Radio Network Integration Engineer

About the Role

We are building a next-generation SDR-based wireless mesh network for real-time voice, video, and data in challenging environments. Our stack includes a custom PHY , frequency hopping , and multi-hop MANET routing .

We’re looking for a Wireless Network Protocol Engineer who can bridge the gap between radio hardware (SDR) and Linux networking , designing robust MAC / link-layer protocols and integrating them with mesh routing (e.G., batman-adv) .

If you enjoy making packets survive over noisy RF links, tuning protocols at MAC level, and working close to the metal, this role is for you.

Key Responsibilities

• Design & implement the radio MAC / link layer on top of our existing PHY :

Frame structure, sequence numbers, ARQ / retransmissions

Fragmentation / reassembly for larger packets

Basic QoS for voice, video, and file / data traffic

Expose the radio as a Linux network interface (netdev) (e.G., sdr0)

Make it work seamlessly with batman-adv or similar mesh / MANET protocols

Support standard IP networking over the mesh

Implement time-slot based transmission and frequency hopping patterns

Design a link-layer scheduler that respects QoS and slot timing

Measure and optimise throughput, latency, and packet loss over multi-hop links

Tune parameters (MTU, retries, timers, CW, etc.) based on real-world tests

Work closely with the hardware / SDR / FPGA team on timing, RF tuning, and integration

Coordinate with application / AI / backend teams to understand traffic patterns and QoS needs

Write clear documentation for protocols, APIs, and configuration

Develop test plans, simulation setups, and on-device tests for various topologies
