The role will also guide the integration practice by defining standards, mentoring other engineers, and ensuring alignment with broader enterprise architecture and governance.

• Architect and lead integration solutions – Take ownership of end-to-end integration solution architecture (including OIC, MuleSoft, hybrid cloud/on-premise), evaluate design alternatives, make technology decisions, ensure non-functional requirements (performance, scalability, security, monitoring) are met.
• Design and develop high-complexity integrations – Build, configure, test, deploy, and support integrations, APIs, event-driven flows and orchestrations using OIC and MuleSoft; collaborate closely with application owners, architects and business analysts to translate requirements into robust integration solutions.
• Define and enforce integration standards & best practices – Establish and maintain integration patterns, reusable artifacts (connectors, templates, APIs), governance model, CI/CD pipeline, monitoring/alerting and documentation standards for the integration practice.
• Operate and optimize integration platforms – Oversee runtime health of the integration ecosystems (OIC, MuleSoft), monitor performance/throughput, troubleshoot incidents, lead root-cause analysis, implement operational improvements and ensure high availability and reliability of integration services.
• Mentor and collaborate with team members and stakeholders – Serve as a subject-matter expert; provide guidance, code reviews, training, and mentorship to more junior integration developers; work cross-functionally with architecture, security, DevOps, application teams and business stakeholders to align integration strategy with enterprise goals.

• Bachelor’s degree in Computer Science, Software Engineering, Information Systems, or a related field (or equivalent practical experience).
• Typically 10+ years of professional experience in enterprise integration development and architecture (or equivalent mix of development + architecture).
• Hands-on experience with either Oracle Integration Cloud (OIC) or MuleSoft Anypoint Platform (or at minimum one plus strong transferable skills) in high-volume, enterprise deployments.
• Proven track record in designing, building and operating complex integrations across cloud and on-premise systems (ERP, CRM, HCM, data platforms).
