Powertrain Simulation Engineer (all genders)

About this role

STARK is a European defence technology company building the next generation of unmanned systems. We design, develop and manufacture software-defined, mass-scalable and cost-effective platforms that give NATO operators a decisive edge in highly contested environments. We are focused on delivering deployable, high-performance capability — not future promises. In a time of rising threats, our work strengthens the technological edge of NATO Allies and their partners.

As a Powertrain Simulation Engineer, you will be the driving force behind predicting, optimizing, and validating the performance of our electric Powertrain Systems (propulsion, invertor, battery and cells) . You will manage the development and execution of complex 1D multi-physics models to simulate aggressive flight profiles and powertrain behaviors. You will build simulation pipelines, automate data analysis, and conduct virtual testing to guide architectural decisions and validate system capabilities before physical hardware is built.

1D Model Development & Simulation: Design, build, and maintain high-fidelity 1D models of the complete electric powertrain (including batteries, inverters, electric motors, and thermal management systems) using industry-standard tools. Performance & Mission Analysis: Execute standard and custom simulation profiles—including high-power continuous discharge (simulating hover/climb), dynamic pulse loading, and extreme temperature conditions—to evaluate system-level performance and efficiency.

Architecture & Optimization : Conduct trade studies and sensitivity analyses to optimize powertrain component sizing, gear ratios, voltage levels, and thermal cooling strategies to maximize range and payload. Data Validation & Correlation: Work closely with the hardware test engineering team (e.g., Dyno and Battery Lab) to correlate 1D simulation results with empirical test data, continuously improving model accuracy and reliability.

Controls & HIL Support: Provide high-fidelity plant models to the firmware and systems teams to support the development of control algorithms and Software/Hardware-in-the-Loop (SIL/HIL) testing. Toolchain & Pipeline Automation: Develop scripts to automate the execution of complex simulation matrices, post-processing of results, and generation of performance reports. Education: Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Electrical Engineering, or a related technical field.
