Top Insider Advice

My top advice to someone starting is to build a strong foundation in the basics of IP networking. Spend time thoroughly understanding the fundamentals by reading and revisiting classic texts like those by Tanenbaum and Widjaja—they pay dividends throughout your career. Depending on whether you’re working in the control, data, or management plane, go deep into the details and truly understand the bits and bytes of how a feature works and the problem it is solving. Be open to taking on all kinds of work; no task is insignificant, as even seemingly small pieces often support critical components of the system. Especially in a small team, every member pulls their weight, and each contribution matters—both for the product and for your own growth.

What do you like about your job and the company?

What I value most about my job and the company is the people and the culture we’ve built together. The people here are humble, brilliant, and deeply human, which makes collaboration feel like a true superpower. There’s a strong zero-blame mindset, and teammates consistently step in to support one another without needing to be asked. The work itself is driven by freedom and trust, with no micromanagement—just the confidence to do meaningful work in our own way. Leadership leads by example rather than dictating, creating a genuine sense of work-life harmony. Adding to this is the presence of long-tenured colleagues, some with nearly 30 years here, whose wisdom and experience provide invaluable perspective and continuity.

Greatest achievements

One of my greatest career achievements has been filing my first patent, which introduced an innovative approach to scaling IP networks. Alongside this, I’ve worked on solving critical issues in multicast functionality, including the design and implementation of OISM and MLD snooping, taking these features from concept to production-ready solutions. These efforts not only addressed complex technical challenges but also improved network reliability and scalability in real-world scenarios. Over time, I’ve grown from focusing purely on implementation to owning design decisions, collaborating closely with cross-functional teams, and being trusted to work on critical networking components.

If you are seeking a career that will be memorable and impactful, sometimes you may need to step outside of your comfort zone and take a leap into unknown waters. I took the leap twice - once when changing my role function (from accounting to recruiting), and secondly, industry-wise when joining Nokia. I did not regret either of those decisions and I feel this is where I belong. Don't be afraid to pursue your passion, with dedication and consistency your career aspirations can become a reality.

Despite I've been in Nokia for two decades, I frequently find new things and opportunities to use my skills. Nokia is like an adventure, you never know what amazing tasks you find behind the next corner! Step in with an open and bold mind and see what great experiences wait for you. Also, you don't have to be an engineer to work in Nokia, as we need many types of experts to build our success.

Ask Questions!! I know this seems quite obvious, but I have been in many situations where I was in a group with colleagues, talking about a specific technical topic and using all kinds of abbreviations that I didn't know yet. I was afraid to ask, because I didn't want to seem like the dumb one. But it is not like that. All of us started somewhere and our colleagues at Nokia know that as well. If I just had asked questions right away, it would have helped me immensely.
