Job Description

We’re looking for a hands-on software architect to join our Helsinki office. Your job will be to be a senior member of a cross-functional software development team and work “in the trenches” on a wide range of interesting and challenging projects.

If you’re an experienced software architect who is looking to do actual development work and keep current with the latest technologies, you’re just what we need. As a software architect, you desire both the freedom to shape your own role and the responsibility to deliver a wide range of development tasks. You can also draw on your experience to coach your teammates and find the best way to meet our clients’ goals.

At Reaktor, we constantly challenge ourselves and our clients to achieve the best possible outcome. You’ll get to work on meaningful projects and be a part of a unique community of passionate professionals. We’re all about setting you up to succeed. Your job is to be one of the most experienced members of a very productive and skilled team.

What you’ll do

Your job is to be one of the most experienced members of a very productive and skilled team.

What the role entails:

• Having a lot of freedom and responsibility: our customers hire us to be the experts and they trust us with their most critical projects - and our aim is to be worthy of this trust

• Working on a wide range of projects: each project will be different and mandate a different approach. The only thing in common between them is that they are interesting, challenging and meaningful

• Having the freedom to impact how you work: your team chooses the approach, technologies and methodologies you think will work best in any given situation

• Constantly learning: we do our part to advance our field and always look for better ways to work

• Working with a team that’s not only experienced, but considerate as well: your coworkers are likely as experienced as you are, and they all want you to succeed

As a hands-on software architect, you have:

• Comprehensive and broad knowledge in building digital software products and their associated architectures

• A curious mind that is open to change - we want to continue learning all the time, and you should know your stuff and understand what you don’t know

• An ego that survives being checked at the door. Ideally, you have nothing to prove and are looking to help everyone else rise to their potential

• Tenacity. Rome wasn’t built in a day, and the same thing applies to software architecture

• Working experience with concrete results. We expect you to be able to show us “I did this”

• Note: we’re not looking for a specific amount of experience, but we’ve found out that it usually takes 8+ years of working in the field to reach the expected level

• Fluency in either English and or Finnish and good communication skills (written & spoken)

• The necessary permits for working in Finland

Technologies in our projects

• Technologies commonly used in our projects include TypeScript/JavaScript, Node.js, React, Java/Scala/Kotlin, Clojure, and Python to name a few.

• That being said, our philosophy is that tech is a tool. Do not let lack of a specific technology hinder you from applying to this job.

What we offer

• A cooperative, supportive and friendly community of world-class experts

• Meaningful, pioneering projects with interesting clients

• The freedom to shape and develop your own role – and the support needed to get there

• Continuous training and coaching possibilities

• A workplace where you can truly feel at home

• A healthy balance between work and free time

• Interest groups and clubs by Reaktorians, for Reaktorians

What we’re like

We pride ourselves on a culture that is open, respectful and human. Reaktorians are a friendly, curious bunch – in addition to being some of the sharpest minds around. Doing what others consider unrealistic is our bread and butter.

We work together with our clients to set our projects up for success and help their organizations adapt and remain ahead in a world that is increasingly complex. As a Reaktorian you get to work in and learn from hybrid teams, with experts ranging from engineering to AI, business consulting, design, content and data.
