We are seeking a Mechanical Engineer to own the development of mechanical systems flying on Kepler spacecraft. In this role you will be responsible for the mechanical design and prototyping as well as the structural and thermal analysis of Kepler hardware.
Key Responsibilities:
- Develop mechanical solutions for spacecraft and satellite subsystems from initial concept through to flight qualification
- Design and evaluate thermal and structural solutions using robust simulation models, supported by appropriate analysis tools and calculations
- Demonstrate and document margins of safety against system requirements (e.g. component temperature limits, vibration, static loading, thermal cycling)
- Create parts and assemblies, leveraging CAD tools to draft mechanical drawings for both production and interface control, as well as associated bills of material
- Work closely with other cross-functional engineering teams (RF, electrical, systems, etc.) to develop full product solutions
- Define verification methods and success criteria, including plans to mitigate technical risks through both simulation and physical testing
- Own prototype build and test to generate design feedback and correlate simulation models
- Act as peer reviewer providing technical mentorship to junior members of the team
Required Skills & Qualifications:
- 5+ years of relevant mechanical design experience
- Bachelor's degree in mechanical engineering, mechatronics engineering, or equivalent
- Understanding of design principles for heat transfer, temperature control, statics, and dynamics
- Experience in verifying designs through Finite Element Analysis and testing
- Experience with one or more CAD tools (Onshape, Creo, Solidworks, etc.)
- Understanding of design for manufacturing and assembly practices
- Strong communication and documentation skills working in a multidisciplinary team
- Comfortable in an R&D lab environment
- Comfortable using basic hand and power tools
Bonus Points:
- Knowledge and/or experience in design for space applications
- Experience using Simcenter 3D, Simcenter/NX NASTRAN, Simcenter 3D Space Systems Thermal, etc.
- Experience in spacecraft/satellite level thermal and structural analysis and qualification
- Familiarity with ESA ECSS or NASA thermal and structural standards
