Wireless Systems Engineer Jobs in Arizona (NOW HIRING)

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.

Work Location: This role is eligible to be based out of Axon's US hubs in Atlanta, Boston, Scottsdale (HQ), San Francisco, or Seattle, and follows a hybrid schedule. We rely on in-person collaboration and ask that team members work onsite 4 days per week, Tuesdays through Fridays, with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation. We believe that connection fuels innovation, and our in-office culture is designed to foster meaningful teamwork, mentorship, and shared success.

What You'll Do:

You will be tasked with solving the toughest wireless problems our products face: translating research into resilient, high-performance PHY/MAC systems; architecting firmware and toolchains that meet extreme latency, power, and reliability targets; and defining the wireless roadmap that balances innovation, manufacturability, and real-world performance. You will shape how our devices connect and perform at scale - from lab prototypes to deployed fleets - and your work will be judged by field performance under real conditions, not just simulations. This mission-critical wireless systems require both RF understanding and deep systems software expertise. This position sits at that boundary and defines the reliability and trust of the entire communications platform..

• 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

• 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

• 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

• 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)
