latchbio - AI Biologist - Biologics Development

• PhD in protein engineering, biochemistry, analytical chemistry, pharmacology, or a related field • Hands-on analysis of antibody development data. You’ve done the analysis yourself, not just supervised it • Deep expertise in at least one area (analytical/CMC characterization, large-molecule DMPK, protein engineering and developability, or non-clinical safety) and working fluency across the others • Command of how readouts map to critical quality attributes, PK and effector properties, and release or comparability decisions • Python or R for data analysis, including parsing chromatograms and electropherograms, kinetic fitting, or PK modeling • AI-ready from day one: daily use of Claude, Cursor, or similar agents, with the judgment to spot where model reasoning is technically correct but scientifically unsound • Confidence to overrule an AI agent when the evidence demands it, and the openness to update when shown wrong • Ability to calibrate confidence and communicate uncertainty rather than defaulting to binary calls • Bonus: antibody format and Fc engineering experience (IgG subclasses, YTE/LS, effector-silencing, bispecific architectures) • Bonus: familiarity with MAM, ICH Q6B/Q5E, FDA immunogenicity guidance, IMGT, SAbDab, and IEDB • Culture. We practice radical transparency: you’ll know how the company is doing, what’s working, and what isn’t. It’ll always be us against the problem, never each other. We’re opinionated but respectful, and we bring solutions with our problems. You decide how you work; we judge the output. We use AI constantly, so what we reward is original expert judgment, not AI output passed off as your own. You’ll start on the bench that fits your expertise and can move across teams as you build a track record. People who do well here and bring leadership experience can move quickly into senior roles. Outside of work, we have company outings most months, team off-sites, a Latch run club, cycling, boxing, ice skating, and soccer. Feel free to add to the list.
