About the role

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 four days per week.

Responsibilities

Comms, Simulation and Test

• 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.

Required Qualifications

• 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.

Nice-to-have Skills

• 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.

Salary

The salary range for this role is $190,000-$210,000, 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.
