About the role
Responsibilities
Internal Networking & Time Synchronization
Architect, configure, and optimize the internal fault-tolerant network linking onboard compute nodes, controllers, and high-bandwidth sensors such as LiDARs and cameras.
Drive the design and reliability of vehicle-wide time synchronization using PTP and IEEE 802.1AS (gPTP) for safety-critical data paths.
Configure and troubleshoot managed automotive and industrial switches, including Marvell and Broadcom hardware.
Implement VLAN segmentation and Automotive Ethernet to ensure deterministic traffic isolation.
External Connectivity & Platform Systems
Design robust failover mechanisms and network bonding frameworks that aggregate multiple LTE/5G carriers for reliable external connectivity.
Debug and tune low-level Linux networking parameters, including NIC buffers, hardware offloads, interrupt handling, and NAPI behavior.
Write and maintain system-level software, telemetry agents, and daemons in Go and Python for x86_64 and ARM64 NVIDIA platforms.
Assist with hardware bring-up, debug PCIe and Ethernet interfaces, and integrate networking components into custom OS deployments.
Build end-to-end monitoring for the networking stack and export granular performance metrics to support fleet-scale connectivity debugging.
Requirements
Strong track record in system-level software development with deep expertise in Linux systems and networking fundamentals.
Hands-on experience with IP routing, VLANs, firewalling using nftables or iptables, and packet troubleshooting with tools such as tcpdump and Wireshark.
Solid programming experience in Go and Python.
Ability to read and understand C and C++ for lower-level debugging.
Methodical approach to debugging issues spanning user-space code, Linux kernels, drivers, and physical hardware interfaces.
On-site or hybrid work in Austin, TX is required for close collaboration with hardware and lab tools.
Nice to Have
Experience with Automotive Ethernet and Time-Sensitive Networking (TSN).
Experience implementing or debugging PTP and hardware timestamping in distributed systems.
Familiarity with serial consoles, JTAG, I2C, and SPI for isolating hardware and software faults on ARM64 platforms.
Experience with real-time Linux tuning, cgroups, CPU pinning, and scheduling priorities.
Designs, commissions, and sustains resilient operational technology infrastructure for hyperscale data centers and power facilities, spanning industrial control networks, facility systems, virtualization, and cybersecurity. Requires a technical bachelor’s degree or equivalent experience and at least five years in mission-critical controls or OT environments.
