Software Developer, Market Data Interfaces (MDI)

MDI team is seeking a Software Developer to join and contribute across the MDI platform, Alpha Data Platform (ADP) microservices, and quality automation. This role is suited for an engineer who is comfortable working across a large enterprise Java codebase and modern cloud-native services, while also taking strong ownership of automated quality, reliability, and production support. The successful candidate will help design, build, test, troubleshoot, and evolve real-time and batch processing solutions that support market data, reference data, and downstream integration workflows in a regulated financial technology environment.

This engineer will work as a member of an Agile Scrum team, partnering closely with product owners, QA, support, platform teams, and peer development teams. The role requires equal strength in software design, hands-on implementation, defect investigation, and test automation. It is not a pure feature-development role; it also includes operational ownership, cross-team collaboration, and continuous improvement of engineering practices.

Key Responsibilities

• Design, develop, enhance, and maintain RTAPI components and related backend services used for real-time and batch data processing.
• Build and support ADP microservices using event-driven and service-oriented patterns.
• Implement user stories and defect fixes that meet acceptance criteria and Definition of Done without introducing unnecessary technical debt.
• Troubleshoot complex functional and production issues across distributed services, legacy modules, and integration layers.
• Perform root cause analysis for defects impacting internal users, support teams, and downstream systems.
• Write clean, maintainable, well-tested Java code with strong attention to reliability, performance, and supportability.
• Create and maintain automated unit, integration, functional, and regression tests.
• Improve QA automation coverage for APIs, event-driven flows, database-backed logic, and vendor/provider integrations.
• Validate business logic involving data transformations, reference data workflows, and vendor feed processing.
• Participate in backlog grooming, estimation, sprint planning, retrospectives, and technical design discussions.
• Review code, test plans, automation coverage, and design changes from peers.
• Contribute to build, deployment, and release readiness across shared environments.
• Identify risks, dependencies, and blockers early, and work across teams to resolve them.
• Mentor junior engineers and help raise engineering standards across the team.
• Contribute to documentation, test strategy, support runbooks, and long-term platform improvements.

What You Will Own

• Delivery of new RTAPI and microservice capabilities from design through automated validation
• Stability and supportability of critical data-processing workflows
• High-quality automation for unit, integration, and regression coverage
• Investigation and resolution of complex issues affecting production or client-facing workflows
• Technical leadership within the Scrum team, including code quality, design quality, and execution discipline
