We are THG, a global ecommerce group on a mission to be the global online leader in beauty and sports nutrition. Our portfolio of leading retailers and brands such as LOOKFANTASTIC, Myprotein, ESPA, Perricone MD, and Cult Beauty form our two core businesses: THG Beauty and THG Nutrition. From Manchester to New York, we’re powered by a team of over 2500 people who work together, lead by example, and think BIG.

Technology is the driving force behind THG, and it starts with our people. We are ambitious with our goals and challenge conventional thinking. THG Technology is different because we support every single person to make massive impact and drive their own work. Our people are always learning, and we work every day to ensure our technology, from our software platforms to our hosting services, to our M.L capability and beyond, is world class. This enables us to keep powering THG and our partners on a global scale.

We’re looking for a Senior BI Engineer to take technical ownership of our finance data platform within THG. This is a high-impact role for someone passionate about data architecture, modern tooling, and enabling the business through data-driven decision-making. You’ll be a strategic voice in how we shape the future of our BI ecosystem and platform — from modernising legacy architecture to guiding our transition into the cloud and scalable, AI-ready solutions. As a technical lead within the Finance Data Team, you’ll work across teams, mentor fellow engineers, and directly influence business-critical reporting and analytics capabilities.

As a Senior BI Engineer you will:

• Lead large-scale data projects across infrastructure, reporting, and architectural streams.
• Take ownership of our current BI data platform (SQL Server, SSRS, SSAS, Superset, Tableau) and drive continuous improvement.
• Mentor and support team members, review code, and set engineering standards across the BI estate and improve current processes and ways of working.
• Design and implement scalable data models and efficient ETL pipelines.
• Play a key role in our journey from on-prem SQL Server infrastructure to cloud platforms — contributing to architectural design, strategy, and migration plans.
• Collaborate closely with finance leadership and stakeholders to define requirements, communicate insights, and ensure the right data gets to the right people.
• Champion the adoption of modern BI tooling, AI-driven capabilities, and best practices in data engineering.

What skills and experience do I need for this role?

• 5–10 years of experience in BI or data engineering, with a proven track record in technical leadership roles.
• Expert-level SQL and deep experience with the MS BI stack (SQL Server, SSRS, SSAS).
• Hands-on experience with Python, particularly for data manipulation and API integrations.
• Strong background in cloud architecture and migrations, ideally with exposure to GCP or other cloud technologies.
• Excellent understanding of data modelling, query optimisation, and performance tuning at scale.
• Ability to bridge the gap between technical and non-technical stakeholders, translating business needs into scalable solutions.
• A collaborative, innovative mindset and a passion for pushing BI forward.
• Experience with finance data domains or reporting in financial environments.
• Exposure to modern BI tools like Superset, Tableau, or Looker.
• Interest in or experience with AI and ML-enhanced analytics.

What’s in it for me?

• Access bespoke development programmes that have been designed and developed by our in-house L&D team.
• Continued development through our upskilling programme that is delivered in partnership with an industry-leading training provider.
• Enhanced Leave: 25 days annual leave plus bank holidays.
• Don’t want to work on your birthday? We don’t either! Enjoy your day off on us!
• Enhanced maternity and paternity pay, depending on length of service.
• Up to 10 days compassionate leave.
• Buy back up to 3 days each year.
