Job summary

EY seeks a strategic Platform Architect to shape the AI platform across cloud and hybrid environments. You will own the reference architecture, scale elastic foundations, and drive secure, observable, and cost-efficient production patterns while aligning senior stakeholders on trade-offs.

This high-impact role blends systems thinking with hands-on engineering, guiding teams to deliver reusable production patterns and evidence-driven releases in a global EY Challenger program.

Qualifications

• Bachelor’s Degree in a relevant field of study.
• 9-12+ years of relevant experience.
• Significant experience designing and operating cloud, infrastructure, SRE, or platform capabilities, including production AI workloads.
• A track record of building a shared platform adopted by multiple product teams with measurable improvements in speed, reliability, or cost.
• Deep experience in at least one major cloud and strong judgment about portable patterns for hybrid or multi-cloud constraints.
• Hands-on depth in orchestration, networking, identity, infrastructure as code, delivery automation, APIs, and production observability.
• Experience operating model-serving and AI lifecycle capabilities, including release controls, evaluation, capacity, service objectives, and incident learning.
• Demonstrated ability to make build-versus-buy decisions and explain operational, commercial, and technical consequences.
• Experience leading complex programs, influencing senior stakeholders, and raising engineering capability through mentoring.
• This role requires up to 50% travel and flexibility to go into the office in a hybrid capacity.

Responsibilities

• Set the platform direction. Own the AI platform vision, reference architecture, roadmap, and non-functional standards across cloud, hybrid, and approved edge environments.
• Run the platform as a product. Understand developer needs, define clear service tiers and golden paths, prioritize the roadmap, and measure adoption and time to value.
• Enable portable model access. Design gateways and stable contracts that support model choice, policy-aware routing, resilience, and controlled experimentation without hiding important trade-offs.
• Architect elastic foundations. Shape the compute, storage, and network capabilities needed for AI workloads, balancing performance, regional constraints, resilience, and cost.
• Automate the path to production. Create repeatable delivery patterns that promote code and AI assets together, with progressive release, rollback, and evidence built into the process.
• Define trusted agent runtimes. Establish secure execution patterns for tools, identities, approvals, isolation, recovery, and replay so agent behavior remains controlled and understandable.
• Engineer for reliability. Set service objectives, observability standards, recovery patterns, and resilience exercises that make platform health measurable and operationally useful.
• Make economics visible. Connect usage, performance, and quality signals so teams can improve unit economics without weakening reliability or user outcomes.
• Guide strategic choices. Lead build-versus-buy and portability decisions with engineering, product, security, risk, procurement, and finance partners.
• Build capability. Mentor platform engineers and SREs, strengthen architecture practices, and help teams turn emerging technology into reusable production patterns.
