- Apply deep expertise in TCP, UDP, and multicast to understanding trade-offs in short-haul vs long-haul networks

- Deep attention to detail with a rigorous approach to performance troubleshooting and optimisation
- Proficiency in system-level tools (e.g., gdb, perf, tcpdump, valgrind, wireshark)
- Comfortable working autonomously and taking ownership from problem to solution
- Scripting experience (e.g., Python, Bash) and exposure to CI/CD or observability tooling is a plus
