đź“… Position type: Full-time, hybrid
MPB is seeking a skilled and motivated Senior Data Scientist to join our Data & Analytics team, working primarily across our Product and Revenue functions.
In this role, you will translate MPB’s unique proprietary data into world‑class search and discovery experiences, as well as data‑driven features, optimisations and enhancements to the customer journey. You will partner closely with Product Managers, Engineers and commercial stakeholders to build intelligent systems that drive measurable business impact.
The ideal candidate has a passion for working in a fast‑paced environment and a proven track record of creating impact by combining traditional statistical rigor with modern AI capabilities. You’ll report to the Lead Data Engineer and work alongside another Senior Data Scientist in a collaborative, fast‑paced environment where autonomy and ownership are encouraged.
What You Will Be Doing
* Applied AI Mindset: Hands‑on experience with NLP and Generative AI, pragmatic and outcome‑focused.
* Quantitative Analysis: Uncover behaviour, model user interactions, spot trends and opportunities that elevate search and discovery.
* Product Decisions: Partner with Product and Engineering teams to define problems, design experiments (A/B testing), and execute product launches.
* Scalable Intelligence: Design, develop and evaluate machine learning models—ranking, recommendation, and pricing engines—that integrate with our Platform.
* AI Solutions: Identify where LLMs and agentic workflows can augment traditional Data Science to extract value from unstructured data.
* Data Integrity: Collaborate with Data Engineers to ensure pipelines feeding models are robust and governed.
* Communication: Translate complex technical findings into clear, actionable recommendations for stakeholders across the business.
Recent projects in the team include:
* A price optimisation agent supporting commercial pricing decisions
* A recommendation engine with associated experimentation / A/B testing
* Natural language search over catalog and content using LLMs / SLMs
* Vision‑based image analysis to enrich product imagery

Hands‑on Programming:
* Strong experience in a hands‑on Data Science role, preferably in e‑commerce, tech platforms, or a technical consultancy.
* Proficient in programming languages such as Python.
* Experience with cloud tools like GCP Vertex AI, BigQuery, or similar.
* Strong experience solving analytical problems using quantitative approaches.
* Understanding of ecosystems, user behaviours, and long‑term product trends.
* Proven track record in leading data‑driven projects from definition to execution, including defining metrics, experiment design, and communicating actionable insights.
* Proven experience in A/B testing, hypothesis testing, and defining success metrics for consumer‑facing products.
* Demonstrated experience (or a strong, informed interest) in integrating LLMs, NLP, or Vector Databases into traditional data science workflows.
* Experience working in a product‑led environment.
* Track record of using data to drive business KPI uplift (e.g., conversion, retention).
* Familiarity with collaborative development practices (peer reviews, boards, sprint planning).
Other desired skills:
* Experience with Learning to Rank (LTR), price elasticity modelling, or multi‑modal search architectures.
* Familiarity with evaluation frameworks for generative AI or non‑deterministic systems.
* Degree in Statistics, Mathematics, Computer Science, or a related quantitative field (Masters/PhD preferred).
