Senior QA Automation Engineer with Python + Networking

Project Description: Product verification & testing for an L1-L3 Traffic Generator Solution for a Global Networking Testing and Validation equipment provider.

Our team: A team of networking enthusiasts willing to contribute to customer success.

Technologies used: Networking protocols, traffic generation tools, Windows/Linux servers, network virtualization, network management tools, microservices.

Opportunities: Networking and testing certifications, collaboration with an international team of professionals, working with the latest networking technologies and concepts, access to training.

Responsibilities

o Design, implement and maintain long-running automated test scenarios (soak tests spanning days/weeks) using Spirent TestCenter APIs, covering performance, scalability, convergence, and protocol stability under sustained traffic load.

o Derive automation requirements from manual functional test specifications and hardware validation reports

o Collaborate with development team to translate software requirements into high-quality test automation suites

o Develop automation for the end-to-end solution validation and integrate the automation for seamless validation.

o Implement, execute and debug Python automated test scripts on Linux-based platforms

o Analyze and manage automated regression test execution failures

o Debug and troubleshoot complex issues and work closely with the engineering team on the failures and validate the fixes

o Integrate test suites into CI/CD pipelines

o Collaborate closely with hardware and software development teams to triage test failures and drive quality improvements

o Reproduce and root-cause hardware/firmware defects through systematic test isolation

o Make use of AI tooling (e.g. Claude Code, agentic AI) given customer-specific heavy usage patterns.

o Review customer deployments and customer-found issues and address any gaps in the test coverage.

Qualifications

o Overall QA background of 6+ years, with 4+ years in testing networking domain-related applications.

o QA Automation experience in an Agile/SCRUM team, focused on API and/or CLI testing (4+ years);

Python strongly preferred (other comparable languages considered).

o Automated Testing for API or CLI 4+ years, including experience in test harness or framework

development.

o Hands-on experience automating Spirent TestCenter (STC) using its Python API — specifically StcPython

native API, the REST-based stcrestclient library (py-stcrestclient), or HLTAPI (High Level Test API); ability

to script traffic port configuration, device emulation, traffic stream setup, result subscription and statistics

retrieval.

o Familiarity with STC Lab Server architecture: connecting to chassis, managing test sessions, and

executing automated sequences without GUI dependency.

o Experience writing and maintaining long-running automation suites (soak tests of days/weeks duration)

with robust result collection, error handling, and reporting.

o Working knowledge of L2/L3 protocols exercised through STC: Ethernet, VLAN/QinQ, BGP (v4/v6),

OSPF (v2/v3), IS-IS, MPLS/LDP, BFD, and data-center protocols such as VXLAN and EVPN; ability to

configure emulated/simulated router topologies for scale and convergence testing.

o Familiarity with RFC 2544 / RFC 2889 benchmarking methodology for throughput, latency, frame loss and

back-to-back testing.

o Practical experience with AI tooling in day-to-day activities to improve productivity and delivery quality

(code generation, code review, automation, agentic AI, MCP usage, etc.).

o Experience in performance, scale, and convergence testing; ability to analyze and improve performance

and convergence at system level.

o Ability to develop and publish solution validation documents and test reports.

o Strong verbal and written communication skills; able to communicate effectively across QA and

Development teams.

o Highly motivated, self-driven, and able to collaborate cross-functionally to meet challenging goals.
