Senior Data Scientist Job at 360 Resourcing Solutions (Chester)

Job Description

The Senior Data Scientist is a hands-on technical role responsible for designing, building, and shipping the machine learning models that drive commercial performance across the group. This role takes business problems through the full lifecycle - framing the problem, exploring the data, building and validating models, and getting them reliably into production. The role combines deep technical delivery with clear communication, partnering with product, commercial, and engineering colleagues to make sure the work is grounded in real outcomes. We are looking for someone technically excellent and commercially aware, who writes high-quality code, makes sound modelling decisions, and helps raise the standard of how the team works.

Job Responsibility

Build & Deliver Impactful Solution: Design, build, and ship machine learning models that address real commercial problems, taking ownership of the work from initial framing through to a validated solution in production
Work closely with product, commercial, and engineering colleagues to scope problems well, contributing technical input early so the team commits to work that is both feasible and valuable
Translate business challenges into clear data science work, defining scope, success measures, and trade-offs in plain language
Contribute to where data science can add the most value next - pricing, personalisation, forecasting, owner and guest experience, and bring strong ideas to how those problems are approached
Collaborate & Lead Technically: Act as a senior technical contributor, setting a high bar for code quality and modelling rigour to help shape how the team approaches its work
Communicate your work clearly: write up model behaviour and results, present in roadmap and review forums, and keep colleagues informed and confident in what the team is delivering
Mentor less experienced data scientists through code review, pairing, and technical guidance, and act as a trusted point of contact for product, engineering, and commercial colleagues working with the team
Run Reliable Models in Production: Keep the models you build running reliably in production: set up monitoring, alerting, and drift detection, track performance, and manage the retraining cadence that keeps them healthy
Work to and help uphold the team’s standards for code review, model documentation, reproducibility, testing, and deployment, so quality stays consistent across the function
Work with data engineering and platform teams on MLOps tooling and infrastructure, and help respond to incidents affecting live models

Requirements

Strong hands-on data science and ML experience, with the ability to design end-to-end models, write production-quality code, and make independent modelling and architecture decisions
Advanced Python and SQL, including pandas, scikit-learn, and XGBoost/LightGBM
Experience in at least two of the following: forecasting, segmentation, recommender systems, ranking, or behavioural modelling
Proven delivery of ML projects end to end, from problem framing and exploratory analysis to production deployment
Ability to translate business problems into well-scoped data science solutions, prioritising commercial impact over technical novelty
Strong communicator, able to explain models and insights to non-technical stakeholders across product, commercial, and engineering teams
Experience deploying and maintaining models (monitoring, retraining, MLOps)
Familiar with modern tooling (cloud ML, experiment tracking, feature stores) and scalable engineering practices

Nice to have

Experience in travel, hospitality, marketplace, or consumer platforms
Familiar with pricing, demand forecasting, recommendations, or CLV modelling
Practical experience with LLMs, agentic AI workflows, or applied generative AI in a production setting
Experience with Microsoft Fabric, Azure ML, or equivalent cloud ML tools (e.g. AWS/ Azure)
Interest in responsible AI, explainability, and governance
