We’re building AI-native operations for marketing teams - automating the work that slows them down, from campaign briefs and performance reporting to creative review, compliance workflows, and paid media analysis. Our platform is purpose-built for marketing, trained on real marketing workflows and deeply integrated with ad platforms, CRMs, brand assets, and analytics tools.
What you’ll work on
- Develop and deploy ML/LLM systems for marketing-specific workflows (reporting, analysis, review, compliance)
- Build agentic systems with persistent memory, tool use, and workflow orchestration
- Integrate models with live data sources (Google Ads, GA4, Meta Ads, CRM, analytics)
- Improve retrieval, evaluation, and fine-tuning on marketing-domain data
- Collaborate closely with product and engineering to ship reliable, user-facing AI
What we’re looking for
- Strong experience building and shipping ML systems in production
- Hands-on experience with LLMs, RAG, agents, or workflow-driven AI systems
- Solid engineering fundamentals (Python, APIs, data pipelines, evaluation)
- Comfort working in a fast-moving product environment
- Bonus: experience with marketing, ads platforms, or analytics data. Also ideal if you’ve worked with Elixir.
