About the role
As a Senior Software Engineer, in the Networking/Drivers team, you’ll lead design and development of low-level, high-throughput data paths and device drivers in C, work closely with silicon, firmware, and validation teams, and mentor junior engineers. You’ll own features end-to-end—from architecture to lab bring-up and performance tuning. What you’ll do:
- Lead design and implementation of
user-space and driver components
(packet I/O, control paths, performance tooling).
- Drive
SW/HW integration
and board bring-up; reproduce and root-cause complex issues across layers (driver, firmware, silicon).
- Optimize
throughput, latency, and CPU utilization
; add profiling, tracing, and automated tests to prevent regressions.
- Collaborate in
; document designs and guide best practices in code quality and testing.
Required Experience:
- 4+ years
of hands-on software development in
C
on Linux.
- Proven
experience in the networking field
(e.g., NICs, switches, packet processing, data-plane/IO stacks).
- Strong systems fundamentals: concurrency, memory management, performance profiling, and debugging (gdb, perf, ftrace, tcpdump/Wireshark).
- Excellent communication skills; ability to lead projects and collaborate across teams.
Preferred Qualifications
- Device driver
design, development, debugging, and testing experience (kernel-adjacent or user-space drivers).
-
user-space application and fast-path development experience.
Education
- BsC or BSEE
- MSc or MsEE – an advantage
