Senior AI Engineer - Marketing AI Transformation

You'll be a senior engineer on a deliberately flat, entrepreneurial team. Day to day you'll design and build agentic AI systems - agents, workflows, the orchestration layer that ties them together, and the infrastructure that makes all of it reliable at scale. This is hands-on building, not oversight.

What you'll do

• Design and build agentic workflows and the AI systems behind them - agents, the orchestration layer, and the infrastructure that runs them reliably
• Take significant, ambiguous areas of the system and drive them from rough idea to working capability
• Help scale the platform from a first working workflow to something used across the marketing organization
• Contribute to evaluation, quality, and reliability - making sure systems don't just run, but run well
• Work directly with the people who'll use what we build, and translate their needs into systems
• Substantial software engineering experience, with a track record of building and shipping complex systems
• Hands-on experience building agentic or LLM-based systems - this is a requirement, not a nice-to-have. We’re looking for someone who has designed agent workflows, wrestled with prompts and context, handled the failure modes, and shipped something real
• Strong product instincts: comfortable with ambiguity, able to define a problem before solving it, and opinionated about what's worth building
• Comfort working in a small, flat, fast-moving team where you set much of your own direction
• The ability to communicate clearly with non-technical partners across marketing

Nice to have

• Experience with orchestration frameworks for agentic systems (e.g. LangGraph or similar)
• Experience with evaluation frameworks, RAG, or working with knowledge bases at scale
• Familiarity with the marketing domain, or a genuine interest in it
• Experience taking a system from early prototype to broad organizational adoption

We're a small, fast-moving team building the AI systems that are changing how Wix's marketing organization works. Our goal is to take Wix marketing into the agentic era, where marketers are supported end-to-end by AI that carries real work from start to finish.

This is a rare chance to build agentic AI that's actually in production and actually changing how a large organization works. Not a demo and not a proof of concept. You'll have real ownership, work alongside experienced engineers on genuinely hard problems, and help define what an AI-native marketing organization looks like.
