How to apply for Principal Mission Architect - International

About Muon Space

Muon Space builds Earth-sensing satellite technology aimed at climate action. The company works on space missions from concept through payload and constellation design. This role focuses on international customers, so the work directly shapes how Muon expands outside the US.

About the role

You lead mission formulation for international opportunities. You work with customers to find their real needs, then direct a team of engineers to turn those needs into a cost-effective space mission. You own top-level mission budgets, requirements, and trade studies, and you travel internationally about 30% of the time.

A typical day

You might run mission-level analyses and trade studies, meet with international customers to clarify needs, and coordinate with instrument and discipline engineers on requirements. Some days focus on constellation or spacecraft performance evaluation; others are spent preparing for or traveling on international business trips.

Who Muon Space is looking for

• Has a B.S. or higher in a related engineering field and experience leading mission-level design for space systems.
• Can run mission-level analyses, own top-level budgets, and define requirements for a full mission and its payloads.
• Is comfortable writing code or using software tools to explore trade studies and answer system design questions.
• Has worked with international customers and can manage a team of engineers to deliver a practical, cost-effective solution.

Tips for this application

• Show one or two mission concepts you led end-to-end, including the top-level budgets you owned and the trade studies you ran.
• Name the software tools and coding languages you used for mission analysis, and describe a specific design question you answered with them.
• Describe your experience with international customers: which countries or regions, what their needs were, and how you translated those needs into requirements.
• Explain how you worked with instrument or payload teams, since the role requires close work with Muon's instrument design team.
• State clearly that you can travel internationally about 30% of the time and note any prior international work travel.

What to cover in your cover letter

['A specific mission concept you developed from customer needs through top-level requirements and budgets.', 'Your experience with international customers and how you identified their true needs.', 'Your technical work in mission-level analysis, trade studies, and constellation or spacecraft performance evaluation.', 'How you led or coordinated a team of engineers across disciplines to deliver a cost-effective design.']

Research before applying

• Review Muon Space's Earth-sensing satellite technology and any public mission or payload details.
• Look up Muon's current and past international work or partnerships, if any are public.
• Read about the climate and Earth-observation data market outside the US to understand customer needs.
• Check the backgrounds of Muon's mission development and instrument design teams to understand how they work.

Likely interview topics

Based on the job description, expect questions about:

• Walk through a mission concept you developed. How did you set top-level budgets and requirements?
• How do you identify a customer's true needs when their stated requirements are unclear or incomplete?
• Describe a trade study you ran with software tools or code. What design question did it answer?
• How do you evaluate spacecraft performance and constellation configuration for a new mission?
• Tell us about a time you worked with an instrument or payload team to balance design constraints.

Common mistakes to avoid

• Applying without showing any mission-level ownership, such as budgets, requirements, or trade studies.
• Listing tools and coding languages without a concrete example of a design question you answered.
• Ignoring the international focus, such as not mentioning customer work outside the US or willingness to travel 30%.
