Senior Software Engineer, Developer Tooling

About Nclusion

About the Role

What You’ll Own

• Design and maintain Nclusion's testing SDK: the shared library engineers use to write and run automated tests across the stack.
• Build and own the K6 load testing framework, enabling teams to define performance thresholds and validate them in CI before every release
• Set org-wide baseline standards: test structure, coverage expectations, and naming conventions, while giving teams flexibility to build on top of them.
• Integrate both frameworks into GitHub Actions CI/CD pipelines and keep them stable, fast, and reliable.
• Write documentation and examples that make self-service the default; work with teams directly when they need it.

What You Bring

• 7+ years of professional experience in platform engineering, developer tooling, or a related discipline
• Deep expertise designing SDKs or shared libraries that other engineers have adopted: you think carefully about API ergonomics, developer experience, and abstraction regardless of language.
• Hands-on K6 experience: you've written load test scripts with meaningful ramp strategies and SLA-tied thresholds, not just boilerplate.
• Strong CI/CD fluency: GitHub Actions pipeline design, test stability, flakiness debugging
• A developer-first mindset: the engineers using your tooling are your customers, and you design accordingly.
• The credibility and communication skills to influence engineering teams you don't manage. You can make the case for a standard without being dogmatic about it.
