Principal Engineer (Post-Purchase) at moo

MOO set out to shake up the world of print back in 2006. And we’ve come a long way since. Today we’re a 400 + strong team (we’re thinking of getting matching jackets) who create print and digital products for companies of all sizes – from Google and AirBnB to the guy who makes those amazing prints you found at a craft fair.    Our global HQ is in London, UK, while we also have premises in Dagenham. In the US, you’ll find us in Boston, MA, as well as East Providence, RI and Denver, CO.   We’re making new and exciting things – and we could really do with your help.  We’re making new and exciting things – and we could really do with your help.   MOO’s Post‑purchase domain spans the physical and digital worlds: order orchestration, manufacturing, fulfilment, shipping and customer support tooling. As we scale, we’re consolidating tooling for CS and Ops, improving data visibility across the order journey, integrating new carriers, and increasing throughput in manufacturing while protecting customer experience and margin. You’ll partner closely with Nexus and Forge teams to deliver a coherent, scalable architecture and unblock cross‑team delivery.   We are looking for someone who is able to work 2-3 days a week out of our East Providence office, with potential occasional travel to London to work with our engineering team who are largely based in the UK.    *Please Note* Relocation assistance available for the right candidate   The Role • Bring deep technical leadership to the Post‑purchase area, owning the end‑to‑end architectural direction and enabling 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, and translate operational requirements from Ops and CS into pragmatic platform improvements. • Work with our engineering team who are based in the UK, while supporting our stakeholders on-site at our manufacturing facility and office in East Providence, Rhode Island. Responsibilities • Domain leadership and technical strategy: Work with other leaders in Post-purchase to define the architectural roadmap across manufacturing (IMFG, Tulip apps), fulfilment, shipping and CS tooling. • Scale, reliability and delivery: Lead cross‑team initiatives that increase throughput and reduce cost‑to‑serve. Improve observability and operability across the flow from “buy” to “delivered,” reducing WISMO and manual interventions. • Data and tooling coherence: Assist in enabling a 360° order view and actioning capabilities for CS and Ops by standardising data pipelines and surfacing the right aggregates in Backstage and related tools. • Governance, facilitation and mentorship: Mentor Staff and Senior Engineers across Nexus and Forge, facilitate design reviews and workshops, resolve technical conflicts, and align stakeholders on pragmatic, high‑impact solutions. About You • Proven track record shaping architecture and delivery for complex post-purchase/manufacturing or adjacent domains at scale: order orchestration, manufacturing/fulfilment, shipping, returns, and CS tooling. • Expert at designing service and event contracts, data flows and reliability patterns that enable multiple teams to ship safely and quickly. • Skilled facilitator who can align Ops, CS, Product and Engineering, resolve technical disagreement, and translate architecture into measurable business impact. Comfortable working with remote teams across different time zones. • Comfortable balancing migration with tactical scaling work in live systems. Nice To Haves • Experience with manufacturing execution systems, batching and scheduling algorithms, and warehouse/dispatch integrations. • Prior work migrating e-commerce platforms and improving CS agent experience through unified data and actioning. Outcomes You Will Drive • Reliability and flow: uptime and lead‑time accuracy across post‑purchase stages. • Faster and cheaper dispatch through automated carrier integrations and improved lead‑time logic. • Higher manufacturing throughput via robust batching, scheduling and performance improvements in IMFG and Tulip apps. • Coherent post‑purchase architecture and data model that accelerates migration while stabilising today’s operations.
