Senior Software Engineer | Kubernetes Automation | EU

Cast AI is an automation platform that operates cloud-native and AI infrastructure at scale, embedding autonomous decision-making into Kubernetes and cloud environments. This Senior Software Engineer role focuses on building distributed systems that automate Kubernetes infrastructure, including node placement, workload rightsizing, and GPU capacity optimization, using Go and Kubernetes. The role is remote-first and open to candidates in specific European countries.

• Design and build distributed systems that operate Kubernetes infrastructure autonomously at scale.
• Write production Go services that interact with AWS, GCP, and Azure APIs for real-time cloud resource management.
• Own features end-to-end: from design through implementation, testing, and production rollout (most projects ship in 1-4 weeks).
• Debug complex production issues across cloud providers, Kubernetes clusters, and distributed services.
• Collaborate with product and other engineering teams to solve problems that don't have textbook solutions.
• Work with time-series data, cloud provider APIs, and Kubernetes control plane internals.
• Contribute to product direction and backlog - shape what gets built next, not just how it's built.
• Participate in on-call rotation for teams that require it.

• Strong software engineering fundamentals: you design clean abstractions, write maintainable code, and can justify your architecture choices - not just make something work.
• Production experience with Go is strongly preferred; candidates without Go should demonstrate strong systems programming skills in a comparable language.
• Understanding of Kubernetes internals – autoscaling and networking.
• You've personally driven a complex project end-to-end.
• Experience with AI coding agents and agentic development workflows.
• You've used observability tooling in production.
• CI/CD and DevOps practices experience.
• Strong English skills, both written and verbal.
• Startup mindset: adaptable, proactive, and comfortable with ambiguity.

• Competitive salary (€6,500 - €9,000 gross, depending on the level of experience)
• Enjoy a flexible, remote-first global environment.
• Collaborate with a global team of cloud experts and innovators, passionate about pushing the boundaries of Kubernetes technology.
• Equity options.
• Get quick feedback with a fast-paced workflow. Most feature projects are completed in 1 to 4 weeks.
• Spend 10% of your work time on personal projects or self-improvement.
• Learning budget for professional and personal development - including access to international conferences and courses that elevate your skills.
• Annual hackathon to spark new ideas and strengthen team bonds.
• Team-building budget and company events to connect with your colleagues.
• Equipment budget to ensure you have everything you need.
• Extra days off to help maintain a healthy work-life balance.
