What you tell your friends you do: “I develop the identity and access management (IAM) that keeps my company secure and seamless, shaping the product experience as much as the code.”

Key Responsibilities:

  • Build and evolve backend services in C#/.NET, owning key parts of IAM-domain.
  • Design and maintain integrations between portal, backend services, and assorted third-party systems.
  • Work across a broad surface area: backend, React frontend, and the DevOps infrastructure that keeps everything running.
  • Shape features with the product team - scoping, estimating, and challenging the “why” behind what we build.
  • Mentor teammates, contribute to architectural discussions, and help facilitate agile ceremonies.
  • Support a team that owns everything end-to-end, from infra to UI.

How will the work look like

  • Working as part of a self-driven team of seven that owns an entire “app within the app” - full flow, full responsibility.
  • Using and improving our DevOps setup (Terraform, CI/CD, cloud platforms), building on the foundations already established.
  • Mostly focusing on backend, but with the opportunity to jump into frontend and infrastructure when it makes sense.
  • Collaborating closely with other engineering teams and other disciplines to balance technical depth with user and business needs.
  • Bringing your experience and the right attitude to help the team scale.
  • We are using Frontegg as IDP (not important to have experience), SCIM, SSO, OAUTH 2.0

Requirements

  • 5+ years of experience with C# or .Net, including building and maintaining production-grade systems.
  • Engineer with a strong sense of ownership, capable of operating effectively across a broad and evolving technical landscape.
  • Solid understanding of DevOps practices, CI/CD pipelines, and infrastructure-as-code approaches (preferably Terraform).
  • Practical experience working within Identity & Access Management (IAM) or related identity/security domains.
  • Demonstrated ability to collaborate cross-functionally, coordinate work across teams, and actively contribute to architectural design and technical decision-making.
  • Product-oriented mindset with the ability to consider business goals, user needs, and system impact, not solely implementation details.

Nice to have:

  • Experience with Azure cloud
  • Experience with React
  • Ability to travel abroad once a year for an on-site team building (Oslo, Norway)

We offer*:

  • Flexible working format - remote, office-based or flexible
  • A competitive salary and good compensation package
  • Personalized career growth
  • Professional development tools (mentorship program, tech talks and trainings, centers of excellence, and more)
  • Active tech communities with regular knowledge sharing
  • Education reimbursement
  • Memorable anniversary presents
  • Corporate events and team buildings
  • Other location-specific benefits
  • not applicable for freelancers
