6-DoF Flight Simulation & Performance Engineer

Arbeitnow; Zürich; On-site; CHF 110,000 - 170,000; Full time

Job summary

Arbeitnow is seeking a highly capable Flight Physics & Performance Engineer to develop, validate, and maintain high‑fidelity 6‑DoF simulation environments for missile performance analysis. You will implement flight physics and guidance models, and ensure tools are robust, scalable, and aligned with system requirements.

This role calls for strong analytical skills, hands‑on experience with simulation toolchains, and a passion for advancing modelling capabilities behind next‑generation missile

Qualifications

• MSc in Aerospace Engineering, Mechanical Engineering, Applied Mathematics, or related field.
• Proven experience in 6-DoF simulations for aerospace or missile systems.
• Strong understanding of flight mechanics, aerodynamics, propulsion models, rigid-body dynamics.

Responsibilities

• Develop, maintain, and extend 6-DoF simulation environments for missile performance assessment, system trade studies, and design validation.
• Implement and refine flight physics models, including aerodynamics, propulsion behavior, actuator dynamics, sensor models, and environmental effects.
• Build and integrate simulation tools and analysis utilities to support SIL, CIL, and HIL test configurations.
• Define, decompose, and manage system and simulation requirements using DOORS NG or similar systems engineering tools.
• Generate clear, structured, and technically rigorous documentation, covering modelling assumptions, equations of motion, validation results, and verification.
• Produce and execute test cases for requirement verification across multiple simulation levels (SIL, CIL, HIL).
• Work cross-functionally with GNC, Systems Engineering, Software, and Flight Dynamics teams to ensure model fidelity and alignment with system needs.
• Participate in design and technical reviews, presenting simulation methodologies, performance outcomes, and model limitations.
• Support algorithm development teams by providing simulation environments, interfaces, and validation scenarios.
• Actively contribute to continuous improvement of internal simulation capabilities, toolchains, and workflows.
• Represent the simulation domain in external collaborations, technical meetings, or strategic advisory groups when required.
