Job description

Performance Marketing Manager, Paid Search & AI Advertising

The role asks for someone to run paid search across Google and Microsoft plus an early effort on ChatGPT advertising, from strategy and budgets down to building campaigns and landing pages. A strong candidate has several years of hands on paid search work, manages large budgets, and ties ad results to pipeline rather than clicks. Comfort with technical products and developer audiences matters, along with a habit of testing new channels without a ready playbook.

How it fits the AI era

AI shifts the work toward new ad surfaces such as ChatGPT and toward faster testing of copy and landing pages, while the judgment about where to spend and what counts as a qualified lead stays with the person. The role sits close to the company's own product, so the marketer is both a user of AI tools and a seller of them. Measurement and honest attribution remain human calls, especially on channels with less mature reporting.

How it builds AI experience

The job offers direct experience building an advertising approach on an AI platform while it is still forming, alongside established search channels. A candidate can build this by running small structured tests on new ad formats, learning how AI assisted search changes intent and query patterns, and connecting those results to CRM data. Familiarity with the company's agent and evaluation tools would help in speaking credibly to developer and enterprise audiences.

Worth showing

• Google Ads campaign building
• Microsoft Advertising experience
• Landing page A/B testing
