👋 Hey there! We’re Attensi – a tech company born in Norway with a passion for gamified simulation training. Since 2012, we’ve gone global, and today our solutions are used by some of the world’s biggest brands in 150+ countries and 50+ languages.

We combine gamification, realistic interactive scenarios, and decision-driven dialogues – all powered by our own game AI – to create immersive, hands-on learning experiences. It's a radically new way to deliver high-impact training that scales across large organizations and actually sticks.

We work with some of the world’s largest brands in energy, retail, hospitality, pharma, professional services, and more – including Circle K, The Boston Consulting Group, PwC, Accenture, KPMG, ABB, Zurich, and Novartis. We are currently over 250 Game Changers across Europe and the US – and 140 of us based in our HQ in Oslo. 

Ready to Shape the Future of Learning with Powerful, Gamified Technology?
If you're excited about working with Ruby on Rails and building scalable, secure backend systems, we’d love to hear from you. We’re looking for a skilled backend developer who thrives in agile, cross-functional teams, enjoys problem-solving, and wants to help evolve the Attensi Technology Platform—used by hundreds of thousands of users worldwide.

Our backend infrastructure is hosted on AWS, using technologies like Ruby on Rails, .NET Core, PostgreSQL, Redis, Linux, Kubernetes, ArgoCD, and Kafka. We also use GitHub Actions for CI. Experience with any of these is a plus—but we don’t expect you to tick every box. We’re especially eager to connect with developers who have strong backend skills, solid API experience, and a particular fondness for Ruby on Rails.

In this role, you’ll build new features, develop secure and scalable APIs, contribute to discussions around capacity planning, scalability, and security, and help maintain our live environments. You’ll also help shape the core functionality of our LXP-platform, working on the underlying business logic that drives the user experience.

What we offer:
At Attensi, you’ll become part of an exciting and rapidly growing scale-up that’s already a global leader in its field. You’ll work in a flat, open, and collaborative environment, surrounded by committed, smart, and talented colleagues from diverse backgrounds—both culturally and academically.

We’re committed to giving people the opportunity to grow with us, and you’ll be able to shape your role over time. Expect exciting challenges in a dynamic, innovative environment with big ambitions.

We work hard, but we also have a lot of fun! From monthly Attensi-days to sporting events, after-work drinks, parties, game nights, and company trips—we make sure we don’t just work together, we play together too.

Excited to make an impact with us? Let’s talk!
