Mid/Senior Network Test Automation Engineer (SD-WAN)

Get to know us better

CodiLime is a software and network engineering industry expert and the first-choice service partner for top global networking hardware providers, software providers and telecoms. We create proofs-of-concept, help our clients build new products, nurture existing ones and provide services in production environments. Our clients include both tech startups and big players in various industries and geographic locations (US, Japan, Israel, Europe).

While no longer a startup - we have 250+ people on board and have been operating since 2011 we’ve kept our people-oriented culture. Our values are simple:

• Act to deliver.
• Disrupt to grow.
• Team up to win.

The project and the team

You will join a newly formed team working for a globally recognized networking leader on their flagship SD-WAN product. The team’s mission is to keep the Routing SD-WAN area healthy through pre-commit testing: every pull request automatically triggers test suites on a large-scale CI/CD test orchestration platform, so bugs are caught before they ever reach the codebase.

Your work will revolve around developing and maintaining automated test suites for the Routing area, owning weekly regression runs, and triaging failures - from reading device and test logs, through distinguishing genuine product bugs from test-suite or environment issues, to raising well-documented defects. You will work hand in hand with the development teams to understand upcoming features and translate their use cases into test coverage.

The scale is significant: the platform executes hundreds of test suites and roughly a thousand test runs a day across pre-commit, nightly, and weekly pipelines. To keep triage fast at this scale, the workflow is supported by modern AI tooling - an AI-powered root cause analysis agent that turns hours of log digging into minutes, and collaboration bots that automatically pull the right people into dedicated spaces when a suite fails.

Technology stack:

• Python as the main automation language (pyATS and the client’s internal test framework)
• pytest
• Networking: routing protocols (BGP, OSPF), routing tables, VRFs, SD-WAN overlay (policies, IPsec tunnels)
• CI/CD: Jenkins, GitHub pull request workflows
• AI tooling: AI-assisted root cause analysis, LLM coding assistants (Codex/Copilot-class tools)
• FastAPI (REST), async, subprocessing, JSON streams, caching
• Docker, Kubernetes
• Linux

What else you should know:

• The team is being formed right now - you will help shape how it works from day one
• Support is also available from the DevOps team, as CodiLime engineers are responsible for developing and maintaining the CI/CD test orchestration platform
• You will cooperate directly with the development and test engineers in a distributed, international environment (Europe, India, US)
• AI tools are part of the daily workflow, not an afterthought

We work on multiple interesting projects at a time, so it may happen that we’ll invite you to an interview for another project if we see that your competencies and profile are well suited for it.
