"Nice To Have" Skills and Experience: * Experience operating internal developer platforms, AI platforms, model gateways, MCP infrastructure or other shared engineering platforms. * Experience with service mesh, policy-as-code, workload identity, sandboxing, secure runtime environments or multi-tenant platform designs. * Experience with regulated or security-sensitive engineering environments. * Working knowledge of Open AI tools, products and APIs! ## Description 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, technical leadership, platform engineering role will help direct and own delivery of 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. Participate in production support and our paid on-call rota for high impact incident response. 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., * Technical leadership - this role will become a recognised expert and lead engineer on our AI platform's technology stack. * 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. * Contribute towards platform roadmap planning and prioritisation. ## Related Videos - [Docker network without Docker](https://www.wearedevelopers.com/videos/1418-docker-network-without-docker) - [Rate-limiting using eBPF and Istio: How to protect your SaaS customers from themselves](https://www.wearedevelopers.com/videos/100220-rate-limiting-using-ebpf-and-istio-how-to-protect-your-saas-customers-from-themselves) - [Go with the Flow: Stop the Leaks Before Your Memory's a Waterfall!](https://www.wearedevelopers.com/videos/100073-go-with-the-flow-stop-the-leaks-before-your-memory-s-a-waterfall) - [AI-Augmented DevOps with Platform Engineering](https://www.wearedevelopers.com/videos/1614-ai-augmented-devops-with-platform-engineering) - [Docker exec without Docker](https://www.wearedevelopers.com/videos/1094-docker-exec-without-docker) - [Get started with securing your cloud-native Java microservices applications](https://www.wearedevelopers.com/videos/123-get-started-with-securing-your-cloud-native-java-microservices-applications) ## Related Articles - [MLOps And AI Driven Development](https://www.wearedevelopers.com/magazine/82-mlops-and-ai-driven-development) - [Stephan Gillich - Bringing AI Everywhere](https://www.wearedevelopers.com/magazine/489-stephan-gillich-bringing-ai-everywhere) - [Navigating the AI Shift](https://www.wearedevelopers.com/magazine/629-navigating-the-ai-shift) - [From Prototype to Production: Build AI Agents with This Free 4-Course Learning Path](https://www.wearedevelopers.com/magazine/655-from-prototype-to-production-build-ai-agents-with-this-free-4-course-learning-path) - [How to Become an AI Engineer](https://www.wearedevelopers.com/magazine/331-how-to-become-an-ai-engineer) - [Got AI ideas but no money?
