Senior AI Platform Engineer

We are building a central AI control plane to support the safe, scalable, and efficient use of AI across Arm’s engineering teams.

This hands-on platform engineering role will help deliver and own the runtime platforms that make AI services reliable, secure, observable and supportable at Arm scale. You will work across Kubernetes, cloud, identity, secrets, networking, telemetry, incident management and automation to provide the production foundation for Arm’s AI platform.

You will initially contribute in three key areas:

Production AI runtime platforms:

• Build/deploy and operate the infrastructure for centrally hosted AI platform services, including MCP server infrastructure, model gateway services and supporting control-plane components.
• Design runtime patterns for isolation, scalability, secure execution, capacity management and cost-aware operation.
• Automate provisioning, configuration, upgrades and lifecycle management using infrastructure-as-code and GitOps patterns.

Reliability, observability and support:

• Define and implement service-level indicators, service-level objectives, alerting, dashboards, runbooks and support workflows.
• Incident response, post-incident review and vendor outage handling for AI services embedded in engineering workflows.
• Build telemetry that helps Arm understand AI platform health, usage, performance, cost and operational risk.

Secure operations by default:

• Ensure platform components meet production readiness, security and compliance expectations.
• Help make secure AI usage the default by providing reliable paved paths rather than manual or fragmented infrastructure., * Build, operate and continuously improve the production infrastructure for Arm’s AI platform services, using both custom and third party solutions.
• Own reliability, scalability, monitoring, alerting, incident response, runbooks and operational readiness for AI platform components.
• Develop automation for provisioning, deployment, configuration, backup, recovery, patching, upgrades and lifecycle management.
• Implement secure runtime patterns, including workload isolation, secrets management, identity integration, network controls and auditability.
• Participate in production support and our paid on-call rota for high impact incident response., At Arm, we want to build extraordinary teams.

Details of what this means for each role will be shared upon application. In some cases, the flexibility we can offer is limited by local legal, regulatory, tax, or other considerations, and where this is the case, we will collaborate with you to find the best solution. Please talk to us to find out more about what this could look like for you.

• Familiarity with AI platform concepts such as model routing, MCP servers, agentic workflows, RAG systems or LLM observability.
• Strong experience deploying and operating production infrastructure or platform services in a Linux-based environment using Kubernetes, containers, cloud or private-cloud platforms, infrastructure-as-code and CI/CD/GitOps tooling.
• Strong automation and scripting skills, for example Terraform, Go, Python or similar.
• Experience with incident management, problem management, demand forecasting, and production readiness practices.
• Good understanding of security fundamentals for production platforms, including identity, secrets, access control, network segmentation, vulnerability management and audit logging.
