About The Role

Your Main Responsibilities

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,

a

nd 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.

Your Qualification

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
