Job Description

Responsibilities

  • Rapidly turn cold contacts into qualified leads with email and social campaigns, newsletters, and curated content that move prospects from first touch to a sales conversation.
  • Set up, run, and optimize paid ad campaigns across LinkedIn, Meta, Google, X, and other relevant channels, owning targeting, creative, A/B testing, and budget to lower cost per qualified lead.
  • Build self-serve website content, such as product pages, application notes, white papers, FAQs, and explainer videos, that lets prospects educate themselves and convert without waiting on sales.
  • Produce a high volume of polished, on-brand assets, including flyers, one-pagers, social graphics, short-form video, and conference materials, using AI-native design workflows to go from brief to final in hours, not days.
  • Write clear, technically accurate copy and documentation, partnering with scientists and leadership so every claim is correct.
  • Build reusable templates, brand guidelines, and an organized asset library so quality holds as output scales.
  • Track the performance of every asset and campaign, including engagement, conversion, and lead quality, and iterate quickly in partnership with the Growth Engineer.
  • Own projects end to end and perform other duties as assigned in support of company growth.

Requirements

  • Bachelor's degree and 2+ years creating marketing or technical content, pairing strong visual design and writing with real scientific or technical depth; experience in biotech, pharma, or other regulated industries is a strong plus.
  • A visual portfolio demonstrating your design and writing work and the results of campaigns you ran, such as ad campaigns, social content, video, flyers, or technical documents.
  • Daily, hands-on use of AI-native design tools and workflows (e.g., Claude Design, agentic design, AI image and video generation) to take assets from brief to polished, on-brand final in hours, not days. Canva or Adobe skills are a plus, but not sufficient on their own.
  • Track record of campaigns across email (e.g., HubSpot) and social channels (e.g., LinkedIn, X, TikTok, Meta), plus technical collateral (flyers, application notes, white papers), with measurable outcomes you can show, such as engagement, open and click through rates, leads, or pipeline influenced.
  • Hands-on experience setting up and managing paid ad campaigns (e.g., LinkedIn, Meta, Google, X), including audience targeting, creative testing, budget management, and optimizing for cost per qualified lead.
  • Experience creating short-form social video and product explainers, including AI-generated video, that earn attention and shares while staying technically and scientifically accurate.
  • Ability to manage multiple priorities, move quickly, and maintain strong attention to detail in a fast-paced startup environment, with a demonstrated ownership mentality and strong follow-through.
  • Must reside within a reasonable commuting distance of San Carlos, CA.

Benefits

  • Paid Time Off: Unlimited PTO, plus company-recognized holidays.
  • Health Benefits: Medical, dental, and vision coverage.
  • DoorDash Credit: $25 credit for lunch and dinner while working in the office.
  • 401(k) Plan with company matching, subject to plan terms.
  • Company-paid life insurance.
  • Stock option package.
