How you will Energise Our Team 🤝

Valda Energy is investing in a modern data platform built on Microsoft Fabric, transforming how data is integrated, managed and used across the business. We’re looking for a Junior Data Engineer to join our growing Business Intelligence team and help build scalable data solutions that support reporting, analytics and automation.

This is a great opportunity for someone with a strong technical foundation and a passion for data engineering and software development. You may have experience from a junior commercial role, placement, internship or academic projects, or be a recent graduate ready to take the next step.

Working alongside experienced data engineers, you’ll develop data pipelines, integrate data from multiple systems and build your expertise in modern cloud technologies and data platforms. Experience with Microsoft Fabric, Azure or the wider Microsoft data ecosystem is beneficial but not essential — we’ll provide support and mentoring as you grow.

• Developing and maintaining data pipelines using Microsoft Fabric to ingest, transform and deliver data from a variety of internal and external sources

• Building scalable data solutions that support reporting, analytics and business automation across the organisation

• Troubleshooting data pipelines, identifying issues and implementing improvements to reliability and performance

• Supporting the automation of manual data processes, helping improve efficiency and reduce operational effort across the business

• Working closely with BI Analysts and business stakeholders to understand data requirements and deliver practical engineering solutions

• Producing clear technical documentation for data pipelines, integrations and engineering processes

• Contributing to the continuous improvement of Valda's Microsoft Fabric platform, engineering standards and ways of working

• Taking ownership of your personal development by learning new technologies, sharing knowledge and developing your data engineering capability

The Spark we're Looking For 🔍

• A degree in Computer Science, Software Engineering, Data Science, Mathematics or a related discipline, or equivalent commercial experience

• Around 12 months' experience in a data engineering, software engineering or data platform role, or demonstrable experience through university, personal projects or internships

• Experience building or supporting data pipelines (ETL/ELT) using Python or PySpark, with an understanding of data warehousing or Lakehouse concepts

• Exposure to Microsoft Fabric, Azure Data Services or the wider Microsoft data ecosystem, with a genuine interest in modern cloud-based data platforms

• Strong analytical and problem-solving skills, with a structured approach and a passion for learning new technologies

• Experience working collaboratively within a team, with good communication skills and the ability to explain technical concepts to non-technical stakeholders
