AI Engineer / Automation Specialist

We're a boutique digital marketing agency that has built and launched an AI-powered paid media management platform for our clients. The foundation is solid - autonomous AI agents analyse campaign data, flag anomalies, recommend budget shifts, and generate creative briefs across Meta and Google Ads, with a real-time client portal pulling everything into one dashboard. We need someone sharp to help us finish the last 20%, harden it, and scale it from a handful of clients to many. The Stack Backend/Database: Convex (serverless functions, real-time DB) Frontend/Hosting: Vercel + Vite (React) AI/LLM: Anthropic Claude (via API) powering autonomous agent workflows Integrations: Meta Ads API, Google Ads API, Shopify, GA4, Klaviyo Agent scripts: Python, scheduled via cron, reading/writing to the database Email: Resend What We Need Workflow architecture: Design and improve multi-agent workflows - agents that analyse, decide, and act across ad platforms without manual intervention. API security & compliance: You understand how to connect AI systems to Meta and Google Ads APIs safely - rate limits, token management, approval flows, and guardrails that prevent account suspensions. Refinement & hardening: The MVP works. We need better error handling, edge case coverage, onboarding automation for new clients, and reliability at scale. Scaling: Make the system multi-tenant-ready so onboarding a new client is fast and repeatable. AI-native thinking: You don't just write code - you think about how to make AI do the heavy lifting. Prompt engineering, agentic patterns, structured outputs. You Are Experienced with LLM APIs (Claude, GPT, etc.) in production - not just prototyping. Strong in Python and comfortable with serverless architectures (Convex, Supabase, Firebase, or similar). Familiar with Meta Ads API and/or Google Ads API (or quick to learn with solid API experience). Security-conscious - you know why API tokens, rate limits, and audit trails matter. A fast, autonomous worker. We move quickly and need someone who can own tasks end-to-end. Based in a timezone that overlaps with AEST (Australia) for at least a few hours. Not Required But a Plus Experience with Convex specifically Experience with ad tech or marketing automation Familiarity with agentic AI frameworks (CrewAI, LangGraph, or custom agent loops) Engagement Start as a focused project (est. 4-6 weeks) with potential for ongoing work as the platform grows. You'll work directly with the founder. Short feedback loops, no bureaucracy. To Apply Tell me: A project where you connected an LLM to a live API (ads, payments, CRM, etc.) in production - what went wrong and how you fixed it. Your experience with multi-agent or agentic AI systems. Don't send a generic proposal. Feel free to use AI though, I would expect it!
