Job description

👋 We’re Attensi, a tech company born in Norway with a passion for gamified simulation training. Since 2012, we’ve grown into a global player, with solutions trusted by some of the world’s biggest brands across 150+ countries and 50+ languages.

We combine gamification, realistic interactive scenarios, and decision-driven dialogues, all powered by our own game AI, to deliver immersive, hands‑on learning experiences that scale across large organizations and drive real behavior change.

Our clients include Circle K, BCG, PwC, Accenture, KPMG, ABB, Zurich, and Novartis. Today, we’re a team of 240+ Game Changers across Europe and the US, with 120 of us at our HQ in Oslo.

We’re looking for a Unity Developer to help us create world‑class gamified learning experiences.

What you'll do:

You’ll join a cross‑functional product team that blends technology, creativity, and purpose. Working closely with designers, artists, and other developers, you’ll build gamified simulations that don’t just look great — they teach, motivate, and drive real‑world impact.

You’ll take ownership of one of our Unity‑based products, guiding it from design to deployment and beyond. This isn’t a ticket factory role; you’ll have room to influence technical direction, shape architecture, and decide how we build the best possible learning experiences.

In this role, you will:

• Design, build, and optimize scalable Unity solutions that run smoothly across platforms (PC, Mac, iOS, Android).
• Write clean, maintainable, and well‑structured code that stands the test of time.
• Work closely with teammates across disciplines to prototype, test, and iterate quickly.
• Solve complex challenges in areas like networking, performance tuning, and tooling.
• Contribute to long‑term architectural decisions and continuous technical improvement.

You’ll be working on products used by hundreds of thousands of people worldwide, helping shape how organizations learn and grow through play.

Who you are:

You're an experienced Unity developer who takes pride in building things that are technically solid, efficient, and enjoyable to use. You think about both the big picture and the small details that make a product feel great.

You enjoy collaborating with designers, artists, and other developers, and you like sharing ideas just as much as learning from others. You care about clean architecture, good systems design, and making technology work smoothly for users.

We think you’ll bring most of the following:

• A bachelor’s or master’s degree in game development, computer science, or equivalent experience
• Proven experience developing and shipping products in Unity (experience with Unreal or other engines is a plus)
• A solid understanding of software architecture, performance optimization, and cross‑platform development
• Hands‑on experience in one or more of the following: UI systems, networking, rendering, or gameplay architecture
• A pragmatic, collaborative mindset with an eye for quality and delivery

If you want to build high‑quality products, take real ownership, and see your work in use worldwide, you’ll fit right in!

What do we offer?

At Attensi, you’ll become part of an exciting and rapidly growing scale‑up that is 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 cultural and academic backgrounds.

We’re committed to helping people grow with us, and you’ll have the opportunity to shape your role over time. Expect exciting challenges in a dynamic and 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.
