At ISPTech, we’re shaping the future of space propulsion. As a propulsion systems engineering intern, you’ll gain hands-on experience in cutting-edge projects that push the boundaries of technology for CubeSats and SmallSats. You will take ownership of full subsystems from initial fluid schematic design to detailed CAD modeling and structural evaluation. You’ll work alongside experienced engineers, contribute to real missions, and learn what it takes to deliver reliable propulsion systems for space applications.
Your Key Responsibilities - CAD & Technical Drawing Creation: Model system components and assemblies, producing production-ready technical drawings using Geometric Dimensioning and Tolerancing (GD&T).
- Component Selection & Specification: Trade, size, and specify critical fluid system and mechanical hardware, including tanks, control valves, and temperature sensors.
- Fluid System Architecture & P&IDs: Create and maintain Piping and Instrumentation Diagrams (P&IDs)
- Structural Design & Analysis: Conduct preliminary structural hand calculations and/or Finite Element Analysis (FEA) to verify hardware integrity under launch loads, vibration, and thermal environments.
- Electrical & Instrumentation Interfacing: Define and design electrical interfaces for propulsion components, specifying wire harnesses, connector types, and pinouts for power, telemetry, and command control.
- Cross-Functional Collaboration: Coordinate with manufacturing, test, and system safety teams to ensure designs meet assembly, testing, and operational constraints.
- Studying aerospace engineering, mechanical engineering, industrial engineering or a related field
- Proficiency in 3D CAD software (e.g. Fusion, NX, CATIA, or similar) and a foundational understanding of GD&T principles.
- Proactive, self-directed working style, able to manage complex tasks independently
- Familiarity with fluid system schematics (P&IDs) and common fluid/pneumatic hardware components.
- Strong verbal and written communication skills for technical documentation and design reviews.
- Fluent in English, German is a plus
- Ideally: Experience working in a student (rocketry) team
- An exciting work environment encompassing the whole process from the development, building, and launch of space propulsion systems
- Flexible working time
- Combination of working in the office, at home, and on the go
- Professional skills development through a broad base of responsibilities and freedom
- Engage directly and actively participate in the end-to-end development processes of an expanding NewSpace start-up
