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 handson software engineering with leadership in integrating AIassisted tools into enterprise development workflows. In addition to serving as a technical anchor, this position helps define and scale the use of AI across the development lifecycle, including prompt engineering, guardrails, and humanintheloop validation, to ensure responsible and effective adoption.

The ideal candidate is curious, methodical, and comfortable working in complex, high volume transactional systems, and will grow into a technical leadership and ownership role for major areas of the platform.

This is a newly created role reporting to the Director of Healthplan Administrative Systems. The position is part of a fifty-three-person department and will be one of fifteen direct reports, working alongside Developers, Engineers, Scrum Masters, and Managers.

• 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/Cache, ObjectScript, Java, C/C++, C#, .NET, or similar).
• Strong experience developing, maintaining, and supporting MUMPS/InterSystems IRIS or Cache-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.

Preferred 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 humanintheloop 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.

Hours/Location:

• M-F; core business hours
• This is a hybrid position with the flexibility to work primarily remotely, with occasional onsite presence required for meetings or workgroup sessions.
• The role participates in an on-call rotation shared across the team, averaging approximately 2-4 weeks per year.

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.
