AI GTM Engineer

Join Papaya's Marketing team as an AI GTM Engineer. In this foundational role, you will design, build, and govern the AI agent infrastructure that powers our marketing engine. You will work at the intersection of engineering, marketing operations, and AI product thinking, reporting directly to the Marketing Ops Lead. Your responsibilities will include designing and building the full AI agent stack, owning the technical architecture, maintaining the prompt library, defining guardrails, monitoring agent performance, and training the marketing team on AI tools and workflows.

• Design and build the full AI agent stack for the marketing organization, including personal agents, shared service agents, and orchestration agents.
• Own the technical architecture end-to-end, including trigger design, LLM selection, data integrations, output formatting, and approval routing.
• Build and maintain the prompt library, golden datasets, and QA framework, running structured testing before every agent goes live.
• Solid understanding of B2B SaaS marketing — demand gen, ABX, SDR outreach, and content workflows
• Coding knowledge in Python or JavaScript — vibe coding with AI assistance is absolutely fine; deep software engineering experience is not required
• Solid understanding of REST APIs and webhooks — you have built and debugged multi-system integrations
• Hands-on experience with at least one LLM API (Anthropic Claude or OpenAI) building real automated workflows, not just demos
• Strong communication skills — you translate technical constraints into plain language for non-technical teams daily
• Experience designing and evaluating prompts to hit measurable quality targets
• Proven experience with workflow automation tools such as n8n, Zapier, or Make — building multi-step workflows connected to real business systems
• Familiarity with CRM and marketing automation data models (Salesforce, HubSpot)
