Manufacturing Engineer II - Testbeds & EGSE

About the role

Muon seeks a Manufacturing Engineer to join our Testbeds & EGSE team — the group that builds the Hardware-In-The-Loop (HITL) testbeds behind every Muon mission and the electrical ground support equipment (EGSE) used to interface with our satellites during assembly, integration, and test. As this infrastructure scales across more missions, its repeatability lives or dies on documentation — and this role owns it: the procedures that make builds repeatable, and the knowledge base that makes the whole system understandable.

You'll bring an electrical or embedded software background strong enough to understand the systems you document — reading schematics and block diagrams, and following software-driven test flows. You'll stay close to the hardware: shadowing engineering builds, assisting on the floor, and iterating procedures side-by-side with the technicians who run them.

Due to the hands-on nature of this role, it requires onsite work at our San Jose location 5x days a week.

Responsibilities

• Own the team's procedure and work-instruction system, including templates, standards, and the release process
• Write new assembly, checkout, and maintenance procedures for testbeds and EGSE — shadowing engineering builds to capture steps at the source
• Keep existing procedures current as designs evolve, driving redlines and updates to closure
• Own the team's internal knowledge base: structure it, maintain it, and keep it authoritative
• Maintain testbed block diagrams and system documentation as configurations change across missions
• Own HITL maintenance communications: announcements, downtime coordination, and status updates to the teams that depend on testbed availability
• Assist and iterate on procedures with technicians on the floor until they're proven, and train the team on documentation standards
• Identify process and buildability improvements from build feedback, and channel design-for-assembly input back to the design engineers

Required Qualifications

• 5+ years of experience in manufacturing, test, or hardware engineering, with significant ownership of procedures, work instructions, or engineering documentation
• Electrical engineering or embedded software background, with the ability to read schematics, block diagrams, and software-driven test flows
• Excellent technical writing skills: clear, precise, and usable by someone other than the author
• Hands-on hardware fluency: comfortable at a bench with assemblies, harnesses, and basic test equipment
• Systematic and organized, with experience administering documentation, PLM, or knowledge-base tools
• Excellent communication and cross-functional coordination skills
• B.S. in an engineering discipline or equivalent hands-on experience

Nice-to-have Skills

• Experience in HITL, test lab, or production test environments
• Experience standing up documentation systems or templates from scratch
• Familiarity with knowledge-base and PLM platforms (e.g., Confluence, Duro, or similar)
• Scripting skills (Python or similar) for documentation automation or diagram generation
• Aerospace or other high-reliability industry experience
• Familiar with a Linux development environment

Salary

The salary range for this role is $159,000 - $178,000, 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.
