Marketing Lead

About the role

This is a hands-on, 0→1 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 competitive AI landscape — while feeding real audience signal back into what the company builds next.

Responsibilities

• 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 tailored to AI-native and power-user segments.
• Write, test, and iterate on marketing assets — copy, positioning, and brand identity — directly and independently.
• Test messaging angles across market segments and double down on what demonstrably resonates.
• Own platform and channel sequencing decisions, choosing where to establish a real presence and when.
• Act as an active stakeholder with Product and Engineering, translating audience insight into roadmap influence.
• Coordinate with the global branding and marketing team to keep US execution aligned as the brand evolves.

Requirements

• 3+ years building brand narrative and voice from scratch for consumer or prosumer products — not inheriting existing guidelines.
• Demonstrated experience running lightweight brand validation experiments (messaging tests, qualitative interviews, community signal) to surface and confirm early-adopter audiences.
• Strong writing skills with a track record of turning product theses into copy that lands with specific audiences.
• Experience making platform and sequencing decisions independently, based on brand fit and audience analysis.
• Comfort owning ambiguous brand strategy questions and executing without a fully scripted playbook.
• A clear, reasoned point of view on what good brand work looks like in the AI and consumer space.
• Experience collaborating with product and engineering teams as an upstream stakeholder influencing roadmap priorities.
• Background in brand or positioning work at consumer AI or productivity applications (e.g. note-taking, PKM, or ambient AI tools) is a strong plus.
• Familiarity with second brain, personal knowledge management (PKM), or ambient AI user personas is a plus.
• An existing personal following on X/Twitter or LinkedIn in the AI/productivity space is a plus.
• Bilingual proficiency in English and Mandarin is a plus.
