Lead Software Engineer, Fulfillment Planning - East Coast US Remote

Cimpress Technology is a company focused on mass customization, developing software that aids in the production and shipping of customized products. The Lead Software Engineer will be responsible for delivering complex features in production planning and shipping systems, collaborating with both technical and non-technical stakeholders to enhance decision-making processes within the manufacturing network.

Responsibilities:

• 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

Requirements:

• 7+ years of experience building and operating commercial software systems
• Strong experience with object-oriented backend development and web-based services, ideally with C# / .NET
• Experience with AWS or another major cloud provider (designing, deploying, and operating services in production)
• Solid experience with databases (SQL) and working with data at scale (e.g., analyzing logs/metrics, writing queries to investigate behavior)
• A track record of leading delivery of complex features or services: breaking down work, estimating, coordinating with stakeholders, and shipping iteratively
• Strong communication skills: you can talk through problems and solutions clearly with both engineers and non-technical stakeholders, and you're willing to say “no” or “not yet” when needed, with evidence
• Familiarity with engineering best practices: testing, code reviews, CI/CD, security basics, observability (logging, alerting, dashboards), and runbooks
• Experience with optimization, operations research, or scheduling (e.g., linear/integer/dynamic programming, constraint solvers, heuristics) or with other decision automation systems
• Background in manufacturing, logistics, or supply-chain systems
• Experience building systems that require fairness, prioritization, or trade-offs across many customers (e.g., routing, allocation, capacity management)
• Experience working in a remote-first, multi-time-zone team
