Supply Planner

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.

About the role

As a Supply Planner, you own and execute the Master Production Schedule (MPS) for an assigned propulsion segment. This role turns an agreed demand plan into an executable build plan and maintains it when reality shifts. You take the demand plan from the SIOP cycle, convert it into a time-phased, capacity-feasible supply plan, and release Manufacturing Orders to put hardware in motion. You own the plan and its execution: what gets built, in what quantity, in what sequence, and by when. Bills of material integrity is managed by Materials Control, and you collaborate with that team when structural or engineering changes impact releases.

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 reschedule, cancel, and expedite messages to prevent shortages on the production floor.
• Maintain and improve planning parameters (lead times, order policies, lot sizing, 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, avoiding repeat expedites.
• Balance load against constraint resources with Production Control and escalate material or capacity constraints into the SIOP cycle with recommended recovery options.
• Actively participate in the SIOP process, contributing visibility for segment inventory, capacity outlook, and risk scenarios affecting program delivery.
• Partner with Materials Control (BOM/item master integrity) and Procurement on long-lead and constrained material to ensure purchasing signals align with 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 transitioning from development to production.

Role Goals and Measures

• 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 changes rather than planning errors.
• 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 to every monthly SIOP cycle.

Requirements

• Bachelor’s degree in Supply Chain, Business, Engineering, Analytics, Finance, or a related field, or equivalent combination of education and experience.
• Minimum of three years of experience in supply planning, production planning, master scheduling, or production control within a manufacturing environment.
• ERP experience (SAP, Oracle, Odoo, Katana, Sage, etc.) and advanced Excel skills.
• Working command of MRP logic, including how bills of material, lead times, order policies, and planning parameters drive the plan.
• Ability to work with both quantitative and qualitative data to build a defensible plan, not just maintain a statistical model.
• Strong analytical skills to collect, organize, analyze, and disseminate significant amounts of information with attention to detail.
• Experience aggregating data from cross-functional stakeholders to support high-level, strategic decision-making.
• Action-oriented and results-driven, with the ability to work under pressure, prioritize workload, and meet tight deadlines.
• Excellent critical thinking and agility to learn and adapt as the business scales.
• Disciplined approach to planning data integrity, with judgment to identify untrustworthy plan inputs.
• Ability to identify process and data gaps and provide recommendations for improvement.
• Clear and concise communication tailored to the audience, including holding firm with Program Management, Engineering, and Manufacturing when the plan is uncomfortable.

Skills

• SIOP process, cadence, and governance.
• Master Production Scheduling and material requirements planning principles.
• Demand planning and forecasting methodologies, including forecast accuracy and bias measurement.
• Demand and supply balancing across planning horizons.
• Inventory management strategies, including safety stock and slow-moving/obsolete material.
• Scenario modeling and trade-off analysis.
• Supply chain KPIs: schedule attainment, on-time delivery, inventory turns, and capacity utilization.
• KPI and dashboard development.
• Manufacturing operations and fulfillment constraints in a low-volume, high-complexity environment.

Preferred Experience

• APICS CPIM, CSCP, or IBF CPF certification.
• Aerospace, defense, or another low-volume, high-complexity, engineer-to-order environment where backlog, funding milestones, and contract dates drive planning.
• Experience operating within an established SIOP or S&OP cadence and contributing to its continuous improvement.
• Facilitating demand or supply reviews within an established SIOP or S&OP cadence.
• Demonstrated improvement in forecast accuracy across an assigned portfolio.
• Exposure to PLM (Windchill) and engineering change management.
• Experience with data visualization tools.

Schedule

• Hybrid schedule with a minimum of three days per week on-site in Berthoud, CO.
• Works in both office and manufacturing environments with regular presence on the production floor.
• Able to lift and transport parts and tools weighing up to 25 lbs.

Pay

Base compensation range: $66,000 - $82,000, determined by education, experience, knowledge, skills, and abilities.
