Senior Java / B2B Integration Engineer
About The Position
The Senior Java / B2B Integration Engineer sets the technical direction for B2B integration delivery. This hands-on senior role combines deep Java and B2B engineering skills with technical leadership and governance. The engineer defines integration patterns and standards, provides architecture guidance, and reviews development work performed by the offshore team to ensure alignment with client architecture and standards. The role develops and maintains reusable patterns for B2B/EDI, API, and file-based flows; establishes standards for coding, design, error handling, observability, and security; and creates reference implementations and accelerators. It provides solution design guidance for partner integrations and platform enhancements, evaluates technical trade-offs, and supports mapping, transformation, and canonical data model decisions. The engineer is also the technical escalation point for complex production issues and root cause analysis. The role reviews designs, code, and mappings from offshore developers; leads design and code reviews; mentors developers; and drives corrective actions and standards updates. It partners with B2B specialists, product owners, and QA, collaborates with India and onshore teams across time zones, contributes to CI/CD, automated testing, and documentation, and communicates risks, dependencies, and progress to stakeholders.
