Software Engineer (C, Networking)

PLVision

Що робити

✅ Design, implement, and debug networking features in DPU firmware written in C — packet pipeline, Ethernet/TCP handling, SDN policy processing, or the RDMA stack, depending on where you land
✅ Root-cause hard defects — asserts, segfaults, memory leaks, race conditions, and performance regressions — using counters, telemetry, GDB, crash dumps, and console logs, across software simulation, virtualized environments, pre-silicon emulation, and real hardware
✅ Extend the team’s Python test frameworks: write new packet-level test cases, counter-based verification, and handle topology and fixture work for Linux and Windows guests
✅ Own CI health for your area — pipeline stages, nightly, and pre-commit gates, and the container and VM images they run on
✅ Work with host-side agents and kernel drivers (Windows and Linux), where a device-side change needs a host-side counterpart

🔹 2+ years of professional systems software engineering
🔹 Strong C in an embedded, kernel, or firmware context: manual memory management, pointer-heavy packet code, concurrency, and code on a fast path that must not allocate or block
🔹 Solid networking fundamentals — Ethernet, VLAN, IPv4/IPv6, ARP/ND, ICMP, TCP/UDP, tunneling, and encapsulation — and the ability to read a packet capture and explain what is wrong with it
🔹Practical Python: able to extend an existing test framework, not just write glue scripts
🔹 Real debugging skills — GDB, log- and counter-driven diagnosis, bisecting a regression to a specific build, and reasoning about failures you cannot attach a debugger to
