About the Job

Requirements

  • Strong software engineering fundamentals, with fluency in Python and at least one systems language such as C, C++, Go, or Rust.
  • Extensive Linux experience, including systemd services, working within the networking stack, and operating headless remote machines over SSH.
  • Deep understanding of WLAN standards, including Wi-Fi (IEEE 802.11) MAC protocols, WFA protocols, and coexistence with other wireless technologies such as Bluetooth, UWB, and cellular.
  • Familiarity with the Linux wireless userspace: cfg80211/nl80211, hostapd, wpa_supplicant, and the related drivers.
  • Experience with telemetry or data pipelines: collecting, storing, and querying operational data.
  • Solid grasp of networking fundamentals across the whole stack from drivers up through application layer.
  • Solid understanding of embedded system design principles, including memory estimation, resource allocation, power management, and performance optimization.
  • Experience building and debugging distributed or networked systems.
  • Proficiency with wireless performance analysis using tools such as Wireshark, logging frameworks, and low-level tracing.
  • Hands-on experience debugging hardware/software interactions using oscilloscopes, logic analyzers, protocol analyzers, and embedded logging tools.
  • Ability to work at the hardware/software boundary, including reading datasheets, driver source, and register maps.

Responsibilities

  • Design, implement, and maintain the wireless software running on deployed edge devices, including radio configuration and control, channel and power management, QoS policy, rate control, and device-side interfaces for remote node interrogation.
  • Own fleetwide telemetry and diagnostics by collecting, transporting, storing, and analyzing per-link statistics across hundreds of deployed nodes to enable remote diagnosis of link degradation.
  • Integrate and characterize vendor wireless chipsets, drivers, and firmware, including driver-level failure modes and engineering around vendor limitations.
  • Debug complex issues spanning radio, driver, kernel, and application layers; determine root causes and instrument systems for future diagnostics.
  • Collaborate with RF, Hardware Engineering, Embedded Software, and Backend teams to co-design interfaces, support new radio platforms, and connect wireless performance with end-to-end video quality and latency.
  • Build and maintain automation and tooling for fleet operations, including monitoring, alerting, configuration management, and targeted recovery processes.
  • Develop RF simulation and deployment planning tools for real site design, including propagation modeling, channel assignment, and capacity estimation.
  • Support field deployments through bring-up, site characterization, and post-deployment debugging, feeding insights from real-world behavior back into the design process.
  • Contribute to the wireless foundations for next-generation autonomous and robotic platforms, such as drone communications and distributed node coordination.

Desired Qualifications

  • Deep architectural understanding of LTE/5G protocol stacks (NAS, PDCP, RRC, RLC, MAC, PHY) and 3GPP specifications.
  • Familiarity with embedded interfaces such as UART, I2C, I2S, SPI, CAN, and PCIe.
  • Exposure to video pipelines, including encoder control, RTP or QUIC transport, and understanding the impact of packet loss on perceived quality.
  • Familiarity with software-defined radio, signal processing, or spectrum analysis tools.
  • Experience with time-series data infrastructure and observability tooling.
  • Previous work with field-deployed hardware, where environmental and software issues both affect reliability.
  • Understanding of QoS concepts and data path optimization algorithms.
