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

We’re building a mission-driven team of accomplished and kind individuals who embrace our startup culture of rapid iteration, transparency, and versatility.

We are seeking a new member of the Analytical Development team to drive hands-on, non-GMP analytical characterization studies for our iPSC-derived cell therapy products, including microglia and hematopoietic stem/progenitor cell programs. In this role, you will design and execute characterization studies for intermediates and drug product, with a focus on flow cytometry, functional assays, product-related impurities and variants, MoA-reflective biological activity, and IND-enabling product understanding. Your work will support QC method development, CQA definition, specification-setting, regulatory submissions, and long-term control strategy. You will report to the Head of Quality & Analytical and work closely with AD, QC, QA, and regulatory partners.

You are a rigorous, hands-on scientist who enjoys bringing structure and clarity to complex biological systems. You are energized by building something new, especially when the path is not fully defined and good scientific judgment matters. You take ownership of your work, think carefully about experimental design, and hold a high bar for data quality, documentation, and interpretation. You communicate clearly, ask good questions, and enjoy partnering across teams to turn complex data into shared understanding and practical decisions. You are adaptable, resourceful, motivated by impact more than rigid job boundaries, and excited to help build the analytical foundation that will move complex cell therapy products toward the clinic.

We take pride in cultivating an environment that fosters collaboration, open communication, and authenticity. We believe that great results are best delivered by a highly creative team working in concert. We are an equal opportunity employer; we do not discriminate based on race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status, or disability status. We are diverse in background and singular in mission.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
