AI Ads Product Builder/FDE

Gigi builds AI-powered products for enterprise media buying, including an AI media manager for Amazon DSP. The AI Ads Product Builder/FDE combines advertising expertise, software engineering, and client service to build and deploy AI-powered products, workflows, and integrations with customers.

Responsibilities:

• Work directly with agency leaders and ads managers. Understand their business priorities, campaign workflows, reporting needs, and operational challenges. Use your advertising knowledge to ask useful questions, explain possibilities and tradeoffs in plain language, and turn ambiguous needs into a clear problem and a practical solution
• Ship end to end. You'll own features from the data layer through the agent logic to the interface a media buyer actually touches. Our stack includes Python, FastAPI, LangGraph and LangChain; TypeScript, Vue and Nuxt; Java and Spring Boot; PostgreSQL, pgvector, Redis and NATS; and AWS
• Build with AI as a core part of your development workflow. Use Codex, Claude Code, Cursor, and other coding agents to help plan, implement, test, debug, and review software. You are still responsible for the architecture, quality, and correctness of what gets shipped
• Connect Gigi to advertising workflows. Build integrations with the advertising tools, APIs, and data sources customers rely on. Handle permissions, data mapping, failures, and the operational details needed to make a solution work reliably across Gigi and connected systems
• Build solutions that strengthen the product. Work with Product and Engineering to decide what should become a shared feature, a reusable integration, or an agency-specific configuration. Solve the immediate customer problem while making future implementations easier
• Build reliable agentic systems. You'll learn to design tools, retrieval, memory, evaluations, guardrails, and human approval flows that make Gigi dependable enough to take action inside real advertising accounts. Prior experience with all of these is not expected
• Deliver a strong client experience. Own discovery, prototyping, implementation, and rollout in collaboration with customers and the team. Set clear expectations, communicate progress and setbacks, help clients adopt what you build, and follow through when something isn't working. Use feedback and actual workflow results to improve the solution
• Work with clients in person. Travel to client locations as needed for discovery, working sessions, onboarding, and rollout support. Build relationships with both agency leaders and the people using Gigi every day
