Grafana Labs is seeking a Senior Software Engineer to join the k6 Core team. k6 is an open-source performance and reliability testing tool used by developers and QA engineers worldwide. The role involves building and maintaining k6, a Go-based performance testing platform that is part of the broader Grafana observability ecosystem.
You will work on features and improvements across the k6 codebase, from conception through implementation and delivery. Much of the work involves problems that are not fully specified upfront, requiring you to understand context, evaluate trade-offs, and select appropriate technical approaches. You'll deliver production-quality code, maintain existing functionality, and ensure system reliability and maintainability.
The role includes potential work on k6 Cloud, which enables distributed testing across global data centers. This involves Go services requiring careful attention to performance, correctness, and failure handling.
You will work with high independence while collaborating closely with other engineers on design, implementation, and code reviews. The team is small, so your work has direct, visible impact on the product and its users. The engineering culture emphasizes clarity, pragmatism, and sound judgment.
Grafana Labs is a 100% remote company with 1,600+ team members across 40+ countries, backed by leading investors including Sequoia Capital and Lightspeed Venture Partners. The company serves 7,000+ customers including Anthropic, Bloomberg, NVIDIA, Microsoft, and Salesforce.
The team works asynchronously by default, with decisions captured in pull requests and design notes. Meetings focus on alignment rather than status updates. Code reviews emphasize correctness, long-term maintainability, and user impact. The company supports modern AI coding assistants with company-funded budgets and access to frontier models from OpenAI, Anthropic, and Google.
