Reaktor’s award-winning tech community is looking for Summer Developers to join us in Helsinki, Tampere and Turku!
If you are studying or in the early stages of your software development career and have a curious, proactive approach to problem-solving and learning, you might be just who we’re looking for.
As a Summer Developer at Reaktor, you'll be working on real projects with our clients, giving you the chance to put your knowledge into practice and gain hands-on experience in real-world development.
You won’t just be shadowing—you’ll be an integral part of the team, learning from experienced developers and contributing to meaningful work.
What we offer:
💡 Meaningful projects that solve real-life problems
You'll spend your summer programme as part of a development team, working with leading experts to build solutions that address real business or societal challenges
🤝 A passionate community of experts
As a Reaktorian, you’ll be surrounded by talented and experienced colleagues, always ready to help and share their knowledge
🏡 A workplace where you can feel at home
We’re not looking to hire your "work self" — we want you. At Reaktor, you can be your authentic self at work, just as you are at home
💰 A paid trainee period that’s more than just work
We take our work seriously, but we also make time for fun. Expect a balanced experience with regular team days and non-work-related activities
You love solving problems—not just with code, but by understanding users and designing solutions that are intuitive and impactful.
What we’re looking for:
-
You know at least one programming language/stack well
A working knowledge of multiple languages with different abstraction levels and paradigms is even better -
You’re familiar with the web stack
Frontend & backend technologies, communication protocols, relational databases—most of our projects involve web technologies, so understanding these will be a plus
-
You have experience working in a team and following good development practices
Code reviews, Git, and collaborative development—being comfortable with these will help you integrate smoothly into the team -
You can work in English and/or Finnish
Most of our projects run in one of these languages. Finnish is an advantage, but not a strict requirement -
You’re located in or able to move to Helsinki, Tampere, or Turku
You must have a valid working permit for Finland beforehand. Unfortunately, we are unable to provide relocation assistance for trainees
⚡ If you don’t check every box—don’t worry! We’re looking for potential, not just ready-made professionals.
Why join us?
For over two decades, we’ve built a culture of adaptability, innovation, and collaboration. We thrive in fast-paced environments while ensuring the well-being of our people. Join us, and be part of a company that invests in your growth, learning, and future.
While working at Reaktor, we’ll provide you with:
-
To be able to impact how you work. Together with the client, your team chooses the approach, technologies, and methodologies you think will work best in any given situation
-
A community with as much support as your heart desires
-
A team that’s not only experienced but considerate as well – they all want you to succeed
-
A sustainable work-life balance and support for your daily life outside of work. (e.g., free moving day, Reaktor car share, sick child care services, office space to use for your private events, etc.)
-
An opportunity to grow as a professional. In addition to the day-to-day work, we offer internal training courses, community events, and 15-minute coffee breaks to discuss hot topics in tech and design
-
A possibility to take part in more extended academy-like studies like Cloud Academy
-
300+ hobby clubs, from winter swimming and running to knitting and archery, that bring people together outside of (and sometimes inside) office hours. Many of these are supported by Reaktor

FAQ
01 What are we looking for?
We believe there’s more that matters than just the resume. We’re looking for an exciting overlap of curiosity, creativity, people skills, and experience: people who are willing to learn, participate, and share new perspectives.
02 What does the hiring process look like?
We take the time to learn about your skills and aspirations and help you learn about ours. Our interview process usually involves three or four conversations over the course of a few weeks. From application to closing, our process takes about four weeks. Your recruiter will keep you up to date on what to expect from each stage of our interviewing process.
03 What kinds of projects do you have?
We do a variety of different kinds of projects, with the aim of each being meaningful and critical to a client’s business. Our typical engagements are from 6 months to 18 months and involve between 3-6 Reaktorians collaborating closely with our clients. When it comes to picking and choosing, we look at a number of things from the business side. For example, we tend to be interested in the multi-functional growth potential of the project as well as the technological and digital maturity of the client, their product, and the project overall. However, not all good business is a good fit for us culturally. We only take on new business that aligns with our values, is interesting for our people to work on, and has a great local or global impact.
04 How do we staff projects?
The core idea behind how we staff is that you will never be alone in a project. When staffing our projects, we first start by going through your preferences and ambitions for learning, be it customer location, the field of business, or some particular technology. We then go through your learning and self-development targets and do our best to match all of the above to a project. We get multiple projects and new openings in existing projects each month. If there isn’t a perfect fit immediately, we try to find a spot for you in an existing project or take some time while you work on internal projects, or get deeper into onboarding.
05 What do people do in between projects?
Client work is our number one priority, but we’ve gotten pretty good at making the most out of the normal in-between time in the consulting business. Maybe you’ve just joined us, your project has just ended, or you’re rotating out of one and looking for new opportunities, it can sometimes take a while to find the next client project. These are great opportunities to take training, dive into a new topic, or help out with internal development. Your time in between projects does not affect your pay.
06 Is it ok to work remotely?
It depends on the project in question, as we choose the option that fits best with each client. Sometimes projects are multisite, at other times, there are more on-site visits, and on rather rare occasions, we are 100% remote. That said, we love to see each other every once in a while and spend time together at get-togethers and occasional in-person meetings.
