Siena AI is building the Agent of Record for customer experience—AI-powered customer service automation for consumer brands like Spanx, FIGS, and Brooklinen. The company operates as a fully distributed, global team shipping multi-agent AI systems that handle sales, support, social, and voice across the entire customer journey.
As Founding Content Strategist, you will own all external-facing words for Siena: founder-led LinkedIn, company social accounts, product launches, blog posts, announcements, and video scripts. You are the sole writer and strategist—there is no content team beneath you. You decide what Siena says, where, and how often, then execute it.
Key responsibilities:
- Own all content strategy and execution: if it goes out under Siena's name to market, you wrote or approved it.
- Set and execute strategy for founder-led LinkedIn and company social accounts; write posts and measure impact.
- Ship product launches with complete content packages: announcements, blog posts, social sequences, and founder posts, working closely with a Founding Creative Director to align words and visuals.
- Write scripts for all product and marketing videos, from launch films to 30-second clips.
- Study trends and top-performing content in and outside your category; develop actionable points of view, not swipe files.
- Measure what moves the needle, understand why, and double down or kill underperforming content without being asked.
- Use AI throughout research, drafting, analysis, and distribution to move faster than a traditional content team; your taste is the final filter.
You will work in a high-ownership environment with autonomy to solve problems your way. The pace is fast: multiple product launches over the next two quarters, with feedback cycles measured in hours, not weeks. The team defaults to async communication, writing over meetings, and directness. Low ego, high standards, fast execution.
Requirements:
- Published writing samples across blog posts, launch announcements, social posts, and video scripts.
- Proven experience as the sole writer at a company or brand with no copywriting team behind you.
- Experience marketing to or working within eCommerce consumer brands; understanding of how their teams operate.
- Professional writing experience predating current AI tools; ability to distinguish sentences that sound right from those that are true.
- Demonstrated ability to write content that changed behavior (e.g., posts that drove demos, founder content forwarded internally, launches that landed).
- Fluent use of AI across all parts of your work; output does not read as AI-generated.
- Ability to measure your own work and change course based on evidence, not taste alone.
- Experience running founder-led or executive content with measurable results to show.
Strong signals (not required but valued):
- CX experience in eCommerce, brand-side or vendor-side.
- Experience marketing AI, automation, or customer experience products.
Not a fit if you need a content team, view strategy as a calendar, are anti-AI or ship unedited AI drafts, or require a slow, protected timeline.
