How to apply for Senior Systems Engineer, EO/IR Payloads

About Muon Space

Muon Space builds Earth-sensing satellite technology aimed at climate action. The company works at the intersection of space hardware, remote sensing, and climate data. This role sits in the Mission Innovation team, which explores new payload concepts before they become products.

About the role

You will explore new EO/IR payload and instrument concepts, model and simulate them, and test novel imaging modes. You act as a bridge between Applied Science, Payload Engineering, Product, Mission Systems, and Business Development. The work happens at the earliest stage of the business lifecycle, where you hypothesize and validate how Muon's payloads can solve problems for defense, intelligence, philanthropic, and commercial users.

A typical day

A typical day may involve building or refining a simulation for a new EO/IR payload concept, meeting with Applied Science or Payload Engineering to align on assumptions, and preparing a technical brief for Product or Business Development. You might also run experiments or analyze data to test whether a novel imaging mode is feasible. The exact routine is not described in the job posting, so ask about team cadence and tools during interviews.

Who Muon Space is looking for

• Has senior-level systems engineering experience with EO/IR payloads or instruments, including requirements development and performance modeling.
• Can build simulations and models from scratch to test early-stage payload concepts and novel imaging modes.
• Is comfortable working across disciplines and translating technical findings for product, science, and business stakeholders.
• Has experience with defense, intelligence, philanthropic, or commercial remote sensing applications, or can quickly learn those user needs.

Tips for this application

• Tailor your resume to show EO/IR payload systems engineering work, not general systems engineering. Name specific instruments, bands, or imaging modes you have worked on.
• Include examples of simulations or models you built for early-stage concepts. Describe the tool, the inputs, and what decision the model supported.
• Show cross-functional work with science, product, or business teams. Muon lists these as core to the role.
• Mention any experience with defense, intelligence, philanthropic, or commercial EO/IR end-users. This maps directly to the job description.
• Apply through Muon Space's careers page and check whether they ask for a cover letter or portfolio. If a portfolio is allowed, include a short write-up of one payload concept you modeled.

What to cover in your cover letter

Describe one EO/IR payload concept you took from hypothesis to model or simulation, and what you learned. Explain how you worked with non-engineering stakeholders to shape requirements. Connect your experience to Muon's Earth-sensing and climate focus. State why early-stage concept work appeals to you more than late-stage integration.

Research before applying

• Review Muon Space's current satellite missions and any public payload specifications to understand their existing EO/IR capabilities.
• Look up the backgrounds of the Mission Innovation team or leadership if listed on the company site or LinkedIn.
• Read about Muon's climate and Earth-sensing customers or partners to understand the end-user problems they target.
• Check recent news or publications about Muon Space to see what payload or mission concepts they have discussed publicly.

Likely interview topics

Based on the job description, expect questions about:

• Walk through an EO/IR payload concept you modeled. What assumptions did you make and how did you validate them?
• How do you develop system and payload requirements when the mission is still undefined?
• Describe a time you bridged a gap between a science team and an engineering or business team.
• What imaging modes or payload architectures do you think are underused for Earth observation, and why?
• How would you decide whether a new EO/IR concept is worth a proof-of-concept investment?

Common mistakes to avoid

• Submitting a general systems engineering resume without EO/IR payload specifics. The role is payload-focused, not generic spacecraft systems.
• Claiming modeling or simulation experience without naming tools, methods, or the decisions your models supported.
• Ignoring the early-stage, cross-functional nature of the role. Candidates who only describe late-stage integration or single-team work miss the core of this job.
