Turbomachinery Design Engineer

Parque Industrial de Elche (Poligono Industrial), Spain


As a Turbomachinery Design Engineer, you will be responsible for designing components of the propulsion system related to turbomachinery, including turbine and pumps. Your mission will involve developing high-performance turbomachinery designs to support our innovative microlauncher space vehicles. 


  • Design, build, and test turbopump hardware for MIURA 5 first/second stage liquid propellant rocket engines (TEPREL-C and TEPREL-C Vac). 
  • Work closely with the propulsion team to assure functional integration of the turbomachinery components in the engine system. 
  • Generate detail part production drawings to meet functional requirements by use of tolerance stackups. 
  • Build up and own turbomachine tolerance stackup, incorporating information from operational simulations to understand critical interface clearances and inform manufacturing and assembly choices. 
  • Elaborate, update and review engineering documentation including engineering models and drawings. 
  • Evaluate hardware nonconforming conditions providing written dispositions for development, production, test, and postproduction discrepancies considering design requirements, safety, quality, cost and schedule. 
  • Write, review, and update work instructions for assembly, handling, inspection of turbopump assemblies (both intermediate test articles and flight hardware). 
  • Provide feedback to identify, improve performance, increase reliability or manufacturability, and assembly at design level and operational level. 
  • Interface with vendor or in-house fabrication and assembly teams during design and prototype hardware builds. Incorporate any producibility lessons learned by design change and drawing revision. 
  • Generate documentation, including user guides, guidelines and user manuals for internal customers use.  
  • Generate documentation for formal program development reviews.

Required Knowledge

  • Aerospace Engineering bachelor’s degree. 
  • > 5 years of experience using CAD to design parts/assemblies (SIEMENS NX preferred). 
  • Fluency in English, both written and oral, and excellent communication skills

Required Competencies

  • Knowledge of CAD software and engineering principles, as well as manufacturing processes for turbomachinery. 
  • Manage suppliers for the following but not limited assembly/ fabrication tooling support, rotor balance, casting, bearings and seals. 
  • Experience in one or more of the following: 
  • Mechanical design of turbomachinery 
  • Design of Bearings and Seals / Mechanical Elements for rocket turbopump application. 
  • Manufacturing / producibility of turbopump hardware. 


  • Location: Elche 
  • Full time position  
  • Flexibility and willingness to travel domestically and internationally as required, in particular to French Guiana (FR), during implementation phase
