About Magnus Consulting
We’re Magnus Consulting – an award-winning B2B consultancy helping mid-sized tech, financial services, and professional services organisations unlock growth through smarter commercial and marketing strategies. We’re a certified B Corp and named one of the FT’s top UK management consultancies. We deliver bold thinking, real insight, and measurable results.
We're now hiring a Senior Data Scientist on a 6+ month contract to help us build the next of data-driven commercial tools.
The Role
This is a strategic and hands-on role for a data scientist who can turn unstructured data into structured insight and shape how we use AI and analytics in our business. You’ll build a unified data warehouse, benchmark our research and analysis, and uncover new commercial opportunities within our internal assets.
What you'll do
You’ll lead a high-impact project to transform our internal data into a strategic asset, laying the foundations for future analytics, AI tools, and commercial insights. Your work will focus on four core areas:
1. Build the Data Backbone
· Design and implement a smart, centralised data warehouse to organise our research, transcripts, and project outputs
· Automate data pipelines to collect, clean and update information from multiple sources
· Ensure all data is structured, labelled, and accessible for analysis
2. Unlock Insights & Value
· Use advanced analytics and machine learning to identify trends, patterns and performance opportunities
· Create benchmarks and reusable insight frameworks to guide both internal strategy and client-facing work
· Spot monetisable opportunities in our data that could become new tools, models, or products
3. Power AI-Driven Tools
· Train and fine-tune AI models using cleaned internal data
· Connect data pipelines to AI tools to deliver more useful, context-aware outputs
· Ensure models are maintained, explainable and delivering consistent value over time
4. Safeguard Trust & Communicate Clearly
· Apply best practices in data security, privacy and governance, with clear policies around access and use
· Monitor for bias, drift or errors in AI outputs and ensure compliance with legal and ethical standards
· Translate technical findings into clear, business-focused recommendations for internal stakeholders
What we're looking for
· 7+ years in data science, analytics or data engineering, preferably in B2B or consultancy environments
· Experience building centralised data platforms, pipelines, and models from the ground up
· Familiarity with tools like SQL, Python, dbt, Airflow, Spark, and modern cloud environments
· Strong understanding of how data supports commercial decision-making
· Confidence presenting technical ideas in simple, clear to non-technical audiences
· A bias for action, autonomy, and the ability to navigate ambiguity
Contract details
· Day rate: £DOE (outside IR35)
· Duration: 6-month initial contract with extension potential
· Location: Hybrid (London office every Tuesday)
