Full-stack developer

Salary €4,000 - €5,500

Are you an experienced full-stack developer interested in joining a tech startup on the verge of going big? Are you interested in digitalizing an industry that is known to be old-fashioned, and want to help build a world-class consumer application? Meet Aatos, an award-winning (top 3 best online services / Grand One 2021) and industry-disrupting legal tech startup. We solve the boring but important problems everyone face in their life, with technology. 

If this sounds interesting to you, keep on reading! 


We are a tech company based in Helsinki, at the Maria01 startup campus. We at Aatos, are building a superior digital legal application to help individuals with their legal needs. By combining the newest technology, design thinking and legal principles we translate legal processes into fluent and fully automated web applications. 

Our aim is to demystify legal processes and offer easy-to-use digital services for everyone. In a short period of time, our legal platform Aatos.app has become a significant player in the field of consumer law. By utilizing features such as multi-platform support, user-centric design and eSigning, Aatos brings the consumer legal industry to the 2020s. Aatos.app is the most advanced and powerful consumer legal platform available and we are currently expanding internationally.

We are now looking to expand our team in Helsinki by hiring software developers to help us develop our platform further and expand to new markets. You’ll be a crucial part of the team on our journey to becoming the number one consumer legal platform in the world.


Tech has been at the core of everything we do from the day we started. Currently our team of 11 consists of 1 designer and 4,5 developers. Four full-time developers and a coding lawyer.   

So, what does our current tech stack and implementation look like? Our frontend is built using Typescript and React (deployed to S3), and our backend consists of Javascript AWS Lambda functions (built using the Serverless Framework). All in all, our whole infrastructure runs on top of AWS and in general different AWS services are highly utilized when applicable. Just to name some keywords here: Lambda, S3, SQS, SNS, DynamoDB, Cognito, Textract, AWS EC2 spot instances (for running our on demand CI/CD worker nodes). Naturally our infrastructure also deploys automatically (Infrastructure as Code).

We have a modern tech stack and we are interested in keeping up with the new. However, this does not mean that we constantly jump from one tech trend to the next, but rather that we always aim to use the right solution for the problem. In the past, this has included contributions to open source libraries, the use of neural networks to solve complex combinatorial problems and implementing our own eSigning platform to digitalize old-fashioned processes.


We are looking for experienced full-stack developer who wish to work in a technical landscape as described above. There is no need for you to have worked with all of the buzzwords listed. However, you should feel comfortable getting up to speed with them. We are looking forward to seeing you grow with the team, but we are also eager to learn new things from you! At this point, our daily work mainly consists of working with Javascript (especially on the frontend side), so strong knowledge of React is a big, big plus. But don’t let this intimidate you. If React is not your number one technology at this point but you feel you could easily catch up, and you maybe have other core competencies such as UX/UI or data-analytics, let us know! We keep the customer experience of our platform in high value, so we see all previous experience working with web applications / mobile applications as an advantage.

At Aatos we work together and involve our whole team into the product development. As a developer at Aatos, you’ll contribute to both building and designing new products as well as making improvements to our existing platform. You will work together with the rest of the tech team but also collaborate with marketing and operations.

As we are building products for the masses and our main customer base is currently in Finland, speaking or understanding Finnish is helpful. 


  • 3+ years of proven full-stack development experience

  • Experience with at least React.js, Javascript, AWS

  • Experience developing web and/or mobile applications

  • Good communication and collaboration skills

  • Desire and ambition to contribute in building the best-in-class consumer application


  • Be a part of and grow with the team to help us realize our vision of becoming the leading digital legal service in the world.

  • Work that truly matters. We offer a unique opportunity to take part in building something disruptive in the field of law and consumer business.

  • We have an open and very flexible working culture, and we value every member of our team.


Apply by leaving a link to your Linkedin profile or a resume+cover letter, and we’ll get back to you soon!
