Senior Integration Developer

Overview

Exostar enables trusted collaboration across the Aerospace & Defense (A&D) supply chain, supporting mission-critical Order-to-Cash (O2C) and Procure-to-Pay (P2P) processes across complex, multi-enterprise environments.

The Senior Integration Developer is a senior technical contributor within Professional Services, delivering complex enterprise integrations between Exostar’s SaaS platforms and customer ERP, procurement, and supply chain systems. This role requires specialized depth in integration architecture and development, and the ability to interpret customer business requirements to recommend scalable, high-performance solutions.

Operating with a high degree of independence, this individual will lead integration workstreams, mentor other developers, and ensure secure, scalable, and reliable implementations in enterprise customer environments.

Responsibilities

Your day if you join us:

• Lead the design and development of complex integrations between Exostar platforms and ERP systems (SAP, Oracle, Epicor, Infor).
• Interpret customer supply chain requirements and recommend scalable integration patterns aligned to O2C and P2P workflows.
• Own delivery of integration workstreams within enterprise implementations.
• Develop APIs, middleware configurations, event-driven integrations, and data transformation logic.
• Write, optimize, and troubleshoot advanced SQL queries and database logic.
• Apply object-oriented programming principles to develop maintainable, scalable integration components (Java, C#, PHP).
• Design and support multi-threaded, concurrent, and asynchronous processing solutions to handle high-volume transactions.
• Utilize GitLab and GitHub for source control, branching strategies, merge requests, and CI/CD workflows.
• Use Jira to track tasks, defects, and implementation progress within structured delivery engagements.
• Partner closely with QA Engineers to ensure robust testing strategies and release readiness.
• Mentor Integration Developers and serve as a senior technical resource for the team.
• Troubleshoot high-impact technical issues across development, test, and production environments.
• Leverage AI-assisted engineering tools (e.g., Claude Code, Opus) to enhance coding efficiency, documentation quality, and troubleshooting workflows.
• Contribute reusable assets and best practices to improve delivery consistency across Professional Services engagements.
