Some work may involve the k6 cloud offering, which builds on top of k6 to run distributed tests across data centers worldwide.
Work alongside experienced engineers in an environment that values clarity, pragmatism, and sound engineering judgment.
Engineers are expected to understand the constraints, propose a pragmatic design, and carry the work through to delivery.
Focus on small, safe, incremental changes between releases.
