Principal Engineer

MOO's engineering teams span the physical and digital worlds. Every order we take is manufactured after it is paid for, so the journey from "buy" to "delivered" runs through a factory as well as a database. That is true of the storefront, our design and customisation tools, cart, checkout and payments, business accounts, and equally true of order orchestration, manufacturing, fulfilment, shipping and the tooling our Customer Service and Operations teams use. The problems worth solving here run the length of that journey, and the hardest ones are usually the ones that cross it.

As we scale, we're bringing together two ecommerce platforms while also experimenting with our customers' browsing experiences to support growth. On the other side of the order, we're consolidating tooling for Customer Service and Operations, improving data visibility across the order journey, integrating new carriers, and increasing manufacturing capacity while protecting customer experience and margin. We're also changing how we build, with AI-assisted development now part of everyday engineering practice here.

You'll partner closely with engineering teams across our entire ecosystem, product leadership, and our Platform group, to deliver a coherent, scalable architecture and unblock cross-team delivery.

Bring deep technical leadership across MOO's ecommerce ecosystem, from storefront and checkout through to delivered. You'll support in setting the architectural direction for that journey and enable multiple teams to move quickly and efficiently.

Balance essential scaling of today's systems with an iterative migration away from legacy components. Define contracts, events and guardrails that make our ecosystem observable, resilient and cost-efficient. Set the standard for how we use AI-assisted development, so we get the speed without lowering the quality bar. Translate operational requirements from Operations and Customer Service, and commercial requirements from Product and Trading, into pragmatic platform improvements.
You'll work with our engineering team, who are largely based in the UK, and with stakeholders at our manufacturing facilities in East Providence, Rhode Island and Dagenham, London.

Senior IC role reporting into senior leadership (VP of Technology). Scope spans multiple teams across ecommerce and post-purchase, partnering closely with Product leadership and Platform and Architecture peers to help drive what the future of MOOs systems look like.
