What you'll be doing:

• Investigate complex performance issues seen in real-world AI data centers.

• Design and build targeted test cases from scratch to replicate and isolate hardware and software bottlenecks.

• Write and debug diagnostic scripts (Python) to drive traffic generators (e.g., IXIA) and manipulate test environments.

• Analyse test data to uncover the root cause of hardware-level behaviours, collaborating with architects to understand micro-architectural impacts.

• Develop repeatable tests that will become part of our broader automation framework.

What we need to see:

• B.S. in Engineering/Computer Science or equivalent experience with a strong foundation in hardware-software interaction.

• 5+ years of hands-on experience validating, performance-tuning, or troubleshooting networking hardware and ASICs.

• A deep understanding of how network protocols are implemented at the hardware level (Switches, NICs).

• Demonstrated proficiency in a scripting language (Python strongly preferred) for test development and diagnostics.

• Experience with network traffic generators (e.g., IXIA, Spirent).

• A problem-solving mindset, driven by curiosity to understand how things work at a fundamental level.

Ways to stand out from the crowd:

• Expertise in stress-testing network switch ASICs and systems.

• Advanced hardware diagnostics beyond standard L2/L3 protocols.

• Familiarity with network architecture and operational challenges in large-scale data center environments.

• CCNP certification or equivalent.
