[Hiring] AI Workflow Engineer @Serotonin

Role Description

We are building the AI layer across Serotonin's marketing operations. This role sits at the intersection of systems thinking, AI tooling, and marketing execution. You will move across our marketing teams spanning PR, content, growth, social, and design, not to go deep on one team's problems, but to find the friction points that show up everywhere and build things multiple teams can pull from.

Your job is to understand how those teams work before you ever open a tool. That means asking the right questions, shadowing stakeholders, mapping actual workflows, and identifying where things slow down. The best outcome is never a custom fix for one person. It's something three teams are running independently six months from now.

This role is best suited for someone who listens to a team for 30 minutes, draws a process diagram, identifies the friction point, and ships a working solution within a week. You will work directly with marketing leads and internal and external client teams, translating real workflow problems into outcomes that scale across the organization.

Responsibilities

• Diagnose Bottlenecks
  • Spend real time with our different core marketing teams before touching any tooling.
  • Interview team members, map how work actually moves, and identify where things slow down or break.
• Design & Build for Multiple Teams
  • Build the workflow systems to solve them.
  • AI-powered workflows, content and campaign pipelines, and no-code automations that connect into the tools teams already use: HubSpot, Notion, Slack, various native social platforms.
• Workforce Adoption
  • You will own the operational backbone that makes AI adoption stick across a 90-person global team: prompt libraries, SOPs, workflow playbooks.
  • You will be responsible for leveling up the AI proficiency across the team.
• Maintain & Scale
  • Work directly with internal & external client teams to diagnose GTM bottlenecks and build AI-assisted solutions, from content at scale to campaign automation to research synthesis.
• Upleveling
  • Evaluate, test, and onboard tools as the landscape shifts.
  • Define how we measure impact: time saved, output quality, client adoption, etc., and build reports around what is working and what isn't.

Qualifications

• Strong problem-solving approach.
• Ability to interview the full team before proposing a solution.
• Capable of mapping a workflow end to end after a few conversations.
• Focus on making others' work easier rather than showcasing personal achievements.
• Think in systems that serve multiple stakeholders simultaneously.
• Strong prompt engineering across major LLMs.
• Hands-on experience with workflow automation tools like Make, Zapier, or n8n in a real production context.
• Comfort with APIs and JSON for connecting tools without native integration.
• Familiarity with the broader martech stack and AI creative tools is a plus.
• Understanding of how a marketing team operates at a foundational level.
• Knowledge of the difference between a campaign brief and a distribution workflow.
• Crypto or crypto marketing experience is a plus, but not required.

Benefits

• Competitive Salary
• Health Insurance (US Only)
• 401(k) (US Only)
• Remote Work Environment
• Parental Leave
• $80,000 - $190,000 a year
