Title: Software Engineer II, AI Enablement Team Location: London 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. Diversity & Equal Opportunities: We embrace diversity and equality in a serious way. We are committed to building a team with a variety of backgrounds, skills, and views. The more inclusive we are, the better our work will be. Creating a culture of equality isn't just the right thing to do; it's also the smart thing.
