• Proven ability to work with legacy codebases, including refactoring, debugging, and performance optimization.

• 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.
