How to Apply for Junior Scientist - Immunology - Vaccines

at PopVax

🏢 About PopVax

PopVax is a unique full-stack biotech company that integrates machine learning-driven design with empirical vaccine development, creating RNA medicines end-to-end at their Hyderabad RNA Foundry. Their ambitious 'Million Lives Mission' to save 1 million lives annually through novel vaccines and immunotherapies, backed by prestigious funders like the Gates Foundation and BARDA, makes this an opportunity to work on high-impact science with rapid iteration cycles.

About This Role

As a Junior Scientist in Immunology - Vaccines, you'll contribute to developing viral and bacterial vaccines using RNA technology, working within tight feedback loops between design and experimentation. This role directly supports PopVax's pipeline including Hepatitis C, Strep A, TB, COVID-19, influenza, and HPV vaccines, with the first program entering Phase I trials in 2026.

💡 A Day in the Life

A typical day involves designing and executing immunological experiments to evaluate RNA vaccine candidates, analyzing data to inform next design iterations, and collaborating with ML and manufacturing teams at the RNA Foundry. You'll work on specific disease targets like Hepatitis C or Strep A, with regular progress reviews to maintain rapid development cycles toward clinical trials.
