Requirements

2–3+ years of hands-on experience owning or co-owning a corporate website or web growth program for a SaaS, AI, or tech company.
Demonstrated experience working directly with engineering teams — you know how to scope, prioritize, and collaborate in a technical environment.
Strong experimentation mindset: you've run A/B tests and conversion optimization programs on corporate or product marketing sites.
Data-driven by nature — you make decisions from evidence, not intuition alone. Experience with Amplitude or a comparable analytics platform is a strong plus.
Experience with a headless CMS (Sanity experience a bonus; Contentful, Prismic, or similar all count).
Excellent cross-functional communicator who can align stakeholders across Sales, Product, Engineering, and Marketing.

Nice To Haves

Background in a growth-stage startup or scaling SaaS/AI company — you're comfortable with ambiguity and know how to build systems where none exist.
Familiarity with AI products or AI-native workflows — bonus if you've worked at an AI company or integrated AI tooling into your marketing operations.
Experience with Amplitude Analytics or Statsig (experimentation layer).
Prior exposure to PLG (product-led growth) motions alongside enterprise pipeline generation.
