Full Stack Developer - Dotnet

Responsibilities:

• You'll use AI agents (Cursor, Claude Code, Codex) to blow through framework upgrades, refactors, API extraction, test scaffolding, and documentation - while catching hallucinations and preventing regressions before they hit a PR. Build reusable playbooks the team can actually follow: prompt templates, repo-level agent instructions, migration checklists, review heuristics, and clear "definition of done" standards for AI-assisted changes.
• You'll upgrade legacy services to current ones. NET (LTS where it makes sense), untangling architecture boundaries and fixing the performance issues that have been "known" for years. Push toward a proper API-layer architecture - RESTful, versioned - built for correctness and maintainability, not just "it works. " Get your hands dirty with SQL Server: query performance, indexing, transactional correctness. If there are data pipeline needs (Kafka, etc. ), you'll help build those too.
• You'll build with security and privacy as defaults, not afterthoughts. Least privilege, safe data handling, the works. This is healthcare - getting it wrong isn't an option. Put real quality guardrails in place: automated tests that actually catch things, CI that blocks bad changes, structured logging, and observability that tells you what's happening before users do. Review code thoughtfully, have honest architectural conversations, and raise the bar without being a jerk about it.
• You'll partner with analysts, stakeholders, and other engineers to turn business problems into working software - not just technically correct software, but software that actually solves the problem. Help build delivery plans that are honest about trade-offs. "Right" vs. "right now" is a real tension - you'll help the team navigate it with pragmatic milestones.

Requirements:

• 5+ years building and shipping production systems. Not side projects - real software with real users, solving skills; able to work independently and collaboratively in fast-moving teams.
• Some C# and modern. NET experience (Core and beyond).
• Especially in large codebases, and you've done meaningful refactoring and migration work, not just greenfield.
• Front-end experience with Angular and/or React/Next.js .
• Strong SQL Server chops - schema design, query tuning, performance troubleshooting.
• You've worked on data-heavy applications where the database wasn't an afterthought.
• Cloud experience with Azure and/or AWS.
• Azure is particularly relevant here.
• API design experience - you've built and maintained service-oriented architectures with real versioning, auth, reliability, and testing practices.
• You actually use AI coding tools as a daily driver. Cursor, Claude Code, Codex, or similar - and not just for autocomplete.
• You've used agents for multi-file refactors, migrations, test generation, and review workflows.
• You have opinions about what works and what doesn't.
• You communicate clearly.
• Good PR descriptions, straightforward design docs, pragmatic collaboration, and low ego. We don't need a rockstar - we need someone the team trusts.
