What is numerical modeling?

A Numerical Modeling job involves developing and using mathematical models to simulate real-world physical, biological, or engineering systems. Professionals in this field use computational techniques to analyze complex problems, predict behaviors, and optimize designs. They often work with software tools like MATLAB, Python, or specialized simulation programs and apply knowledge from physics, mathematics, and engineering. Numerical modelers are employed in various industries, including aerospace, climate science, finance, and healthcare.

What are the typical daily tasks for someone working in numerical modeling?

Professionals in Numerical Modeling typically spend their days designing and implementing computational models, running simulations, and analyzing data to solve real-world engineering or scientific problems. They often collaborate with other engineers, scientists, or project managers to ensure that models accurately represent complex systems and align with project objectives. Tasks may also include validating models against experimental data, troubleshooting numerical issues, and preparing technical reports or presentations. This role requires a mix of independent research, teamwork, and continuous communication to deliver effective solutions.

What are the key skills and qualifications needed to thrive in numerical modeling, and why are they important?

To excel in Numerical Modeling, a deep understanding of mathematics, physics, and computational methods, often supported by a degree in engineering or science, is essential. Familiarity with programming languages such as Python, MATLAB, or C++, as well as experience with simulation software and numerical analysis tools, is commonly required. Strong problem-solving abilities, attention to detail, and the ability to clearly communicate complex concepts are valuable soft skills in this field. These competencies ensure accurate model development and collaboration within interdisciplinary teams, driving successful real-world solutions.

Job description

About the Company:
We are a stealth-mode Aerospace & Defense startup headquartered in Gardena, CA. Our founding team hails from SpaceX, Anduril, and Lockheed Martin, and we are backed by Joint Staff-level military leadership and several Silicon Valley firms. With a world-class business development & leadership team already in place, we are well positioned to capitalize on already overwhelming demand.
Job Overview:
As a GNC Engineer focused on Simulations, you will lead the development of high-fidelity physics-based simulations for end-to-end missile flight and guidance validation. These simulations serve as a digital proving ground for our flight software, autonomy stack, and control systems-enabling us to iterate rapidly and validate in silico what would otherwise require expensive, slow, or impossible real-world testing.
You'll own simulation architecture, real-time physics integration, and testbed development. If you're comfortable writing performant simulation code in Rust and Python, and you're looking to do impactful work on a system that must work the first time, this is your chance.
Key Responsibilities:
  • Design high-performance 6-DOF flight and physics simulations
  • Build simulation components that replicate real-world dynamics and sensor behavior
  • Integrate guidance, navigation, and control (GNC) logic into full-stack simulations
  • Develop Monte Carlo, Hardware-in-the-Loop (HITL), and closed-loop test infrastructure
  • Collaborate closely with flight software, autonomy, and hardware teams to ensure simulation fidelity matches real-world constraints
  • Create tooling to support scenario authoring, data visualization, and performance analysis
  • Own simulation pipeline performance and determinism across a wide range of conditions

Basic Qualifications:
  • Bachelor's degree in Computer Science or a related technical field
  • 5+ years of experience building simulations or numerical modeling frameworks
  • Proficient in Rust and Python for performance-critical and test-driven development
  • Understanding of rigid body dynamics, kinematics, numerical integration, and physics
  • Experience building tools for flight dynamics, aerospace simulation, or autonomous systems

Preferred Qualifications:
  • Experience with Monte Carlo testing, sensor emulation, and closed-loop control validation
  • Familiarity with real-time systems, latency-sensitive architectures, or distributed simulation
  • Experience deploying or validating autonomous systems (missiles, drones, satellites, or vehicles)
  • Familiarity with Rust game engines or physics libraries (e.g., Rapier, Bevy)
  • Exposure to 3D rendering for simulation visualization (e.g., WebGL, OpenGL, Three.js)
  • Contributions to aerospace open source or simulation frameworks (e.g., JSBSim, Gazebo)

Itar Requirements
  • To conform to U.S. Government export regulations, applicant must be a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (aka green card holder), (iii) Refugee under 8 U.S.C.
  • 1157, or (iv) Asylee under 8 U.S.C.
  • 1158, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.
