Are you excited to learn new things? Want to develop and own a product? If so, we've got the job for you!


"We make people happier - one Smiley at a time"


We're offering a great opportunity to become part of developing a product that has a positive effect on people’s lives! We need talented and motivated people to join our R&D team to enable growth, and to take our product development to the next level. So, we warmly welcome you, your best buddy, or you and your A-team to join our R&D team.


At HappyOrNot, you will join our team of 86 energetic and motivated professionals, working within a positive company culture that encourages individualism, ownership of responsibilities, and teamwork. You will be contributing to the way in which organizations from over 135 countries around the world measure and improve their customer and employee experiences across multiple channels. 


You will enjoy working with us if you like:

* Solving complex problems with elegant solutions

* Using Functional Programming (Scala or other FP languages)

* Developing a microservices architecture on AWS

* Building "your own product"


We don’t expect you to master all of these, but it would be great if you have experience with some of these technologies we are currently using:


Backends: Scala, TypeScript

User Interfaces: React, Typescript

Data: PostgreSQL for OLAP and OLTP workloads

Infrastructure: AWS, Terraform, Ansible

Basics: Git, Linux command line


In addition to our SaaS solution, we are developing our own hardware, and have development on Android and iOS. Having experience on these would be a happy bonus!


The team:

Our R&D team is multicultural and diverse in personalities, and we all have the same passion to dive in and learn new things. We work both as a team and individually, and all have data driven attitudes in our work. We use Agile methods in our own way and our team enjoys the great autonomy within the company. And even though there's a lot to do, we still have a relaxed atmosphere and never forget to have fun!

Location: Hybrid/On-site/Remote. Our solution development happens mostly at our headquarters at Tampere and Helsinki region, and we hope you are willing to consider moving close to us at some point in the near future.

Positions: We're hiring multiple persons for different roles in our R&D team, so feel free to send an open application, anytime.
