Ruby on Rails Developer

Would you like to build scaleable solutions that serve thousands of players every day? Attensi is looking for a Ruby on Rails developer to join our Platform team!

Attensi is one of Norway's fastest growing technology companies and today our training is being used by global brands in more than 100 countries and 20 different languages. We make 3D gamified simulation training for large corporations, and are a global leader in our field. Our solutions create a realistic ‘learning by doing’ environment in a virtual 3D setting and makes training fun and engaging! 

As Attensi continues to grow, we are in need of a Ruby on Rails developer to join our Platform team. The team is responsible for continuously developing and maintaining the cloud infrastructure and backend shared by all products in the Attensi Technology Platform. The infrastructure is the backbone for all content distribution and the live experiences of thousands of players on a daily basis.

What will you do? 

As a backend developer at Attensi you will be part of a multidisciplinary team doing agile development, testing and delivery. Your days will be spent working closely with other backend developers and colleagues in and outside of the team to improve and enhance the products in the Attensi Technology Platform. 

Your main responsibilities will be: 

  • Develop the feature set and scalability of the Attensi Technology Platform backend
  • Develop and establish secure and scalable APIs, and influence our technical discussions and decisions with your insight and knowledge. Currently, important decisions revolve around scalability, capacity planning, and security as well as choices related to orchestration of monolithic services and microservices through kubernetes

Any developer on the team will constantly be working on maintaining live environments as well as the development of new functionality. No matter what we code, we are all a fan of lean processes and hassle-free development.

Who are you?

We would love to work with someone that is experienced and possesses good knowledge of API management and backend development with specific emphasis on Ruby on Rails.

In addition, we hope you:

  • Enjoy being hands-on and are eager to share your experience and knowledge
  • Are motivated by the opportunity to contribute to technical discussions and decisions 
  • Consider yourself a team player who thrives on creating value together with others
  • Are passionate about backend development and have a strong understanding of business-critical areas like scalability, capacity planning and security. 
  • Ideally, bring the experience of building and scaling digital products to a large number of users and clients world wide
  • As gamified simulation training is our core business, it doesn't hurt if you have an interest in games and game development either
  • Fluency in English, both oral and written, is a requirement. If you speak Norwegian, that’s great too. 

On the tech side of things, our backend infrastructure is hosted on AWS, and technologies used include: Ruby on Rails, .Net Core, PostgreSQL, Redis, Memcached, Elastic Beanstalk, Linux, Github (and Vue.js for frontend) - experience of working with some of these is a must. Experience with CI/CD tools such as Travis CI, CircleCI, and/or AWS Codepipeline etc could come in handy too. 

Experience of working with Ruby on Rails and some of the other technologies mentioned will be a must in order to succeed in this role.

What can we offer you?

Working at Attensi means working in one of Norway's most exciting and fastest growing scale-ups. Here you get to work on exciting challenges in a dynamic and innovative environment with global ambitions.

We represent a flat, open and free environment, made up by more than a 100 committed, smart and talented colleagues from a variety of backgrounds, both culturally and academically. At Attensi people are given the opportunity to grow with the company and we would be happy to develop the role with you over time. 

Attensi has a young, energetic and social work environment. We work hard, but also have a lot of fun together. Monthly social activities like demo days, afterwork, game nights, company trips or sports events are some of the ways in which we ensure we not only work- but also play together. Our offices are located at Oslo Science Park, which is a vibrant environment shared with many other startups and scale-ups.
