Longshot Space Technologies Corporation

Get AI-powered advice on this job and more exclusive features. Longshot Space Technologies is at the cutting edge of low-cost space access and hypersonics. We are developing a novel space launch system that accelerates mass over a long distance. Using our technology, we plan to provide affordable launch services for satellites, cargo, and future space infrastructure. We aim to enable a future where humans can reach for the stars. Position Overview We are looking for a Simulation Engineer with a strong background in CFD and FEA to help model the complex, transient, and high-pressure environments our hardware operates in. You will lead the development of tools and simulations to support design validation, drive design decisions, and correlate against physical test data. Your models will help shape the design of the booster system, projectile aerodynamics, gas composition, chamber dynamics, orifice tuning, and high-speed airflow regimes. This is a key technical role that will help unlock data-informed decisions for both engineering and customer mission planning. Key Responsibilities Build and validate CFD models of booster dynamics, chamber pressure profiles, and projectile aerodynamics. Analyze timing, spacing, and angle effects on gas injection and projectile acceleration. Collaborate with hardware teams to simulate system responses and correlate against test data. Develop structural FEA models of projectile components and launcher interfaces. Support design of gas recapture systems and optimization of nozzle/orifice configurations. Provide mission-level modeling to inform customer payload planning and system requirements. Create detailed reports and presentations to guide internal and external decision-making. Preferred Experience & Qualifications Bachelor's or Master's degree in Mechanical, Aerospace, or related field. Experience with CFD tools such as Converge, StarCCM+, OpenFOAM, or equivalent. FEA experience with ANSYS, Abaqus, or similar tools. Understanding of compressible flow, high-Mach dynamics, and transient multiphysics systems. Experience modeling high-pressure gases, phase changes, or injector flows is a plus. Familiarity with scripting and automation of simulation workflows (e.g., Python, Bash). Strong analytical mindset and communication skills. What You'll Gain Ownership of simulation infrastructure that guides critical hardware design. Opportunities to validate models through hands-on testing and real-world data. A core role in shaping Longshot's technical roadmap and external mission offerings.
