With unmatched industrial heritage and a comprehensive suite of AI capabilities, including low-code AI agents, Cognite accelerates the digital transformation to drive operational improvements.

We thrive in challenges. We challenge assumptions. We execute with speed and ownership. If you view obstacles as signals to step forward - not backwards - you’ll feel right at home here.

Our Moonshot is bold: Unlock $100B in customer value by 2035, and redefine how global industry works. Join us in this venture where AI and data meet ingenuity, and together, we will forge the path to a smarter, more connected industrial future.

How you’ll demonstrate Ownership

As the first line of defense for securing privileged customer data, our work is crucial to customer and company success. We operate where security, infrastructure, and product meet: designing authorization, identity, and audit solutions that are fast, correct, and observable. As a Principal Engineer, you will take ownership of security-critical backend systems, directly impacting how our platform is secured and used.

• Designing and scaling resilient gRPC/HTTP APIs and microservices on Kubernetes, ensuring high availability, low latency, and ease of integration for other internal teams.
• Driving backend innovation by writing clean, maintainable code and refining our service architecture to support rapid product growth.
• Leading development initiatives including threat modeling, performance tuning, and reliability engineering to harden our systems against evolving security challenges.
• Mentoring engineers and collaborating across teams to shape our technical roadmap and foster a culture of secure-by-default engineering.

Required Qualifications

• Significant experience building and operating distributed backend systems in a modern, typed language.
• Strong proficiency in Kotlin. We value deep expertise in either language and a pragmatic approach to choosing the right tool for the job.
• Deep expertise in modern authentication and authorization concepts (e.g., OIDC, OAuth2, RBAC/ABAC) and their practical application in building secure services.
• Hands-on experience with cloud-native technologies, particularly Elasticsearch and cloud platforms like GCP, AWS or Azure.

Preferred Experience

• A proven track record of owning services in production, from initial design and development to deployment, monitoring, and incident response.
• A collaborative and pragmatic mindset, with good communication skills and a desire to mentor others.
