Junior Mechanical Engineer; m​/f​/d

ATMOS Space Cargo is seeking a Junior Mechanical Engineer to support the design, development, manufacturing, and testing of aerospace‑grade hardware. This is a 1-year fixed‑term role and a great opportunity for an early‑career engineer who wants to gain hands‑on experience across the full hardware development cycle, from concept and design to assembly, testing, and verification.

• You will support the development and refinement of mechanical designs from concept through production, taking into account space‑qualification requirements
• You will create and update detailed 3D CAD models and technical drawings for manufacturing and assembly, preferably in Solid Works
• You will contribute to the design, analysis, and optimisation of structures, mechanisms, and mechanical interfaces with regard to performance, durability, and mass efficiency
• You will support the selection of materials, components, and manufacturing methods in line with aerospace requirements and environmental constraints
• You will assist in prototype builds, assembly, integration activities, and test campaigns
• You will support the execution and documentation of mechanical, structural, and environmental tests, including vibration, thermal cycling, and fit checks
• You will work closely with internal teams such as systems, avionics, and propulsion to support the integration of mechanical subsystems
• You will support technical coordination with suppliers and external partners to clarify specifications and help ensure component quality and compliance
• You will contribute to the continuous improvement of existing designs with regard to performance, reliability, manufacturability, and cost efficiency
• You will help ensure traceability, technical documentation, and compliance with safety, aerospace, and certification‑related requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, or a related field
• First professional experience in mechanical design through internships, working student roles, university projects, or an entry‑level engineering position
• Good knowledge of 3D CAD modelling and technical drawing; experience with Solid Works is a strong plus
• Initial hands‑on experience with mechanical assembly, prototype development, or testing is an advantage
• Solid understanding of mechanical structures, materials, and manufacturing processes
• Interest in designing hardware for demanding environments, including vibration, thermal loads, and other challenging operating conditions
• Ability to understand technical requirements and translate them into practical and robust mechanical designs
• Strong written and spoken English;
  German is a strong plus
• Structured and proactive way of working, with strong problem‑solving skills and a hands‑on mindset
