The RoleWe are looking for a Principal Software Developer to join our Manufacturing and Supply Chain (MSC) Engineering organization. You will provide technical leadership for complex, cross-cutting capabilities that support planning, scheduling, optimization, production, and supply chain workflows. Working across Agile teams, you will shape solution design, guide implementation and modernization, manage significant technical risks and dependencies, and raise engineering capability while remaining engaged in hands-on software delivery.
Your Impact
Provide technical leadership for complex or cross-team capabilities across the MSC product suite, from problem definition through delivery and support.
Partner with Product Management, Product Owners, Agile Team Leads, and System Architecture to evaluate feasibility, shape solution options, and define incremental delivery plans.
Lead architecture and design decisions within the scope of assigned initiatives, aligning implementation with product strategy and system architecture.
Develop and review critical software components, prototypes, interfaces, and technical designs, while supporting maintenance and modernization of existing codebases.
Drive engineering excellence in code quality, automated testing, CI/CD, observability, performance, reliability, scalability, and secure design.
Identify and manage cross-team technical dependencies, risks, trade-offs, and nonfunctional requirements in support of PI objectives.
Participate in SAFe events and provide technical leadership during PI Planning, backlog refinement, system demos, and Inspect and Adapt.
Mentor senior engineers and feature leads, establish reusable patterns, and promote knowledge transfer across product areas to reduce technical silos.
What You'll Need
