About us:

Siftwell Analytics is a fast-growing company that combines healthcare operator expertise and artificial intelligence to equip community health plans with better insights to drive earlier and more precise health interventions for members. Siftwell was founded with a fundamental commitment to address the unique challenges faced by community health organizations, beginning with Medicaid, Marketplace, and Medicare plans, who are entrusted with the care of our most vulnerable and complex populations.

At Siftwell, we are committed to providing a mutually respectful work environment. We believe diversity and inclusion among our teammates are critical to our success. We seek to recruit, develop, and retain the most talented professionals from a diverse candidate pool, and we work to enable a culture in which all talented individuals can develop, have fun, and thrive.

About the role:

As a Principal Engineer (Full-Stack), you will design, build, and scale the technology that powers Siftwell’s platform, driving architecture, development, and delivery of high-impact, data-driven healthcare applications. Reporting to the Chief Technology Officer, you will balance strategic technical decisions with hands-on engineering, spending the majority of your time building, coding, and deploying alongside the team to ensure our products are reliable, scalable, and built for long-term success.

You will serve as Siftwell’s hands-on engineering lead, owning the full application stack and guiding all aspects of software design, build, and delivery. Partnering closely with Product, Data Science, and Customer Success, you’ll translate complex ideas into scalable, production-ready solutions. Your experience building full web applications end to end, from infrastructure to front end, will inform key architectural decisions and ensure Siftwell’s technology scales reliably as we grow.

As Siftwell builds an AI-enabled analytics platform, this role will apply modern development and automation tools to accelerate delivery and maintain quality, adopting technologies that improve speed, reliability, and cost efficiency within a regulated environment. You’ll thrive here if you enjoy solving complex problems, approach AI-assisted development with curiosity and pragmatism, and foster collaboration across disciplines while building systems in a fast-moving environment. As Siftwell continues to grow, this position will play a key part in shaping the foundation and practices of an expanding engineering team.

This position is remote within the United States and may require limited travel for team collaboration and planning sessions. The role operates on East Coast (U.S.) hours to ensure alignment with client and team schedules.
