The Impact you bring to Cognite

As a Principal Full Stack Engineer, you'll be a key player in designing, building, and maintaining both the frontend and backend of industrial data platforms and applications. You'll have the opportunity to:

  • Drive architectural decisions and lead the implementation of scalable full stack solutions across a diverse technology landscape, taking ownership of complex problems from concept to deployment.

We're seeking a proactive and skilled engineer who is passionate about quality, user satisfaction, and building robust, end-to-end solutions.

  • You love making users happy and are committed to creating products they truly want to use 😄
  • You're skilled at prioritizing your tasks and distributing your time and resources most efficiently to optimize for impact.
  • You write well-structured, efficient, and maintainable code and actively champion code quality.
  • Expert knowledge of computer science with strong competencies in data structures, algorithms, and software design.
  • Relevant and hands-on concentrated experience with software development in one or more programming languages (e.g., Kotlin, Java, Python, or Rust).
  • You possess deep expertise in modern JavaScript and TypeScript, with extensive experience in leading frontend frameworks (e.g., React, Angular, Vue, or similar component-based architectures). Familiarity with state management patterns, build tooling (Webpack, Vite), and testing frameworks is highly valued.
  • Hands-on experience with large-scale cloud deployments (AWS, GCP, or Azure) and Kubernetes.
  • Strong problem-solving skills, technical troubleshooting, and diagnosing complex system issues to ensure optimal performance and minimal downtime.
  • Proven ability to prioritize work for maximum impact.
  • You're comfortable learning new coding languages and choosing the best tool for the job.
