At nFerence Labs, the "Google of Biomedicine", we are building the world's first massive-scale platform for pharmaco-biomedical computing. Our platform is premised on using AI/Deep Learning (on clinical text, medical images, and other signals) and massive high-performance computing to help pharma companies perform faster and more efficient drug discovery, and also help early diagnosis of several key diseases.

We collaborate heavily with premier medical institutions such as the Mayo Clinic and build systems to get deep medical insights from patient information including patient notes and lab information, medical images, ECGs, etc. We are a well-funded company and are looking to grow on all fronts.

We are hiring an experienced backend staff engineer for our Pramana team. Our Digital Pathology-as-a-service venture, Pramana is an in-line quality assurance software suite which for the first time in the industry, provides confidence to the labs for the accuracy and applicability of their digital assets while supporting industry-standard image formats.

Pramana’s whole slide imaging system is built upon the strong hardware expertise of former Spectral Insights (that nference acquired in 2020) and the strong software expertise of nference. Modular systems with Robotic automation have allowed Pramana to reduce the reliance on several technical staff. This will significantly reduce the total costs of ownership and is a more transparent model for Pramana’s clients.
