Connectivity Software Engineer

About the Team The Connectivity Software Engineering team is responsible for enabling seamless, secure, and high-performance wireless connectivity across OpenAI’s products. We design and optimize Bluetooth, BLE, Wi‑Fi, and emerging wireless technologies to ensure robust device pairing, network performance, and interoperability. Our work spans kernel drivers, system services, and user‑level tools, with a focus on real‑world performance, scalability, and reliability. About the Role OpenAI is seeking a Connectivity Software Engineer to design, implement, and optimize wireless connectivity features across our product ecosystem. You’ll work at the intersection of systems software, wireless standards, and hardware integration—building robust pairing and provisioning flows, debugging low‑level protocols, and driving performance under real‑world RF constraints. You will also support certification, field interoperability, and fleet‑scale connectivity infrastructure. This role is based in San Francisco, CA . We use a hybrid work model of 4 days in the office per week and offer relocation assistance to new employees. In this role, you will: Design, implement, and debug Bluetooth/BLE and Wi‑Fi features across kernel drivers, BlueZ/wpa_supplicant/hostapd, and systemd/D‑Bus services 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/cfg80212/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 You might thrive in this role if you: Have deep experience shipping wireless features on Linux‑based products Are highly proficient in C/C++ with scripting experience (Python or shell) and systems debugging (gdb, strace, logs, packet traces) Possess 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) Bring hands‑on experience with BlueZ, wpa_supplicant/hostapd, NetworkManager, and driver bring‑up on ARM64 or x86 platforms Have a 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) ranging/integration; 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 About OpenAI OpenAI is an AI research and deployment company dedicated to ensuring that general‑purpose artificial intelligence benefits all of humanity.
