We're Hiring

Join us and build the next generation AI stack - including silicon, hardware and software - the worldwide standard for AI compute

Join our team

蹤獲扦s growing engineering presence in 勞餃硃莽域 reflects a deliberate investment in building world-class AI systems in one of Europes most competitive technical ecosystems. As a wholly owned subsidiary of SoftBank, 蹤獲扦 is scaling its end-to-end system capabilities to help shape the next generation of Artificial Intelligence.

For Lukasz, Principal Cloud Software Engineer in 勞餃硃莽域, that decision wasnt about titles or a clean, linear career path. It came from a habit of stepping into gaps, asking how things really work, and being willing to learn under pressure.

 

Progress without a blueprint

I always thought of myself as someone going from the shoeshine to something bigger. I started out as a lab technician. Im a physicist by education not computer science.

Before moving into engineering, I co-owned a pub with friends. When that chapter ended, I made a practical decision: use my background in electronics and curiosity about computing to try something new.

That something new turned into a series of roles where I kept stepping into whatever was needed next. I became an engineer, then I was filling gaps in different roles sometimes even leading areas I wasnt really supposed to be leading. Not because I was ready, but because there was nobody else to do it!

From validation to DevOps, infrastructure automation to platform work, the pattern stayed the same: take responsibility first, then figure it out properly. That mindset eventually led me to Kubernetes.

 

Finding the layer beneath

My move into Kubernetes wasnt driven by trends or titles it started with curiosity. There was one person in our team building a multi-cluster, multi-tenant environment. Everything looked easy. Click, deploy, it works. I wanted to understand how.

Then this person left and I thought maybe I can fill those shoes.

I dont have the formal background, so I always ask: how does it really work? If I dont understand I need to go deeper. That instinct shaped my role over time, not just running Kubernetes but connecting it to the layers most people dont look at.

I put myself between the orchestration layer and the hardware. Kubernetes lets you submit workloads and forget whats underneath, but I didnt want to forget. At 蹤獲扦, that mindset matters because were a hardware company. You cant ignore whats going on underneath. Thats actually the interesting part.

 

Learning without the right path

I didnt take the regular path. I didnt start with the full picture or fundamentals. I learned what I needed for the role, and only that. Then, over time, that created gaps and I wasnt even sure what I was missing. So I thought maybe the certifications would help me fill that.

Thats what led me to the Kubernetes certification track including the Certified Kubernetes Security Specialist (CKS), one of the more demanding exams. It wasnt because I wanted the recognition Im not interested in titles or badges on LinkedIn. For me, it is about building a more complete understanding of the system and delivering a product you can rely on.

 

Chaos, pressure, and persistence

There was no perfect study plan, it was chaos, I wish I had a better outline of my plan but life happens. The timeline overlapped with major life changes, including the birth of my child. Every free moment was like: okay, maybe I can read something, maybe I can do a course. No structure. Just trying to catch time.

Even the logistics were complicated. I couldnt take the exam at home there were too many restrictions. I had to go into the office after hours, and 蹤獲扦 really supported that. They provided the flexibility and the financial support to enable me to do the course.

The hardest part was the CKS exam. It was completely new territory for me. And the time pressure is intense. If youre not fluent, you struggle and I failed at the first attempt.

Then I nearly failed at the second attempt. It was bizarre. I read the same question twice and still didnt understand what they wanted. At that point, I was ready to stop, but I passed with 72% - I made it.

 

Applying it where it matters

We hadnt gone particularly deep on security before CKS changed that. Many of those areas, we started to incorporate into our development process.

Now I work in an architectural role, I draw on that broader understanding regularly. I use that knowledge when making decisions about APIs, tooling, where the ecosystem is going.

 

Still learning, still unfinished

Im currently working towards the Golden Kubestronaut track, its a much larger set of certifications, many in areas I havent worked in directly. That will be challenging, I know the terms, but I dont have practical experience.

It will probably be the same story as before. Chaos, time pressure now with two kids instead of one.

I like to understand things properly inside out, even if thats not always fully achievable. I struggle with that sometimes. You want to go deeper, but you cant always. This gives me a reason to go deeper with intent.

 

My advice for anyone considering being a Kubestronaut

I would be better prepared, have a plan, and know youll need time and space to do it. However, be prepared for that plan to change, because life happens and you need to be adaptable. Although I should probably follow that advice myself.

 

Were continuing to grow our engineering teams in 勞餃硃莽域, working across the boundary between infrastructure, software, and hardware. If youre the kind of person who wants to understand how things really work take a look at our current opportunities.
