MOO - Principal Engineer

• Domain leadership and technical strategy: Work with other engineering leaders to define the architectural roadmap across the whole order journey, spanning storefront, design and customisation tooling, checkout and payments, order orchestration, manufacturing (IMFG, our manufacturing execution system, and our Tulip shop-floor apps), fulfilment, shipping and Customer Service tooling. • Scale and reliability: Lead cross-team initiatives that increase throughput and reduce cost-to-serve. Get us through peak trading without heroics, from traffic spikes at the front of the funnel through to production release at the back, and make sure we know in advance what would break first. Improve observability and operability across the flow from "buy" to "delivered", reducing "where is my order" contacts and manual interventions. • AI-assisted development: Set the standard for how engineers across your estate use AI tooling day to day. Work with Security, Legal and Platform to define guardrails on review, testing and security, decide where these tools genuinely help and where they do not, and raise the practice of the teams around you rather than only your own. • Data and tooling coherence: Assist in enabling a 360-degree order view and actioning capabilities for Customer Service and Operations by standardising data pipelines and surfacing the right aggregates in [our developer portal / Backstage] and related tools. • Governance, facilitation and mentorship: Mentor Staff and Senior Engineers across all of the engineering department. Facilitate design reviews, hackathons and workshops, resolve technical conflicts, and align stakeholders on pragmatic, high-impact solutions. • Ecommerce performance and reliability: storefront and checkout stay fast and available through peak, and teams can change conversion-critical paths without fear. • Reliability and flow: uptime and lead-time accuracy across the whole order journey, from checkout availability through to delivery. • Peak readiness: we trade without heroics throughout the year, and we know in advance what would break first. • 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 architecture and data model across the order journey that accelerates migration while stabilising today's operations. • Faster delivery through AI-assisted development, with no loss in the quality of what we ship. • What’s it like to work at MOO? • MOO’s the kind of workplace where you can really be yourself. Dye your hair purple. Hit the sofa with your laptop. Whatever helps you feel comfortable and happy at work. We want to help you grow in your career and set you up for success – while also recognising the importance of a healthy work/life balance. • That’s why we offer 25 days holiday rising by one day for each year here (for 5 years), a matched pension scheme, and paid parental leave. We’ll offer you private healthcare, life insurance, a season ticket loan, and a cycle to work scheme. We also offer flexible work schedules with hybrid and remote working for certain roles as well as a Work From Anywhere program. • Diversity Statement • We are working hard to create a representative, inclusive and super-friendly team, because we know that different experiences, perspectives and backgrounds make for a better workplace. And that creates a better experience for our customers.
