The Role
You own fonio's social presence in Brazil, end to end. Strategy, ideas, copy, production, editing, posting.
Instagram is where we start. LinkedIn comes right after, including building personal brand content for our leaders here. Wherever else our audience actually pays attention, you make the call and we go.
We sell to businesses that run on the phone: clinics, agencies, dealerships, condo administrators, insurance brokers. Thousands of calls, often with no big IT team, and plenty of doubt about whether AI can really handle a customer on the line. Some of them have never seriously considered it. Most of the ones who have are skeptical. Your job is to turn that skepticism into curiosity, and curiosity into a demo request.
You'll be the first social hire in Brazil, which means you're building the playbook, not inheriting one.
What you'll do
Own our Brazilian social channels from strategy to publishing: formats, copy, production, editing, community
Build content that travels: saves, shares and comments from people who actually buy, not vanity reach
Turn product and customers into stories: real use cases, real calls, real businesses
Build fonio's voice on LinkedIn, including personal brand content for our leaders in Brazil, so we own the conversation about voice AI here
Brief and coordinate freelancers, editors and creators when we need extra hands. Occasional, not the core of the job
Work alongside performance marketing on creative that converts, and know when you're making brand content and when you're making an ad
Contribute across the rest of marketing: webinars, email, launches, campaign ideas and whatever we need to grow
What you bring
3+ years creating social content, ideally B2B or for a brand that had to make an unglamorous category interesting
Fully hands-on: you write, shoot, edit and publish yourself. You don't need an agency or a studio to ship
Native Brazilian Portuguese with a great ear for tone: casual, human, never corporate filler
Strong English, non-negotiable. Most of the company sits in Vienna
Analytical: you look at what performed, form a hypothesis, and test again
Genuinely curious about AI and where this space is going, not just following it from a distance
High ownership and short feedback loops. You bring ideas instead of waiting for briefs
Comfortable being bold in public. You've made something that got attention and you know the difference between bold and cringe
Nice to have
Video editing and motion skills
Experience producing creative for paid social
Experience building personal brands on LinkedIn
What we offer
Competitive salary package depending on experience, including equity
CLT/PJ contract, whichever works better for you
Health insurance
30 days of paid vacation
Hardware of your choice
Regular team offsites
Work from our Campinas office, on-site, with an ambitious team
Hiring process
15 min intro call
30 min BR fit call
30 min skills call
15 min culture call with our founders
