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 cross-functional design reviews; document designs and guide best practices in code quality and testing.
  • Mentor teammates through reviews, pairing, and technical guidance.

Required Experience:

  • 4+ years of hands-on software development in C/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).
  • DPDK user-space application and fast-path development experience.
  • SW/HW integration and lab experience (PCIe, DMA, interrupts, counters/telemetry, bring-up).
  • Knowledge of networking protocols (Ethernet/IP/TCP/UDP), congestion/flow control, and high-rate packet processing.
  • Familiarity with CI/CD, unit/integration testing, and production observability.
  • Big advantage: Knowledge of RDMA (verbs, QPs, completion model, transport semantics) and experience building or tuning RDMA data paths.

Education

  • BsC or BSEE
  • MSc or MsEE – an advantage
