There are more than 700,000 active installations of Grafana around the globe, monitoring everything from beehives to climate change in the Alps. The instantly recognizable dashboards have been spotted everywhere from a SpaceX launch and Minecraft HQ to Wimbledon and the Tour de France. Grafana Labs also helps companies including Bloomberg, JPMorgan Chase, and eBay manage their observability strategies with full-stack offerings that can be run fully managed with Grafana Cloud, or self-managed with Grafana Enterprise Stack. The Grafana stack has grown to include two other open-source projects, Grafana Loki (for logs) and Grafana Tempo (for traces)
In June 2021 Grafana Labs acquired k6 - a Stockholm-based startup behind the open-source load testing tool for engineering teams. With k6, Grafana Labs adds extensible testing to its open and composable Grafana observability stack.
At k6, we build next-generation performance testing tools for developers and DevOps engineers.
We are pushing forward the state-of-the-art in our industry, creating open-source tools that have great developer experience and enable engineers to build reliable systems. k6 is an open-source tool that we built to reinvent the engineering principles around performance testing and enable engineers to build systems that scale.
About the role:
You will be one of five developers and maintainers of k6, a modern open-source tool for performance testing, written in Go. k6 was released publicly in early 2017 and has already received over 12,500 stars on Github and has an active community of users and contributors.
You will have a lot of influence on the project road map and will work with a high degree of autonomy, building and maintaining the tool. Your responsibilities will be to both write code, extending the functionality of k6, and maintain the code base, interface with the user community (i.e. review patches :) and potentially evangelize the tool. Your main, long-term goal will be to create the best possible tool and to get as many people as possible to use it.
You may also be involved with the k6 cloud integration, a SaaS service built on top of k6. Specifically, the parts of the cloud service written in Go, that orchestrates a distributed k6 test across 17 data centers around the world.
Due to our small teams and fast development pace, you will have a substantial and immediate impact on how the end product is architected, developed, and how the engineering team operates. Most importantly, you will work with competent colleagues and will be able to expand your knowledge and skills in different directions.

Engineering foundations
An ideal senior candidate has 4+ years equivalent experience in one or more of Fleet's three engineering foundations (and interest in digging into the others). (See https://fleet-device-management.breezy.hr/p/da3e70892475 for more information on that.)
For now, let's focus on Golang:
Fleet’s server is written in Go with go-kit. Deployments range from single servers to over 100,000 clients connected to horizontally scaled Fleet servers, handling tens of thousands of requests per minute. We aim to keep Fleet’s deployment as simple as possible to ease self-hosted deployment. MySQL and Redis are used for persistence and caching.
If you think you might be a fit for our team, we would love to meet you! Please introduce yourself, tell us a little bit about your Golang experience, and let's talk!
Sincerely,
CTO Zach Wasserman (osquery) and CEO Mike McNeil (Sails.js)
