Assist with periodic cycle counts and basic inventory cleanup.
Consistently follow chemical hygiene and safety procedures.

About the Company

onepot is building an automated small-molecule lab where robotics and software drive synthesis and analysis. This role is hands-on lab operations work that directly supports an automated workflow: accurate inputs, clean inventory, and reliable receiving are what keep the automation running.

About the Role

This part-time, on-site role in South San Francisco involves hands-on lab operations work that directly supports an automated workflow. Night shift availability is welcome.

Responsibilities

Compound handling & precision weighing (primary)

Accurately weigh solid compounds/reagents (mg to g scale) on analytical balances
Prepare labeled aliquots and staging sets that feed automated/robotic workflows
Maintain clean, contamination-aware weighing practices (gloves, anti-static control, clean tools)
Record weights, lot numbers, IDs, and operator/date in a traceable format

Stock solution preparation

Prepare stock solutions from SOPs (target molarity/concentration, dilution math, mixing)
Label and document concentrations, solvent, date, operator, and storage conditions
Flag solubility issues, discrepancies, or labeling/inventory mismatches

Receiving, staging & inventory (automation-ready)

Receive shipments, verify contents vs packing slips/POs, and triage issues (damage, missing items)
Log inventory and assign locations so materials are retrievable fast and consistently
Put away chemicals and supplies in correct storage (ambient/fridge/freezer/flammables/corrosives)
Stage supplies/consumables (vials, tubes, tips, labels, solvents, PPE)

General lab ops support

Keep weighing/receiving areas organized, audit-ready, and safe
Assist with periodic cycle counts and basic inventory cleanup
Follow chemical hygiene and safety procedures consistently

Qualifications

Strong attention to detail; comfortable following SOPs and producing clean records
Comfort with basic lab math (molarity, dilutions) and working carefully with chemicals
Reliable and consistent availability for scheduled shifts (night shift ok)
Basic computer comfort (simple inventory tools)

Required Skills

Prior lab assistant / lab ops / stockroom / receiving experience
Familiarity with SDS, chemical compatibility storage, and labeling norms

Preferred Skills

Ability to lift/move boxes up to 50 lb
Ability to stand at a bench for extended periods

Pay range and compensation package

$28–$32/hour, depending on experience with precision weighing, stock solutions, and inventory discipline (night shift reliability pushes toward the top end).

Equal Opportunity Statement

We are committed to diversity and inclusivity in our hiring practices.

AI-powered autonomous small-molecule synthesis

Onepot.ai builds an AI-enabled platform for automated, multi-step synthesis of small molecules used in drug discovery and materials science. Its system combines robotic hardware with AI agents that use large language models to perform literature review, reaction planning, and experimental analysis, enabling autonomous, high-throughput experimentation. The platform also leverages graph neural networks for reaction prediction, closed-loop optimization for synthesis planning, and foundation models trained on large experimental datasets. This integrated approach differentiates Onepot.ai from competitors by offering end-to-end autonomous synthesis tightly coupled with AI-driven planning and data-driven optimization. The company’s goal is to speed up the discovery and production of new molecules while lowering the time and cost of traditional synthesis methods.
