Supply Planner

About the Company

General Matter enriches uranium.

We are designing, building, and operating the world’s lowest-cost enrichment services, here in the US.  

In the process, we are restoring America’s ability to produce nuclear fuel to power AI, advanced manufacturing and critical industries our country relies on to remain competitive. 

Fuel drives the cost of advanced reactor electricity production, and enrichment drives the cost of the fuel that advanced reactors consume.  Reliable, low-cost enrichment is the catalyst for the nuclear Renaissance now under way.

Our mission is to make nuclear not only the cleanest and safest source of baseload power, but also the most affordable.  We believe abundant nuclear energy will lead to a post-scarcity society. 

We were incubated inside Founders Fund, like Anduril and Palantir before us, and are backed by over a dozen of the world's top venture capital firms.  

Our lean, world-class team of engineers and operators is applying a first-principles approach to solving the problem of nuclear fuel production.  

We are a mission-driven company with a culture of urgency, accountability, and transparency. 

Help us build a high-energy society by making the cleanest, safest form of baseload energy the most affordable. 

About This Role 

Every program runs on parts arriving when they are scheduled. As Supply Planner, you turn shifting demand into a plan we can trust: what we need, when we need it, and what to order today to get there. You will build the planning processes from the ground up, run them yourself, and work hand in hand with sourcing to place orders and close gaps with suppliers. If you want to be the person the whole team relies on to know what is coming next, this is the seat.

Responsibilities

• Set the planning playbook. Put supply and material planning best practices in place, from planning cadence and system parameters to data rules, then run them week after week.
• Know where every part stands. Build line of balance views that show what is on hand, on order, and still needed against demand, so gaps show up early, and escalate long-lead or single-source exposure to the Global Supply Manager.
• Turn plan changes into purchase actions. When demand or schedules move, re-plan quickly and convert the change into purchase requisitions, pull-ins, or pushouts.
• Carry orders through to delivery. Issue and manage purchase orders, request quotes, confirm dates and quantities with suppliers, expedite late parts, and resolve receiving and invoice discrepancies alongside the rest of the supply chain team.
• Keep stock right-sized. Set safety stock and reorder points and manage stocked SKUs, so common items are on the shelf without tying up cash.
• Be the planner’s voice in our systems. Support the ERP/MES implementation and make sure the data, parameters, and workflows fit how we operate.
• Forecast the spend. Project hardware spend from the build plan and stand up the S&OP process that ties supply, finance, and production to one plan.

Basic Qualifications

• Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc). 
• Strong understanding of engineering fundamentals.
• Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information.
• Bachelor’s degree in engineering, business, supply chain, or a related technical field.

• 5+ years in supply planning, material planning, or procurement for a manufacturing or hardware program.
• Hands-on experience running MRP in an ERP system, with strong spreadsheet and data analysis skills.
• Hands-on procurement experience: creating purchase orders, working with suppliers on quotes, lead times, and delivery dates, and expediting to get material delivered.
• Exacting with data, persistent with suppliers, and calm when the schedule changes underneath you.
• Ability to obtain and maintain any required security clearance and access authorization. 

Preferred Skills and Experience

• Experience in a fast-paced engineering or highly technical environment, with a resourceful approach to delivering under tight timelines or budget constraints.
• Built an MRP and S&OP process from the ground up, not just operated one.
• Worked across supply, material, and demand planning, and understand how a change in one reshapes the others.
• Helped implement or migrate an ERP or MES system.
• Experience building digital tools for supply visibility, such as planning dashboards or shortage reports, and a habit of using AI in your daily work.
• Start-up or early-stage company experience.

Additional Requirements

• Ability to work extended hours and weekends as necessary.
