Key Responsibilities

A typical week in this role involves a variety of tasks, including but not limit to:

Garden Care & Facility Maintenance

• Landscape Upkeep: Maintain lawn areas, trails, and diverse garden beds using traditional gardening tools (shovels, rakes, hand pruners, weeders).
• Property Presentation: Keep walkways and trails clean and safe by clearing weeds, fallen fruit, debris, and animal droppings. Spread mulch and soil to protect plants from sun exposure.
• Water Management: Monitor and maintain garden irrigation, utilizing sprinklers and hoses to meet the watering needs of various plant species across changing seasons.
• Animal Care: Support daily care for our on-site animals (including feeding, watering, and maintaining habitats for chickens and ponds).
• Daily Facility Care: Take care of the small daily details that keep the property running smoothly, including routine trash removal, and basic restroom upkeep.
• Operations Support: Assist with the setup, parking, and teardown for events and classes held at the Learning Center, and occasionally assist guests with parking.

Field Assistant ("Puller" Duties)

• Arborist Support: Accompany our Certified Arborists/Technicians in company trucks to client properties to assist with advanced tree treatments.
• Site & Hose Management: Safely manage up to 400 feet of treatment hose, ensuring it moves efficiently without damaging clients' property, planters, or landscapes.
• Equipment & Safety: Assist with adjusting hose/pump pressure, monitor the area for pedestrian safety, and maintain a clean, highly organized mobile job site.

What We Are Looking For

• Proactive Ownership: We practice a decentralized style of leadership—we value "go-getters" who take complete initiative to keep shared workspaces, shop tools, and grounds organized.
• Active Stamina: Comfort working outdoors year-round in all weather conditions (harsh sun/heat, rain, wind). Ability to stand, bend, kneel, walk long distances on uneven terrain, and frequently lift 30 lbs (and occasionally up to 65 lbs).
• Safe Drivers: A valid driver's license and a clean driving record are required to operate company-provided trucks (similar to an F-250) for errands and field jobs.
• Environmental Comfort: Comfort working in a natural environment (around dust, dirt, mud, plant pollen, and friendly family dogs) and a safety-first attitude when working near traditional or organic plant treatments.
• Equipment & Mechanical Comfort: Highly comfortable operating and working around power tools, groundskeeping machinery, and farm/utility equipment. You should be ready to step in and assist with operating equipment like lawnmowers, tractors, golf carts, and utility vehicles as needed.

Compensation, Benefits & Schedule

• Pay Range: $18.00 – $21.00 per hour (Depending on Experience)
• Job Type: Full-Time (40 hours/week)
• Benefits: Vacation and Sick Pay, Paid Spring & Summer Holidays, Health/Vision/Dental Insurance, Employee Discounts, and Paid Training.
• Schedule Flexibility: A flexible schedule is preferred to support seasonal demands. Standard garden shifts can be chosen to start between 5:00 AM and 8:00 AM (weekends preferred).
• Hours may adjust based on seasonal needs or Puller demands, including earlier start times to beat the summer heat or to match the arborist's schedule (typically Monday–Friday, 6:00 AM to 2:00 PM).
• Occasional schedule adjustments may be required for special events.
