Frontier AI labs and pharma use them to answer one question: can an agent handle the messy, multi-layer reasoning that real biological work demands? Every benchmark is grounded in real experimental and clinical work, including designing experiments, interpreting data, reading clinical endpoints, and advancing compounds. Each is built by scientists who've done that work themselves. We're roughly 95 people in San Francisco, backed by Lux Capital, Coatue, Fifty Years, Haystack, Jeff Dean, Alec Nielsen, and George Church. We're seeking a Member of Technical Staff for Proteomics to lead our Proteomics benchmark and define how the field measures AI in this domain. ### About the Role You will design our technical approach to teaching agents how to understand and handle complex proteomic data, mapping out end-to-end data analysis workflows and working from instrument outputs to real scientific decisions. You will lead a team of software engineers and biologists building datasets to teach these agents to reason better across: Raw data QC, chromatography and instrument performance assessment Bottom-up proteomics: DDA and DIA acquisition, database search and spectral library workflows (e.g. DIA-NN, Spectronaut, MaxQuant, FragPipe) PTM analysis, including phospho and other enrichment workflows Untargeted and targeted metabolomics: feature detection, alignment, MS2 annotation and identification confidence levels (e.g. XCMS, MZmine, MS-DIAL) Lipidomics: class-level and species-level identification, nomenclature, and isomer ambiguity (e.g. LipidSearch, LipidXplorer) Normalization, batch correction, missing-value handling, and differential analysis across all three modalities Multi-omic integration and clinical or translational interpretation of MS data ### Requirements 5+ years hands-on experience generating and analyzing proteomics data (eg. LC/MS) Demonstrated experience with at least one of metabolomics or lipidomics, ideally from a core facility, platform company, or pharma biomarker group Prior contribution to a novel proteomics method, tool, or published pipeline Proficiency in coding and agents ### Culture @ Latch How we work. Genuinely flexible schedules— we only ask that you are extra communicative when you're coming in later than usual. We care most about hard work and output. We're respectfully opinionated, it will always be us against problems, never each other. We optimize for each other's time and bring solutions, not just problems. Office & Perks. Waterfront office near Oracle Park, 2x free daily meals, unlimited snacks, company outings most months, and team offsites. Plus a vibrant Latch community: cycling, soccer, figure skating, boxing, run clubs, reading clubs, martial arts, music, game nights. ### Compensation & Logistics Full-time, in-person Unlimited PTO (truly) Work Visa sponsorship Flexible Spending Account 401 contribution (no match) Profit Share + Ambitious Equity Team-wide science reading groups 100% covered Health, dental, vision Relocation Assistance (if applicable) Lunch and dinner provided every workday Waterfront office in China Basin, San Francisco Company-sponsored professional development Flexible working hours, so long as you maintain an onsite presence Best office dog: Nix ### Interview Process Intro Screen (30m): Recruitment Team Intro Technical Screen (30m): Member of Technical Staff/CTO Deeper Technical Screen (1hr): Member of Technical Staff/CTO Onsite Work Trial: 2-3 days (we will take care of all accommodations) Decision: 1-3 days after your interview --- Data: alder (https://alderhq.app).
