Backend Software Engineer

As a Backend Software Engineer at Ascertain, you will build scalable, robust infrastructure and backend services that power Ascertain’s healthcare AI platform. You’ll take the lead in defining best practices around our infrastructure, security, CI/CD pipelines, and cloud hosting strategy. As one of our earliest engineering hires, you’ll have significant ownership in shaping both technical architecture and our engineering culture.

You’ll work closely with product and engineering teams to ensure our platform remains secure, performant, reliable, and scalable. While your primary focus is backend and infrastructure, our team is small—engineers are empowered to work across the stack when needed to fully own a feature.

You will design and develop scalable back-end services using Python and FastAPI. Support infrastructure management using Kubernetes, Docker, and Terraform. Work closely with product managers, designers, and other engineers to define technical requirements and translate them into robust software solutions. Participate in code reviews, providing constructive feedback and ensuring high-quality code standards. Contribute to improving software development processes and best practices.
