Job description

Be Hub's voice where our contributors live: Instagram, TikTok and WhatsApp, in Portuguese and English.

Robot foundation models learn physical behavior from human demonstration, and real-world data has become a critical bottleneck in embodied intelligence. Hub provides real-world training data to frontier AI labs and robotics companies. Our network of 150,000+ contributors in 150 countries records first-person footage of real work, at home and at work, and gets paid for every approved hour. Backed by Y Combinator, our mission is to advance embodied AGI through real-world data and research.

The Role

As Community & Social Media Manager you are Hub's voice where our contributors live: Instagram, TikTok and WhatsApp. You make the content, run the channels and keep the community informed and excited, in Portuguese and English.

What You’ll Own

Strategy first: understand Hub's positioning and objectives, then build our social media strategy, branding and tone of voice.

Calendar: a social media calendar across all platforms, always-on content plus campaigns, in line with the company's objectives.

Content, every day: short videos (Reels, TikToks), visuals and subtitles, from the idea to the post.

Channels: Instagram, TikTok Brazil and US, plus Hub news repurposed for X and LinkedIn.

Community: our WhatsApp, Discord and Telegram channels in Portuguese, English and Spanish. You answer comments and DMs fast, post clear updates on payouts, new tasks and rules, and shut down scams and false rumours.

Creators and UGC: find, brief and manage creators, run lives with them, and turn every live into a week of content.

Campaigns: app launches in new countries, giveaways with clear public rules, community challenges, with our community and support lead.

Numbers: a weekly report on followers, engagement, signups from social and community sentiment.

Examples of What You’ll Work On

We open the Hub app in the US next week. Build the launch content plan for TikTok and Instagram, make the first 10 videos and get them live.

A rumour that payouts are blocked is spreading in the comments and WhatsApp groups. Get the facts from the team, post a clear update within the hour and answer the comments.

We go live with big Brazilian creators on Thursday. Write the brief and the run of show, then cut the live into clips for the whole week.

Our Instagram profile and highlights confuse new visitors. Rebuild them so anyone understands Hub, and how to start earning, in 10 seconds.

The Profile

3+ years running social media and community for a consumer app, marketplace or creator brand. Experience in Brazil is a big plus. A portfolio with numbers you can point to. We look for outliers with outstanding achievements and grit.

Brand and strategy.

You know how to develop branding, tone of voice and a content strategy in line with a company's positioning and objectives.

Fluent English, spoken and written. Portuguese is a big plus (native is even better, but not a requirement). Spanish is a plus.

A creator yourself. You shoot, edit and design at a daily pace: CapCut or Premiere, Figma or Canva, and GenAI video tools like Higgsfield.

At home in social media culture. TikTok trends, memes, creators and community groups. Knowing Brazilian internet culture is a big plus.

Calm and clear under pressure. Negative comments, crises and scams don't scare you.

Proof of success. Accounts you grew, videos that took off, communities you built, and how you did it.

AI native. GenAI for video, images, subtitles and translation; agents to monitor comments and build your reports.

Big sense of ownership. The channels are yours: content, replies, results.

Passionate about technology. You follow AI and robotics because you love it, not because the job asks.

Culture

Small core team by design. Y Combinator + San Francisco pace.

High accountability. Channels owned end to end: plan, create, publish, reply, report.

Everyone runs AI agents, not just engineering.

Constant, proactive communication. Slack, huddles, short stand-ups. No black box.

Urgent issues get handled when they come up, not when it's convenient.

Tools and Stack

CapCut or Premiere, Figma or Canva.

Higgsfield and other GenAI tools for video, images and voice.

Instagram, TikTok, WhatsApp Channels, X and LinkedIn, with their native analytics.

Agents for comment monitoring, translation (PT / EN / ES) and weekly reporting.

What We Offer

$36,000 to $48,000 yearly base.

Early community and content hire at one of the fastest-growing Y Combinator startups.

Path to build and lead Hub's community and content team as we launch in new countries.

Remote from anywhere in the world. Presence in our São Paulo or Paris office is a big plus.

Direct work with the founders.
