Social Content Writer

Social Content Writer

Our job at Signal Theory is to help people and brands connect in more meaningful ways through strategically sound creative solutions. A content writer at Signal Theory is, above all else, responsible for consistently bringing smart, original and breakthrough thinking to any project — paired with a deep understanding of what makes creative work great.

We're seeking someone with excellent conceptual and copywriting skills who doesn't just love the content space — they live in it. A content writer at Signal Theory needs to process information and feedback from clients and colleagues effectively, and articulate ideas, creative choices and strategic direction with clarity and conviction.

At Signal Theory, a content writer reports to a Group Creative Director. Every day, you'll work with an integrated team of strategists, art directors, copywriters, content producers, account leaders, analysts and developers to shape the bigger brand picture for the clients you work with.

A content writer should be accomplished in collaboration, communication, platform fluency, and — most importantly — creative thinking and word-slinging. Above all, a content writer must live, breathe and love the social space.

Responsibilities

A content writer will:

  • Actively participate in group discussions and creative meetings.

  • Write platform-native content for Instagram, TikTok, Facebook, X/Twitter, LinkedIn, YouTube Shorts, Threads and emerging channels — understanding the distinct voice, format and constraints of each.

  • Concept and write across formats: captions, short-form video scripts, reels, carousels, stories, ad copy and campaign-level social activations.

  • Collaborate with art directors, designers and content producers to bring ideas to life across visual and written formats.

  • Use performance data and engagement insights to inform and iterate on copy strategies.

  • Stay current on platform algorithm changes, emerging formats and cultural trends — and bring that knowledge to the work.

  • Work with outside resources including production companies, talent and audio production as needed.

  • Help create, organize and present effective creative presentations.

  • Mentor and guide associate copywriters when the opportunity arises.

  • Demonstrate fluency with AI tools as part of a modern creative workflow, while keeping the thinking sharp and the voice human.

  • Manage time effectively to meet responsibilities and deadlines across multiple accounts.

  • Maintain a solid working relationship with proofreaders and pay close attention to detail.

  • Explore multiple solutions to any given problem and edit your own work with a critical eye.

  • Eagerly volunteer for any targeted need or opportunity.

Exceptional Benefits Include


  • A portfolio that demonstrates strong social-first creative thinking — concepts, campaigns and platform-native content that you're genuinely proud of.

  • Deep familiarity with how content performs differently across platforms and why.

  • Experience writing for short-form video (TikTok, Reels, Shorts) and long-form social formats alike.

  • An understanding of brand voice and the ability to shift tone across categories and audiences.

  • Strong instincts around cultural relevance and trend-aware content.

  • The ability to work independently and as part of a collaborative team.

  • Applicable experience is valued — a strong portfolio and sharp creative instincts matter more than years on a resume or a specific degree.

Exceptional Benefits Include

Exceptional benefits include:

  • Access to online learning platforms to continue honing your craft.

  • Up to $500 a year to put toward qualified wellness expenses, like your gym membership.

  • After one year, reimbursement of up to 50% of tuition costs for approved continuing education.

  • After eight years, a four-week paid sabbatical, plus a $750 reimbursement for international travel.

Of course, we also:

  • Provide health, dental and vision insurance.

  • Offer salaries commensurate with experience.

  • Offer both traditional and Roth 401k plans with employer matching.
