System Engineer | Web Hosting | Based in Lithuania

We’re looking for a System Engineer to help us solve real engineering challenges, keep our systems reliable, and build the foundation that powers millions of websites around the world. You’ll work alongside other system, software, and network engineers - people who care deeply about performance, simplicity, and resilience. Together, you’ll design, run, and evolve systems that don’t just work, but stay fast and dependable under pressure. This isn’t a role where you follow playbooks - you’ll write them. You’ll dig into the details, automate what slows us down, and share what you learn so the whole team gets stronger.

• Design, develop, and implement new features that make our hosting platform faster, more reliable, and easier to scale.
• Deploy and run infrastructure using Infrastructure as Code and automation, because manual work doesn’t scale, and neither do shortcuts.
• Operate and observe systems through real metrics: availability, latency, performance, capacity, reliability - understanding the “why” behind every graph.
• Refine and tune systems to eliminate bottlenecks, simplify complexity, and improve reliability without adding overhead.
• Improve monitoring and alerting, aiming to catch symptoms before they turn into outages.
• Share knowledge with other engineers - guiding, reviewing, and helping raise the bar for how we build and maintain reliable systems.

• Strong Linux OS experience (3+ years).
• Ansible proficiency - you trust automation, and know how to do it right.
• Programming or scripting skills in Python or Go (bonus if both).
• Experience managing and optimizing web servers, databases, and caching systems.
• Familiarity with cloud environments like GCP (or similar).
• Solid grasp of networking fundamentals - DNS, TCP/IP, HTTP.
• Experience applying Infrastructure as Code (IaC) principles and tools.

Nice to have

• Experience with DevOps practices and open-source contributions.
• Familiarity with CI/CD concepts and tools beyond GitHub Actions.
• Ability to read and understand Go and PHP code.
• Certifications like RHCSA or RHCE.

• We provide limitless learning opportunities: access to platforms like Reforge and Coach Hub, global conferences, physical and digital libraries, feedback culture, and mentoring through TesoXchange.
• Advance your career with internal mobility and grow with a team eager to share knowledge and support your success.
• Work on your terms: from modern offices in Kaunas and Vilnius, the comfort of home, or anywhere in the world.
• Enjoy flexibility in managing your schedule and bring your ideas to life in a fast-paced, dynamic environment.
• Your health comes first with insurance from Day 1, gym memberships, recharge leave, Headspace subscriptions, and regular health checks.
• Join our wellbeing-dedicated events, sports, arts, and hobby clubs, or simply enjoy the balance of a lifestyle that prioritizes wellness.
• Celebrate your achievements with company events like Summerfest & Winterfest, Town Hall, Meet the Client initiatives, team-buildings, and workations.
• Enjoy access to the Žalgiris Arena VIP Lounge and celebrate life’s big moments with milestone gifts for weddings, new parenthood, and graduations.
