Job Overview

We are looking for a ​Senior Mechanical Thermal Design Engineer​ on behalf of and in support to our client for their location in ​either Rome, Milan or Turin, Italy.​ 

 

The Mechanical/Thermo Engineer’s primary responsibility will be contributing to the development of OHB ITALIA’s satellite mechanical systems with a focus on thermal design and analysis. This engineer will be involved in the full lifecycle of development, from requirements definition through operations. Being at the cutting edge of space technology, we need someone who is eager to learn, grow, and take on new and potentially unfamiliar challenges. 

 

The Senior Mechanical Thermal Engineer will operate under the leadership of the MTS Architect. 

The successful candidate will be tasked with, but not limited to: 

  • Spacecraft subsystem mechanical and thermal design; 

  • Design and model primary and secondary structural parts, space mechanical thermal systems and equipment, in compliance with rules and best practices; 

  • Incorporate all Avionics components, harnessing and Payload/RF interconnect sub-systems into spacecraft bus design; 

  • Support trade off investigations; 

  • Interface with other subsystem owners for the design of interface requirements, identify and implement design solutions; 

  • Detail mechanical and thermal design for spacecraft composite panels, brackets, hardware, machined parts, Thermal Control system and various mechanical components; 

  • Create detailed design documentation for component manufacturing, assembly and test; 

  • Produce detail drawings, assembly drawings and bills of materials in accordance with the company’s methodological rule; 

  • Conduct detailed tolerance analyses, clearance/interference checks; 

  • Provide ongoing support during S/C assembly, integration, and test; 

  • Support detailed tracking spreadsheet for system mass properties (mass, CG, MOIs); 

  • Research options for appropriate materials and surface treatments for mechanical component design to comply with mission performance requirements; 

  • Support qualification plans (acoustic, vibration, shock, static load tests, thermal tests) to verify structural and thermal margins of safety, and correlation to analysis models; 

  • Develop thermal systems for new and heritage satellite systems. Including thermal radiators (fixed and deployable), heat pipe systems, electrical heaters, temperature sensors, etc.; 

  • Implement thermal design changes required to support new payloads and payload interface units compatible with heritage satellite systems; 

  • Prepare Mathematical models (CAD, GMM/TMM); 

  • Perform thermal analysis of for on-ground test and on-orbit temperature predictions; 

  • Develop thermal test plans, support thermal vacuum / thermal balance testing, and correlate thermal models with test data; 

  • Validate thermal models through prototype/PFM/QM/FM testing; 

  • Support the development of subsystem level requirements and requirement flow-down to the various components and parts as necessary – in all phases of the development lifecycle with particular emphasis on Design for Cost/Design for Manufacturability/Design for Test approaches; 

  • Ensure the maximum reuse of the existing OHB ITALIA heritage products and, if necessary, identify the need for modification.
