Senior Data Scientist

As a Senior Data Scientist - Data & AI at Strolll, you will play a crucial role in understanding our Strolll Augmented Reality (AR) software solution application derived data including assessment and game metrics, device telemetry data. Your mission is to realise cutting-edge data that will make Strolll the most used rehabilitation software in the world.

You will be an integral part of our Data & AI team, working closely with our immediate team of engineers focused on health algorithms and assessments, as well as the broader AR platform engineering, design, and Quality Assurance, clinical, and science teams.

Our AR solution is multi-user and requires a physical space, therefore play-tests and feature evaluation requires a controlled physical environment. This role can be hybrid with a portion of your time working onsite in our dedicated office space, with the remainder from home, or fully remote for qualified candidates. You will need to be able travel to the company HQ in Stafford, UK regularly.

This role reports to the VP - Data & AI., * Advanced Data Analytics Expertise: Leverage deep experience with an analytics stack - such as Azure Synapse Analytics, Azure Databricks, Azure Data Lake, and Azure Machine Learning - to design and implement scalable, secure, and cost-effective analytical solutions.

• Insight-Driven Problem Solver: Thrive on solving complex analytical challenges - from hypothesis generation and data exploration to statistical inference and model deployment. Architect robust solutions that support clinical research, operational intelligence, and product innovation.
• Applied Statistical Modelling & Experimentation: Design and execute rigorous statistical analyses, A/B tests, and causal inference studies. Translate complex data into actionable insights using techniques such as regression, classification, time series forecasting, and Bayesian modelling.
• Build Analytical Data Products: Deliver high-quality, production-grade analytical outputs - including dashboards, curated datasets, and model-driven insights - that power clinical decision-making, product development, and strategic planning. Ensure outputs are interpretable, reproducible, and aligned with stakeholder needs.
• Version Control & Collaborative Development: Proficient in Git and Azure DevOps for collaborative analytics development. Comfortable with peer review workflows, CI/CD pipelines, and automated testing of analytical code using tools like pytest, Great Expectations, and dbt.
• Ensure Data Integrity & Analytical Quality: Strong skills in debugging data issues and validating analytical outputs. Use data observability tools and statistical diagnostics to ensure accuracy, reliability, and reproducibility across the analytics lifecycle.
• Optimize for Performance & Impact: Analyze and optimize analytical workflows for efficiency, scalability, and stakeholder impact. Tune Spark jobs, optimize SQL queries, and streamline model training and inference in Azure environments.
• Cross-Functional Collaboration: Partner with clinical, scientific, product, and engineering teams to understand domain-specific challenges and translate them into data science solutions. Collaborate with ML engineers and data engineers to ensure data readiness and model deployment. Contribute to patents and publications where applicable.
• Growth & Thought Leadership: Continuously expand expertise in data science, cloud-native analytics, and responsible AI. Share knowledge through mentorship, internal talks, and contributions to technical reviews and research efforts.

Required:
