Our Team The Fulfillment Planning team sits at the heart of Cimpress’ manufacturing network. We build the optimization and planning software that decides where, when, and how millions of customized products get produced and shipped across a global network of manufacturing sites (plants). Our services are responsible for modeling plant capacity, labor, materials, and shipping options; they use mathematical optimization (e.g., linear/constraint solvers) to make complex trade-offs between cost, throughput, and on-time delivery. We work directly with plant operations, shipping, and product teams to turn real-world constraints into stable, explainable software systems used every day on the production floor. As a Lead Software Engineer on this squad, you’ll own major components and projects in our production planning, ganging (grouping items together for efficient printing), and shipping planning systems, improving how our systems make decisions and helping plants understand and trust those decisions. What You Will Do Lead delivery of complex features and services in our production planning, ganging, and shipping planning stack, from problem framing and design through implementation, rollout, and long-term maintenance. Design and evolve optimization-driven systems (e.g., capacity planning, scheduling, shipping plan generation) in our modern stack: C# / .NET, AWS, event-driven services, and data-intensive backends. Partner directly with non-technical stakeholders (plant operations, shipping, product, support) to clarify requirements, explain trade-offs, and influence prioritization based on customer outcomes (e.g., on-time shipment, labor efficiency, material usage). Own technical quality for the work you lead: drive testing strategies, reliability, security, observability, and performance for your services; participate in and lead code and design reviews. Shape the architecture of our planning platform by proposing and implementing improvements that keep the system reliable, maintainable, and adaptable as product lines and plants evolve. Drive incident response and problem investigation for your domain: use metrics, logs, and data analysis to get to root causes and turn incident learnings into improvements to code, configuration, and best practices. Mentor and unblock other engineers on the squad through pairing, thoughtful code reviews, and sharing context on our planning models, cost structures, and plant workflows. Your Qualifications At Cimpress, we are striving to hire individuals that add new ideas and perspectives to our teams and enhance our culture. No matter your background or work experience, we strongly encourage you to apply—even if you feel that you don’t meet the exact requirements or have the same qualifications. You might be a great candidate for this or other opportunities.
