About the job

Requirements
  • Ph.D. or equivalent research experience in computational chemistry, chemoinformatics, physical chemistry, medicinal chemistry, chemical engineering, or a related field.
  • Experience with molecular descriptors, similarity methods, quantitative structure–activity relationship (QSAR), molecular machine learning, or graph-based models.
  • Strong Python skills and experience with RDKit or equivalent chemical-computing libraries.
  • Ability to design leakage-resistant evaluations and interpret model performance in chemical rather than purely statistical terms.
  • Clear scientific writing and close collaboration with experimental teams.
Responsibilities
  • Develop molecular representations and predictive models for compound effects on mosquito landing and related behavioral endpoints.
  • Combine chemical structures and descriptors with formulation, dose, assay, environmental, and behavioral data.
  • Design prospective evaluations that measure whether model-ranked compounds outperform conventional selection approaches.
  • Quantify uncertainty, identify out-of-domain predictions, and propose experiments that distinguish competing chemical hypotheses.
  • Partner with formulation chemists and machine-learning researchers to recommend the next compound, dose, formulation, or controlled variant to test.
  • Build reproducible computational workflows with traceable structures, descriptors, model versions, and experimental outcomes.
  • Develop molecular representations and predictive models for compound effects on insect landing on crops and related behavioral endpoints.
  • Combine chemical structures and descriptors with formulation, dose, assay, environmental, and behavioral data.
  • Design prospective evaluations that measure whether model-ranked compounds outperform conventional selection approaches.
  • Quantify uncertainty, identify out-of-domain predictions, and propose experiments that distinguish competing chemical hypotheses.
  • Partner with formulation chemists and machine-learning researchers to recommend the next compound, dose, formulation, or controlled variant to test.
  • Build reproducible computational workflows with traceable structures, descriptors, model versions, and experimental outcomes.
Desired Qualifications
  • Experience with active learning, Bayesian optimization, uncertainty calibration, or prospective molecular discovery.
  • Knowledge of volatility, solubility, controlled release, odorants, or insect-active small molecules.
  • Experience connecting computation to iterative wet-lab experiments.
  • Interest in building open, reusable scientific methods rather than a one-time screening model.

About the company

Monarch Crops develops non-toxic spatial repellents to protect crops from insect damage. The product works by emitting signals that cause insects to avoid landing on treated crops, leveraging natural olfactory cues rather than killing insects. Monarch combines a comprehensive dataset that includes genomic, molecular, and behavioral information with computational chemistry and machine learning to identify natural compounds that trigger an avoidance response in insects. This data-driven discovery aims to formulate repellent products that safeguard crops while keeping humans and the environment safe. Unlike traditional insecticides, Monarch focuses on prevention through odor-based avoidance and seeks sustainable pest management solutions to reduce crop losses and health risks associated with toxic chemicals. The company’s goal is to enable crop protection that is effective, environmentally friendly, and economically viable for farmers.

Simplify's Take

What believers are saying

  • Monarch's August 2026 website says it is developing a product that works.
  • Four open R&D roles in February 2026 show active experimentation and team building.
  • Lead Entomologist hiring cited machine-learning-predicted compounds, validating the core discovery approach.

What critics are saying

  • No public field trials, customer contracts, or revenue prove the repellent works commercially.
  • Hiring remains research-heavy in Alameda and Oakland, signaling product risk and long development timelines.
  • If efficacy misses broad-spectrum insects, Monarch becomes another biotech platform with no defensible market.

What makes Monarch unique

  • Monarch builds a spatial repellent, not a conventional insecticide, targeting crop protection.
  • Its data engine combines genomics, behavioral assays, and computational chemistry for compound discovery.
  • Open roles in formulation chemistry and computational entomology show a deep wet-lab plus ML moat.
