I'm working with a market-leading trading firm at the heart of the UK's energy transition. They use advanced forecasting and trading technology to help balance the National Grid, playing a crucial role in supporting the UK's decarbonisation efforts.

This is a small, highly skilled team where technology and trading go hand in hand. You'll be building and optimising the internal data infrastructure that powers critical trading decisions. This is a hands-on role with real impact, and your work will be used daily by traders and data scientists.

What they're looking for:

• Strong skills in Python and SQL
• Experience building end-to-end data pipelines (streaming or batch)
• Solid understanding of AWS (EC2, ECS, RDS, S3)
• 2+ years of relevant experience in data engineering
• Great communication skills - comfortable collaborating with traders, devs, and data scientists
• Happy to work onsite in central Bristol most of the time

Nice to have:

• Experience in trading, betting or energy markets
• AWS data engineering tools, Docker, DevOps or Apache suite
• Analytical background and data modelling experience

Why this role?

• Private medical, dental & life assurance
• 30 days annual leave + public holidays
• Cycle-to-Work scheme
• Annual company ski trips & regular socials
• Further training & development opportunities
• Direct access to leadership - no red tap

This is a brilliant opportunity to work with cutting-edge data systems that directly impact trading strategy in a company where your ideas will be heard and your work will make a difference.
