External Job Description

About POWERTECH

POWERTECH is a center of excellence for propulsion technologies, specializing in the design, engineering, and manufacturing of combustion engines, expendable turbojet engines, and turbofan engines for a wide range of aerospace, defence, and autonomous applications, including fixed- and rotary-wing UAVs and other advanced platforms.

Role Overview

PowerTech is seeking a Simulation Engineer to join the Advanced Fluid Systems team, focused on the development of next-generation gas turbine propulsion systems. The team is responsible for module, component, subsystem, and full system development, supporting both current and future product portfolios. This role centers on the simulation, design, and development of gas turbine combustion systems, with emphasis on fluid dynamics, combustion dynamics, thermodynamics, heat transfer, turbomachinery, aerodynamics, and fuel systems.

Key Responsibilities

• Perform advanced simulations for gas turbine combustion systems, including high Mach number combustion environments


• Apply fundamental and applied CFD methods to support combustor aerodynamic design and optimization


• Contribute to the design and development of modules, components, subsystems, and full propulsion systems


• Use 1D and reduced-order tools alongside high-fidelity CFD to support system-level analysis


• Collaborate with cross-functional engineering teams on design, analysis, and validation activities


• Support engine and component testing, including pre-test prediction and post-test analysis


• Contribute to the advancement of future propulsion technologies while supporting existing products

Required Qualifications

• Bachelor’s or Master’s degree in Aerospace Engineering, Mechanical Engineering, or a related field (Master’s or PhD preferred)


• Relevant industry experience in gas turbine or combustion system development (considered a strong plus)


• Strong understanding of combustor aerodynamics, thermoacoustic and combustion fundamentals


• Hands-on experience with CFD tools and methods applied to gas turbine combustion systems


• Solid grounding in fluid dynamics, thermodynamics, and heat transfer

Preferred Qualifications

• Experience in the design and development of gas turbine combustion systems


• Experience in concept development for afterburner and ramjet propulsion systems (considered a strong plus)


• Familiarity with high Mach number combustion environments and scramjet technologies


• Experience using 1D/system-level simulation tools


• Exposure to engine or component testing and validation processes


• Background in military or defense-related combustion systems

Key Skills

• Strong analytical and problem-solving capabilities


• Ability to bridge fundamental theory with applied engineering


• Experience working in multidisciplinary engineering environments


• Effective communication and collaboration skills
