Senior Software Engineer- C#/React

Senior Software Engineer- Marketplace Engineering

RevSpring is building a new greenfield product in the healthcare access space. This is a ground-up build: you will own architectural decisions, establish development patterns, and work directly with product leadership from day one. The team is intentionally small, which means high ownership and direct impact. This product is consumer-facing and transaction-oriented. Candidates with backgrounds in e-commerce, retail technology, or consumer SaaS will find the problem space familiar. Prior healthcare IT experience preferred but not required. RevSpring develops software using an AI-augmented engineering model. Claude Code is a required tool on this team. Candidates are expected to demonstrate working fluency with Claude Code as part of the interview process.

• Develop full-stack features across a.NET backend and React frontend
• Establish development standards, code review practices, and architectural patterns for a new engineering team
