DATA SCIENCE MANAGER – PRICING
3-6 Month Contract | £550-£650 per day (Outside IR35)
Hybrid – UK (1-2 Days Onsite)
THE COMPANY
A pioneering player in the circular economy is looking for a hands-on Data Science Manager to take ownership of their pricing strategy during a period of major growth. Founded over 20 years ago, the company has scaled from a small UK start-up to a global business with 1,000+ employees, multiple international offices, and a rapidly expanding Direct-to-Consumer offering. Backed by recent private equity investment, they are now doubling down on data, automation, and best-in-class pricing capability.
THE ROLE
This is a high-impact opportunity to lead and mature the pricing function within a fast-paced, data-rich environment. You’ll manage a small team of Data Science and Pricing specialists across the UK and US, while partnering closely with commercial leadership to build a world-class pricing engine.
You will take full ownership of the end-to-end pricing product – spanning both acquisition pricing and resale pricing. The company operates in multiple markets, including a large and fast-growing US textbook vertical, so you’ll shape differentiated pricing strategies based on product type, demand, and geography.
WHAT YOU’LL DO
* Lead a team of 3 (UK & US) across Data Science and Pricing
* Own the full pricing product lifecycle – modelling, deployment, testing, optimisation
* Improve existing algorithms and develop best practices for pricing across markets
* Deploy models in collaboration with the Data Platform/Engineering teams
* Work directly with senior commercial stakeholders to translate insights into action
* Operate in a high-change environment where speed, experimentation and adaptability are key
YOUR SKILLS
* Strong hands-on Data Science background (Python essential)
* Experience managing Data Science or Pricing teams
* Proven ability to build, optimise, and operationalise pricing models
* Excellent communication skills – able to influence senior non-technical leaders
* Entrepreneurial mindset – comfortable working in ambiguity and solving problems end-to-end
* Customer and product-focused, with a commercial approach to decision-making
TECH STACK
Python | SQL | GCP | Tableau
WHY APPLY?
Join a mission-led, high-growth business where data makes a tangible, measurable impact every day. You’ll shape a critical product, influence the commercial strategy, and help build a best-in-class pricing capability at a global scale.
