At EY FSO Technology Consulting, you will collaborate with top-tier professionals to tackle the most intricate challenges in the financial services sector in Ireland. Our mission is to shape a progressive future for financial services in Ireland, and your expertise is the key.

As a member of our Technology Consulting Team, you will be part of dynamic group known for their exceptional performance and dedication to client service. You will have the opportunity to empower organizations to expand, innovate, and enhance their operational efficiency. Your contribution will be instrumental in our collective goal of creating a better working world.

The Engineering Lead (Director) is a hands-on senior engineering and solution architecture leader within EY FSO Technology Consulting. The role has end-to-end technical accountability for the architecture, build, deployment, operation, security, resilience, and continuous improvement of complex client platforms.

This is not solely a programme-management or governance position. The successful candidate must remain technically current and be capable of contributing directly through production-grade coding, prototyping, code and pull-request reviews, solution design, architecture decision-making, performance analysis, and diagnosis of critical production issues.

The Engineering Lead will act as the principal technical authority for assigned engagements: translating business and non-functional requirements into implementable architectures, setting engineering standards and guardrails, making, and defending technology trade-offs, and ensuring teams deliver secure, scalable, resilient, observable, and cost-effective solutions. The role will also lead the practical adoption of AI-assisted and agent-enabled engineering, with appropriate evaluation, governance, security, privacy, and human oversight.

Your key responsibilities

Engineering Leadership & Delivery

• Hold end-to-end technical accountability across the full engineering lifecycle: discover, design, build, test, deploy, run, support, and continuously improve.
• Remain hands-on by writing or materially contributing to production-quality code, developing prototypes and reference implementations, reviewing pull requests, debugging complex defects, and supporting critical production incidents.
• Lead engineering delivery across multiple teams, ensuring solutions meet agreed functional and non-functional requirements for security, resilience, scalability, performance, operability, accessibility, compliance, and cost.
• Set and enforce engineering standards for source control, branching, coding, automated testing, quality gates, release management, documentation, and operational readiness.
• Use measurable engineering outcomes—including deployment frequency, lead time, change-failure rate, recovery time, defect escape, reliability, and developer productivity—to drive continuous improvement.
• Intervene directly when architecture, code quality, delivery risk, or production stability falls below the required standard.

Solution Architecture and Technical Authority

• Own end-to-end solution architecture and translate business, functional, regulatory, and non-functional requirements into coherent technical designs and delivery roadmaps.
• Produce and maintain architecture diagrams, technical specifications, interface contracts, threat models, architecture decision records, and implementation guidance.
• Make authoritative technology-selection, build-versus-buy, integration, data, deployment, and operating-model decisions, clearly documenting trade-offs, and consequences.
• Lead architecture and design reviews, approve or reject material technical approaches, govern implementation conformance, and arbitrate complex decisions across engineering, security, data, operations, and enterprise architecture stakeholders.
• Design for scalability, availability, resilience, recoverability, performance, security, privacy, observability, operability, maintainability, and cloud cost efficiency.
• Own the technical-debt strategy and ensure architecture evolves pragmatically as delivery and production evidence emerges.

Platform and Cloud Engineering

• Lead the architecture, engineering, and operation of cloud-native and hybrid platforms across AWS, Azure, and enterprise environments.
• Design and implement cloud foundations including landing zones, account or subscription structures, identity and access management, networking, connectivity, policy guardrails, backup, disaster recovery, and regional resilience.
• Require Infrastructure as Code and automated configuration management, using technologies such as Terraform, Bicep, CloudFormation, or equivalent.
• Lead production implementation of container platforms, including Kubernetes or OpenShift workload design, Helm-based packaging, networking, ingress, secrets, autoscaling, policy enforcement, and troubleshooting.
• Establish GitOps delivery, reusable platform services, internal developer platforms, self-service capabilities, and secure paved roads that improve developer experience and reduce cognitive load.
• Apply FinOps principles through architecture choices, demand management, tagging, observability, rightsizing, and cost optimisation.

DevSecOps and Engineering Excellence

• Design and govern CI/CD and GitOps pipelines incorporating automated unit, integration, contract, end-to-end, performance, resilience, and security testing.
• Embed secure-by-design practices including threat modelling, OWASP controls, secrets and key management, software-composition analysis, dependency governance, static and dynamic security testing, software supply-chain controls, vulnerability remediation, and policy as code.
• Establish release-safety mechanisms including feature flags, progressive delivery, rollback, environment promotion, and evidence-based deployment approvals.
• Define and implement observability standards covering logs, metrics, traces, dashboards, alerting, service-level indicators, service-level objectives, and error budgets.
• Lead major-incident technical response, root-cause analysis, remediation tracking, runbook development, resilience testing, disaster-recovery exercises, and operational-readiness reviews.

Team Leadership Capability Development

• Lead, mentor, and develop engineering leads, architects, and senior engineers.
• Build high-performing, accountable engineering teams with a strong delivery culture.
• Support recruitment, technical interviews, succession planning, and capability development across the engineering function.

Client Engagement and Advisory

• Act as the principal technical advisor and escalation point for client stakeholders, providing clear, practical, and evidence-based guidance.
• Translate business objectives and regulatory constraints into technical options, consequences, costs, risks, and delivery recommendations.
• Present and defend architecture and engineering decisions to executive, architecture, risk, security, operations, and engineering forums.
• Partner with programme leadership while retaining independent accountability for technical integrity, engineering quality, and production readiness.

Growth and Pursuit Support

• Contribute to proposals and client opportunities through technical solution design, estimation, and delivery input.
• Provide engineering credibility in client discussions without holding primary responsibility for sales.
