AI & GTM Engineer

New York / Copenhagen / San Francisco / Chicago Full Time

Who is Serotonin
Serotonin is the top go-to-market firm for transformative technologies, specializing in marketing, strategy, recruiting, and legal services. With a global team of 90 across 15 countries, Serotonin has supported over 300 clients in consumer tech, web3 infrastructure, digital assets, venture capital, and AI since its launch in 2020. Delivering end-to-end go-to-market solutions across all major marketing channels - including public relations, growth marketing, on-chain analytics, content, research, social, and design - Serotonin accelerates global innovation. At the core of our business is the Serotonin Platform, serving as a central nucleus for the web3 ecosystem, connecting builders and founders with essential resources to drive business growth.

About the Role
We’re building the AI layer across Serotonin’s marketing operations. This role sits at the intersection of AI tooling, GTM strategy, and marketing execution. You will identify where AI can compress timelines, improve output quality, and unlock competitive advantage for our internal teams and clients - and then actually build those systems.
This isn’t a role for someone who wants to talk about AI. It’s for someone who ships AI-powered workflows regularly and iterates based on the next best thing out there. You’ll work directly with marketing leads, account teams, and clients across web3, consumer tech, and AI - translating cutting-edge AI capabilities into practical GTM impact.
