Swap is the infrastructure behind modern agentic commerce. The only AI-native platform connecting backend operations with a forward-thinking storefront experience.
Built for brands that want to sell anything - anywhere, Swap centralizes global operations, powers intelligent workflows, and unlocks margin-protecting decisions with real-time data and capability. Our products span cross-border, tax, returns, demand planning, and our next-generation agentic storefront, giving merchants full transparency and the ability to act with confidence.
At Swap, we’re building a culture that values clarity, creativity, and shared ownership as we redefine how global commerce works.
About the Role
We’re not hiring a traditional data scientist.
We’re looking for:
Half human intuition.
Half machine leverage.
Running parallel code paths.
Deploying agents to explore solution spaces while you sleep.
Swap is building a fully agentic, end-to-end AI Storefront, from search and personalization to outfit creation, virtual try-on, checkout, payments, returns, shipping, refunds, and support.
You’ll join our Agentic squad, working alongside five AI and data science professionals to refine, scale, and evolve the intelligence layer behind our agentic storefront. This is a senior-level, high-agency generalist role for someone who can move fluidly across models, agents, experimentation, and product decisions — and ship fast in a startup environment.
Responsibilities
Collaborate closely with Product, Engineering, and the Agentic team to optimize AI-driven features across the full commerce journey
Design and improve recommendation and personalisation systems using behavioral and transactional data
Enhance conversational agents, multi-agent flows, and tool integrations
Iterate on virtual try-on and vision systems through prompt engineering, fine-tuning, and model chaining
Rapidly prototype new AI capabilities and evolve them into production-grade systems
Build and refine experimentation frameworks (A/B testing, evaluation pipelines, benchmarking)
Improve conversion, retention, and operational efficiency through applied ML
Identify automation opportunities and design agent-powered internal tooling
Contribute to shaping the evolving intelligence architecture of our agentic commerce platform
