Senior Software Engineer – IRIS Platform & Claims Systems

About the role

This role is part of a dedicated team supporting a mission critical healthcare claims platform, built on InterSystems IRIS / Caché, MUMPS, ObjectScript, and proprietary development tooling. This engineer serves as a technical anchor for the platform — ensuring stability, correctness, and long-term sustainability while the platform continues to evolve. This senior role combines hands‑on software engineering with leadership in integrating AI-assisted tools into enterprise development workflows.

Responsibilities

• Design, build, test, and deploy enhancements to the IRIS based Claims platform.
• Serve as a technical steward for core system patterns, data models, and platform conventions.
• Diagnose complex system issues and recommend preventative improvements.
• Review and validate changes to ensure correctness, performance, and maintainability.
• Partner with business and technical stakeholders to translate requirements into robust solutions.
• Provide mentoring and guidance to other developers.
• Support audits, documentation requests, and vendor interactions as needed.

Requirements

• Bachelor’s degree in Computer Science, MIS, Business Administration, or equivalent experience.
• Six (6) years of experience designing and developing enterprise software in a collaborative environment.
• Strong background in backend systems and data intensive applications.
• Experience working across multiple languages and platforms (e.g., IRIS/MUMPS/Caché, ObjectScript, Java, C/C++, C#, .NET, or similar).
• Strong experience developing, maintaining, and supporting MUMPS/InterSystems IRIS or Caché–based systems in an enterprise environment.
• Proven ability to work with legacy codebases, including refactoring, debugging, and performance optimization.
• Experience using AI-assisted development tools (e.g., Claude Code, GitHub Copilot, or similar) to improve developer productivity, code quality, or documentation.
• Experience with relational and/or nonrelational database technologies.
• Demonstrated desire and ability to grow into an application owner and subject matter expert.
• Willingness and curiosity to learn proprietary tools and platforms.
• Ability to support production systems, including participation in an on-call rotation.

Qualifications

• Eight plus (8+) years of experience designing and developing enterprise software in a collaborative environment is strongly preferred.
• Experience designing or using agentic AI workflows (e.g., AI agents for code generation, refactoring assistance, test creation, or knowledge extraction from legacy systems).
• Familiarity with integrating AI tools into enterprise development workflows, including prompt engineering, guardrails, and human‑in‑the‑loop validation.
• Exposure to modernization efforts, such as supporting API enablement, service decomposition, or migration from legacy MUMPS environments to hybrid or modern architectures.
• Understanding of healthcare or claims processing systems and regulated data environments.
• Experience with high volume, mission critical transactional platforms.
• Strong data modeling and system design skills.
• Experience mentoring developers and establishing development patterns and best practices.

Skills

• Curiosity and methodical approach to problem-solving.
• Comfortable working in complex, high volume transactional systems.
• Willingness to grow into a technical leadership and ownership role for major areas of the platform.
