About the role

You will be a part of the k6 team that focuses on the k6 cloud, our commercial product built around the OSS k6, targeted at users wanting to run performance tests at scale. Our SaaS offering allows customers to load test their systems by running distributed load tests from 15+ regions worldwide, using hundreds of thousands of virtual users sending millions of requests per second. We ingest huge volumes of data generated by k6, which can be used to view, correlate and analyze metrics from each test.

k6 is a product used by other engineers, and as such, we are looking for people enthusiastic about building high-quality tools they would want to use themselves. 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.

The team you’ll work with is developing a greenfield product that enables k6 cloud customers to get detailed insights into how their systems perform internally while being load-tested. You will join the project in the early stages, allowing you to influence and have a strong impact on the roadmap. Your main responsibilities will be to:

• Architect, develop and operate large-scale distributed systems
• Participate in, or lead design reviews that shape the future of k6 Cloud
• Review code developed by other engineers and provide feedback to ensure best practices
• Contribute to the documentation and/or educational content
• Collaborate with other teams (k6 OSS, front-end, DevOps) on delivering cross-functional features to the cloud product 

Required skills

• Strong programming background in any of the following languages: Go, C, C++, Rust, Java, C#
• Experience with large-scale distributed systems
• Good interpersonal skills
• Good technical communication skills
• Familiarity with modern software engineering processes and practices

Not required, but great if you also have

• Experience working with Go
• Experience building event-driven systems
• Experience with distributed tracing
• Experience working with time-series data
• Experience with load/performance testing
• Experience working with other programming languages such as Python and JavaScript
• Experience with Docker, Kubernetes, AWS, Grafana/APM tools
