Job description

ABOUT

Arceus is building the AI-native law firm for the next generation of category-defining companies.

We help fast-moving companies move contracts through legal at record speed, with transparency, predictable pricing, and exceptional quality.

We are hiring a Founding Content & Social to own how the world hears about us. You will capture, write, edit, film, and publish all of our content to turn our company and team into the most recognizable voices in startup legal.

This is an in-person role based in San Francisco.

THE OPPORTUNITY

We are seeing incredible demand for our product. The market is open for us to capture and emerge as the winners in this new category.

This is a rare chance to:

• Define the voice of a generational law firm before anyone else does

• Own social, video, and brand content end to end

• Ghostwrite for team members whose audiences you will grow from the ground up

• Build the content engine that turns demand into qualified meetings

• Own meaningful equity in a company with category-defining ambition

• Take on responsibility far beyond your years of experience

WHAT YOU’LL OWN

We have an extraordinarily high bar and expect relentless, consistent execution. You are expected to show up every day with urgency, ownership, and a positive attitude, and to deliver results consistently.

• Own the social strategy and the calendar across LinkedIn, X, and other social platforms

• Ghostwrite for our team and turn ideas into posts that generate demand

• Capture and edit video content that creates more awareness and demand

• Design graphics, carousels, thumbnails, and event assets for content

• Run the brand accounts and build them into a real audience

• Move fast on reactive moments and turn them into content

• Amplify every launch, event, and conference

• Measure everything and kill what isn't working, with a weekly report on what performed and what changes because of it

IDEAL CANDIDATE

You are a full-stack content create. You write, capture, edit, design, and publish content without needing support from others. You have a few years of experience and operate like a true owner: ambitious, curious, resilient, and relentless about getting things done.

• You write thoughtful content that generates demand

• You can make a clean graphic or carousel in Figma, Canva, or ChatGPT

• You can shoot decent video on a phone and cut it in CapCut, Premiere, or Descript

• You are online and understand what's performing on LinkedIn and X each week

• You can hold three voices in your head at once and write convincingly in each

• You are comfortable measuring your own work and killing what isn't performing

• You take complete ownership of outcomes and find a way to deliver

• You are exceptionally organized and strong at coordinating and planning

• You take on challenges far outside your comfort zone

• You hold yourself to an exceptionally high standard and expect to keep raising it

• You want to build one of the most exceptional content engines ever created

WHAT SUCCESS LOOKS LIKE

• Day 7: You’re publishing content that is generating demand

• Day 14: You’re analyzing what’s working, hypothesizing new angles, and scaling content

• Day 30: Company accounts are growing and you’ve built a v1 content engine

• Day 60: You own a repeatable content engine and continuously amplify and scale it

EXPERIENCE

• 2-4 years creating content at a startup, agency, or for a creator; bonus if you’ve ran a content agency

• A portfolio or accounts you can point to; we care far more about what you've published than where you worked

• You are relentless, and will work 12+ hours per day, 6 days a week (yes, including weekends)

• You thrive in an environment with an exceptionally high bar, where everyone is expected to go above and beyond

• You own outcomes from start to finish and have a track record of never dropping the ball

• You move at an incredible pace and have insane urgency to deliver results

• You respond to setbacks with resilience, resourcefulness, and a determination to find a way

COMPENSATION & BENEFITS

• Competitive base salary commensurate with experience: $110,000 – $150,000

• Competitive equity in the company

• Comprehensive health, dental, and vision coverage

• Camera, editing software, and whatever gear you need to do this well

• Catered lunches and dinners at the office

• Wellness and learning stipends

• Option to contribute to a 401(k)

• Unlimited PTO
