Wireless Network Protocol Engineer
2 weeks ago
About the RoleWe 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 ResponsibilitiesDesign & 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 Integrate the radio with Linux networking: 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 Work with frequency hopping and scheduling: Implement time-slot based transmission and frequency hopping patterns Design a link-layer scheduler that respects QoS and slot timing Performance & reliability: Measure and optimise throughput, latency, and packet loss over multi-hop links Tune parameters (MTU, retries, timers, CW, etc.) based on real-world tests Collaboration: 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 Documentation & testing: Write clear documentation for protocols, APIs, and configuration Develop test plans, simulation setups, and on-device tests for various topologies Must-Have QualificationsStrong proficiency in C for systems / embedded programming Solid understanding of computer networking fundamentals : Ethernet, ARP, IP, UDP/TCP L2 vs L3, routing vs bridging, MTU, fragmentation Hands-on experience with wireless protocols at MAC / driver level , for example: Wi-Fi (802.11), 802.11s mesh, Wi-SUN, LoRa/LoRaWAN, 6LoWPAN, ZigBee, or similar Experience with Linux networking : Working with network interfaces, routing, bridging Using tools like ip, tcpdump, wireshark, tc, etc. Exposure to at least one of: Mesh / ad hoc networking (batman-adv, OLSR, Babel, 802.11s, OpenWrt) Software Defined Radio (SDR) (USRP, GNU Radio, LimeSDR, etc.) Nice-to-Have SkillsExperience writing or modifying Linux network drivers (netdev): Familiarity with ndo_start_xmit, netif_rx, SKBs, and kernel networking APIs Knowledge of OFDM / COFDM , SNR, link budgets, and RF basics Experience with frequency hopping and time-synchronised TDMA or similar schemes Familiarity with OpenWrt or embedded Linux systems Experience with network security / crypto , such as: WireGuard, IPsec, TLS, or custom link-layer encryption Prior work on MANET research (ns-3 simulations, academic projects, theses, etc.) What We’re Looking For (Mindset)You like working close to the hardware , not just at the application layer You’re comfortable debugging with tcpdump, Wireshark, logic analyzers, and RF tools You enjoy reading specs, protocol RFCs, and digging into kernel code when needed You can take a high-level “we need voice + video over a mesh in bad RF conditions” requirement and turn it into a concrete protocol and implementation plan
