About the Job

Requirements

  • A high school diploma or equivalent is required.
  • At least 3 years of experience in agriculture, horticulture, plant breeding, seed production, or related fieldwork is required; internship experience is considered.
  • Strong attention to detail and steady hands for fine, flower-level work, including emasculation and hand-pollination.
  • Ability to follow precise, protocol-driven procedures and maintain accurate identity-preserved records.
  • Comfort working in greenhouse, screenhouse, and/or open field environments.
  • Ability to work flexible hours, often early morning, because flower receptivity and pollen viability are time-sensitive.
  • Ability to stand, bend, and work at bench or plant height for extended periods.
  • Ability to lift up to 30–50 pounds.
  • Valid driver's license with a clean driving record.
  • Ability to travel 25% to different TPS production sites, sometimes for a week or more.
  • Ability to perform fine, repetitive hand movements for extended periods; work at bench and plant height or bend/kneel in open field plots; work in warm, humid greenhouse conditions and variable outdoor weather; repeatedly walk plot or greenhouse rows; and work early morning shifts during active flowering and pollination windows.

Responsibilities

  • Execute seed production planting at appropriate TPS production locations across U.S. planting sites.
  • Collect detailed data, keep production records updated, and report information as it happens.
  • Follow pollen collection and seed production standard operating procedures to ensure high-quality outcomes.
  • Collect pollen from designated male parent plants at the correct flowering stage, ensuring viability through fresh collection and proper storage and temperature control.
  • Perform hand-pollination by applying pollen to female flowers according to prescribed crossing designs.
  • Immediately tag and label each pollinated flower or truss with cross ID, parent line, and date to maintain traceability through berry set and harvest.
  • Monitor flowering synchrony between male and female parent plants and flag timing mismatches to breeders or supervisors.
  • Track pollination success rates, fruit (berry) set, and flower drop, recording data in field books or digital data collection tools.
  • Monitor berry development and maturity, including color change and softening, to determine correct harvest timing.
  • Hand-harvest mature berries by cross or truss while preserving identity and avoiding cross-contamination between crosses.
  • Assist with berry processing by crushing or macerating berries, fermenting pulp, and washing to extract true seed.
  • Dry, clean, and package extracted true potato seed lots according to protocol, ensuring accurate labeling for storage and germination testing.
  • Support seed viability and germination testing procedures as needed.
  • Assist with planting, transplanting, and maintenance of parent clone plots in field, greenhouse, or screenhouse settings.
  • Conduct regular field and greenhouse inspections to monitor plant health, flowering stage, and pest and disease pressure.
  • Rogue off-type or diseased plants to protect the genetic integrity of parent lines.
  • Support isolation requirements between crossing blocks to prevent unwanted pollen contamination.
  • Maintain irrigation, staking, and general crop upkeep for parent clone plots.
  • Operate small field and greenhouse equipment as needed, including sprayers, irrigation systems, and hand tools.
  • Maintain meticulous, organized records in compliance with company and regulatory traceability standards.
  • Help coordinate seasonal labor during peak flowering, pollination, and berry harvest periods.
  • Follow all safety protocols, including proper personal protective equipment use when handling crop protection products and performing seed processing and field crop tasks.

Desired Qualifications

  • A bachelor's degree in agriculture, plant science, or seed production background is preferred.
  • An associate's or bachelor's degree in Horticulture, Agronomy, Plant Breeding, Botany, or a related field is preferred.
  • Prior experience with potato production, true potato seed or hybrid seed crossing, or other hand-pollinated crop systems.
  • Familiarity with breeding nursery protocols, cross or pedigree tracking, or germplasm databases.
  • Experience with pollination, seed extraction and fermentation processes, and seed-cleaning equipment.
  • Experience with greenhouse pest and disease scouting and integrated pest management practices.

About the Company

Ohalo

Seed-based accelerated crop breeding platform

Ohalo Genetics develops seeds using Boosted Breeding, a method that makes plants pass on their entire genome to offspring, enabling asexual reproduction through seeds. How it works: by altering the reproductive process, the offspring are genetically identical to the parent, producing true seeds that carry the full parent genome. This allows rapid development of new crop varieties with desirable traits, shortening breeding cycles from about 10–12 years to only a few years. What sets it apart: it targets a wide range of crops (potatoes, corn, berries) and collaborates with other agricultural companies to develop and commercialize new varieties, focusing on predictable, genotype-stable outcomes. What the company aims to achieve: increase crop productivity and resilience to changing environmental conditions, helping improve the food supply chain by delivering better-yielding, more reliable crops.
