Physics Modeling And Simulation Engineer Zenno is seeking a sharp, motivated person to carry out physics modeling and simulation work supporting the development and application of our space technologies. The work will include astrodynamics, orbital mechanics, spacecraft attitude dynamics and other physics-based modeling of spacecraft and the space environment. This is a highly independent role. You will be given ownership of technical assignments and will be responsible for taking them from an initial objective through to a completed, defensible result. You will have significant freedom to determine the modeling approach, methods and tools used, while being accountable for the quality and on-time delivery of your work.
Your responsibilities will include:
Own physics modeling and simulation assignments from definition through to delivery.
Build and run numerical simulations of spacecraft orbits, attitude dynamics and physical interactions in the space environment.
Translate technical questions into appropriate models, assumptions, calculations and simulation approaches.
Research unfamiliar areas of physics and engineering as required to solve assigned problems.
Test assumptions, validate models and perform appropriate sensitivity and sanity checks on results.
Analyze simulation outputs and draw clear, technically defensible conclusions.
Clearly document modeling methods, assumptions, limitations and results so that work can be reviewed and reproduced.
Present findings clearly to technical and non-technical stakeholders.
Manage your own technical work, priorities and deadlines, identifying risks or blockers early and taking responsibility for agreed deliverables.
You must have strong physics and mathematical reasoning, good computational skills and the ability to learn unfamiliar technical material quickly. Experience with Python or another scientific computing language is preferred. We are looking for someone who combines technical curiosity with strong execution. You should be comfortable working with limited supervision, making technical decisions independently and being accountable for delivering accurate work by agreed deadlines. Remote work permitted; attendance at our Torrance office is required at least once a week. Reports directly to the Co-founder and Chief Product Officer. Desired start date: October 19th, 2026.
