How to apply for Senior Instrument Scientist, Simulation

About Muon Space

Muon Space is revolutionizing climate action with cutting-edge Earth-sensing satellite technology. As a company, it offers the unique opportunity to work at the intersection of space systems and climate impact, translating physics into orbital capability. Employees join a mission-driven team where their work directly contributes to understanding and addressing climate change.

About the role

As the Senior Instrument Scientist for Simulation, you will own the end-to-end simulation and modeling that connects optical, detector, and scanner physics to on-orbit performance. You will build and maintain virtual instrument and digital twin representations of on-orbit hardware, define flight software inputs, and support anomaly resolution. This role is critical for ensuring that Muon's instruments meet their performance requirements and for enabling rapid diagnosis of on-orbit issues.

A typical day

A typical day might involve refining a simulation model to incorporate new detector characterization data, collaborating with optical engineers to validate performance predictions, and participating in a telecon to discuss flight software inputs for a new operating mode. You might also spend time investigating a recent on-orbit anomaly, updating the digital twin accordingly, and preparing for your upcoming on-call rotation.

Who Muon Space is looking for

• **Advanced degree (PhD preferred) in physics, optics, or a related engineering field** with a strong foundation in electro-optical/infrared instrument physics.
• **Proven experience in developing end-to-end instrument performance simulations**, including optical, detector, and scanner modeling, ideally for space-based systems.
• **Proficiency in simulation tools and languages** such as Python, MATLAB, or C++, and experience with digital twin or virtual instrument concepts.
• **Familiarity with on-orbit anomaly resolution and flight software inputs**, and willingness to participate in a 24/7 on-call rotation (approximately one week every six weeks).

Tips for this application

• Highlight any experience you have with space-based instrument simulation, especially if it involves end-to-end modeling from physics to on-orbit performance.
• Emphasize your ability to build digital twins or virtual instruments, and mention specific tools or frameworks you've used.
• Demonstrate your understanding of the on-call rotation requirement and your ability to support anomaly resolution in a 24/7 environment.
• Tailor your resume to include keywords from the job description such as 'optical', 'detector', 'scanner physics', 'digital twin', and 'flight software inputs'.
• If you have experience with climate or Earth-sensing missions, be sure to connect your work to Muon Space's climate action mission.

What to cover in your cover letter

["Your specific experience in developing end-to-end instrument simulations for EO/IR systems, and how it aligns with Muon's need to predict on-orbit capability.", "Concrete examples of how you've built or maintained digital twin representations and kept them aligned with as-built performance.", 'Your approach to defining flight software inputs based on simulation results, and any experience you have with on-orbit anomaly investigation.', "Your enthusiasm for Muon Space's mission to revolutionize climate action through satellite technology, and how your skills can contribute."]

Research before applying

• Learn about Muon Space's current and planned satellite missions, especially those related to climate and Earth sensing, to understand the specific instruments you'd be simulating.
• Research the Electro-Optical/Infrared Instruments organization at Muon Space and any public information about their instrument design and performance.
• Understand the basics of digital twin technology and how it's applied in space systems, as this is a key aspect of the role.
• Look into Muon Space's company culture and values, especially around innovation, climate impact, and remote work, to tailor your application.

Likely interview topics

Based on the job description, expect questions about:

• Can you walk us through a complex instrument simulation you developed? What were the key challenges and how did you validate the model?
• How would you approach building a digital twin for an on-orbit instrument? What data and processes would you prioritize?
• Describe a time when you had to support an on-orbit anomaly. How did you diagnose the issue and feed lessons back into your models?
• What experience do you have with defining flight software inputs for operating modes, sensor readout, or scanner control?
• How do you ensure that your simulation models remain aligned with as-built performance throughout the instrument's life cycle?

Common mistakes to avoid

• Avoid generic statements about your simulation experience; instead, provide specific examples that demonstrate your ability to model EO/IR instruments end-to-end.
• Don't downplay the on-call rotation requirement; show that you understand and are willing to commit to it.
• Avoid focusing only on theoretical modeling without connecting it to practical on-orbit performance and anomaly resolution.
