The Lead Software Integration Engineer is responsible for enabling reliable, secure, and scalable integrations across HR platforms (including Workday) and enterprise systems while supporting predictable, high-quality software releases.
This role combines systems integration expertise, technical leadership, release governance, and Agile execution to coordinate platform changes, application interfaces, and cross-system dependencies across complex enterprise environments. The position requires strong knowledge of software development lifecycle practices, integration architecture, API-based services, testing strategies, and production support to ensure stable and effective business solutions.
Overview
Mastercard delivers change across enterprise platforms through a continuous flow of platform enhancements, modernization initiatives, and feature delivery. These changes must be coordinated carefully to ensure stable, compliant, and well-governed production releases.
As a Lead Software Integration Engineer (Release Management), you will provide end-to-end release governance and coordination, ensuring that requirements, dependencies, priorities, architecture considerations, and change controls are aligned across teams before changes move into production. You will work closely with Product Owners, engineering teams, platform partners, and architecture/governance forums to drive disciplined and predictable release execution, while supporting platform modernization and upgrading initiatives across HR systems.
Role
In this role, you will:

• Support reprioritization of work based on release readiness, dependencies, and business priorities
• Maintain a single, integrated view of release scope, including platform changes, application updates, and shared services
• Facilitate release-level and Agile execution activities such as dependency syncs, readiness reviews, and milestone checkpoints
• Coordinate change management activities, including preparation for CAB reviews and approvals
Technology Governance & Architecture Alignment
• Participate in technology governance forums and architecture discussions to ensure release alignment with enterprise standards and long-term platform strategy
• Contribute to solution design and architecture decision-making, particularly where release sequencing and dependencies impact design choices
• Drive visibility into interdependencies across platform upgrades, integrations, and shared services
• Facilitate trade-off discussions across teams and stakeholders to balance delivery timelines, technical constraints, and business priorities
• Ensure alignment between release plans, architecture decisions, and platform roadmaps
• Provide clear visibility into release status, risks, and dependencies for stakeholders and leadership
Platform Modernization & Technical Leadership

• Provide broad technical leadership across enterprise systems, integrations, and release strategy
• Drive continuous improvement of release governance, change management, and execution practices
Systems Integration & Solution Delivery
• Collaborate with engineering, product, architecture, and operations teams to deliver integration solutions and system releases across cloud and on-premises environments.
• Manage cross-system dependencies, interfaces, data flows, and release schedules to ensure successful end-to-end delivery, deployment readiness, and operational stability.
• Provide technical leadership for integration initiatives while driving release planning, risk management, change coordination, and governance processes across multiple platforms.
API & Web Services Management
• Support the design, implementation, and ongoing maintenance of API-based integrations and web services while coordinating release activities across interconnected applications and platforms.
• Establish and promote enterprise standards, best practices, and governance for APIs, integrations, release controls, change management, and deployment processes.
• Evaluate the impact of application, infrastructure, and platform changes on interfaces and integrations, proactively managing risks and ensuring continuity of service throughout the release lifecycle.
Integration Testing & Quality Assurance
• Coordinate integration testing activities across applications, platforms, and release cycles to validate interfaces, data transformations, workflows, and dependent systems.
• Define and support testing strategies, test plans, and quality controls to ensure production readiness for integrations and platform enhancements.
• Partner with engineering teams to establish quality gates and validation checkpoints that reduce risk and improve release outcomes.
Troubleshooting & Operational Excellence
• Support investigation and resolution of complex integration, release, and production issues through structured root-cause analysis and corrective action planning.
• Monitor integration health and deployment outcomes, identifying opportunities to improve reliability, resiliency, and operational performance.
• Drive continuous improvement initiatives focused on improving integration support processes, release quality, and platform stability.
