Testing in IoT energy software. Real product, mentor from day one.

Our software manages energy in buildings and factories around the world. FLOWBOX has been on the market since 2012 and this year we partnered with Eaton – we're building Flowbox 2.0.

QA coverage is growing and we need someone to strengthen the team. This is a role for a student or junior who wants to learn how to test properly – from day one, with a real product and a mentor by your side.

The team is led by CTO Juraj Longauer. We work in Claude Code, YouTrack, GitLab, communicate via Slack and use AI tools from day one.

What you'll be doing?

• Writing and maintaining automated tests (Selenium, Python, REST API) – with a mentor, not alone.
• Manual testing of new features and reporting bugs in YouTrack.
• Regression coverage – making sure things don't break when we add new ones.
• Working with AI tools (Claude Code) from day one.

What you'll need?

• Basics of Python or another scripting language.
• Technical mindset – you're comfortable with the terminal, REST APIs or Git.
• Interest in testing and automation.
• Communicative English (the team is Czech/Slovak speaking, Czech is a plus).

Nice to have?

• Knowledge of Selenium or Playwright (even from a course or side project).
• Experience with Git.
• Eagerness to learn – mentoring is part of the job here, not an exception.

What we'll help you with?

• How the FLOWBOX system and energy management ecosystem works.
• Testing processes and tools in real practice.
• Writing your first tests – you won't be on your own.

What we offer?

• Work on a real product – an IoT platform with hardware, real-time data and enterprise clients.
• DPP or freelance contract, 4 hours per week to start – flexible for students.
• Start ASAP. ‍
• Multisport card – partially covered. ‍
• Education budget (events, courses, webinars) and English lessons. ‍
• Team events that are optional. We've been to the mountains, rafted the Berounka river, we cook together regularly, have company breakfasts, laser tag or paintball. ‍
• We have TACO – we send each other recognition and collect it in our company e-shop, where you'll find cinema tickets, a day off or hardware of your choice.
• Friendly environment and experienced colleagues who are happy to share know-how.
• Access to Claude from day one – we use AI tools where they make sense.
