- 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 efforts.
- Implement QoS, prioritization, and congestion-control mechanisms.
- Contribute to encryption, key management, and secure boot integration.
- Define metrics and instrumentation for wireless performance 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.
