Staff Wireless Software Engineer

We are developing the next generation of mission-critical communications systems to builds mission-critical devices used by public-safety professionals worldwide. As a Staff Wireless Software Engineer, you will be a technical leader driving architecture and implementation of wireless protocol stacks, transport abstraction layers, and real-time communication systems across our devices. You will operate at the intersection of RF, embedded systems, and cloud-connected software. This is a hands-on technical role with broad architectural influence.

Responsibilities

Lead design and implementation of wireless communication stacks (LTE, 5G, Wi-Fi, sidelink, mesh, P2P, WiFi, Bluetooth, NFC....); Architect low-latency, high-reliability PTT and real-time voice transport systems; Develop transport abstraction layers across multiple radios and networks; Optimize performance (latency, jitter, packet loss, handover behavior); Collaborate with RF, hardware, and firmware teams to ensure end-to-end system performance; Drive modem integration (e.g., Qualcomm, MediaTek) and carrier certification efforts; Implement QoS, prioritization, and congestion control mechanisms; Contribute to secure communication layers (encryption, key management, secure boot integration); Define metrics and instrumentation for wireless performance at scale; Mentor engineers and set technical direction across projects

Requirements

10+ years experience in wireless software development; Strong C/C++ experience in embedded or systems environments; Deep understanding of wireless protocols (LTE, 5G NR, Wi-Fi, Bluetooth, sidelink, or mesh); Experience working with modem vendors (e.g., Qualcomm SDKs); Experience with real-time systems and low-latency audio transport; Strong networking fundamentals (TCP/IP, UDP, RTP, QUIC, QoS); Familiarity with RF performance constraints (RSSI, SINR, handovers, link budgets); Experience debugging packet-level and radio-layer issues

Nice to have

Experience with mission-critical communications (LMR, MCPTT, public safety); Experience with 3GPP standards (Rel 16+); Experience with 5G sidelink (PC5) or device-to-device protocols; Experience implementing mesh or MANET routing; Knowledge of secure communications (AES, TLS, PKI, FIPS environments); Familiarity with Android/Linux device platforms; Experience with satellite backhaul or hybrid transport systems

Benefits

Competitive salary and 401k with employer match; Discretionary paid time off; Paid parental leave for all; Medical, Dental, Vision plans; Fitness Programs; Emotional & Mental Wellness support; Learning & Development programs; Employee Resource Groups (ERGs); snacks in our offices
