Helsinki Junior

Developer, summer 2021

Are you a motivated junior developer who’s looking for a place to gain experience from real-life projects? We’re hiring enthusiastic learners to join our development teams in the Helsinki capital area for summer. The application period ends on Feb 28, 2021.

What we’re looking for

We don’t expect you to excel in everything before joining us, but we do call for eagerness and the ability to learn new things. You can compile your application the way you want, but a few things we require from all applicants along with a CV is:

  • A project to showcase your skills in writing readable and well-structured code. Our pre-assignment is tailor-made for this purpose, and we encourage you to do it. A hobby/work project in a publicly available repository can also do the job if you believe it demonstrates your skills adequately. 
  • Are located in or able to move to the Helsinki capital area. If the situation requires, the work will start remotely but will move to the office once it’s safe. Unfortunately, we’re unable to offer assistance for relocation in our junior positions. 

You’ll have a head start in our projects, and therefore, an advantage in the recruitment process if you: 

  • Know at least one programming language/stack well. Knowing more languages with different abstraction levels and paradigms will come in handy.
  • Are familiar with web stack (frontend+backend tech, communication protocols, relational databases, etc.). Most of our client projects have aspects involving the web, and thus, knowing the web stack will help you.
  • Have previous experience in teamwork with good development practices (e.g. code reviews) and in using Git. As a junior employee, you’ll be working as part of one of our development teams, so knowing good development practices is a plus. 
  • Make it through the day in English and/or Finnish. The working language in all of our projects is one or the other. When working with our clients in Finland, Finnish is an advantage but not a strict requirement.

If you don’t check every box on the list, don’t worry. We’re seeking potential, not ready-made professionals.

What we offer

  • Meaningful projects that solve real-life problems. You’ll be spending your trainee period as a part of one of our development teams, working with our leading experts, building solutions that solve actual business or societal challenges.  
  • A passionate community of experts to join. As a Reaktorian, you’ll have talented and experienced colleagues around you, ready to help you whenever you need it. 
  • A workplace where you can feel at home. We’re not looking to hire your work-self, but the person you are as a whole. At Reaktor, we let you be the same person at work as at home.
  • A paid trainee period that is not all about work. We Reaktorians take our work seriously, but we also like to have fun. Thus, we’re having regular team days and doing non work-related activities together.

How to apply

We’re eagerly waiting for your application! The application period ends on Feb 28, 2021. Make sure we receive your application with a CV and code sample by then. 

Here’s a checklist you can follow to ensure you’ve sent us all the relevant materials. You’re all good if your application includes:

  • A link to your pre-assignment solution on GitHub or similar. Your code sample is often the first thing we look at in an application, so make sure it represents your current coding skills.* 
  • A cover letter in which you tell us about yourself and why would you like to work at Reaktor. There’s no need to be formal here. We appreciate seeing your personality through the letter. 
  • A CV or a link to your LinkedIn profile that we can see what you’ve done previously. We’re not only after people with tons of work experience under their belt. We’re also interested in development experience gathered from hobby projects or studies. 

* The assignment is an important part of our recruitment process. It is designed to be fun and shouldn't take too long to complete. However, we recognize that taking the extra time for completing it might not be possible for everyone. In this case, drop us a line at, and we can discuss alternative options.

What happens after you hit “Apply”

Finally, here is what to expect when hitting apply (or technically submit):

🕵️ We’ll go through all the applications once a week. We’re responding to all the applicants individually, so it might take a little while before we get to your application but you’ll definitely hear from us.  

✉️ After reviewing your application, if we think that you’d be a good fit for Reaktor, we’ll invite you to an interview. If we feel like this is not yet a good time to start our journey together, we’ll let you know the reasons behind our decision. 

👋 Our interview process includes two rounds, both with your potential future team members. You can read our previous junior employees’ comments about the interviews on our blog.

📅 We’ll make the hiring decision after the second interview. Sometimes, we’re able to do that soon after but since our project situation is in on-going flux, sometimes it’ll take us a little longer to evaluate the situation. All hiring decisions are made by the end of March.
