Turbomachinery Structural Engineer

Parque Industrial de Elche (Poligono Industrial), Spain


As a Turbomachinery Structural Engineer, you will be responsible for performing a wide range of analyses and assessments related to the structural integrity, performance, and reliability of turbomachinery components and systems, with a focus on ANSYS Mechanical for Finite Element Analysis (FEA). Your mission will involve developing, validate and optimize 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. 
  • Conduct in-depth Finite Element Analyses (FEA) using ANSYS Mechanical (preferred) for turbomachinery components, including impellers, casings, blades, and other structural elements, to ensure structural integrity, durability, and performance under operating conditions. 
  • Conduct analyses on bearings and mechanical seals, evaluate their performance and reliability under varying load conditions, and propose design modifications or improvements as required. 
  • Work with cryogenic temperatures in the assessment of material behaviour, thermal expansion, and cryogenic sealing requirements for turbomachinery components. 
  • Analyse test data from turbomachinery tests, including modal analysis, blade tip timing, and strain gauge measurements, to validate and refine structural models, identify areas for improvement, and optimize component design.
  • Collaborate with manufacturing and production teams to identify and resolve any manufacturing challenges or issues regarding the turbomachinery components. 
  • Conduct material characterization studies to analyse manufacturing capabilities and compatibility of materials for different turbomachinery components, including machining and additive manufacturing processes. 
  • Write, review, and update work instructions for assembly, handling, inspection of turbopump assemblies (both intermediate test articles and flight hardware).

Required Knowledge

  • Aerospace Engineering bachelor’s degree. 
  • > 5 years of experience using FEM analysis in concert with turbomachinery components (ANSYS Mechanical preferred) 
  • Fluency in English, both written and oral, and excellent communication skills.

Required Competencies

  • Knowledge of FEM software, as well as blade geometry parametrization for turbomachinery components. 

Experience in one or more of the following: 

  • Proficiency in rotordynamics analysis and familiarity with relevant software packages for vibration analysis. 
  • Strong understanding of bearings and mechanical seals, their design principles, and analysis techniques. o Experience in material characterization studies, including analysis of material properties and behaviour for manufacturing processes such as machining and additive manufacturing.


Valued Competencies

  • Strong background in turbomachinery design, analysis, and testing, with a specialization in rocket engines. 
  • Manage suppliers for the following but not limited assembly/ fabrication tooling support, rotor balance, casting, bearings, and seals. 
  • Experience with cryogenic fluids. 
  • Familiarity with gas turbine technologies, including their design principles and performance optimization techniques. 
  • Familiar with manufacturing capabilities (typical tolerances) and processes: turning, milling, drilling, reaming, EDM, grinding, brazing, welding, 3D printing. Familiar with mechanical seals.
