This is an early, hands-on role on a team that is still taking shape, so the people we hire now will help set how we build. As a Senior Software Engineer, you will design, build, and support production microservices and integrations on our cloud-native platform, which is primarily C#/.NET on Azure today, with room for other languages and cloud platforms where they are the right fit. You will work closely with the Technical Lead, operations stakeholders, and a distributed team of internal and outsourced developers, and you will own your work from requirements through release and production support. We develop with AI-assisted tools every day, primarily Claude Code. We are looking for engineers who use these tools to move faster while staying fully accountable for correctness, security, and maintainability. What You'll Own Build & Integrate * Design, build, and maintain backend microservices and APIs, primarily in C# and ASP.NET Core * Build integrations with payer APIs and portals, clearinghouses, eligibility services, and internal platforms such as Salesforce * Design relational data models and write well-tuned SQL for high-volume operational workflows * Turn ambiguous business workflows into clear technical designs, and push back when a requirement doesn't make sense * Use AI-assisted development tools to accelerate implementation, testing, and refactoring, while reviewing every change for correctness and fit Quality & Reliability * Participate in code reviews, giving and receiving direct feedback across internal and outsourced developers * Support releases, rollbacks, and post-release validation in live environments * Improve logging, monitoring, observability, and documentation so the next person can understand and support what you built * Investigate and resolve production issues, using logs and monitoring to find root causes rather than symptoms Team & Delivery * Work closely with the Technical Lead on design decisions, estimates, and priorities * Collaborate with operations, product, QA, and business stakeholders to understand how the work is actually done * Mentor and support other developers as the team grows * Surface blockers and risks early, and communicate clearly about tradeoffs
