Lead, Regulatory Affairs CMC - Cell Therapy & Novel Therapeutics

Retro develops therapies for diseases driven by the biology of aging. We focus on cellular reprogramming and autophagy to rejuvenate cell and tissue function with the ultimate aim of adding 10 years to healthy human lifespan.

We’re hiring an experienced new member of our Regulatory team who will own the strategy and operations for our Chemistry, Manufacturing, and Controls (CMC) regulatory work. As one of the earliest members of the Regulatory Affairs team, you will work across Retro’s programs and play a leading role in building out the regulatory CMC capabilities and strategies to achieve our ambitious mission and tackle aging. You will report directly to the Head of Regulatory Affairs.

This position is an onsite role based in Redwood City.

About you:

You are a builder and doer who can set clear, global CMC regulatory strategies and roll up your sleeves to execute them at speed. You are energized by complex CMC challenges, especially in cell therapy, and you anticipate questions before they become risks. You translate technical details into clear regulatory narratives that resonate with health authorities, and you are comfortable serving as the CMC regulatory point person in high-stakes health-authority interactions.

You have high-collaboration and low-ego tendencies, with the ability to align cross-functional technical teams and external partners around a shared regulatory CMC plan and clear deliverables. You bring strong operational discipline, enjoy creating structure when needed, and are mission-driven with genuine motivation to advance longevity and aging biology for the benefit of humanity.
