Job description

Design and build AI agents and automations that do real marketing, sales and analytics work for our clients, connected to their CRM, analytics and content tools, with people approving what matters.

• Location Remote, United States (Atlanta area a plus)
• Type Contract to start, with full-time possible
• Build agents with the Claude, OpenAI and Gemini APIs: tool use, retrieval, structured outputs and multi-step workflows
• Connect agents to HubSpot, Salesforce, GA4, BigQuery, Slack and CMS platforms through APIs, webhooks, n8n or Make
• Write test sets and evaluations, and re-run them after every prompt or model change
• Build guardrails: least-privilege access, human approval steps, action logs and an off switch
• Package reusable agents as Claude Skills and templates for our catalog
• Explain trade-offs in cost, speed and accuracy to non-technical clients

What you bring

• Experience with REST APIs, OAuth, webhooks and serverless functions
• A habit of writing tests and documentation someone else can follow
• Clear written communication with clients and teammates

How you use AI

• Shipped at least one LLM-powered feature, agent or automation that real people use, and can show how you measured it
• Hands-on with prompt design, tool/function calling and evaluation, not just chat interfaces
• Use AI coding assistants daily, and review and test everything they produce
• Can explain when an agent is the wrong answer and a simple automation is better

Nice to have

• Vector databases and retrieval
• Marketing or sales operations experience
• Experience with Claude Code or similar agentic coding tools
