About The Position

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.
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.
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.

Requirements

• 4+ years of experience in back-end development using Python and FastAPI.
• 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.

Nice To Haves

• 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.

Responsibilities

• 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.

Benefits

• Cutting-edge technology: Work directly with the latest advancements in generative AI and automation, tackling challenging problems that meaningfully impact healthcare.
• Ownership & growth: You’ll join Ascertain at a pivotal early stage, shaping our products, technical direction, and culture, with significant opportunities for career advancement.
• Collaborative team: Join a talented, passionate, and supportive team with backgrounds from top tech companies and clinical institutions.
• Flexible hybrid work: We support a flexible hybrid working model from our NYC office, trusting you to manage your own schedule.
• Competitive compensation: We offer competitive salary, meaningful equity, comprehensive health insurance, and more.
