#LI-DNI 

One of our terminal-based product teams is looking for a new junior/medior teammate!

We build end-to-end features across client, backend, and cloud, touching everything from Java/Android terminals to Svelte-based web clients and Scala services. Our product spans technologies, but our mindset stays the same: we apply core principles, not dogmas.

Whether you’re a seasoned junior or a mid-level dev, what matters the most is your technical curiosity, eagerness to learn across domains, and motivation to keep pushing the team and yourself forward.

We work hybrid, and ideally, we’d like someone who can drop by our Ostrava office at least once every two weeks. That said, flexibility is part of the deal.

WHAT WE OFFER:

• A manager-less structure. No micromanagement. No status pyramids. Everyone has a say, and it counts.
• Full-stack experience. You can shape the product from UI to backend and cloud orchestration. We’re not boxed into roles.
• A “stuff diving” mindset. We work with what’s needed, apply the right principles, and carry lessons across technologies.
• Freedom to grow. If you like exploring new things like DevOps, functional programming, frontends, whatever we’ve got space for it.
• Peer-driven culture. We build things together, review each other’s code, and hold regular knowledge-sharing sessions.

WHAT WE EXPECT FROM YOU:
Must have:

• Java proficiency, or solid experience with another OOP language and a willingness to switch
• Genuine interest in functional programming. Scala is our backend language of choice, and we’ll help you get there
• Readiness to drive things forward, whether it be through tech exploration, pair programming, or sharing your insights
• Ability to switch context and stay comfortable outside a single tech stack
• Curiosity, responsibility, and a desire to get things done, not because you’re told, but because it excites joy

Nice to have

• Experience with any functional or multi-paradigm language: Scala, JavaScript, Python, etc.
• DevOps awareness: Kubernetes, ArgoCD, Bamboo, shell scripting

If you love learning, solving real-world problems, and aren’t afraid of crossing technical boundaries, let’s talk.

We're expanding our R&D division, opening 30 positions for programmers looking to work with Cloud and AI. Join our existing 130 developers, spread across 18 teams, in a unique managerless organization that's all about individual responsibility, trust, and solving real problems (not just cranking out code).

Whether you’re a seasoned junior or a senior-level dev, what matters the most is your technical curiosity, eagerness to learn across domains, and motivation to keep pushing the team and yourself forward.

• Peer-driven culture. We build things together, review each other’s code, and hold regular knowledge-sharing sessions.

WHAT WE EXPECT FROM YOU:
Must have:

• Java proficiency, or solid experience with another OOP language and a willingness to switch
• Genuine interest in functional programming. Scala is our backend language of choice, and we’ll help you get there
