Our patented X-Engine architecture delivers a lighter smaller and more efficient solution compared to traditional engines - enabling new capabilities across aerospace defense and clean power not just building engines were pushing the boundaries of innovation in power and propulsion. As part of our team youll work alongside passionate engineers designers and researchers committed to solving hard problems and bringing cutting-edge technology to youre excited about clean-sheet engine design real R&D challenges and the opportunity to make a direct impact in a small agile team - this is your chance to help build something truly revolutionary.

Position Overview :

The Senior Simulation Engineer will lead the design development and validation of rotary engine sealing systems and related components. This role involves applying advanced principles of tribology materials science and dynamic simulation to optimize seal performance durability and reliability under demanding operating conditions. The position requires close collaboration with manufacturing and engineering teams hands-on problem solving during testing and the ability to communicate technical findings effectively. The ideal candidate will have deep expertise in high-temperature engine components strong analytical skills and a proven track record in independent and collaborative R&D projects.

Responsibilities :

• Rotary Seal Development : Lead the design and refinement of the rotary engine sealing system including Apex Seals and Face Seals.
• Journal Bearing Design : Contribute to the design material selection and optimization of journal bearings. Analyze bearing loads clearances oil flow and housing deflection to ensure hydrodynamic stability and durability.
• Tribology and Wear : Apply advanced principles of tribology to minimize friction optimize lubrication and predict / mitigate wear on seals and housing surfaces.
• Dynamic Simulation : Develop and utilize 1D / 3D dynamic models to analyze seal motion contact pressure leakage and flutter under various operating conditions (speed temperature load).
• Materials and Manufacturing : Specify and qualify materials appropriate for high-temperature high-pressure sliding contact and collaborate with manufacturing partners on component specifications.
• Thermal and Structural Analysis (FEA / CFD) : Utilize Finite Element Analysis (FEA) to assess thermal distortion structural integrity and mechanical stress on sealing components and their supporting structures (rotor housing).
• Validation and Testing : Design execute and analyze engine test plans focused on seal performance durability and friction.
• Troubleshooting : Diagnose and resolve complex sealing-related engine performance issues identified during dyno testing and field trials.
• Communicate findings clearly and effectively to stakeholders.
