Full Stack Engineer at Ascertain
Meet Ascertain
Ascertain is building AI agents to automate the administrative work that burdens care teams. We are in major health systems and large specialty groups, saving hundreds of staff hours every week.
Our backers include Northwell Health, New York’s largest health system, and Deerfield Management, a leading healthcare investment firm.
Together, we’re on a mission to restore time, trust, and focus to the people who keep healthcare running. Our work is urgent — not because of startup timelines, but because our customers rely on us to drive financial resilience and operational clarity in a system under strain.
About the Job
As a Full Stack Engineer at Ascertain, you will build the robust infrastructure, services, and applications that comprise 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. You'll own core areas of functionality and develop them end to end—shaping both technical architecture and our engineering culture.
Ascertain is headquartered in New York City, where part of our engineering team works in person. We also hire engineers across the U.S. for fully remote roles, and we operate with a culture of high autonomy, shared accountability, and deep respect for the people who use what we build.
What You'll Do:
Develop scalable back-end services using Python and FastAPI.
Build intuitive front-end applications using React and TypeScript.
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.
What You'll Need:
4+ years of experience in full stack development using Python, FastAPI, and TypeScript.
Experience with relational databases (PostgreSQL) and other stores (Redis) a plus.
Familiarity with containerization (e.g. Docker, Kubernetes) and CI/CD workflows.
Experience with infrastructure provisioning using Terraform and Docker.
What You'll Bring to the Table:
You have a security-minded approach to software design, with experience in regulated environments a plus.
Experience in ambiguous startup environments, proactively take ownership, and communicate clearly across teams.
Excitement (not just willingness!) to dive into new technologies, learn quickly, and step beyond your comfort zone in a rapidly evolving environment.
Benefits & Perks:
Cutting-edge technology: Work directly with the latest advancements in generative AI and automation, tackling challenging problems that meaningfully impact healthcare.
