We're looking for a Support Engineer to join our support team. This isn't a classic helpdesk.
You can only close a ticket properly once you understand what's actually happening in the system and the data.

You know your way around a database, you understand how a given feature was built, and you can tell the difference between routine support and a paid service request.

You sit between the customer and the developers. When a device that collects data from a building or a production plant stops working, you pick it up, go through the logs and the data, and figure out what's going on. Depending on the situation, you either fix it yourself or hand it off to development with a clear picture of what's happening.

The team is three people right now. Michal leads support, Petr handles day-to-day customer support, and Vadym is our Linux expert. We need you as the fourth, so we finally have real backup when someone's out sick or on vacation. There's room to shape how we work.

‍

What you'll be working on

• Picking up and resolving customer requests in YouTrack, from simple questions to more complex technical issues.
• Diagnosing the problem and, where possible, fixing it on the spot – finding a workaround or reconfiguring something, not just passing it on.
• Digging into the database, SQL and NoSQL, to see what's actually happening in the data.
• Telling the difference between routine support and something extra that wasn't part of the original agreement and belongs on an invoice.
• Talking to the dev team about how a feature or integration was originally designed, and shaping the fix accordingly.
• Monitoring customer environments (CheckMK, Sentry) and catching problems before the customer reports them.
  ‍

What you need

• Linux knowledge beyond everyday admin work. You understand processes, permissions, the filesystem, services.
• A solid grasp of databases – you know the difference between SQL and NoSQL and can pull information out of both.
• Experience in technical support or IT operations. This role goes beyond L1 helpdesk, so a technical foundation is a must.
• Czech at a native or C1 level, English at a communicative level for technical conversations.
  ‍

Nice to have

• You know what JSON and XML are and how they differ – you'll run into them daily.
• An interest in energy, smart home, or IoT, and some familiarity with protocols like MQTT, Modbus, or M-Bus.
• Experience combining hardware and software.
  ‍

What we'll help you with

• How the FLOWBOX system and the wider energy management ecosystem works.
• Our internal processes, workflows, and the specifics of working with partners and customers.

‍

What do we offer?

• Hybrid at Chodov Park (metro) - 3 days in the office, the rest remote. ‍
• A real greenfield - you own the platform layer from the first commit.
• Claude Code licence from day one. AI-assisted development is first-class here, not a pilot. ‍
• Autonomy that means something - you help choose the stack you'll live in.
• Multisport card, learning budget (events, courses, webinars) and English lessons.
• Team events that aren't mandatory. We've been to the mountains, rafted down the Berounka river, cook together regularly and run company breakfasts.
• We have TACO - peer recognition with a company store: cinema tickets, a day off, or hardware of your choice
