Responsibilities
- Lead the design and implementation of wireless communication stacks across LTE, 5G, Wi-Fi, sidelink, mesh, peer-to-peer, Bluetooth, and NFC.
- Architect low-latency, high-reliability push-to-talk and real-time voice transport systems.
- Develop transport abstraction layers across multiple radios and networks.
- Optimize latency, jitter, packet loss, handover behavior, and overall wireless performance.
- Collaborate with RF, hardware, and firmware teams on end-to-end system performance.
- Drive modem integration with vendors such as Qualcomm and MediaTek and support carrier certification.
- Implement QoS, prioritization, and congestion-control mechanisms.
- Contribute to encryption, key management, and secure-boot integration.
- Define wireless performance metrics and instrumentation at scale.
- Mentor engineers and set technical direction across projects.
Requirements
- 10+ years of wireless software development experience.
- Strong C/C++ experience in embedded or systems environments.
- Deep understanding of LTE, 5G NR, Wi-Fi, Bluetooth, sidelink, or mesh protocols.
- Experience working with modem vendors and Qualcomm SDKs.
- Experience with real-time systems and low-latency audio transport.
- Strong networking fundamentals including TCP/IP, UDP, RTP, QUIC, and QoS.
- Familiarity with RF performance constraints such as RSSI, SINR, handovers, and link budgets.
- Experience debugging packet-level and radio-layer issues.
- Preferred experience with mission-critical communications such as LMR, MCPTT, or public safety systems.
- Preferred experience with 3GPP standards, 5G sidelink or PC5, mesh or MANET routing, secure communications, Android/Linux device platforms, and satellite backhaul or hybrid transport systems.
Benefits
- Hybrid schedule based in Atlanta, Boston, Scottsdale, San Francisco, or Seattle, with onsite work four days per week Tuesday through Friday and remote work on Mondays.
- Competitive salary and 401k with employer match.
- Discretionary paid time off and paid parental leave.
