Product Manager II - Software & Communications

Muon Space is hiring a Product Manager to own how much data our missions get to the ground, and how we prove it. Reporting to a Director of Product Management, you will own bits-to-ground communications across RF and optical links, simulation, and software test. 

This position is hybrid and requires working on-site in our San Jose, CA office three days per week.

• Own the product roadmap for bits-to-ground communications across RF and optical (OCT) links.
• Own the product roadmap for Muon Sim, the digital twin behind mission design and mission operations, including the throughput analysis that sets what a constellation can deliver.
• Grow simulation into a tool for software iteration, so flight and ground software can be exercised against the twin before it reaches a spacecraft.
• Own the product roadmap for software test infrastructure, automation, and hardware-in-the-loop environments.
• Define and prioritize features that improve product quality, schedule adherence, or customer value.
• Author clear Product Requirements Documents (PRDs), drive alignment, and follow through reliably.
• Partner with the Director of Product Management to develop the strategy for the product areas including build/buy decisions.
• Conduct customer interviews, gather feedback on product–market fit, and translate insights into roadmap decisions.

Cross-functional Coordination

• Partner closely with engineering teams across ground software, simulation, test, and mission systems to define features and roadmap.
• Partner with other software product managers on roadmaps where capabilities intersect.
• Coordinate with the Director of PM — Federal on defense-aligned product needs and inputs to roadmap.
• Collaborate with the VP of Product and the broader PM team on strategic roadmap decisions and prioritization trade-offs.

• 3–5 years of Product Management experience, with demonstrated success owning software products in technically complex environments.
• Experience in communications systems, simulation, test infrastructure, or adjacent deep-tech software domains.
• Experience working cross-functionally with multiple engineering teams at once, rather than a single team.
• Demonstrated success in uncertain environments with incomplete requirements and shifting schedules.
• Proven track record delivering major features or programs spanning multiple months of effort.
• History of independent execution and implementation across multiple concurrent workstreams.
• Strong fluency working with engineering peers and leadership; able to influence cross-organizational technical investment without direct authority.
• Demonstrated ability to translate customer mission needs into detailed product requirements and acceptance criteria across software systems.
• Bachelor's degree in Engineering, Computer Science, or a related technical field; advanced degree preferred.

This position requires access to export controlled information. To conform to U.S. Government export regulations applicable to that information, applicant must either be (A) a U.S. person, defined as a (i) U.S. citizen or national, (ii) U.S. lawful, permanent resident (green card holder), (iii) refugee under 8 U.S.C. § 1157, or (iv) asylee under 8 U.S.C. § 1158, (B) eligible to access the export controlled information without a required export authorization, or (C) eligible and reasonably likely to obtain the required export authorization from the applicable U.S. government agency. The Company may, for legitimate business reasons, decline to pursue any export licensing process.

• Active U.S. Government security clearance.
• Familiarity with RF or optical communications, link budgets, or ground station networks.
• Familiarity with mission design, constellation modeling, or digital-twin platforms across orbit, power, and data delivery.
• Familiarity with test automation or hardware-in-the-loop test environments.
• Familiarity with building or operating software for the space environment.
• Prior experience in startup or high-growth technology environments.

The salary range for this role is $177,000 - $203,000, 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.
