Senior Software Engineer  

Join a collaborative and forward-thinking team working on CDM - a strategically important initiative with strong executive support and a clear path for future growth. CDM is designed to modernize and unify data management workflows across geoscience applications, with a focus on modularity, scalability, and deployment flexibility. You’ll be part of a close-knit development team (~3 developers, tester, and shared product leadership), working alongside a second team focused on evolving one of our existing products into a CDM module. The teams share a backlog and plan together, and mobility between them is encouraged.

Ownership matters here! The team has full control over the product’s direction, architecture, and delivery. Your voice will shape what we build and how we build it. Our customers operate in complex data landscapes, often spanning petabytes of data across both local and cloud environments. This presents unique challenges, and opportunities,  for building robust, scalable, and high-performance solutions.

This position is based in either our London or Oslo office. While primarily on-site, we offer flexibility for remote work when needed.

Your day-to-day will include:

• Building backend services in Go and C#, contributing to a modular, service- and event-driven architecture.
• Using NATS for distributed messaging and Protobuf for consistent data contracts across components.
• Working with a Vue-based frontend and integrating it with backend services.
• Managing local SQLite databases and integrating them with Grafana dashboards and interactive Vue pages.
• Building CI/CD pipelines to support development and deployment workflows.
• Collaborating on authentication and RBAC strategies (e.g., Windows Auth, OAuth, OIDC).
• Writing clean, maintainable code and following best practices.Communicating clearly with team members and stakeholders.
• Contributing to architectural decisions and helping shape the future of CDM.

• A Vue-like framework (e.g. modern Typescript frameworks such as Angular or React)
• Relational databases (e.g. SQL Server, SQLite, PostreSQL etc) and understanding of database design, optimization and query building.
• Familiarity with Python
