The posting

Member of Technical Staff - Proteomics

Latch builds rigorous scientific benchmarks (benchmarks.bio http://benchmarks.bio) that measure how well AI agents perform real biology. 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

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
