Lorien; Greater London; On-site; GBP 90,000 - 135,000; Full time

Job summary

Lorien is seeking a senior Lead Platform Engineer to design, build, and operate an MLOps platform that enables AI teams to deploy ML workloads in production. The role emphasizes hands-on technical leadership rather than people management.

You’ll layer real MLOps capabilities on top of Kubernetes, creating a platform that is usable, well-documented, and trusted in live environments. Expect close collaboration with data scientists and ML engineers.

Qualifications

• Strong background as a Senior or Lead Platform Engineer/DevOps Engineer.
• Deep, hands-on experience building and operating Kubernetes-based platforms.
• Strong practical experience with Helm and Infrastructure as Code (eg Terraform).
• Proven experience extending Kubernetes with higher-level platforms and services, not treating it as the finished product.
• Strong understanding of operational fundamentals: monitoring, logging, incident response, reliability, and maintenance.
• Comfortable working directly with engineers and data scientists to support real production workloads.

Responsibilities

• Provide technical leadership across platform, DevOps, and MLOps activities.
• Design, build, and operate a Kubernetes-based MLOps platform supporting the full model life cycle.
• Implement and run MLOps tooling that enables teams to experiment, package, version, and deploy models; run scalable inference and LLM workloads.
• Build and operate model serving and inference platforms within Kubernetes environments.
• Work closely with data scientists and ML engineers to ensure the platform is usable and well-documented.
• Own platform operability, reliability, security, and supportability in production.
• Troubleshoot complex issues across Kubernetes, platform services, and MLOps layers.
• Contribute to architectural decisions while staying hands-on with delivery.
