We’re looking for a System Administrator to take ownership of our server infrastructure and make sure the systems behind our growing business are stable, secure and ready to scale.

You’ll work hands-on across physical and virtual environments, storage, backups, monitoring and infrastructure security. You’ll also help define and maintain technical standards, improve infrastructure reliability and performance, and ensure our server environment can grow together with Sunly.

What you will work on 

• Configure, deploy and maintain our physical and virtual servers across Linux and Windows environments

• Manage virtualization platforms such as VMware, Hyper-V or Proxmox

• Take ownership of server architecture and help establish clear, consistent configuration standards

• Manage storage systems, keeping an eye on capacity, redundancy and performance

• Plan and maintain backup strategies together with relevant teams and regularly test that our restore procedures actually work when needed

• Deploy and maintain monitoring and alerting for servers, services and infrastructure

• Work closely with other IT teams to spot performance bottlenecks and capacity risks

• Keep our server environments secure by maintaining security baselines and addressing infrastructure vulnerabilities

• Manage server-side network configurations, including IP addressing, hostname resolution and DNS records

• Support infrastructure lifecycle management by migrating and decommissioning systems when needed

• Keep architecture diagrams, configuration documentation and runbooks clear and up to date

What describes you  

• At least 3 years of hands-on experience administering Linux and/or Windows server environments

• Experience with virtualization platforms such as VMware, Hyper-V or Proxmox, as well as backup solutions and disaster recovery

• Good working knowledge of infrastructure monitoring, performance troubleshooting and networking fundamentals, including TCP/IP, DNS, DHCP and VPN

• A structured and security-conscious approach to infrastructure management

• Curiosity and the drive to build and improve systems instead of simply keeping them running

• Genuine interest in renewable energy and eagerness to use innovation and AI in your work

It’s a plus if you also have

• Experience with network infrastructure and basic firewall administration.

• Familiarity with infrastructure-as-code or configuration management tools such as Terraform.

• Experience with cloud platforms such as Azure or AWS.

What we offer

• Support for your wellbeing, inside and outside work - a quarterly sports allowance via Stebby, comprehensive employer-provided health insurance (including dental care and specialist visits), and access to mental health counselling and coaching via siffi.com.

• Time to rest and reset - 28 working days of annual leave, counted only in working days and usable flexibly, plus additional paid days off, including health days and leave for important life events.

• Room to grow professionally - meaningful, hands-on challenges and a dedicated training budget for courses, certifications, and conferences, alongside internal learning opportunities to support your development.

• Flexible hybrid work - we work in a hybrid way, with no fixed rules on office days. You are trusted to balance remote work with time in the office, and while much can be done remotely, a lot happens in the office and being there regularly makes collaboration easier.

• Work that contributes to the energy transition - you will be part of a team building and scaling renewable energy across the region, working on services that support a more sustainable energy system.

If you are excited about contributing to the renewable energy sector, we would love to hear from you! We review applications on an ongoing basis, so we encourage you to apply as soon as possible.
