Supply Planner

The future of aerospace and defense starts here. 

Ursa Major was founded to revolutionize how America and its allies access and apply high-performance propulsion, from hypersonics to solid rocket motors, satellite maneuvering and launch. We design and deliver propulsion and defense systems that solve the most urgent and critical national security demands. 

We are seeking a Senior Supply Planner to own and execute the Master Production Schedule (MPS) for an assigned propulsion segment and to lead the integration of demand forecasting into our supply and production plans. This is the role that turns an agreed demand plan into an executable build plan, and then holds it together when reality moves. You will operate with minimal supervision, handle complex planning issues, and provide leadership and mentoring within the planning function.

As a Senior Supply Planner, you work the executional horizon and influence the tactical horizon. You take the demand plan agreed in the SIOP cycle, along with sales and marketing inputs, convert it into a time-phased and capacity-feasible supply plan, and release the Manufacturing Orders that put hardware in motion. You own the plan and the orders it produces: what gets built, in what quantity, in what sequence, and by when. Bills of material and their system-of-record integrity are owned by Materials Control, and you work with that team when a structure or an engineering change would block a release. You also provide guidance and coaching to more junior planners and coordinators as needed.

You operate inside an established SIOP cadence, with defined demand and supply reviews, published planning parameters, and a monthly calendar the business plans to.

Responsibilities:

• Own adherence to and execution of the Master Production Schedule for an assigned segment, translating the agreed demand plan into a time-phased, capacity-feasible supply plan.
• Release, sequence, and maintain Manufacturing Orders (MO) in the ERP against program need dates, material availability, and available capacity.
• Run MRP for the assigned segment and work the reschedule, cancel, and expedite messages it produces before shortages reach the floor.
• Maintain and improve planning parameters for the segment, including lead times, order policies, lot sizing, and safety stock, while meeting program service targets.
• Develop and refine replenishment and safety stock strategies for assigned inventory locations, including disposition of slow-moving and obsolete material.
• Drive resolution of supply shortages through root cause analysis and collaboration with Materials Control, Procurement, and Manufacturing, rather than through repeat expedites.
• Balance load against constraint resources with Production Control and escalate material or capacity constraints into the SIOP cycle with a recommended recovery option.
