Senior QA Software Engineer, Networking

What if your Python automation caught a critical ASIC bug before the physical silicon was even manufactured? At NVIDIA, our simulation platforms make that happen every release cycle! We are the System Ethernet QA Team at NVIDIA's R&D center, responsible for the testing and qualification of virtual networking silicon (SimX) and software-from L2 forwarding and L3 routing to overlays, QoS, and security. With SimX, developers and QA engineers get hardware-free, early access to the ASIC for better debugging.

We are looking for a Senior QA Software Engineer who combines network protocol expertise with strong Python automation skills. Does debugging a BGP EVPN route leak excite you as much as refactoring a test framework? Then we should talk!

What you'll be doing:

We don't just complete checklists; we collaborate closely with R&D to lead the quality of new features from design to deployment. In this role, we:

• Review architectural designs and requirements for new features introduced to the product

• Drive the design, development, and execution of tests across functional, performance, and security scopes as part of SW GA and update releases

• Develop Python automation suites built on clean OOP principles

• Chase down defects and validate fixes until we fully resolve the root cause

• Leverage the SimX platform to validate code and debug the ASIC long before hardware arrives

What We Need to See:

• Combined network engineering depth with thorough software habits

• 5+ years of hands-on QA or networking experience, backed by CCNP-equivalent protocol knowledge: L2 (VLAN, STP), L3 (BGP, OSPF), EVPN, VXLAN, and advanced features like PFC, ECN, RoCE, and QoS

• Production-quality Python engineering-specifically, strong OOP design and hands-on experience with Pytest

• Deep Linux proficiency (at an LPIC-1 or LPIC-2 level) to navigate system internals, analyze logs, and debug effectively

• Clear verbal and written communication, with professional proficiency in written and spoken English

• B.Sc. or or B.A. or equivalent experience in Computer Science, Electrical Engineering, or a similar background

Ways to stand out from the crowd:

• Experience with Docker and traffic generation tools (Ixia, TRex, Scapy)

• Hands-on experience integrating tests into CI/CD pipelines (Jenkins, GitLab CI)

• Working knowledge of virtualization platforms (KVM, VMware)
