Job description

Your tasks

cplace is the platform for project and portfolio management that leading companies use to steer their most complex initiatives - grown in the DACH region and, with our launch in the US, on its way to becoming an international provider. As a Senior SRE in our Cloud Operations team, you will run our existing cplace Cloud 1.0 reliably and securely for customers in automotive, life sciences, manufacturing and retail - and actively shape the architecture and operating model of our Kubernetes-based cplace Cloud 2.0. AI is in cplace's DNA: we use it intensively across all our work and expect you to apply it productively and critically and to help us take it further.

• cplace Cloud 2.0: Co-building the Kubernetes platform - from cluster design, networking and storage to tenant isolation and scaling - plus planning and driving the migration of customer environments from Cloud 1.0
• Everything as code: Development of reusable Terraform modules, GitOps repositories and our own platform software (self-service portal, APIs, automation), including code reviews, automated tests and policy as code
• cplace Cloud 1.0: Operation and improvement of our environment of Linux servers, containers, SQL databases and Elasticsearch; lasting resolution of bugs, findings and capacity issues (incident and problem management, post-mortems); conversion of manual procedures into versioned, tested code (Ansible, Terraform, n8n)
• Improvement of monitoring, logging and alerting; ownership of backup & recovery, disaster recovery and business continuity, including regular testing
• Technical implementation of security and compliance requirements (e.g. SOC 2, ISO 27001, GDPR) and optimisation of cost and capacity
• Driving AI in operations, e.g. for incident and log analysis and agents for runbooks and routine tasks
• Close collaboration with product development for smooth releases, technical representation of the team in customer meetings, tenders and customer projects, and knowledge sharing through internal and external documentation and mentoring
• On-call duty in a fair rotation

What we expect

• Degree in computer science or a related STEM field, or comparable vocational training, plus several years (ideally 5+) of experience as an SRE, DevOps or platform engineer in business-critical production environments
• Solid hands-on experience with Kubernetes in production (operations, upgrades, troubleshooting, storage, networking) and with at least one cloud provider - AWS, GCP, Azure and/or Hetzner Cloud a strong plus
• Deep experience with infrastructure as code (Terraform, Ansible), CI/CD, GitOps and Git-based collaboration via pull requests and code reviews - with modular, tested code that stays maintainable for the team
• Strong Linux skills and experience with SQL databases (e.g. MariaDB), Elasticsearch/OpenSearch and observability stacks (e.g. Prometheus, Grafana, Loki/ELK)
• Solid software engineering skills, ideally in Go or Python - tools and automation with tests and clean structure rather than one-off scripts; confident Bash scripting a given
• Good understanding of cloud security (e.g. network segmentation, secrets management, WAF)
• Hands-on experience with AI tools in everyday engineering and a good sense of their strengths and limits
• Customer-focused, structured way of working, ability to explain technical topics clearly, and fluent German and English

This is what we offer

• Flexible work model and remote work option
• Room for creativity, co-designand further development
• Competitive salary, 30days vacation& sabbaticaloption
• Wellpass,jobbike&corporatebenefits
• Modern and central offices in Munich,Hannoverand Ludwigsburg
