DNV - Energy Systems' Analytics and Digitalization group is seeking a Business Intelligence Developer to join our team, based out of our Gdynia, Poland office.

This role is suited to a BI professional who already has practical experience delivering Power BI solutions and can handle standard development assignments with a good degree of independence. The person should understand the full reporting lifecycle, from requirements and source data through transformation and modelling to visualization, deployment and support.

We value pragmatic problem-solving, curiosity and a willingness to learn. The ideal candidate combines strong technical foundations with a user-focused approach and is comfortable working in a multicultural environment where clear communication and reliable delivery are important. Below we include a list of typical job expectations for this position.

The successful candidate should be comfortable communicating technical topics to non‑technical audiences, participating in client discussions and working independently while knowing when to involve other team members. Attention to quality, maintainability and user experience is essential.

The role is part of an international environment, with close collaboration across global teams, particularly in the US. It offers a high degree of autonomy and ownership, as well as opportunities to build strong partnerships across different locations and time zones. Occasional business travel to the US or other locations for meetings, conferences and similar business events may be part of the role, providing valuable opportunities for in‑person collaboration and relationship building.

• Demonstrates foundational AI literacy by using approved AI tools for routine analytical and communication tasks, writing clear prompts, recognizing tool limits, staying curious and flexible as tools evolve.
• Take ownership for the quality and reliability of AI‑assisted work by reviewing outputs for accuracy, bias, and fit before using them.

• Ability to work independently and take ownership of assigned tasks and deliverables.
• Ability to gather, challenge and refine requirements with business stakeholders.
• Ability to collaborate with Data Engineers, Analysts, Product Owners and other BI professionals.
• A solution‑oriented mindset, with the ability to recommend improvements rather than only implement instructions.
