Reporting to the Director of Engineering Platforms & AI Architecture, the role turns fast-moving AI capabilities into scalable, secure and supportable target architectures, roadmaps and reusable patterns.\nThe remit covers AI applied to silicon design and verification, software development, CI/CD, developer platforms, technical computing including HPC, EDA, engineering data and knowledge, and the CLI, IDE, API, chat and batch interfaces engineers use. This role determines what can reuse common AI foundations, what needs adaptation and where engineering-specific capabilities are justified.\nThis is a senior individual contributor role, leading through expertise and influence. It partners with the Senior Principal Bus App AI Architect and Director Eng Platform Architecture so common principles and controls work with specialist Engineering patterns. Product, platform, delivery and service owners remain accountable for implementation and operation.\nResponsibilities:\nDefine and maintain the target architecture and roadmaps for AI-enabled engineering across software development, build, verification, test, design and engineering operations.\nTurn Engineering priorities and external market insight into clear choices on build, buy, reuse, platform fit and lifecycle, reducing fragmentation and avoidable vendor dependency.\nCreate practical patterns for engineering agents, retrieval, model access, tool use, orchestration, context, evaluation, observability and production support.\nDefine supported integration patterns across source control, CI/CD, artefact management, IDEs, command-line tools, APIs, schedulers, technical compute and specialist engineering platforms.\nSet architecture for identity propagation, secrets, permissions, tool and command execution, human approval, traceability, failure handling and safe shutdown.\nShape how AI accesses source code, specifications, build and verification results, design artefacts, telemetry and engineering knowledge while protecting provenance, quality, confidentiality and intellectual property.\nLead significant Engineering AI design decisions and contribute specialist expertise to design authority, balancing scale, latency, concurrency, resilience, cost and supportability from experiment through production.\nPartner with the Senior Principal Bus App AI Architect, Platform Architecture, Data, Security, Engineering and service leaders, and develop capability through mentoring and reusable guidance.\nRequired Skills and Experience:\nA record of leading architecture for complex engineering platforms, developer environments or technical-computing ecosystems at scale.\nExperience designing production AI solutions, including generative AI, agentic systems, retrieval-augmented generation, model integration and evaluation.\nStrong architecture knowledge across source control, CI/CD, artefact management, build systems, developer tooling, APIs, events, IDE and command-line workflows.\nExperience designing for demanding distributed or compute-intensive workloads, including throughput, latency, concurrency, scheduling, capacity, resilience and cost.\nKnowledge of identity, authorisation, secrets, privileged execution, software supply-chain controls, auditability and safe failure for AI-enabled workflows.\nExperience defining target architectures, reference patterns and non-functional requirements, and guiding services from experimentation into reliable production operation.\nThe ability to influence senior Engineering and technology leaders, translate between specialists and enterprise teams, and build commitment without reporting-line authority.\n“Nice To Have” Skills and Experience:\nExperience with semiconductor or SoC development, EDA, verification, simulation or related engineering workflows.\nExperience designing agents that interact with code, tools, jobs or technical workflows, including tool-protocol ecosystems.\nContribution to engineering or AI architecture communities, standards, research, open source or technology partnerships.\nIn Return:\nJoining Arm means being part of a world-class team that is high-reaching and determined to achieve outstanding results.
