Senior Machine Learning Scientist

Salary: £61,000 - 101,000 per year

Requirements:

• Strong software engineering experience delivering end-to-end services in production, with ownership for run/support considerations
• Proficiency in Python and modern engineering practices, including clean code, testing, packaging, dependency management, and Git-based workflows
• Hands-on experience with AI deployment patterns and infrastructure, such as Docker, Kubernetes, API-based serving, and batch/stream inference
• Practical MLOps experience, including CI/CD for ML, model packaging and release management, automated validation, monitoring, and lifecycle management
• Working knowledge of ML/DL frameworks and tooling, such as PyTorch, TensorFlow, and the Python ML ecosystem, to collaborate effectively with data scientists and implement inference pipelines
• Experience working with complex, multi-layered datasets, including imbalanced data, and integrating data pipelines into AI services
• Hands-on experience building and deploying web APIs using libraries such as Flask or FastAPI
• Proficiency with database technologies such as SQL Server or Postgres
• Strong stakeholder communication skills, with the ability to explain technical designs, risks, and operational considerations to technical and non-technical audiences
• Good organisational skills and delivery discipline, including prioritisation, time management, and working across multiple initiatives
• Degree in a relevant field or equivalent practical experience, with a Masters preferred
• Model explainability approaches or tools, such as SHAP, where required by the use case and governance expectations

Responsibilities:

• Design, build, deploy, and operate production-grade AI services, including ML and/or GenAI, that are secure, scalable, and reusable across Wholesale use cases
• Productionise PoC and PoV work into hardened solutions with clear non-functional requirements, including performance, resilience, cost, and security, and defined service ownership
• Build and maintain MLOps and LLMOps pipelines, including CI/CD, automated testing, packaging, promotion and rollback, and model/version management, to enable repeatable releases
• Develop reusable engineering assets, such as libraries, templates, reference architectures, and infrastructure-as-code patterns, to reduce technical debt and accelerate delivery
• Implement observability for AI services, including logging, metrics, tracing, model performance monitoring, and quality or drift checks with actionable alerting
• Partner with data scientists, data engineers, platform teams, and governance or risk stakeholders to ensure end-to-end delivery meets control, auditability, and documentation expectations
• Translate business requirements into technical designs and communicate trade-offs and recommendations clearly to technical and non-technical stakeholders
• Contribute to engineering standards and ways of working, including code reviews, design reviews, and documentation, and help uplift team capability through practical coaching
