## Description

We are looking for a Senior Data Scientist who combines deep machine learning expertise with strong software engineering subject area to design, build, and deploy production-grade ML and AI systems.
This role goes beyond traditional ML engineering. You will apply machine learning science as a core field - developing novel algorithms and models that are not only experimentally validated but architected and deployed as scalable, reliable products. Whether it's advancing NLP, optimisation, simulation, or generative AI, you will deliver solutions that transition seamlessly from research to production and create measurable value.
You will work as part of a cross-disciplinary team alongside data scientists, software engineers, data engineers, and domain authorities - translating complex scientific and business problems into deployable ML products., * Design, build, and maintain scalable, production-grade machine learning systems and pipelines using modern engineering practices (CI/CD, testing, monitoring, observability).

 * Apply machine learning science to develop novel algorithms and models that are deployed as reliable, scalable products - not limited to experimentation but extending through to production delivery and operational use.
 * Build impactful ML products demonstrating statistical modelling, deep learning, and AI techniques across operational, scientific, and R&D domains.
 * Translate complex scientific and business problems into well-scoped ML solutions, delivering actionable insights and deployable capabilities.
 * Architect and optimise ML systems for performance, scalability, and reliability in production environments.
 * Collaborate closely with data scientists, data engineers, software engineers, and domain authorities as part of cross-disciplinary teams.
 * Adhere to and advocate for engineering and data science guidelines (technical design, design reviews, unit testing, monitoring & alerting, code reviews, documentation).
 * Present technical results, trade-offs, and product outcomes to peers and senior partners.
 * Actively supply to improving developer velocity, engineering standards, and shared tooling.
 * Mentor junior team members and chip in to the technical growth of the wider team.
