Senior AI Security Engineer II

About BlinkRx:

BlinkRx is rebuilding how Americans access life-changing medicines. Today, only one in five prescriptions for new branded therapies are ever filled. The problem isn't the medicine. It's insurance barriers, affordability challenges, fragmented pharmacy experiences, and inadequate support that keep patients from starting and staying on treatment. Our mission is to change that.

We built RxOS, the first AI-powered prescription operating system. RxOS connects the largest network of doctors, patients, pharmacies, payers, and pharmaceutical manufacturers, intelligently orchestrating every step to guarantee a seamless prescription journey for every script.

Our teams solve complex, high-stakes problems at the intersection of artificial intelligence, healthcare operations, logistics, payments, and regulation. The impact is transformative: BlinkRx more than doubles the rate at which patients take their medications and lowers their out-of-pocket expenses by hundreds of dollars every month.

BlinkRx created and leads a rapidly growing $80+ billion category, with exceptional momentum:

• Built for scale: Over the past decade, we have invested nearly $1 billion in building the technology and operational platform required to serve patients at scale.

• Proven growth and economics: We have grown 100% annually for the past five years, are profitable, and support more than 60 pharmaceutical brands.

• Trusted with category-defining programs: Our technology powers a leading pharmaceutical manufacturer’s direct-to-patient platform for its GLP-1 portfolio, providing the infrastructure to expand patient access as demand for these therapies grows.

We are a dynamic team of technologists and industry experts seeking to build a generational company that delivers a genuine step change in American health.
