Senior Full-Stack Developer

We're looking for developers who think like architects, not just coders. The ideal candidate will have opinions about our repository pattern, suggestions for improving our event-driven architecture, and questions about our workflow orchestration approach. Prioritize candidates who demonstrate critical thinking and strong communication skills over those who simply list our tech stack on their resume.
