From the employer

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.

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
