Staff Engineer (Enterprise Systems)

About Fullscript We’re an industry-leading health technology company on a mission to help people get better. We started in 2011 with one simple idea. Make it easier for practitioners to access the products they trust so they can deliver better care. That simple idea grew into a platform that powers every part of care. Today, more than 125,000 practitioners use Fullscript for clinical insights, lab interpretations, patient analytics, education, and access to high-quality supplements. Over 10 million patients rely on Fullscript to stay connected to their care plans and follow through on treatment. We build tools that make care smarter and more human. Tools that save time, simplify decisions, and help practitioners stay closely connected to the people they care for. When everything they need is in one place, they can focus on what matters most: helping people get better. This is your invitation. Bring your ideas, your grit, and your care for people. Join us and shape the future of care.

The Role

We are seeking a Staff Engineer to set the technical direction for Enterprise Systems, the critical technology layer connecting our e-commerce platform with our ERP, finance, demand planning, and warehouse management systems. Every order, shipment, and dollar of revenue flows through this domain.

As a Staff Engineer, you will combine deep, hands-on engineering expertise with systems-level thinking and organization-wide influence. You will lead complex, cross-functional initiatives, guide architectural decisions, and ensure the domain remains reliable, scalable, and secure for the long term, all while actively designing, building, and shipping software.

You will collaborate closely with fellow Staff Engineers, Tech Leads, Engineering Managers, business stakeholders, Security, and other cross-functional partners to solve complex problems in a rapidly evolving domain that is essential to Fullscript’s operations.

This is how we like building software 👉🏼 Fullscript Developer Handbook.

If you share our values, we’d be excited to talk with you!
