Job description

Do you have proven experience designing Power BI dashboards and building ETL workflows using Python and Airflow?

Are you a British passport holder with strong SQL and Oracle expertise, ready to contribute to one of the UK’s largest infrastructure projects?

Are you excited by the prospect of using your data engineering skills to deliver a project that will help power the UK for decades to come?

The Opportunity

This is a rare opportunity to contribute to one of the UK’s most ambitious and high‑profile infrastructure programmes—a £46 billion nuclear new‑build project that will shape the nation’s energy future for decades to come.

As part of an expanding data and analytics function, you’ll join a forward‑thinking organisation committed to innovation, efficiency and sustainability. This role has arisen due to ongoing growth and the need to enhance internal data capabilities to support the scale and complexity of the programme.

The successful candidate will be at the heart of data‑driven decision‑making, developing tools and systems that directly support project delivery, operational excellence and regulatory compliance. You’ll benefit from a collaborative environment, flexible hybrid working and the chance to work with cutting‑edge technologies that influence one of the UK’s most significant engineering endeavours.

Your duties and responsibilities will be:

• Design and develop interactive dashboards and reports using Power BI.
• Build and maintain data pipelines and ETL workflows using Python and Airflow.
• Manage and optimise SQL and Oracle databases to ensure high performance and reliability.
• Lead end‑to‑end data and reporting projects, from requirements gathering through to delivery.
• Collaborate closely with cross‑functional teams to deliver consistent, accurate and accessible data.
• Uphold data quality, governance and security best practices.
• Provide technical guidance and mentorship to junior data professionals.

You will have the following qualifications & experience:

• Proven experience developing and deploying solutions using Power BI.
• Strong proficiency in Python, particularly for data processing and automation.
• Deep working knowledge of SQL and Oracle databases.
• Hands‑on experience with Airflow for workflow orchestration.
• Understanding of ETL/ELT processes and data architecture principles.
• Strong project management and communication skills.
• Fluent in English.
• Must hold a valid British passport (due to project security requirements).

It’s great if you also have the following:

• Experience working in a regulated, engineering or energy environment.
• Familiarity with cloud technologies such as Azure, AWS or GCP.
• Knowledge of data governance frameworks and data modelling techniques.
• Previous experience mentoring or leading a small data team.
• Additional language skills (French desirable).

The setting for the role

You’ll be based in Bristol, working on a hybrid model (three days from home per week – flexibility available). The project office combines the professionalism of a major engineering consortium with a collaborative, innovation‑driven culture. You’ll work alongside industry experts passionate about sustainable energy and technological excellence, in an environment that rewards initiative, creativity and results.
