Senior Software Engineer - k6 Core | USA, EST only | Remote

ABOUT THE ROLE We are seeking a highly skilled Senior Software Engineer to join our k6 Core team at Grafana Labs. As a Senior Software Engineer, you will play a critical role in building and maintaining k6, a performance testing tool for developers and QA engineers. Our team is responsible for creating a reliable and scalable product that makes performance testing practical, approachable, and useful in real-world engineering workflows. WHAT YOU'LL DO As a Senior Software Engineer, you will work on features and improvements across the k6 codebase, from initial idea through implementation and delivery. You will collaborate closely with other engineers on design, implementation, and code reviews, and are expected to deliver production-quality code, maintain existing functionality, and help keep the system reliable and maintainable over time. Your work may involve the k6 cloud offering, which builds on top of k6 to run distributed tests across data centers worldwide. You will have a high degree of independence while working with the team to understand the context, evaluate trade-offs, and choose a reasonable technical approach. You will also be responsible for working with modern AI coding assistants as part of your daily workflow, backed by a company-funded usage budget to iterate quickly without unnecessary friction. WHAT YOU'LL NEED To be successful in this role, you should have strong experience building production software in Go, or another language with good support for concurrency and parallelism. You should also have experience working on larger or long-lived codebases, and the ability to work independently on scoped problems and deliver them to completion. Clear technical communication skills, especially in code reviews and design discussions, are also essential. WHY REMOTE Grafana Labs is a 100% remote company with a global collaborative culture. We value transparency, autonomy, and trust, and believe that our remote work environment allows us to thrive in an innovation-driven environment. As a remote employee, you will have the flexibility to work from anywhere in the United States Eastern time zones, and will be part of a team that values clarity, pragmatism, and sound engineering judgment. BENEFITS We offer a competitive salary and a range of benefits, including a health plan, parental leave, and education stipend. You will also have access to the latest frontier models from OpenAI, Anthropic, and Google, and will be able to use modern AI coding assistants as part of your daily workflow, backed by a company-funded usage budget.
