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 Supply Planner to own and execute the Master Production Schedule (MPS) for an assigned propulsion segment. This is the role that turns an agreed demand plan into an executable build plan, and then holds it together when reality moves.

As a Supply Planner, you work the executional horizon. You take the demand plan agreed in the SIOP cycle, 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 operate inside an established SIOP cadence, with defined demand and supply reviews, published planning parameters, and a monthly calendar the business plans to.

• 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.

• Actively participate in the SIOP process, contributing end-to-end visibility for segment inventory, capacity outlook, and the risk scenarios that affect program delivery.

• Partner with Materials Control, who own bill of material and item master integrity, and with Procurement on long-lead and constrained material so purchasing signal comes from the plan.

• Continuously improve planning practices to reduce inventory imbalance and obsolescence risk while protecting schedule attainment.

• Build the initial supply plan and planning parameters for new hardware as it moves from development into production.

• Master Production Schedule adherence for the assigned segment, measured monthly against committed program need dates.

• Manufacturing Orders released complete and on time to need date, with expedites driven by genuine demand change rather than planning error.

• Planning parameters reviewed on cycle, with published lead times validated against actual performance.

• Inventory positioned to protect the schedule while meeting turns and days-of-supply targets for the segment.

• Supply review inputs delivered complete and on time
