Job summary

EY invites senior cloud engineers to join Challenger Core, shaping AI-enabled infrastructure that stays secure, observable, and cost-aware across distributed services. You will guide architecture decisions, improve production readiness, and lead cross-team initiatives in a hybrid, travel-ready role.

You will apply AI tools to accelerate infrastructure and automation work, review outcomes, and coach engineers toward durable, impactful solutions that meet service objectives and security

Qualifications

• Bachelor’s Degree in a relevant field of study.
• 9-12+ years of relevant experience.
• Substantial experience designing and operating cloud, infrastructure, platform, or site reliability capabilities in production.
• A record of solving complex distributed-system problems and explaining why the chosen solution will work.
• Hands-on expertise with infrastructure as code, modern runtime platforms, networking, identity, and delivery automation.
• Experience defining service objectives and using observability, capacity planning, and recovery testing to improve live systems.
• Evidence of investigating difficult failures, supporting response, and converting lessons into durable remediation.
• Strong coding skills and the ability to validate AI-generated or otherwise automated engineering output independently.
• Experience mentoring engineers and guiding architecture or readiness decisions without relying on formal delivery ownership.
• This role requires up to 50% travel and flexibility to go into the office in a hybrid capacity.

Responsibilities

• Build shared cloud foundations. Create reusable infrastructure, environment patterns, and deployment automation that help teams start quickly and operate consistently.
• Use AI-assisted engineering responsibly. Apply AI tools to accelerate development and investigation while independently reviewing, debugging, testing, and validating the resulting code.
• Guide complex designs. Review architectures, migrations, and releases where trade-offs affect reliability, security, performance, cost, or multiple use cases.
• Strengthen production readiness. Define the evidence required before launch and identify what must change when a service is not ready to operate reliably.
• Set reliability practices. Establish service objectives, observability standards, actionable alerts, and operational reviews that connect system behavior to user outcomes.
• Make cost and capacity visible. Test workload assumptions and use performance, consumption, and demand evidence to guide scaling and architecture decisions.
• Resolve difficult failures. Lead deep investigation across distributed services and integrations, verify root causes against system evidence, and test durable fixes.
• Prove resilience. Design performance tests, failure simulations, recovery exercises, and rollback paths that show how services behave under stress.
• Turn lessons into reusable capabilities. Publish tested reference implementations, guidance, and runbooks that state both the intended use and important limitations.
• Raise engineering capability. Coach engineers, challenge assumptions constructively, and transition proven capabilities to ongoing owners with clear operating responsibilities.
