ML Ops Engineer

ML Ops Engineer

London

Were hiring an ML Ops Engineer to build and operate the platform capabilities that take machine-learning models from experimentation into reliable production services.

Youll own the automation deployment observability and operational controls around the ML lifecycle working closely with research engineers software engineers platform teams and product teams.

This is not a research role. It is a hands-on engineering role focused on making ML systems reproducible scalable secure and dependable from model packaging and release through to serving monitoring retraining and incident response.

What youll work on

ML lifecycle and platform engineering

• Build repeatable workflows for model training validation promotion deployment and retraining.
• Productionise models through packaging versioning model registry integration deployment automation and safe rollback.
• Design CI/CD pipelines for ML systems including automated testing validation release controls and environment promotion.
• Manage experiment tracking model metadata and reproducibility across research and production.
• Build reusable tooling and platform capabilities that support multiple models and engineering teams.

Model serving and observability

• Deploy and operate batch and online inference services in containerised cloud environments.
• Define and meet availability latency throughput and recovery objectives for ML services.
• Monitor service health infrastructure data-quality signals data drift prediction drift and model performance decay.
• Establish dashboards alerting and operational runbooks so failures are detected and resolved quickly.
• Support automated or controlled retraining model promotion rollback and model retirement.
• Debug production issues across model application infrastructure and critical data-dependency layers.

Reliability security and engineering quality

• Improve system robustness scalability and cost efficiency through automation observability and infrastructure as code.
• Write production-grade Python for long-running services deployment tooling and ML workflows.
• Establish testing validation release and incident-management practices for ML systems.
• Collaborate with platform security and data engineering teams on reliable model inputs access controls secrets resilience and compliance.
• Make explicit trade-offs between research flexibility delivery speed operational risk and production stability.

Additional responsibilities

• Maintain personal/professional development to meet the changing demands of the role including all relevant regulatory and legislative training
• When dealing with all customers clients or colleagues ensure that we provide a clear fair and consistent high quality service that presents a professional and positive image of CMC Markets
• Take all reasonable steps to ensure appropriate confidentiality
• Undertake such other duties training and/or hours of work as may be reasonably required and which are consistent with the general level of responsibility of this role

KEY SKILLS AND EXPERIENCE

• 37 years professional experience in MLOps ML platform engineering ML infrastructure backend engineering DevOps or SRE.
• Strong production Python skills including clean APIs testing performance awareness and maintainable services.
• Experience deploying serving and operating machine-learning models in production environments.
• Practical understanding of the ML lifecycle including training validation inference model release monitoring and retraining.
• Experience designing CI/CD workflows and release processes for ML or other production software systems.
• Hands-on experience with at least one workflow or orchestration system used for ML training validation or deployment.
• Comfort working with cloud infrastructure containers infrastructure as code and service networking.
• Strong understanding of observability monitoring alerting incident response and common failure modes in ML systems.
• Ability to reason about system design reliability and operational trade-offsnot just individual tools.
• Clear communication skills and the ability to work effectively with research engineering platform security and product teams.

Nice to have

• Prior ownership of model monitoring drift detection or automated retraining.
• Familiarity with model registries feature stores and offline/online feature-consistency challenges.
• Experience supporting multiple models services or teams on a shared ML platform.
• Exposure to regulated or high-reliability production environments.
• Experience with PyTorch or similar ML frameworks and model-serving technologies.

Technology environment

Language: Python

ML tooling: PyTorch or similar frameworks experiment tracking and model registries

Workflow orchestration: ML workflows for training validation deployment and retraining

Deployment: Containers model-serving frameworks and infrastructure as code

Observability: Metrics logging tracing alerting and monitoring across model service and platform layers

Cloud: Managed compute storage and networking with a provider-agnostic mindset

The technology stack will evolve. We value engineers who understand why systems are designed in particular ways and can adapt as requirements and tools change.

Why this role matters

Machine-learning models only create value when they are correct observable and dependable in production. This role is responsible for making that happen.

Youll reduce the gap between promising experiments and production systems that can be trusted by downstream products and customers. Your work will improve the reliability speed and scalability of the ML platform across the organisation.

If you care about operational clarity robust engineering and building ML systems that do not silently fail this role gives you direct leverage over the success of our machine-learning capabilities.
