This is a full-time hybrid role based in Dublin, requiring three days per week onsite.

Role:
· Define and drive the North Star architecture for Mastercard’s Customer Acquisition & Engagement technology ecosystem, translating business and product strategy into a scalable technical vision.
· Develop and execute phased architecture roadmaps that move existing platforms toward the target state while clearly defining priorities, dependencies, and technical tradeoffs.
· Lead architecture across large-scale distributed systems, ensuring solutions are scalable, resilient, secure, observable, and optimized for performance and cost.
· Drive the integration and simplification of the MarTech ecosystem, including customer data, identity, audiences, personalization, offers, loyalty, campaign activation, experimentation, and measurement.
· Define enterprise architecture patterns, standards, reusable components, and reference implementations that enable engineering teams to build consistently and efficiently.
· Partner across Product, Engineering, Technology, and business teams to align technical decisions with customer needs, product strategy, and business outcomes.
· Evaluate complex technical challenges, trace customer journeys and data flows across platforms, identify architectural risks, and develop proofs of concept to validate solutions.
· Provide hands-on technical leadership across cloud platforms, APIs, event-driven architectures, data platforms, integration patterns, automation, and Infrastructure as Code.
· Use generative AI and AI-assisted engineering practices to research and challenge designs, accelerate prototyping, improve engineering workflows, and assess implementations against architectural standards.
· Guide architectural decisions from design through production, embedding privacy, consent, security, resilience, performance, scalability, observability, and cost considerations.
· Influence technical and business decisions across the organization, translating complex architecture concepts into clear recommendations for engineering teams, product leaders, and senior executives.
· Mentor architects and engineers, promote strong engineering and architecture practices, and foster cross-functional collaboration while influencing teams without direct authority.
