About Swap

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 centralises 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.

Responsibilities

• Build cost observability and usage-tracking tooling across LLM and agent workloads, so teams can see what AI actually costs and where we can accelerate productivity and impact.
• Design and ship internal tooling and guardrails that let business and engineering teams adopt agentic coding workflows safely and productively.
• Evaluate new AI tools, models, and vendors, and turn findings into clear build-vs-buy recommendations.
• Write and maintain production quality code and automated tests for the platforms and tools you own.
• Review peers' code for correctness, readability, and maintainability.
• Own delivery of projects end to end, from scoping through production rollout across a mix of infrastructure, tooling, and process work.
• Establish and socialise best practices for AI usage across the business.
