About The Company
Checkmk is a full-stack IT monitoring and observability platform that gives you broad and deep visibility across your entire hybrid stack, whether it's cloud, on-premises, or a mix of both. Infrastructure, applications, and user experience, all in one platform.
We power the mission-critical IT backbone for some of the world's largest organizations who serve billions of people every day, and for them, IT availability and reliability are non-negotiable.
Our story started in 2009 as an open-source project with a clear mission: make IT monitoring faster, more robust, and more efficient. Since then, we've kept pushing at the boundaries of what next-generation monitoring could look like.
Over 5,000 customers and 300 partners across 50+ countries trust Checkmk as their standard for IT monitoring and observability.
About the Role
Your mission
Checkmk helps IT teams monitor their entire infrastructure, from servers and networks to cloud and containers. Here, a feature doesn't end at the screen. People work with our product through its UI and its APIs, and AI assistants are quickly becoming just as important. If you like thinking about a feature through from the API to the screen to what an agent can do with it, this role is for you.As a Senior Python Software Engineer (m/f/d) in one of our development teams, you'll build product features and help shape where Checkmk goes next. Here's what your journey with us could look like:
- Product features: Take features from idea to release across a Python backend with its APIs and a Vue.js/TypeScript frontend, scoping them together with Product Management.
- AI, in the product and in your workflow: Help shape what our AI assistant can do for people who run complex IT environments, and grow it into something they rely on. AI tools like Claude Code are already part of how we build software, and you'll help decide how we use them.
- Evolving the architecture: A product that has grown over many years carries decisions that made sense at the time. Help reshape large parts of the codebase where the product needs it, and plan changes that move it forward step by step without disrupting the customers who depend on it.
- Collaboration: Work closely with UX, QA, Security, Product Management and other development teams. We work in two-week sprints with dailies, retros and sprint planning, and keep improving how we work.
