Job description

The role

At Mach9, the Community Marketing Manager will create new ways for our customers to connect with Mach9 and with one another. Customers are already asking for a place to exchange ideas, get support, and learn from their peers; you’ll build that space and give them useful reasons to return.

This role is ideal for a community builder who has created sustained participation, builds trust easily with users, and can turn those relationships into programs people value.

You’ll own the community experience across online conversations, in-person events, and the relationships that follow. Success means a network that increasingly grows itself: members answering members, advocates bringing in their peers, and new customers arriving through referrals.

Where you will make an impact

• Choose the right home for Mach9’s customer community, then design how it works: onboarding, moderation, and the activities that keep people coming back
• Build sustained participation by starting useful conversations, answering questions, and helping members learn from one another — then turn what works into repeatable playbooks
• Develop customers into advocates, contributors, speakers, and sources of referrals
• Plan and run recurring meetups, user groups, advisory sessions, and other customer programs, owning recruitment, programming, logistics, and follow-up
• Build partnerships with professional organizations like state surveying associations to create joint in-person events and grow a broader friends-of-Mach9 network
• Write customer stories and promote events in the customer newsletter and social content
• Advocate for customers and bring the questions, feedback, and ideas shared by customers to the product, engineering, and customer success teams

What you bring

• Experience building or growing a customer, professional, alumni, membership, or interest-based network
• Evidence that you have created repeat participation, not only promoted one-time events
• The ability to earn trust and build lasting relationships with specialized users
• Clear writing and confidence communicating through online groups, email, social media, and live events
• Strong creative judgment and the ability to turn customer activity into engaging content
• The organization and independence to take programs from initial concept through execution and follow-up
• Curiosity about surveying, civil engineering, geospatial technology, and infrastructure

Bonus experience

• Experience recruiting attendees or growing participation without relying on an established brand
• Photography, graphic design, filming, or video-editing skills
• Prior work in construction technology, industrial software, engineering, GIS, or a related field
