I joined Icosavax to help demonstrate the impact a single lab bench can have on a startup’s R&D speed and efficiency. I stay to be a part of what we can accomplish with many more.

The Icosavax team is great at hiring talented people, and the team values different perspectives.

I love the mission of the company to create computational designed vaccines for infectious diseases. It is a bigger bonus to work with sharp, focused, FUN and diverse people pursuing a common goal.

Diversity & inclusion

We’re focused on DOING GOOD for the world, but also for the people helping us achieve our goals.

Our values underpin everything we do, including our approach to—and beliefs surrounding—diversity and inclusion:

We’re striving to become a progressively more diverse and inclusive organization.

We encourage self-expression of all kinds and know that we greatly benefit from our employees contributing their unique views. We’re nurturing a culture that welcomes a diversity of races, genders, ages, physical and mental abilities, identities, ethnicities, religions, and perspectives.

We want people to own who they are and proudly bring that to work. In addition, as a company, we’re taking ownership of developing best-in-industry policies and advancing a company philosophy that allows for authentic individuality.

Data Driven
We don’t just talk about diversity and inclusion, we’re actively measuring how we’re doing. We’re excited to continue to foster an ever-more inclusive and diverse company as we grow, and will continue to measure our progress towards that goal.
