Dynamics Engineer

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 the Role As a Dynamics Engineer, you will own the dynamics, loads, and vibration analysis of General Matter hardware. You will own design requirements for vibe and shock design. You will work closely with cross-functional teams, including mechanical engineers, electrical engineers, software engineers, chemical engineers, manufacturing engineers, nuclear engineers, materials scientists and physicists.  Responsibilities Define requirements and own analysis and testing of dynamics through hand calcs and data analysis.  Use data to inform design and performance decisions. Support optimization of designs for cost, performance, and manufacturability. Execute dynamics testing from start to finish (pre-test planning, sensor selection & installation, testing, data and signal processing, and model correlation). Perform root-cause analysis on test failures and develop hardware mitigations. Participate in design review and provide feedback to ensure design objectives are met. Work closely with electrical, software, manufacturing, and nuclear engineers to ensure designs are effectively integrated with overall system requirements. Basic Qualifications Evidence of exceptional ability (prior projects, portfolio of work, completed products, etc). Bachelor’s degree in Mechanical Engineering or a related field. 3+ years of mechanical engineering experience via project team, research, internship, and/or professional experience. 1+ year of experience in structural dynamic analysis or modeling using FEA tools such as Ansys, Femap, Nastran, Abaqus, LS-Dyna, or similar. Excellent problem-solving and communication skills for cross-functional collaboration.   Preferred Skills and Experience Strong understanding of engineering fundamentals. Hands-on experience analyzing data or building hardware. Experience with vibration and shock testing.  Proficiency with FEA and simulation software (e.g., Ansys, Femap, Nastran, Abaqus, LS-Dyna, or similar) and CAD tools such as SolidWorks. Backgrounds in turbomachinery, materials science, or metallurgy. Ability to perform trade studies and make clear recommendations using first principles and engineering fundamentals even with partial information. Experience in a fast-paced engineering environment or a highly technical role requiring a resourceful, entrepreneurial approach to complete tasks within tight timeframes or budget constraints. Additional Requirements Ability to work extended hours and weekends as necessary.
