Every day, they help create clarity, streamline workflows and strengthen collaboration. We build with courage, ownership and meaningful collaboration - and we stay inspired by the real impact our products create for the people at the heart of education. Our ambition is clear: to become Europe’s leading EdTech brand.

If you want to join that journey and grow with us, we would love to hear from you. Your mission

As a Senior System Engineer , you will shape how software moves from code to production across Seven Education’s product portfolio. You will own and improve the delivery experience for engineering teams by making pipelines, deployments, and release processes faster, safer, and more reliable. You will contribute to the design of shared infrastructure, observability, and build engineering standards alongside the infrastructure team. In this role, you combine deep technical expertise with informal leadership to strengthen build and delivery engineering across the group.

What you’ll do

• Own and evolve CI pipelines across multiple product lines, with a focus on reliability, speed, and maintainability
• Manage the Seven Education GitHub organization, including repository structure, access control, branching strategies, code review workflows, and secrets management
• Design, maintain, and improve application deployment tooling, including Helm charts, GitOps workflows, and deployment pipelines
• Define and refine deployment standards such as environment promotion, rollback strategies, and release processes
• Improve build performance and reduce friction in the software delivery lifecycle
• Manage container image registries and support a reliable artifact lifecycle
• Partner closely with product engineering teams to shorten feedback loops and make deployments more predictable and repeatable
• Act as a trusted technical counterpart for build and delivery topics across the organization
• Support and grow the technical capability of the build engineering team through guidance, collaboration, and shared standards
• Define infrastructure standards and patterns (networking, resource limits, namespace strategies, storage) that new and migrating products adopt as they onboard.

What you’ll bring

• Several years of experience as a Systems Engineer or in a similar role focused on software delivery, build infrastructure, or platform engineering.
• Strong hands-on experience with GitHub at organizational scale (repository management, GitHub Actions, access policies, and secrets handling) and with designing, maintaining, and optimizing CI pipelines.
• Solid understanding of the container deployment pipeline, from artifact and registry management through Kubernetes application deployment with Helm and GitOps tools (ArgoCD or Flux), including deployment strategies, rollbacks, and release promotion across environments.
• Ability to reason about latency, availability, failover, and RPO/RTO trade-offs in the context of platform reliability and continuous delivery pipelines.
• A strong understanding of the full software delivery lifecycle, including branching models, environment management, and release coordination.
• Experience with observability tooling and practices including setting up dashboards, log aggregation, alerting.
• Experience with implementing infrastructure as code using Terraform.
• Familiarity with database operations such as performance tuning, backup strategies, and high a
