Senior Instrument Scientist, Simulation

About the role Muon's Instrument Science team, part of our broader Electro-Optical/Infrared Instruments organization, defines the science, models and calibrates the instrument, and validates its performance, translating physics into orbital capability from concept through end of life. As our Senior Instrument Scientist responsible for Simulation, you will own the simulation and modeling that connect optical, detector, and scanner physics to on-orbit capability, drive instrument performance prediction, and build the virtual instrument and digital twin representations of our on-orbit hardware. Responsibilities • Develop and maintain end-to-end instrument performance simulations, from optical, detector, and scanner physics through predicted on-orbit capability. • Build and maintain the virtual instrument and digital twin representations of our on-orbit hardware, keeping them aligned with as-built performance. • Define flight software inputs for operating modes, sensor readout, and scanner control based on simulation results. • Support on-orbit performance monitoring and anomaly investigation, feeding lessons learned back into the simulation models. • Participate in a twenty-four-hour, seven-day on-call rotation to support on-orbit anomaly resolution. The on-call rotation is approximately one week every month and a half. Qualifications • Bachelor's, Master's, or doctoral degree in engineering, physics, or a related field, or equivalent experience. • 5+ years of experience coding and simulating performance for imaging systems, remote sensing instruments, or comparable electro-optical hardware. • Experience building instrument performance models or simulations, radiometric, geometric, optical, or systems-level. • Software proficiency in one or more languages, such as Python, Julia, or C++, including experience writing code that others depend on, tested, reviewed, and maintained in a shared codebase. • Strong communication skills, comfortable translating performance predictions into requirements and trade studies across Instrument Systems, Flight Software, and Mission Systems teams. Nice-to-have Skills • Familiarity with flight software concepts, such as operating modes, sensor readout, or scanner and pointing control. • Exposure to radiometric or geometric calibration methodology. • Experience with virtual instruments or digital twin architectures. • Experience supporting on-orbit commissioning, calibration and validation, or fleet performance monitoring and anomaly investigation. • Ability to apply first-principles physics to validate simulation outputs. Salary The salary range for this role is $158,000 - $207,000, plus a competitive equity grant and comprehensive benefits package. Final compensation will be determined based on skills, qualifications, experience, and geographic location as assessed during the interview process.
