How to Apply for Senior Scientist/Scientist - Immunology - Viral Vaccines

at PopVax

🏢 About PopVax

PopVax is a unique full-stack biotech company that integrates machine learning-driven design with end-to-end RNA medicine development and manufacturing. 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 global health challenges with cutting-edge technology.

About This Role

This Senior Scientist/Scientist role focuses on immunology for viral vaccines, specifically contributing to PopVax's pipeline including Hepatitis C, COVID-19, influenza, and HPV vaccines. You'll be working at their RNA Foundry in Hyderabad, applying immunological expertise to vaccine design and development in a fast-paced, iterative environment that values tight feedback loops between research and manufacturing.

💡 A Day in the Life

A typical day might involve designing and executing immunological experiments to evaluate RNA vaccine candidates, analyzing data from animal studies, collaborating with computational teams on ML-driven design iterations, and contributing to documentation for regulatory requirements. You'd be working in their RNA Foundry facility, balancing bench work with cross-functional meetings to advance vaccine programs toward clinical development.

Practice questions for this role

🎯 Who PopVax Is Looking For

  • PhD in Immunology, Virology, or related field with 3+ years of post-doctoral or industry experience in vaccine immunology, particularly with RNA-based platforms
  • Hands-on expertise in immunological assays for vaccine evaluation (neutralization assays, ELISpot, flow cytometry, cytokine profiling) and experience with viral challenge models
  • Proven ability to work in interdisciplinary teams combining computational design (machine learning) with empirical validation in vaccine development
  • Experience with GLP/GMP environments and understanding of regulatory requirements for vaccine development, given PopVax's integrated R&D and clinical dose production facility

📝 Tips for Applying to PopVax

1

Highlight specific experience with RNA vaccine platforms and how you've contributed to vaccine programs from design through preclinical development

2

Demonstrate understanding of PopVax's 'tight feedback loops' philosophy by describing projects where you rapidly iterated between design, testing, and optimization

3

Connect your past work to their specific vaccine targets (Hepatitis C, COVID-19, influenza, HPV) even if indirectly - show you understand the immunological challenges of these viruses

4

Mention any experience with machine learning or computational tools in immunology research, as this aligns with their ML-driven design approach

5

Reference their 'Million Lives Mission' and explain how your work could contribute to this specific goal, showing you've deeply engaged with their mission

✉️ What to Emphasize in Your Cover Letter

['Your experience with RNA vaccine immunology and how it applies to their specific viral targets', 'Examples of working in integrated R&D environments with rapid iteration between design and testing', "How your background aligns with their funding partners' priorities (Gates Foundation, BARDA focus areas)", 'Specific contributions you could make to their 2026 Phase I clinical trial timeline for their first vaccine program']
