Content & Social Media Intern

Part time position starting on Sept 1 in SF - role will be closed once a suitable candidate is found
 

Hi! 👋
 

My name is Sophia Millar. I’m the Co-Founder and CEO of Sonibel Instruments. We’re a hardtech startup with the mission of modernizing manufacturing so we can keep up with the world’s growing demand for urgent critical infrastructure, from skyscrapers to naval ships to grid expansions.

At Sonibel Instruments we work hard. You’ll get:
 

• ⚙️Autonomy and freedom. You pick your own projects, set your own goals, and work the hours you want at our SF office
• 🔧Only important work. We’re a small team so there’s no busy work. You’ll be leading mission critical projects from the ground up
• 🤖Fast, hands-on work across functions. Every week comes with new problems, new skills, and real things to build
• 💡Decisions based on data. Everyone at every level is trusted to make decisions and experiment
• 💰Competitve compensation through salary and equity (if you join us full time) so you’ll own your work
• 🦾Leaders who own their mistakes, actively seek feedback to identify & solve them, and are pretty experienced

In the past 10 months, we’ve:
 

• 💸 Raised over $1.6M USD
• 👩‍🏭Invented and patented a first-of-its-kind system
• 🎉Landed major customers including the Navy!
• 🏆Had inbound requests from the biggest manufacturers in the world wanting to use our tool including Caterpillar, John Deere, Exxon, Komatsu, L&T, and more
• 🎓Graduated from the Creative Destruction Lab
• 😎And we just started growing the team past the 3 founders  
   

We’re building the first ever complete real-time quality control system for welders. Our edge device is powered by acoustics: it listens to welds in real-time and alerts the welder if there’s a defect. This can cut total project costs by 30% and save 2 months on a year-long timeline, making it cheaper and faster to build urgent critical infrastructure. With a $1.5 trillion manufacturing backlog and huge labour shortage, we’re in high demand.
 

You’ll be doing and learning to:
 

• 🎥 Own founder-led content across LinkedIn, Instagram, YouTube, X, and other channels, from content strategy and ideation through writing, filming, editing, posting, and distribution
• 📈 Develop and test social media strategies, using audience and performance data to understand what works, improve content, and grow reach and engagement
• 🏗️ Turn what’s happening inside the company - product development, customer work, industry news, events, and founder perspectives - into compelling content people actually want to watch, read, and share
• ✍️ Build a consistent voice and content system, including recurring formats, content calendars, and workflows that let us publish high-quality content frequently

Overall, we want someone who can work closely with the CEO to turn raw ideas and what’s happening day-to-day at the company into great content, while continuously experimenting with how we can grow our audience across social platforms.
 

The ideal candidate:

• 🚀 Wants the pace and intensity of a fast-growing, well-funded SF startup and is prepared to help the company move quickly
• 🌎 Is excited to tell the story of a new industrial technology changing how major critical infrastructure is built
• ✍️ Has strong taste and can turn raw ideas, technical work, customer stories, and company updates into content people actually want to watch, read, and share
• 🎥 Is comfortable directing, writing, filming, and editing content, especially short-form video and founder-led social
• 📱 Understands what works across platforms like LinkedIn, Instagram, YouTube, and X, and pays attention to how content performs
• 🧠 Can take a rough idea or moment inside the company and independently turn it into a strong finished piece of content
• 📈 Likes experimenting with formats, hooks, topics, and distribution, then using performance data to improve what we make
• 🛠️ Uses AI and modern content tools to move faster without sacrificing quality
• 🌟 Bonus points:
  • You’ve grown a social media account, personal brand, or company audience
  • You have a portfolio of content you’ve written, filmed, or edited
  • You’ve created content about technical, industrial, scientific, or otherwise complex topics
  • You’ve worked closely with a founder or at an early-stage startup
