Job description

We’re looking for a Systems Administrator with hands-on, commercial experience in managing production systems. Someone who’s passionate about reliability, automation, and 24/7 operations. This role combines standard Systems Administrator responsibilities with participation in a 1st-line on-call rotation, including night and public-holiday coverage as part of the team’s support schedule. Most of the time, you’ll be working on Systems Administrator responsibilities.

You’ll work with AWS-based and (rarely) on-prem environments, take part in incident handling across support lines, and help maintain highly available systems used by clients worldwide.

Responsibilities

Systems Administration

• Managing and maintaining production systems for our clients – primarily in AWS, but also in traditional on-prem environments.
• Automating daily operations and system administration tasks.
• Monitoring, analyzing, and improving performance, availability, and scalability.
• Troubleshooting incidents and problems within support lines, for systems operating 24/7.
• Supporting development teams in CI/CD pipelines and secure deployments.
• Participating in architecture design and building new services from the ground up.
• Creating and maintaining technical documentation.

1st Line & On-Call Support

• Processing and handling incoming Service Desk requests from application users across our client-deployed platforms.
• Reproducing user-reported issues, searching for root causes, and escalating when needed.
• Cooperating with the 2nd and 3rd line support teams.
• Monitoring applications and user feedback (e.g., store comments).
• Participating in shift work and on-call duties, including nights and public holidays.

Requirements

• Minimum 2 years of commercial experience in system administration (Linux or Windows Server, Windows 365).
• At least 1 year of practical experience with relational databases (PostgreSQL, MySQL, or MS SQL).
• Practical experience maintaining high-availability systems running 24/7.
• Scripting skills (Python or Bash).
• Comfortable working in English (both written and spoken).
• Availability to participate in on-call rotations and work during night hours.
• Strong communication and collaboration skills.

Nice to have

• Hands-on experience with AWS in production environments.
• Experience in similar support or Service Desk roles.
• Familiarity with video streaming/distribution workflows (OTT).
• Knowledge of containerization (especially Kubernetes).
• Networking and security background.
• Experience with Atlassian stack (Jira, Confluence).
• Knowledge of monitoring/observability tools.
• Infrastructure as Code (Terraform, Ansible, CloudFormation).
• Technical degree in computer science or related fields.

What you’ll get in return

• fully remote work with flexible working hours
• MyBenefit platform funds (that you can use to buy a MultiSport card or other cool services)
• a choice to join our group health insurance
• access the wellbeing platform Mindgram that helps you stay in a good mental shape
• access to the language learning platform Tutlo
• company-wide quarterly meetings (which are special, because you don’t have to work on that day)
• optional (bun fun!) team activities, like joint mountain trekking trips, St. Nicolas Day event for kids, board game nights, and more.
• a welcoming office in the very heart of Poznań, if you prefer to work on-site.

You can count on our feedback after each stage to ensure the process is as transparent and valuable as possible.
