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/retransmissionsFragmentation / reassembly for larger packetsBasic QoS for voice, video, and file/data trafficIntegrate 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 protocolsSupport standard IP networking over the meshWork with frequency hopping and scheduling:Implement time-slot based transmission and frequency hopping patternsDesign a link-layer scheduler that respects QoS and slot timingPerformance & reliability:Measure and optimise throughput, latency, and packet loss over multi-hop linksTune parameters (MTU, retries, timers, CW, etc.) based on real-world testsCollaboration:Work closely with the hardware / SDR / FPGA team on timing, RF tuning, and integrationCoordinate with application / AI / backend teams to understand traffic patterns and QoS needsDocumentation & testing:Write clear documentation for protocols, APIs, and configurationDevelop test plans, simulation setups, and on-device tests for various topologiesMust-Have QualificationsStrong proficiency in C for systems / embedded programmingSolid understanding of computer networking fundamentals:Ethernet, ARP, IP, UDP/TCPL2 vs L3, routing vs bridging, MTU, fragmentationHands-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 similarExperience with Linux networking:Working with network interfaces, routing, bridgingUsing 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 APIsKnowledge of OFDM / COFDM, SNR, link budgets, and RF basicsExperience with frequency hopping and time-synchronised TDMA or similar schemesFamiliarity with OpenWrt or embedded Linux systemsExperience with network security / crypto, such as:WireGuard, IPsec, TLS, or custom link-layer encryptionPrior 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 layerYou’re comfortable debugging with tcpdump, Wireshark, logic analyzers, and RF toolsYou enjoy reading specs, protocol RFCs, and digging into kernel code when neededYou 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
