iRocket is developing fully autonomous, fully reusable small launch vehicles to provide responsive, cost-effective access to space. Our mission is to catalyze a new era of space exploration through innovation in propulsion, structures, and sustainable launch systems. The Role: We are seeking a Mechanical Engineer to contribute to the design, development, and transition of mechanical components and systems from development through production. You’ll partner with propulsion, manufacturing, integration, and test teams to help deliver high-performance, reliable rocket hardware. • Act as Responsible Engineer for key subsystems or components (e.g., valves, mechanical assemblies) • Advance design of parts and assemblies: create CAD models, drawings, and associated documentation • Perform mechanical analyses, calculations, and design iterations to meet performance, mass, and reliability targets • Collaborate with manufacturing teams to ensure designs are manufacturable, and iterate designs based on feedback • Support fabrication, post-processing, inspection, and tolerance verification of parts • Assist with integration, assembly, and test of mechanical and propulsion subsystems • Create schematics, document design and manufacturing processes, and maintain records • Participate in test campaigns, support troubleshooting, and analyze results • Communicate progress, issues, and tradeoffs clearly across cross-functional teams • Ensure safe practices and adherence to PPE and safety standards in lab, shop, and test areas Requirements • Bachelor’s degree in Mechanical Engineering or a related engineering discipline • 3+ years of experience in mechanical design, development, fabrication, assembly, or test • Proficiency in CAD • Knowledge of GD&T, tolerance design, part and assembly drawings • Strong problem solving, analytical thinking, and collaboration skills • Excellent written and verbal communication skills • Ability to manage multiple tasks in a fast-paced environment • Experience in aerospace, propulsion, or high-reliability systems • Hands-on engineering background (design to bench to manufacturing) • Experience with simulation or analysis tools (e.g. ANSYS, FEA) • Experience scripting or using tools such as MATLAB or Python • Comfort iterating quickly, learning from experiments, and working through ambiguity Benefits • Health Care Plan (Medical, Dental & Vision) • Retirement Plan (401k, IRA) • Life Insurance (Basic, Voluntary & AD&D) • Paid Time Off (Vacation, Sick & Public Holidays) • Family Leave (Maternity, Paternity) • Short Term & Long Term Disability • Wellness Resources
