Treesources is seeking an experienced Estimator who is also a seasoned, hands-on arborist tree trimmer. This is a dual role: you will scope and estimate production-arboriculture work and strengthen the team with production arboriculture support — assessing each job through the eyes of someone who has climbed, rigged, and made the cuts. You will conduct site visits, produce accurate and well-documented estimates, and build complete work packets that crews mobilize on without guesswork — and you will be able to step into the field to demonstrate, train, or support crews on the tools when the work calls for it. This is a high-impact role for a working arborist who estimates with precision because they know firsthand what the job takes.
Key Responsibilities
- Conduct site visits to assess trees, access, hazards, and site conditions from a working climber/trimmer's perspective, and translate them into accurate, buildable project scopes.
- Prepare complete, defensible estimates of labor, crew hours, equipment, materials, traffic control, and debris disposal for production arboriculture work (pruning, removals, cabling/bracing, and related services).
- Produce comprehensive job hand-off packets for field crews — documented scope, site maps, photographs, annotations, and clear work instructions — so each mobilization is fully prepared.
- Perform and lead hands-on tree work as needed — climbing, aerial-lift, pruning, and removals to ANSI A300 / Z133 standards — to set scope, demonstrate technique, train crews, and support production in the field.
- Build and maintain estimates and work orders in the company's field-service management system (ArboStar), keeping it the single source of truth for every job.
- Track estimated-versus-actual scope and hours on completed jobs, and use the findings to continuously improve estimating accuracy.
- Coordinate closely with production crew leads to hand off work cleanly and incorporate field feedback.
- Support scheduling by translating sold work into clear prep, equipment, and crew requirements ahead of each week.
- Structure estimates to support accurate, timely billing and project cash-flow tracking.
- Maintain a fast, reliable estimate turnaround — target of 1–2 business days.
Focus Areas
Estimating responsibilities center on production arboriculture (residential, commercial, and institutional tree work) as the primary focus, expanding over time into tree relocation and tree health care as the role develops.
Qualifications
Required
- 5 - 10 years of hands-on production tree-care experience — a seasoned working arborist / tree trimmer with real climbing, aerial-lift, pruning, and removal experience.
- Hands-on experience estimating production arboriculture or comparable tree-care work.
- Strong ability to assess a site and produce accurate, well-documented scopes, crew-hour estimates, and pricing.
- Working knowledge of ANSI A300 (tree-care standards) and ANSI Z133 (safety), and the ability to work safely around hazards.
- Excellent organization and documentation skills — able to produce clear, mapped, and photographed work packets crews can execute from.
- Comfort working in a field-service management or ERP system and maintaining accurate, up-to-date records.
- Ability to manage a steady pipeline and consistently meet a 1–2 business day turnaround without sacrificing accuracy.
- Valid driver's license with a clean driving record — no suspensions within the past 3 years.
- Willingness to travel to job sites primarily across Miami-Dade County, and as needed throughout South Florida; able to meet the physical demands of field tree work.
Preferred
- ISA Certified Arborist — or the experience and willingness to attain it while employed (we support and build in the certification).
- ISA Certified Tree Worker (Climber Specialist) or an equivalent recognized tree-trimmer credential.
- ISA Tree Risk Assessment Qualification (TRAQ).
- Knowledge of Miami native trees and tree species commonly found in South Florida.
- Familiarity with Miami-Dade County and City of Miami tree-permitting processes.
- Familiarity with maintenance of traffic (MOT), crane and rigging operations, and related cost factors.
- Aerial-lift / EHAP certification and chainsaw / rigging proficiency.
- Experience with ArboStar or similar tree-care/field-service software.
- Bilingual English/Spanish.
What Success Looks Like
Within your first 90 days, you will be fully fluent in the company's production arboriculture services and estimating system, delivering accurate estimates and complete, well-documented job packets to field crews on a consistent 1–2 business day turnaround — with estimates that hold up in the field because they're set by someone who can do the work, and estimated-versus-actual accuracy steadily improving job over job.
