Adroit designs, delivers, and embeds AI-ready cloud platforms for organisations that need to move fast without compromising security or compliance. We are engineer-led and outcome-focused, trusted by market leaders to cut through the noise, simplify delivery, and accelerate measurable returns.

We are looking for a hands-on Senior Power BI Developer to continue and extend an existing analytics initiative for a key client. The focus is on building robust data models, improving performance across large datasets, and ensuring reliable reporting across live and archive data.

You will work across multiple existing Power BI reports, refactor and optimise complex queries, and integrate a range of API data sources. The environment is data-heavy, and the right person will be comfortable getting deep into the detail while keeping an eye on scalability and governance.

• Own and extend existing Power BI solutions across multiple .pbix files and workspaces
• Design and refine data models to support complex analytical and operational reporting needs
• Optimise DAX calculations and query performance for large live and historical datasets
• Refactor legacy queries and datasets for scalability, maintainability, and reuse
• Integrate and visualise API-driven data, including domains such as Horizons, Faults, Maps, Models, and Seismic where available
• Build and customise visuals to support data duplication and data quality analysis
• Structure and maintain hierarchical data models that can be reused across reports and subject areas
• Apply Power BI governance and deployment best practice across workspaces, datasets, and reports
• Use automation or AI tools, such as Copilot, to streamline repetitive development and documentation tasks
• Collaborate with client stakeholders to clarify requirements, prioritise changes, and validate outputs

• Proven experience as a Senior Power BI Developer or BI Engineer delivering production-grade reporting solutions
• Strong Power BI skills across data modelling, DAX, performance optimisation, and custom visuals
• Demonstrable experience handling large datasets and complex query pipelines across live and archive data
• Experience refactoring and standardising existing Power BI assets for scalability and maintainability
• Confidence integrating and shaping data from APIs and other external data services
• Good understanding of Power BI governance, deployment pipelines, and performance best practices
• Experience in data-heavy domains such as engineering, geoscience, or energy is highly desirable
• Ability to communicate clearly with both technical and non-technical stakeholders and challenge requirements where needed
• Comfort using automation or AI tools (for example Copilot) to accelerate development and documentation
• Available full-time for the full 3-month term, with no conflicting roles or engagements

• Initial 3 month contract focused on continuing and stabilising an existing Power BI programme of work
• Immediate priority on performance optimisation, query refactoring, and consolidation of existing reports
• Subsequent focus on extending data models, integrating additional API sources, and improving data quality and duplication analysis
• Hands-on role with clear deliverables and regular stakeholder touchpoints, rather than an advisory or part-time engagement

This role is a chance to have a very tangible impact in a short time frame. You will take ownership of a live Power BI landscape, improve performance and structure, and leave the client with cleaner, more reliable analytics.

If you enjoy taking complex, messy datasets and turning them into fast, trusted reporting assets, and you are able to commit fully for three months without other concurrent roles, this will suit you well.

At Adroit, you will work with a team that values clear thinking, strong engineering practice, and measurable outcomes. You will have the space to focus on delivery while knowing that the client relationship and context are handled well. If you like to leave reporting environments faster, cleaner, and easier to maintain than you found them, this will be a good fit.
