Full Job Description
Overview of the organization:

The COO Enterprise Solution Engineering capability is responsible for the development of best-in-class technology platforms for Operations, including development of an integrated portfolio of Operations tools, end-to-end solution design for large scale transformation initiatives, design governance, and adoption of Generative AI solutions for driving operational efficiencies.

Role:

We are hiring a Full Stack Lead Engineer who can support a critical Cash & Intraday Liquidity Management platform. This platform sits at the intersection of engineering ambition and real-world financial impact - for a wide range of internal and external consumers. This is a rare opportunity for a hands-on engineering professional to own a multi-year technical roadmap, build and scale a world-class global engineering organization, and deliver AI-first, cloud-native systems that operate with the highest standards of availability across multiple geographies and regulatory environments. If you are energized by hard engineering problems, thrive at the intersection of technical depth and organizational scale, and want your work to matter at a global level - this role is built for you.

Responsibilities:
  • Own the end-to-end technical strategy and multi-year roadmap for a foundational cash & intraday liquidity management platform - making architectural decisions that determine how a high-throughput, multi-consumer API ecosystem evolves across global markets.
  • Design and deliver highly available, fault-tolerant distributed systems across multiple geographic regions, with architectures that maintain platform continuity, data sovereignty compliance, and consistent service levels across jurisdictions with differing regulatory requirements.
  • Drive an AI-first engineering culture - embedding LLM tooling into both the platform and the team's day-to-day engineering practices to accelerate delivery velocity and raise the quality bar.
  • Lead, grow, and develop a global engineering organization of engineers, architects and product managers - building a team environment where technical craft, accountability, and continuous improvement are the standard.
  • Stay hands-on in architecture reviews, code quality, and technical decision-making - providing direct engineering guidance on microservices design, cloud-native deployment, distributed systems patterns, and API development.
  • Partner with risk, compliance, and infrastructure teams to embed security controls, disaster recovery planning, and audit-ready practices across all operating regions - ensuring the platform meets regulatory obligations without compromising engineering agility.
  • Translate platform strategy into clear executive communications for senior business and technology leadership, while keeping engineering teams grounded in purpose, priorities, and delivery outcomes.


Required Skills, Knowledge & Experience
  • 6+ years of software engineering expertise designing and operating highly available, multi-region distributed systems - including active-active and active-passive topologies, data residency controls, disaster recovery strategies, and cross-jurisdictional regulatory compliance architecture.
  • Deep hands-on proficiency in Java, Spring Boot, with practical experience building microservices, APIs, and event-driven systems using Apache Kafka, IBM MQ or equivalent high-throughput messaging platforms.
  • Fluency across the full engineering stack - front-end (ReactJS), back-end (Java, Spring), data stores (Oracle, MongoDB), and containerized cloud-native infrastructure (Kubernetes, Docker, OpenShift, public cloud).
  • Expertise in CI/CD, test-driven development, and modern engineering tooling - including JUnit, JMeter, Mockito, Cucumber, Jenkins, and GitHub Actions - applied consistently to maintain engineering quality at scale.
  • Experience in using AI coding assistants such as CoPilot, Devin, Claude Code or equivalent.
  • Strong stakeholder management skills - experience navigating complex, matrixed organizations and driving alignment across business, technology, and operations
  • Demonstrated ability to structure and lead product working groups, driving consensus on requirements and facilitating the development and implementation of processes, data, and system designs.
  • Proven ability to attract, develop, and retain top engineering talent in a competitive market
  • Experience operating in Agile delivery frameworks at enterprise scale, with a bias for continuous delivery and iterative value creation


Education:
  • Bachelor's degree/University degree or equivalent experience
  • Master's degree preferred
