Proscia is a leader in pathology AI software, backed by over $100 million in funding, revolutionizing digital pathology and medical imaging. The company empowers pathologists and scientists to transition from traditional microscope-based workflows to AI-driven approaches, unlocking new possibilities in precision medicine. As a Senior Software Engineer, you will help build and evolve the software platform powering the future of digital pathology. You'll work across the full application stack—from scalable backend services and APIs to modern web applications and cloud-native infrastructure—delivering enterprise-grade software used in real-world healthcare environments. Key responsibilities include designing, developing, testing, and deploying scalable services and applications; building and maintaining modern APIs, microservices, and web applications using TypeScript and Vue; collaborating within high-performing Agile/Scrum teams to define and deliver impactful features; and partnering with engineering teams across Proscia to ensure interoperability and platform consistency. You will contribute to frontend architecture and user experience improvements for complex, data-intensive applications, participate in architectural design discussions, and help drive best practices for scalability, observability, maintainability, and performance. The role emphasizes an AI-first mindset, with expectations to integrate modern intelligent tools into engineering workflows and demonstrate experience developing with large language models, agentic pipelines, or AI agents. You should be fluent in prompt engineering, tool-use patterns, and evaluation of AI systems. The ideal candidate has strong experience with TypeScript, Node.js/Deno, PostgreSQL, modern frontend development (Vue preferred), automated testing, and service-oriented architectures, along with a passion for building high-quality software and continuously improving engineering practices.
