- Deliver robust pairing, bonding, and provisioning flows (**GATT/GAP**, **LE Audio/LC3**, **WPA3/802.1X**, captive portals, **NAN**)
- Optimize link performance: throughput, latency, jitter, roaming, coexistence (**BT↔Wi-Fi**), and power modes (**TWT**, **WoWLAN**)
- Build reliable network management using **NetworkManager/nmcli**, **nl80211/cfg80211/mac80211**, **DNS/DHCP/mDNS**, **P2P/SoftAP**
- Instrument and analyze with packet captures and tooling (**btmon/hcidump**, **Wireshark**, **iperf**, **eBPF/perf**, spectrum sniffers)
- Drive interoperability and certification readiness (**Bluetooth SIG**, **Wi-Fi Alliance**) and resolve field issues with root-cause fixes
- Contribute to OTA-safe configuration, telemetry, and diagnostics for fleet-scale operation

## Requirements
- Deep experience shipping wireless features on **Linux**-based products
- Highly proficient in **C/C++** with scripting experience (**Python** or shell) and systems debugging (**gdb**, **strace**, logs, packet traces)
- Deep knowledge of **Bluetooth Classic/BLE** (**HCI**, **L2CAP**, **GATT/GAP**, profiles) and **Wi-Fi** (**802.11 a/b/g/n/ac/ax**, **WPA2/3**, **nl80211**, **NAN**)
- Hands-on experience with **BlueZ**, **wpa_supplicant/hostapd**, **NetworkManager**, and driver bring-up on **ARM64** or **x86** platforms
- Proven track record of improving real-world performance and reliability under RF constraints

## Preferred Qualifications
- Experience with **LE Audio (LC3)**, **BLE Mesh**, advanced roaming (**802.11k/v/r**), **QoS/WMM**, multicast/**IGMP**
- Coexistence tuning across radios (**BT/Wi-Fi/UWB/mmWave**) and antenna/RF fundamentals with test equipment workflows
- Familiarity with **UWB** (**IEEE 802.15.4z**, **FiRa**); **mmWave/Wi-Gig** (**802.11ad/ay**)
- Experience with security and provisioning at scale (**EAP-TLS**, device identity, secure boot, disk/network hardening)
- Background in building factory test, interoperability, and certification test plans; upstream/open-source contributions
