About the role

The future of Marketing is 1-1 hyper-personalized messaging. However, marketers spend multiple cycles setting up an "octopus" on CRM journey builders to manually write content for each persona and segment. Further, A/B testing is sequential and takes weeks to show results.

We drift away from the old school A/B testing world to dynamic testing. Companies can test 100+ messaging variants within a month, let AI optimize traffic for winning variants, and walk away with insights without operational setup overhead for every A/B test. We put companies in a state of continuous "always-on" testing.

What You'll Do

  • Plan and publish daily across LinkedIn, X, and emerging channels.
  • Build the engine — editorial calendar, repeatable formats, brief templates, review loops.
  • Turn customer wins, product updates, and category shifts into stories worth reading.
  • Track reach, engagement, and pipeline contribution; report weekly on what's working and what to change.
  • Partner with founders, sales, and product to find the best raw material.
  • Experiment with formats — short-form video, threads, carousels, newsletters — and double down on what performs.

Who You Are

  • A recent graduate or current student (0–2 years of experience); any academic background.
  • A storyteller who can take a dry product update and make it land.
  • Outcome-oriented — you measure success by reach, engagement, and pipeline, not by posts shipped.
  • Data-driven — comfortable in analytics dashboards; reads the numbers before trusting the vibe.
  • Systems-oriented — you build templates, calendars, and dashboards so the work scales beyond one person.
  • Driven — self-directed, fast, and not afraid to publish in public.
  • A strong writer in English. A portfolio (personal account, student publication, side project) is a plus.

Bonus

  • Grew a personal or brand account.
  • Fluent with AI tools for content.
  • Basic Figma/Canva and short-form video editing skills.

What You'll Get

  • Direct mentorship from founders and senior marketers.
  • Full ownership of the content function from day one.
  • Competitive compensation.
  • A fast, 100% onsite team in San Francisco where learning compounds.

How to Apply

Respond to this posting with your resume and one of the following:

  • A piece of content you wrote and shipped that you're proud of, plus a note on what it drove.
  • A 200-word teardown of any brand's social presence — what's working, what isn't, what you'd change.
  • About the interview

    • 30 min chat with the CoS and founders
    • 2 hour interview loop
    • References Checks
