You'll collaborate with engineering, architecture, product, and data teams to design, define, and deliver APIs and data solutions that form the backbone of StoneX's global connectivity and market intelligence capabilities.

If you thrive at the intersection of business and technology, translating complex integration and data requirements into scalable solutions, this role is for you.

Primary Duties will include:

• Requirements Gathering & Analysis:

• Collaborate with Product Owners, Architects, Developers, and QA teams, to elicit and document clear, comprehensive business and technical requirements for APIs and middleware services.

• Translate integration needs from multiple systems into cohesive API specifications and reusable service definitions.

• Conduct gap analyses across existing APIs to identify areas for consolidation, standardization, or modernization.

• Technical Analysis & Troubleshooting:

• Analyze data flows, payloads, and service interactions to diagnose issues and recommend solutions.

• Collaborate with engineering teams to resolve technical challenges related to API integrations, caching, or data enrichment.

• Evaluate and recommend best practices in API design, versioning, and governance.

• Delivery Tracking & Backlog Management:

• Own and maintain delivery tracking across agreed scope, dependencies, risks, and milestones, ensuring stakeholders have clear visibility of progress and blockers.

• Manage and refine the team backlog in partnership with Product Owners and engineering leads, ensuring items are well defined, prioritized, and ready for delivery.

• Translate business priorities into actionable epics, user stories, acceptance criteria, and delivery plans that support predictable execution.

• Facilitate follow-ups on open decisions, requirements gaps, and cross-team dependencies to keep delivery moving and reduce ambiguity.

• Documentation & Modelling:

• Create and maintain detailed documentation including API contracts, data models, and process flows.

• Develop and maintain documentation supporting public and partner-facing APIs, ensuring clarity, security, and ease of adoption.

• Prepare training and onboarding materials for internal users and API consumers as needed.

• Agile Development Collaboration:

• Facilitate Agile ceremonies including sprint planning, stand-ups, backlog refinement, sprint reviews, and retrospectives.

• Partner with Product Owners to maintain and prioritize API development backlogs, balancing new capabilities, stability, and technical debt.

• Support the definition of API lifecycle processes–discovery, onboarding, change management, and deprecation.

• Integration & Testing Support:

• Define and validate integration points across internal systems and external partner channels.

• Support QA teams in designing test scenarios for API validation, contract testing, and performance benchmarking.

• Facilitate UAT and API consumer testing, ensuring alignment with business requirements and developer experience standards.

• Continuous Improvement:

• Identify opportunities to improve API reusability, performance, and developer experience.

• Contribute to defining API governance frameworks and standards for documentation, security, and version control.

• Provide insights into emerging API technologies, middleware tools, and architectural patterns such as event-driven design and microservices.

Qualifications Qualifications:

• 5+ years of Business Analyst experience in a technology or integration-focused environment (API, middleware, data services).
• Strong understanding of API design principles (REST, gRPC, event streaming), data mapping, service-oriented architecture, and data analysis (eg, SQL).
• Proficiency in Agile methodologies (Scrum, Kanban) and cross-functional team collaboration.
• Experience facilitating Agile ceremonies and coordinating delivery across cross-functional teams.
• Hands-on experience with tools such as Swagger/OpenAPI, Postman, JIRA, Confluence, or Azure DevOps.
• Excellent analytical, communication, and documentation abilities.
• Ability to produce clear and detailed documentation, including user stories, process flows, and technical specifications.
• Preferred: experience defining public or partner-facing APIs, API gateways, and developer portals.
