Junior DevOps Engineer (100%)

Welcome to Xelon – where technology meets innovation and customer centricity. As we continue to grow our Platform team, we are looking for a Junior DevOps Engineer to join us.

This is a role for someone at the start of their DevOps journey. You don’t need to know everything yet – what matters is solid fundamentals, genuine curiosity, and the drive to learn. You will work alongside experienced engineers, take ownership of clearly scoped tasks, and grow step by step toward operating our platform independently.

At Xelon, we deliver secure, scalable, and automated Swiss cloud infrastructure for the next generation of digital services. From IaaS to SaaS, our platform powers workloads in regulated industries like finance, insurance, and public services. Our solutions – Xelon Cloud, Xelon Secure+ and Xelon HQ – combine reliability, automation, sovereignty, and simplicity in one ecosystem.

We are on a mission to become the #1 Swiss Cloud Enabler, and we are growing a team of people who want to shape the future of cloud infrastructure and software operations.

Tasks

Your role and your responsibilities

As a Junior DevOps Engineer, you support the team in keeping our infrastructure and deployment processes reliable, scalable, and secure – always with guidance and room to learn. Your areas of contribution include:

Platform Operations & Maintenance

• Help maintain and improve our systems (patching, updates, backups, certificate management) under guidance
• Assist with deploying new services and supporting migrations to improved solutions
• Support troubleshooting and root-cause analysis across the platform

CI/CD & Deployment

• Support building and maintaining automated deployment pipelines (e.g. Bitbucket Pipelines, ArgoCD)
• Assist with rollbacks, deployment health checks, and release coordination

Infrastructure Automation

• Develop and maintain Infrastructure-as-Code components (e.g. Kubernetes, Ansible, Terraform) under guidance
• Help keep configurations consistent across dev, staging, and production

Monitoring, Logging & Observability

• Help maintain and improve observability tooling (e.g. CheckMK, Loki, Grafana, Tempo, Prometheus & Sentry)
• Contribute to dashboards and alerting that increase signal and reduce noise

Security & Compliance

• Support automated security checks in CI/CD (e.g. SAST, DAST, SCA)
• Help ensure deployments meet Xelon’s compliance and security requirements (TLS/SSL, firewalls, network policies)

Documentation & Knowledge Sharing

• Write and maintain clear, easy-to-follow technical documentation
• Share what you learn with development and operations teams

Requirements

Who you are

We are not looking for someone who already knows everything – we are looking for someone who wants to understand the technologies behind the tools, not just use them.

• You are curious and learn fast – you enjoy figuring out how things work.

• You communicate openly and ask for help or feedback early when you are stuck.
• You work in a structured, careful, and security-conscious way.
• You enjoy working as part of a team and sharing knowledge.

Must-haves

• Foundation: Completed IT apprenticeship (e.g. Informatiker/in EFZ) or comparable education, or first professional experience in IT operations / infrastructure.
• Linux: Solid Linux/Unix fundamentals – shell, processes, file systems, permissions, and remote access (SSH/RDP).
• Networking: Basic networking knowledge (IP, DHCP, DNS, gateways, firewalling).
• Scripting: First experience with scripting (Bash, with exposure to Python, PowerShell, or Golang).
• Containers: Basic understanding of containers (container vs. VM, Docker basics).
