About the role

Key responsibilities & impact

Audit existing marketing workflows across content, social, PR, growth, and design, and systematically redesign them with AI tooling to increase speed, quality, and scale
Build and maintain AI-powered content and campaign pipelines for internal teams and client accounts, reducing manual effort without sacrificing brand quality
Develop and own a firm-wide prompt library, AI SOPs, and workflow playbooks - the operational backbone that makes AI adoption stick across a 90-person global team
Identify, evaluate, and onboard new AI tools relevant to marketing and GTM; maintain and evolve the firm’s AI tooling stack as the landscape shifts
Partner with client teams to diagnose GTM bottlenecks and design AI-assisted solutions - from content at scale to campaign automation to research synthesis
Build no-code and low-code automations that connect AI tools into existing martech stacks (HubSpot, Notion, Slack, social platforms) using tools like Make, Zapier, or n8n
Train and upskill marketing teams across the firm on AI tools and workflows, raising the baseline AI fluency of every team you work with
Define and track the metrics that prove AI workflow impact - time saved, output volume, quality scores, and client adoption, and report findings to leadership

Requirements

What you’ll need

Expert-level prompt engineering across major LLMs (Claude, ChatGPT, Gemini, Perplexity) - you write system prompts, build multi-turn workflows, and iterate until the output is ready to ship externally
Hands-on experience with AI creative tools: image generation (Midjourney, Adobe Firefly), video (Runway, Sora, Kling), and audio (ElevenLabs) in a real marketing context
Workflow automation using no-code/low-code platforms (Make, Zapier, n8n) - you’ve connected APIs, built multi-step automations, and maintained them in production
Comfortable working with APIs, webhooks, and JSON - enough to connect AI tools even when there’s no native integration
Familiarity with AI-native martech: HubSpot AI, Jasper, Copy.ai, Notion AI, Sprout Social, and the broader martech stack these tools plug into
Experience building prompt templates, internal AI playbooks, and training materials that actually get used - not just written
Ability to use AI tools to synthesize research, competitive intelligence, and market data at speed, NotebookLM, Perplexity, and similar tools are already part of your workflow
Comfortable measuring the performance of AI-assisted campaigns and workflows: you know how to A/B test AI-generated content and interpret what the data is telling you
Ability to translate AI workflow data and campaign performance into clear strategic recommendations for clients and internal stakeholders
Familiarity with analytics tools (GA4, HubSpot analytics, basic SQL a plus), you’re not a data scientist, but you’re not afraid of a spreadsheet or a dashboard
Strong critical thinking around AI outputs - you know when to trust the model and when to override it, and you build that judgment into the workflows you create
Familiarity with the web3 GTM landscape: how protocols, DAOs, and crypto projects build audiences, launch products, and grow communities is not foreign to you
Working knowledge of how AI and blockchain intersect: AI agents, on-chain AI applications, decentralized compute, and what these mean for how clients go to market
Awareness of on-chain analytics tools (Dune, Nansen, Arkham, Flipside) and how data from these platforms can inform GTM strategy and content
Strong interest in the space is the baseline: prior experience in crypto or web3 marketing environments is a strong plus
Doesn’t care about rigid job titles: is equally comfortable acting as a strategist, a builder, a trainer, or an operator depending on what the problem demands
Loves tinkering and experimenting with new tools before anyone else has heard of them: and has the judgment to know which ones are worth deploying at scale
Gets energy from hard, ambiguous problems: not from following established playbooks, but from writing the new ones
Ships fast and isn’t precious about being wrong on the first try
Wants to see their work create real client impact: not just live in a deck or a Notion doc that nobody reads
Believes AI is a multiplier, not a shortcut: and builds workflows that reflect the difference
Thrives in a fast-moving, globally distributed team where autonomy is high and there’s no one to hand the problem off to
