Mechanical Design Engineer - Advanced Spacecraft Propulsion

Overview

We are an early-stage aerospace startup dedicated to pioneering next-generation spacecraft propulsion technologies for orbital missions. We are expanding our engineering team and seek a Mechanical Design Engineer to lead the mechanical design, development, and qualification of critical propulsion hardware. This role involves full ownership from conceptual design through flight-ready hardware, demanding hands-on engineering with multidisciplinary collaboration across propulsion, systems, and testing teams.

Key Responsibilities

• Lead design of electric propulsion components and spacecraft subsystems mechanically.
• Create precision mechanical parts such as propulsion assemblies, fluid control hardware, and structural frameworks.
• Manage the hardware lifecycle from initial concept, detailed CAD modeling, prototyping, qualification, to flight readiness.
• Produce 3D CAD models, manufacturing blueprints, and GD&T (Geometric Dimensioning and Tolerancing) documentation.
• Conduct structural and thermal performance validations using finite element analysis.
• Select materials and manufacturing techniques suitable for demanding aerospace environments.
• Assemble and test hardware in the lab, overseeing environmental verification including vibration, shock, and thermal vacuum tests.
• Analyze test outcomes, drive design refinements, and iterate hardware through multiple development phases.
• Collaborate closely with propulsion, systems, manufacturing, and test engineering teams to ensure delivery of reliable propulsion systems.

Required Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, or related fields.
• Minimum of 3 years designing complex mechanical hardware.
• Advanced skills in CAD software and finite element analysis tools.
• Experience with structural and thermal analyses.
• Proficient in generating manufacturing drawings and implementing GD&T standards.
• Strong knowledge of mechanical design principles, materials science, and fluid system mechanics.
• Track record designing and testing mechanical assemblies and pressurized components.
• Problem-solving aptitude using fundamental engineering principles.
• Ability to thrive in a fast-moving, collaborative engineering environment with significant ownership.

Preferred Experience

• Background in aerospace or spacecraft hardware development.
• Experience specifically with electric propulsion or high-performance propulsion systems hardware design.
• Hands-on skills in building, assembling, and testing precision mechanical systems.
• Familiarity with environmental qualification tests including vibration, shock, and thermal vacuum.
• Involvement in hardware development from prototype through production stages.
• Exposure to startup or early-stage product development cultures.

Benefits and Compensation

• Competitive base salary ranging from $130,000 to $180,000 depending on experience and skills.
• Equity via stock options offering ownership participation.
• Comprehensive medical, dental, and vision insurance coverage.
• 401(k) retirement savings plan.
• Paid time off for work-life balance.
• Opportunity to own and influence flight hardware development through launch.
• Direct collaboration with seasoned aerospace engineers promoting significant career growth.
