Marketing Lead

ABOUT THE ROLE This is a zero-to-one brand-building role at an early-stage ambient AI startup, sitting at the intersection of Product, Engineering, and a global marketing team. You'll own US brand execution end-to-end — defining narrative, voice, and market position in a crowded AI space — while feeding real audience signal back into what the company builds next. WHAT YOU'LL DO - Identify and validate the core early-adopter audience through lightweight experiments, qualitative interviews, and community signal-reading. - Develop a sharp, defensible brand narrative and voice that resonates with AI-native and power-user segments. - Write, test, and iterate on marketing copy, positioning, and brand identity directly — not hand off to an agency. - Run messaging experiments across audience segments and double down on what demonstrably works. - Own channel and sequencing decisions, determining which platforms deserve a real presence and when. - Collaborate with Product and Engineering as an upstream stakeholder, translating audience insights into roadmap input. - Coordinate with the global branding team to keep US execution aligned as the brand evolves. WHAT WE'RE LOOKING FOR - 3+ years building brand narrative and voice from scratch for consumer or prosumer products — not executing existing brand guidelines. - Proven ability to write sharp, concise copy and turn a rough product thesis into a narrative that lands with a specific audience. - Demonstrated track record running lightweight brand validation experiments without a fully scripted playbook. - Experience making independent platform and channel sequencing decisions based on brand fit and audience analysis. - Comfort owning ambiguous brand strategy questions and executing with autonomy at an early-stage company. - Clear, defensible point of view on what great brand work looks like in the AI and consumer space. - Background in brand strategy, positioning consultancy, or 0→1 brand work at early-stage startups — experience with consumer AI or productivity apps (e.g. PKM, second brain, or ambient AI tools) is a strong plus. - An existing personal following on X/Twitter or LinkedIn in the AI/productivity space is a plus. - Bilingual fluency in English and Mandarin is a plus. - No visa sponsorship available. LOCATION Hybrid — 3 days per week in office in the San Francisco Bay Area, California.
