beams.
• Build dynamic TDMA schedules and beam coordination mechanisms in lockstep with the physical layer (PHY) and antenna steering systems, ensuring routing decisions are grounded in real-time RF characteristics rather than simple hop counts.
• Deliver resilient multi-hop relay capabilities that sustain high-bandwidth video and control links between mobile platforms over tactical distances, routing back seamlessly to ground control stations under dynamic conditions.
• Build and maintain multi-node Hardware-in-the-Loop (HIL) testbeds alongside automated logging pipelines to quantitatively evaluate and verify network join times and topology reform behaviours.
• Mesh networking in a product that shipped — sim work alone does not qualify — plus Linux networking at kernel and packet level with live debugging.
• Radio-literate and has designed a medium-access scheme or TDMA schedule.

Qualifications

• You have successfully designed and shipped mesh networking protocols in commercial or defence products.
• Deep, practical familiarity with the Linux networking stack at the kernel and packet levels, coupled with strong live-debugging skills on embedded systems.
• Strong understanding of wireless propagation and physical layer realities, with hands-on experience designing medium-access control schemes or TDMA schedulers.

Nice to have

• Active contributions to open-source routing protocols (e.g., batman-adv, olsrd, Babel).
• A professional background at tactical mesh vendors (such as Silvus, Persistent Systems, TrellisWare, Saab, or Bittium).
• Experience with mmWave backhaul systems or other technologies where directional beamforming is the default mode of operation.
• Batman-adv / olsrd / Babel contributor; tactical mesh vendor background (Silvus, Persistent, TrellisWare, Saab, Bittium); mmWave backhaul — already thinks in beams.
