Position Summary

We are seeking a Senior Enterprise Integration Platform Developer / Technical Lead to design, develop, and support enterprise integration solutions that connect SaaS, cloud, ERP, and internally developed applications.

This is a senior, hands-on technical leadership role responsible for developing integration services, APIs, events, message flows, protocol adapters, and reusable platform capabilities. The successful candidate will independently lead complex integration initiatives from requirements and solution design through development, testing, deployment, production stabilization, and ongoing support.

The role will provide technical direction, establish integration standards, guide application teams onboarding to the enterprise integration platform, mentor developers, and influence platform architecture. The individual will work closely with product, architecture, security, infrastructure, DevOps, business application, and vendor teams to deliver scalable, secure, supportable, and reusable integration solutions.

The position will support Finance and other enterprise application portfolios, including integrations with Oracle ERP and SaaS platforms, while helping advance the organization’s broader cloud, API, event-driven, and Finance transformation objectives.

Troubleshoot complex production issues across APIs, integrations, messaging platforms, databases, cloud services, and dependent applications; perform root-cause analysis and implement permanent corrective actions.
Contribute to CI/CD pipelines, automated testing, deployment automation, monitoring, and platform engineering improvements that increase delivery efficiency and operational reliability.
Serve as a technical leader and subject matter expert by mentoring developers, communicating design decisions and tradeoffs, coordinating delivery across teams, and influencing technical direction.
