AI Infra Engineer

About the role

We're building an intelligence layer at Serotonin, and we need someone to own it end to end. This role sits at the intersection of competitive intelligence, data engineering, and agentic AI. You'll pull signals from social platforms, on-chain activity, and paid media, and turn them into structured intelligence that shapes how we run accounts and campaigns, both internally and for clients. This is a systems role, not a workflow automation role. You'll design and maintain the data pipelines, agentic workflows, and full-stack applications that make our intelligence capabilities real and repeatable. The best outcome isn't a one-off solution for one team, rather it looks like a system three teams depend on independently six months from now. You'll work directly with marketing leads and client teams, understand how they actually operate before you build anything, and ship things that are live, used, and measurable.

Requirements

• Software Engineering (non-negotiable)
• Python, fluently: pipelines, agent systems, data processing, scripting
• Active GitHub with meaningful commit history, not forks and tutorials
• REST and GraphQL API experience building integrations, not configuring connectors
• SQL: schema design, not just pulling rows
• Full-stack development: Next.js or equivalent; you've shipped something users interact with in production
• LLM API usage: building directly with Anthropic or OpenAI APIs, including agent orchestration frameworks (LangGraph, CrewAI, or custom)
• Vector databases and RAG: embeddings, retrieval pipelines, semantic search
• Intelligence and Signal Layer
• Experience ingesting and fusing data from multiple external sources: social APIs (X, LinkedIn), ads APIs (Meta, Google), or similar multi-source environments
• Ability to translate raw signal into structured, actionable output for non-technical stakeholders
• Experience building dashboards or reporting layers others depend on operationally, not just internal notebooks
• No-code tools (Make, n8n, Zapier) are part of your toolkit but they don't act as the foundation of your practice. You reach for them when they're genuinely the fastest path to a reliable outcome. A strong developer who knows when to use no-code will always outperform a no-code specialist who can't own the harder technical work.
• On-Chain Data (strong plus)
• Dune Analytics or equivalent SQL querying against on-chain data
