Company Summary

Apriori Bio is an early-stage biotechnology company with an ambitious and exciting mission: to lay the foundation for Global Pathogen Shield™ protective interventions that that can neutralize a wide range of the most dangerous and rapidly evolving infectious pathogen threats. The company is developing a revolutionary approach to this challenge, based on a powerful combination of deep experimental and computational approaches, and actively recruiting a team of top-tier scientists to build what it believes will be a first-in-category R&D platform with truly global impact.

Apriori Bio is a product of Flagship Pioneering’s venture creation engine, which has also given rise to companies such as Moderna Therapeutics (NASDAQ: MRNA), Rubius Therapeutics (NASDAQ: RUBY), and Editas Medicines (NASDAQ: EDIT). Since Flagship’s founding in 2000, the firm has originated and fostered the development of more than 100 scientific ventures, resulting in over $34 billion in aggregate value, 500+ issued patents, and more than 50 clinical trials for novel therapeutic agents.

 Position Summary:

We are seeking an entrepreneurial, strategic, driven, and visionary scientific expert in viral and/or molecular biology to join Apriori Bio as our Head of Discovery Platform. In this role, you will serve as a critical part of Apriori's R&D Leadership Team, establishing Apriori as the global leader in designing variant-proof vaccines and antibodies. You will lead the platform team towards fulfilling the broadest vision for Apriori, continuously developing and expanding the platform through state-of-the-art scientific innovation, strategic decision-making, and operational excellence. You will work in close collaboration with other Apriori leaders, including the Head of Translational Immunology and Head of Computational Sciences, to build a new type of company, successfully combining deep scientific excellence – including high-throughput biology interrogation – with modern computational technologies to enable the systematic design of life-changing medicines. Along with the broader leadership team, you will also partner with key colleagues in the articulation and execution of the company’s scientific, technological and commercial strategies. 

This is a critically important role for Apriori Bio that will include building out the Discovery Platform team. The candidate will be responsible for the design, construction, optimization and scaling of a suite of molecular tools and innovative high-throughput assays through which Apriori will evaluate the properties and behavior of viral variant proteins and antibodies. (S)he will have a track record of success in inventing and deploying sophisticated new tools for high-volume, high-speed discovery, and deriving unique insights from biological data – particularly as regards protein-protein interactions, protein structure, viral protein function, viral escape and human immune system biology. Experience with the design of interventions such as vaccines or antibody therapeutics is a strong plus. An essential element of the role will be the ability to collaborate closely with other R&D scientists while adapting to and interpreting new experimental findings and providing experimental guidance in keeping with the company’s objectives.

Key Responsibilities:

  • Formulate, articulate and implement strategies to drive the generation of new insights and ensure that these are reflected in the company’s broader scientific vision and value proposition
  • Build insights and perspectives to help inform Apriori’s scientific, technological and commercial strategies, including by partnering closely with colleagues across other company functions

  • Working closely with molecular biologists, molecular virologists, computational scientists and others within and beyond Apriori Bio, to lead and build a team focused on the design and deployment of innovative, proprietary tools and assays
  • Coordinate and oversee critical data-generating experiments
  • Build an infrastructure of laboratory protocols, tools and systems to enable focused and rapid discovery and early pipeline development; lead efforts to optimize and scale so as to maximize the productivity and value of the company’s technologies
  • Establish and oversee external projects and scientific collaborators and contract research organizations
  • Spearhead scientific and technical expertise through fluency in relevant scientific literature, attending conferences, and developing relationships with thought leaders, and building on these as necessary to support company objectives
  • Develop relationships with Flagship Pioneering’s broader science community and manage external consultants as needed
  • Communicate insights and conclusions to the scientific team and executive management


  • PhD or equivalent in molecular biology, cell biology, biochemistry, or a related field
  • 12+ years of postdoctoral experience developing tools, assays and high-throughput discovery platforms – including in an industry setting
  • Track record of leadership in developing strategic timelines and successfully delivering against company goals
  • Strong expertise in molecular biology
  • Good understanding of evolutionary and/or viral biology at the level of molecular systems
  • Extensive experience of high-throughput assay development and/or robotic systems
  • Experience in immunology, virology and/or vaccine design
  • Previous work with biological sequence or protein structure datasets
  • Demonstrated ability in working with highly skilled teams in a fast-paced, entrepreneurial and technical environment
  • Track record of success in developing and growing scientific teams
