The Opportunity

We are looking for a talented, full stack Senior Software Engineer to drive technical execution and tackle complex challenges in our Insurance domain. This role requires a deep understanding of building scalable, modern applications while navigating the complexities of an industry with strict regulations, high data integrity requirements, and intricate workflows.

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.

Success in this role is measured by your ability to evolve our core systems with a relentless focus on Business ROI and long-term technical health. Beyond writing exceptional code, you will champion the integration and adoption of AI tools, agentic workflows, and other efficiency drivers to fundamentally reshape how we develop software.

What You Will Do

As a Senior Software Engineer your core responsibilities include:

  • Design & System Evolution: Decompose complex business scenarios into clean, service-based architectures and distributed systems. Modernize legacy platforms with a focus on simplicity, maintainability, and long-term ROI.
  • Domain Alignment: Translate complex insurance rules (claims, eligibility, remittance) into clean, high-performing technical solutions.
  • Epic Ownership: Own the delivery of Epics end-to-end, actively managing risks, dependencies, and team-level DORA KPIs while ensuring system performance and delivery reliability.
  • Full-Stack Development: Write clean, robust, and maintainable code across the stack, leveraging modern JavaScript frameworks (React) on the frontend and .NET Core/.NET Framework on the backend.
  • AI-Assisted Engineering: Champion responsible, AI-assisted development. Actively integrate AI tools (e.g., Claude, GitHub Copilot) to automate design, test generation, and code reviews, and build agentic workflows to drive team efficiency.
  • 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").

Education & Core Experience

  • Professional Experience: 10+ years of professional software development experience, with a minimum of 4+ years in a Senior Software Engineer role (or equivalent).
  • Education: 4-year Bachelor's degree in a STEM (Science, Technology, Engineering, Mathematics) major or a Master's degree in Technology or Computer Science or related field.

Core Technical Expertise

  • Backend Ecosystem: Strong, hands-on experience with the .NET Ecosystem (.NET Core / .NET Framework) and robust relational database design using SQL Server (including query optimization).
  • Frontend Ecosystem: Extensive experience building highly responsive, scalable user interfaces using modern JavaScript frameworks-specifically React and/or Angular (Required).
  • All qualified applicants will receive consideration for employment without regard to race, color, national origin, age, ancestry, religion, sex, sexual orientation, gender identity, gender expression, marital status, disability, medical condition, genetic information, pregnancy, or military or veteran status. We consider all qualified applicants, including those with criminal histories, in a manner consistent with state and local laws, including the California Fair Chance Act, City of Los Angeles' Fair Chance Initiative for Hiring Ordinance, Los Angeles County Fair Chance Ordinance, and San Francisco Fair Chance Ordinance.
