Muon Space, a LEO satellite constellation company founded in 2021, is seeking a Senior People Business Partner to drive people strategy and execution across the organization. This is a full-stack role combining strategic systems-level thinking with hands-on operational execution.
You will report to the VP of People Operations and operate with high autonomy as a trusted advisor to departmental leaders and managers. Key responsibilities include:
**Strategic Architecture & Operational Execution**
Architect and implement critical People Ops initiatives—from new manager training to talent review cycles—from initial design through final launch. Continuously evaluate workflows to eliminate operational friction across a distributed workforce, building scalable solutions that enable growth and mitigate organizational risks.
**Manager Development & Coaching**
Partner directly with directors and frontline managers to build manager capability, serving as a warm, grounded coach on leadership best practices. Design and deliver structured manager development programs that equip leaders to manage high-performing teams, navigate complex performance management, and deliver constructive feedback. Guide and upskill managers on policy execution through clear, accessible documentation and hands-on guidance.
**Autonomous Problem Solving & Employee Relations**
Identify, diagnose, and resolve company culture vulnerabilities and complex personnel challenges before they impact the business. Handle complex employee relations, performance discussions, and sensitive workforce issues with extreme discretion, empathy, and integrity. Use analytical judgment and contextual reasoning to solve ambiguous problems where precedent may be limited.
**Culture & Operational Excellence**
Serve as a visible anchor for Muon's values, fostering a workplace culture anchored in continuous growth, feedback, warmth, and mutual respect. Provide a helpful, empathetic, and approachable point of partnership for employees at every level.
The position is hybrid, requiring on-site presence in San Jose three days per week, with potential flexibility for exceptional West Coast-based candidates who can travel to the Bay Area quarterly.
**Requirements**
- 6–10+ years of progressive HRBP or People Operations experience in fast-paced environments, with proven track record of full-stack ownership (both strategic design and tactical implementation)
- Demonstrated success designing, facilitating, and driving manager development initiatives and coaching leadership cohorts
- Proven ability to translate broad business goals into actionable project roadmaps and execute independently with minimal direction
- Outstanding verbal and written communication skills with natural approachability, high emotional intelligence, warmth, and customer-service mindset
- Exceptional judgment when navigating ambiguous employee relations matters, maintaining absolute confidentiality and security around sensitive personnel data
- Hands-on experience architecting and managing modern HR systems (Rippling, Lattice) and building out accessible and clear documentation (Google Workspace, Confluence)
- ITAR/EAR compliance: Must be a U.S. person (citizen, national, lawful permanent resident, refugee, or asylee) or eligible to access export-controlled information
