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.

What We're Looking For
  • 2+ years of professional software engineering experience, comfortable operating independently on unfamiliar codebases.

  • A track record of owning and shipping mid-sized features or projects end to end.

  • Experience with building distributed data systems, feedback loops and measuring impact of work with metrics.

  • Strong testing discipline and experience improving CI/CD or developer tooling.

  • Someone who is focused on solving problems rather than working on particular tech stack / languages

  • Clear written and verbal communicator.

  • Bonus: experience with LLM/agentic tooling, AI cost observability, or internal developer platforms.

  • A generalist with an attitude for learning and growth.
