Position: Full Stack Engineer (.NET)

We are seeking a mid-level Full Stack Engineer with strong .NET backend expertise and solid front‑end experience to support the modernization of a large-scale insurance platform. This role is focused on migrating and transforming a legacy monolithic application into a modern, microservices‑based architecture.

You will play a key role in accelerating the migration of approximately 190 insurance claim configurations into a new system, working hands‑on in both legacy and modern codebases.

Key Responsibilities
  • Support the migration of a legacy .NET/C# monolithic application to a modern architecture.
  • Analyze existing configurations and logic, and replicate/migrate them into a new platform.
  • Work heavily in .NET (backend) to understand and translate legacy business rules.
  • Contribute to the modern application built with Vue.js and .NET Core microservices.
  • Integrate and support real‑time API calls across policy and claims systems.
  • Handle client‑specific configurations, including custom rules and data inputs.
  • Leverage AI tools (e.g., Cursor) to navigate and analyze multiple repositories.
  • Contribute to improving developer workflows, including AI‑assisted processes.
  • Collaborate within an Agile/Scrum team (execution‑focused role).
Skills and Requirements
  • 5+ years of experience in full stack development (mid‑level preferred) – 60% back end, 40% front end.
  • Strong experience with .NET / C# – backend development focus.
  • HTML/CSS knowledge.
  • Experience working with or migrating legacy systems.
  • Solid understanding of API development and integration.
  • Working knowledge of modern JavaScript frameworks (Vue.js preferred).
  • Experience using Git and working across multiple repositories.
  • Experience with microservices architectures.
  • Familiarity with AI‑assisted development tools (e.g., Cursor or similar).
  • Exposure to insurance, claims, or policy systems.
  • Experience with cloud platforms (Azure and/or AWS).

We are a company committed to creating diverse and inclusive environments where people can bring their full, authentic selves to work every day. We are an equal opportunity/affirmative action employer that believes everyone matters.
