Full Stack Developer
Reaktor's award-winning tech community is looking for full-stack developers to join us in Helsinki.
If you are in your element with a full software development cycle, have a passion for solving human problems with a holistic approach, and are curious to experience working in a low-hierarchy environment, you might just be what we're looking for.
As a Full Stack developer at Reaktor, your job is to be an expert in a range of software development responsibilities spanning the entire software development lifecycle, from front-end to production.
Your daily tasks include:
Working together with the client’s tech and business teams and helping them to pick the right technologies suitable for their needs.
Implementing new features that require changes to frontend applications, backend servers, and/or databases, even on infrastructure.
Delivering the client and the team with a world-class technical expertise.
Other software development-related tasks, such as debugging, designing, and participating in creating the architecture.
You are a curious-minded developer who is comfortable working on both the back-end and front-end of an app and understands the role of infrastructure in everyday tasks.
To thrive in this position, you’ll need:
Experience in a broad range of software development modalities (backend, frontend, ops, and consulting skills).
We don’t have a hard limit with years of experience, but we’ve noticed that these competencies usually take several years to accumulate.
Previous experience with at least one common server-side programming language. Currently, many of our projects are built with TypeScript/JavaScript and Node.js. But, Java/Scala/Kotlin, Clojure, and Python are also used.
Strong knowledge of at least one common client-side language and framework. We often use TypeScript/JavaScript and React on our web app projects and Swift, Java/Scala/Kotlin, or TypeScript/JavaScript React-native on mobile.
Relevant skills to create new backend services and build CI/CD pipelines when the project requires.
Foundational knowledge in DevOps, including Continuous Integration (CI), automated deployment, and test automation
Know-how on databases (e.g., PostgreSQL).
To be comfortable engaging with the client stakeholders when needed.
Fluent verbal & written English skills. Finnish skills are seen as an advantage.
Why join us?
For two decades, we’ve been developing qualities and capabilities for adapting, reacting, and supporting change – building Reaktor to hold up in a fast-paced environment while ensuring the well-being of our people.
At Reaktor, you'll have the opportunity to work across a range of industries, including Aero, Gaming & Entertainment, Industrial and Retail. You might also be collaborating with clients in Defense & Security, Healthcare and the Public Sector.

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.
