What you'll do
- Perform structural, mechanical, and thermal analysis using FEA tools such as ANSYS, Abaqus, COMSOL, or equivalent.
- Carry out fluid-system analysis and thermal modelling to support mechanical design decisions.
- Assess vibration, stability, and dynamic behaviour of mechanical assemblies and identify potential design risks.
- Validate simulation outputs against design requirements, engineering standards, and expected operating conditions.
- Translate analysis results into practical design recommendations that improve performance, safety, manufacturability, and system compatibility.
- Develop and maintain 3D CAD models and engineering drawings using Autodesk Inventor or a similar tool.
- Define and execute verification activities, prepare analysis reports, and provide simulation evidence for design reviews.
- Collaborate with mechanical, systems, and project engineering teams to define interfaces, communicate results, and support multidisciplinary design decisions.
What we're looking for
- Analytical and technically rigorous mechanical engineer who enjoys solving complex engineering problems through modelling and simulation.
- Methodical approach to setting up analyses, checking assumptions, interpreting results, and documenting conclusions.
- Ability to translate complex simulation outputs into clear, actionable engineering decisions.
- Ability to identify design risks early and proactively propose practical mitigation strategies.
- Clear communication with both technical and non-technical stakeholders, adapting the level of detail to the audience.
- Effective collaboration across mechanical, systems, and project engineering disciplines.
- Ownership of the quality, traceability, and accuracy of analysis work and design evidence.
- Detail-oriented and committed to applying sound engineering fundamentals and standards consistently.
Nice to have
- Experience performing structural, thermal, dynamic, and fluid-system analysis in a professional mechanical engineering environment.
- Proficiency with FEA tools such as ANSYS, Abaqus, COMSOL, or equivalent, together with experience validating and documenting simulation results.
- Experience with 3D CAD tools, preferably Autodesk Inventor, and the ability to connect analysis outputs with practical mechanical design decisions.
- Knowledge of CFD tools such as ANSYS Fluent or OpenFOAM, vacuum or cryogenic mechanical systems, laser or optical integration, or scientific instrumentation.
- Familiarity with design for manufacture and assembly (DFMA), prototype build and commissioning support, verification planning, and engineering documentation in experimental or multidisciplinary environments.
