Senior ML Ops Engineer

Department: Platform Delivery

Employment Type: Permanent - Full Time

Location: London

Description

Key Responsibilities

• Continuously evolve the platform infrastructure powering all AI services (predictive modelling, NLP, knowledge representation, and agentic AI), ensuring reliable, scalable operation across a growing base of local authority clients.
• Deploy and manage ML models via Azure ML endpoints, batch endpoints , and AKS, enabling resilient, secure model hosting that accelerates client onboarding and ensures models remain performant and monitorable throughout their lifecycle.
• Ensure all ML systems are transparent, explainable, and auditable, aligned with Responsible AI principles and UK GDPR; essential where AI outputs inform decisions about vulnerable people in health and social care.
• Design, build, and maintain production-grade orchestration pipelines (Dagster) supporting model training, inference, and retraining, ensuring data from local authority systems is timely, accurate, and fit for purpose before it reaches ML services.
• Contribute to organisation-wide AI capability building, sharing best practice with delivery and consulting teams, advising on technical feasibility, and shaping governance standards as the AI function scales.

• Building and maintaining CI/CD pipelines (Azure DevOps or equivalent) for automated testing, building, and deployment of ML services
• Implementing infrastructure-as-code (Terraform, Bicep or Pulumi)
• Implementing monitoring and observability for production systems, including metrics, altering, logging, and dashboarding (e.g. Prometheus, Grafana)
• Pipeline orchestration using Dagster, Airflow, Prefect, or similar

• Practical experience with model serving infrastructure – batch and/or real-time inference at scale.
• Experience operating multi-tenant systems, particularly scaling infrastructure across multiple clients or business units.
• Practical experience building and serving production-ready, asynchronous APIs for embedding and/or other compute-intensive services.
• Experience setting up, and optimising vector databases, e.g. Qdrant, and integrating with other services
• Proficiency in Python for building high-performance data and model pipelines, with strong software engineering discipline (testing, versioning, CI/CD).
• Deep familiarity with the Azure ecosystem (Azure Kubernetes Service, Azure Container Registry, Azure DevOps, Azure Blob Storage, Azure Monitor, Azure Key Vault).
