Full Stack AI Engineer

About Proscia

Pathology is at the center of medicine and is undergoing a profound transformation as the final frontier of digitization in healthcare. We started Proscia to accelerate pathology’s transition from microscope to images, and to use that AI to change the way we think about cancer. We can’t change medicine alone. That’s why we’re looking for curious thinkers. Big dreamers. Developers, evangelists, pathologists, and scientists. Exceptional talent to help us use the great power of AI for good and advance humankind.

At Proscia, we push the limits of medicine and technology, solving problems the world has never solved before. We build software used by thousands of scientists and pathologists who work on the front lines of fighting big enemies, like cancer, for patients around the globe. To accelerate our vision, Proscia has raised over $100M in capital from world-class healthcare and technology investors.

• Build scalable, cloud-based solutions using AWS, Docker, and Kubernetes.
• Design, test, and maintain safe, validated, and compliant AI solutions for regulated environments.
• Deliver high-quality, production-ready features at startup speed, embodying our “Challenge the Status Quo” value.
• Contribute to the evolution of the AI codebase, architecture, and technical standards.
• Support cross-functional teams by documenting and communicating designs, pipelines, and evaluation results to ensure reproducibility and transparency.
• Embrace AI as a default tool in problem-solving and development workflows, staying current with emerging frameworks.
