Founding Content Creator (Copywriter & Storyteller) at Siena

Siena is the Agent of Record for CX, built for consumer brands like Spanx, FIGS, Brooklinen, and Grüns. It runs as a connected multi-agent stack on top of a shared intelligence layer, handling sales, support, social, and voice interactions across the entire customer journey, turning every conversation into actionable insights.

About the Role

The team at Siena is shipping faster than the market can absorb. The words describing their product are falling behind, and the market learns about what they build too late. Currently, launch content is written by the founders and growth team alongside other responsibilities, with no dedicated owner.

With multiple product launches planned for the next two quarters and a Founding Creative Director joining to oversee visuals, Siena is seeking a Founding Content Creator who will own every word Siena puts in front of the market. This includes founder-led LinkedIn posts, social media presence, product launches, blog posts, announcements, and video scripts.

You will decide what we say, where, and how often, and then write it. There is no content team or copywriters to delegate to—you make the thing.

Key Responsibilities

• Own all of Siena’s content—anything published under the Siena name is either written by you or signed off by you.
• Set the strategy for founder-led LinkedIn and company social accounts, write the posts, and own their performance.
• Ship product launches with all necessary content ready: announcements, blogs, social sequences, and founder posts, collaborating with the Creative Director to ensure words and visuals align.
• Write scripts for all product and marketing videos, from launch films to 30-second clips, with the Creative Director bringing them to life.
• Study trends and top-performing posts in the industry and beyond, translating insights into actionable strategies for the team.
• Identify what content drives results and why, doubling down on what works and eliminating what doesn’t without hesitation.
• Leverage AI in every aspect of the work—research, drafting, analysis, and distribution—to move faster than traditional content teams.

Who You Are

The Bar: If you lack any of the following, this role isn’t for you.

• Published writing samples across blog posts, launch announcements, social media, and video scripts.
• Experience shipping content as the sole writer at a company or brand, without a team or copywriters.
• Background in eCommerce or marketing to consumer brands, with an understanding of how their teams operate.

Strong Signal: Not dealbreakers, but these traits distinguish a great hire.

• Professional writing experience predating current AI tools, with the ability to discern between sentences that sound right and those that are truthful.
• Examples of writing that influenced action, such as securing a demo, gaining internal forwarding, or driving a successful launch.
• Integration of AI into every part of your work, with outputs that don’t sound like AI.
• Measurement of your own work and adjustment based on evidence, not just taste.
• Experience running founder-led or executive content and demonstrating its impact.

Nice to Have: Bonus qualifications.

• CX experience in eCommerce, either on the brand side or vendor side.
• Marketing experience with AI, automation, or customer experience products.

Not a Fit If:

• You require a content team or copywriters to produce output.
• You view content strategy as a calendar rather than a point of view.
• You are anti-AI or use AI and ship the first draft without refinement.
• Your best work thrives on slow, protected timelines; this role demands rapid iteration and feedback.
