The urgency of our mission is not just about startup timelines; our clients depend on us to enhance financial resilience and operational clarity in a challenging environment.

Role Overview
As a Senior Backend Software Engineer at Ascertain, you will be instrumental in architecting and developing scalable backend services that underpin our healthcare AI platform. You will take charge of establishing best practices related to our infrastructure, security protocols, CI/CD pipelines, and cloud hosting strategies. As one of the first engineering hires, your contributions will be pivotal in shaping both our technical framework and engineering culture.
Working closely with product managers, designers, and fellow engineers, you will ensure our platform is secure, reliable, and performs optimally. Although your primary focus will be on backend development, our small team encourages engineers to engage across the technology stack to take full ownership of features.
With our headquarters in New York City, we also have a global engineering team that supports fully remote work, fostering a culture characterized by autonomy, shared responsibility, and profound respect for our users.
