We'd love to tell you more in person.

Join us at SKELAR and help build the next big everything!

Why this role exists:

We already work with several promoters — and it’s producing results. But the process behind it is informal: no structured onboarding, no systematic outreach, no scalable framework. That’s what this role fixes. We need someone to take what exists, build a real operating system around it, and then use that foundation to grow the network.

What does ownership mean here:

You own the channel and the revenue it produces. You’ll start by getting your hands around what’s already working — understanding the current promoter relationships, identifying gaps, and building the processes that make it repeatable. From there, you expand: more partners, better formats, a bigger team. You’re not inheriting a machine — you’re building one from rough parts.

What you’ll do:

• Audit and systematize existing promoter relationships — document what’s working, fix what isn’t, and build the processes to make it scalable
• Design and own the full partner lifecycle: outreach, negotiation, onboarding, activation, and performance tracking
• Recruit and onboard new creators, influencers to grow the network
• Launch and run webinars, podcasts, interviews, sponsorships and content collaborations
• Hire and manage a team as the channel grows
• Own influence channels revenue

What we are looking for:

• Hands-on experience working directly with influencers and content creators
• Experience with U.S.-based influencers
• Experience building or structuring partnership processes — not just executing someone else’s playbook
• A track record of growing partnership revenue independently
• Ability to own results end-to-end
• Fluent English, written and spoken
• High energy, drive, and a bias for action — this role rewards people who make things happen

Nice to have:

• Background in real estate, lead gen or SaaS
• Experience attending or presenting at industry conferences and live events

Working hours

Since our partners and influencers are US-based, you’ll need to align part of your schedule with US time zones — for example, joining webinars or calls with partners/influencers when needed. Outside of these specific commitments, you have full flexibility to manage your own hours.

What you get

• Existing relationships to build on — you’re not starting from zero, but you’ll shape everything from here
• A direct line to leadership with full visibility into business metrics
• The chance to design the function your way, without an inherited mess to undo
• Full remote work
• 24 paid vacation days per year
