As a Senior Engineer, you will serve as a critical technical problem-solver--- who takes extreme ownership of building scalable, highly reliable software systems in an agile environment. In this role, you will navigate the technical and regulatory complexities of insurance eligibility, claims processing, and remittance workflows. You will work closely with domain experts, product managers, and engineering peers to modernize legacy systems, design service-based architectures, and deliver high-impact software.

• Software Design & Quality: Set rigorous standards for code quality through constructive code reviews, comprehensive automated testing (including AI-driven test suites), and continuous integration/delivery (CI/CD).
• Technical Leadership & Mentorship: Guide junior and mid-level engineers on software design patterns, debug cross-module issues, and act as a professional stakeholder manager who can navigate technical disagreements constructively ("disagree and commit").

Requirements

• 10+ years of professional software development experience in .NetCore
