Junior Developer

Omnium's 'Retail Operating System' powers seamless order management and commerce operations across web, in-store, and every channel in between for the Nordics' biggest retail brands, including Varner, Coop, Stadium, Intersport, and HiFi Klubben.

Eight years in, still building like a startup: no legacy code, high pace, real demand. We've been named one of Norway's 50 fastest-growing tech companies several years running.

We want juniors who are curious about AI and use it as a natural part of how they work — tools like Claude Code included.

You start in second-line technical support, working on real bugs, finding root causes, and shipping fixes — while also picking up development tasks from day one. It's the fastest way to actually understand a complex platform.

You'll work inside our tech team alongside Support, Customer Success, and Onboarding, join client conversations when things get technical, and pair with senior developers on lasting solutions.

• Diagnose and fix advanced support cases, focusing on root causes, not workarounds
• Support first-line escalations with clear technical guidance
• Join client conversations that need developer depth
• Ship backend fixes, improvements, and new features across the stack
• Work daily with backend code, integrations, and APIs
• Use Claude Code and other AI tooling as part of your normal workflow
• Document findings so the whole team gets sharper over time

Fresh out of a CS or software engineering degree, or 1–2 years in the field. Analytical, structured, genuinely curious how things work under the hood, and comfortable in a codebase or a client call.

You don't need to know our platform yet. You need to be curious, quick to dig in, and motivated to grow fast.
