Marketing:

Schedule and publish social media posts (Canva)
Write captions for project photos and update the website with case studies
Send a monthly newsletter and request Google reviews / testimonials

General admin:

Inbox triage — sort, flag urgent items and draft replies for approval
Book and confir ---------- etings and site visits
Track subcontractor licences and insurances (compliance register)
Keep job folders and documents organised in Wunderbuild

Systems (we build this together):

Help set up and build out Wunderbuild as our new job-management platform

WHAT WE'RE LOOKING FOR

Xero experience (essential)
Excellent written English, rarely a spelling mistake
Strong attention to detail and care for accuracy
Comfortable with Google Sheets / Excel and cloud file management
Basic Canva skills
Self-motivated and reliable, with a proper home office and stable internet
A few overlapping hours with New Zealand mornings
Keen to learn new software and help document processes
Nice to have: construction/trades experience, Wunderbuild or similar, a CRM

WHAT WE OFFER

Flexible working hours
Your birthday off as a paid holiday
Local Philippine public holidays plus our NZ Christmas / New Year break, all paid
Training, support and a personal development budget
Performance-based bonuses
Work from home, with a genuine path to full-time
