• Ensure compliance of solution designs with Mastercard Technology and Security standards and policies.
• Support closely the Engineering Team to progress software through review.
• Collaborate with Engineering and Data Science teams to design and implement MLOps pipelines and feature derivation workflows that enable scalable, secure, and reliable deployment of machine learning models into production.
• Work with platform architects to ensure appropriate infrastructure sizing, deployment strategies, and alignment with enterprise standards for performance, resilience, and cost-efficiency.
• Define and maintain API specifications.
• Assist with architectural design assessments for changes and evolution of FCS products.
• Assist with technology assessments, software selections, and architectural evaluations to ensure alignment with business objectives and technical requirements.
• Circulate architectural designs across cross-functional team leads to support estimations and development processes.
• Design for resilience and reliability of services.
• Take an active role to improve the customer experience of services/applications sold as products or bundled services.
• Drive architectural design, including dependent services, service interactions, and policies.
• Address emerging technical concerns and recommend innovations to enhance market-readiness of specific solutions.
• Present solution designs in review architecture meetings and drive resolutions to enterprise-wide challenges and regulatory needs.
• Develop understanding of end-to-end technical architecture and dependency systems.
• Design for optimal performance and resilience of products.
• Participate in the hybrid work model; based in central London with office attendance in line with Mastercard policy (team days currently Monday and Thursday).
