About the Job

Requirements

A bachelor's degree in Aerospace Engineering, Mechanical Engineering, Physics, Math, or a related field.
Seven or more years of experience in modeling and simulation of physical systems.
Proficiency in C++ and Python.
A strong understanding of dynamics, thermodynamics, and/or fluid mechanics.
Experience with version control systems such as Git.
Experience with LabVIEW.

Responsibilities

Develop and maintain high-fidelity simulations of space vehicle dynamics, sensors, actuators, propulsion systems, and potentially other subsystems.
Develop physics-based models of vehicle dynamics, reaction systems, propulsion systems, and other subsystems as needed.
Integrate the simulation framework into hardware-in-the-loop testbeds.
Collaborate with engineers across disciplines to validate simulation models and behaviors against analysis and test data.
Support system-level analysis, trade studies, and performance assessments.
Contribute to software and tool development to improve simulation workflows.
Provide simulation support for verification and validation of flight software.
Participate in simulation reviews, test readiness reviews, and mission dress rehearsals.

As a Simulation Engineer, you will be responsible for developing and maintaining high-fidelity simulations of space vehicle dynamics, sensors, actuators, and propulsion systems, with the potential to expand into other subsystems. You will work closely with GNC, software, and test teams to ensure accurate modeling and analysis to support design, verification, and mission planning efforts for Mira, Helios, and more.

About the Company

Impulse Space

In-space propulsion and payload mobility

Impulse Space builds in-space mobility services and propulsion to move payloads after launch. Its products include Mira for precise maneuvering and rendezvous, Helios high-energy kick stage, Caravan rideshare to higher-energy orbits, and propulsion lines Saiph, Deneb, and Rigel. These tools act as in-space tugs and stages to push, dock, and deploy payloads in orbit. Led by SpaceX veteran Tom Mueller, Impulse Space uses flight-proven hardware and a growing network of facilities to make reaching higher-energy orbits faster and cheaper, expanding access for customers.
