Medical Kit Assembly Jobs in California (NOW HIRING)

At Senra Systems, we believe that the future of manufacturing lies not in automation, but in configuration.  

We supercharge electrical wire harness manufacturing through software configuration, transforming skilled assembly tasks into high-throughput production lines. We enable customers to design what they want, when they want it and deliver harness builds at record-breaking speed.

We're building a dedicated Production Engineering function at Senra Systems – a team that owns the floor, not the desk. As a Production Engineer, you will be embedded in manufacturing as the technical resource our assembly technicians rely on during active production. While Manufacturing Engineers own the front-end documentation – BOMs, Engineering Masters, work instructions, and formboards – you own execution. 

You'll troubleshoot builds in real time, support first articles, verify cable and component kits, disposition non-conformances, and serve as the day-to-day engineering presence that keeps production moving. This role reports to the Lead Production Engineer and works closely with the Manufacturing Engineering, Production and Quality teams. 

What you'll own:

Floor Troubleshooting & Real-Time Support 

• Serve as the on-floor technical resource during active production – resolving assembly issues, documentation discrepancies, and build questions without halting throughput 
• Identify and escalate systemic issues to the Lead PE or ME team with clear, structured documentation 
• Participate in root cause analysis and corrective action implementation for recurring production issues 

NCR Disposition 

• Review and disposition non-conformances generated on the floor with documented rationale (use-as-is, rework, or scrap) 
• Maintain NCR aging within SLA; escalate items that require engineering disposition beyond your scope 
• Coordinate with Quality on in-process inspection holds and final disposition sign-off 

First Article & First Build Support 

• Provide hands-on engineering support during first articles and new part number introductions 
• Walk the floor during first builds, verify documentation accuracy, and identify gaps before they become production issues 
• Capture redlines and documentation feedback and submit to the ME team in a structured, timely manner 

Kit Verification & Material Flow 

• Audit incoming cable and component kits against the build package before they reach the floor  
• Flag shortages, substitutions, or discrepancies and coordinate resolution with kitting, supply chain and engineering  

Technician Support & Mentorship 

• Answer technical questions from assembly technicians on wire prep, crimping, connector insertion, splicing, and harness routing 
• Coach to IPC/WHMA-A-620 and NASA 8739.4 workmanship standards; recognize and address non-conforming work at the source 
• Contribute to a culture of quality ownership on the floor – every technician should know what good looks like 

What you'll bring to the team:

Required: 

• 1–3 years of hands-on experience in wire harness or cable assembly manufacturing 
• Working knowledge of wire harness assembly processes: wire prep, crimping, soldering, connector insertion, and harness routing 
• Familiarity with IPC/WHMA-A-620 workmanship standards 
• Ability to read and interpret wiring diagrams, schematics, assembly drawings, and work instructions 
• Strong attention to detail and a quality-first mindset 
• Must be a U.S. Person (U.S. Citizen or Lawful Permanent Resident)  

Preferred: 

• Prior experience as a manufacturing, build or sustaining engineer  
• Extensive technical authoring experience i.e. developing engineering masters, dispositioning non conformances, etc.  
• High degree of ownership, self-starting and proactive with a bias toward action and solutions  
• Experience in an aerospace or defense manufacturing environment 
• Exposure to NASA 8739.4 workmanship requirements 
• Familiarity with MIL-spec connectors and contacts (D-sub, LEMO, Glenair, Amphenol, etc.) 
• IPC/WHMA-A-620 CIS or CIT certification 
• Experience with NCR or nonconformance management workflows 

Success in This Role Looks Like: 

Within 3–6 months, you will have: 

• Become a trusted technical resource on the floor – technicians know to come to you first 
• Achieved consistent NCR disposition turnaround within SLA with clear, documented rationale 
• Supported at least one full first article cycle from kit verification through build completion and redline capture 
• Demonstrated a consistent quality-first approach that has visibly reduced rework or build stops on your assigned product families 

Compensation:  

• Compensation will be based on experience, qualifications, and other job-related factors.  
• Salary Range: $75,000-$85,000 
• This is an onsite role at our factory in Cypress, CA.
