Senior Manufacturing Engineer

Senra Systems•Redondo Beach, CA

7d•$125,000 - $160,000•Onsite

About The Position

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 seeking a Senior Manufacturing Engineer to take ownership of complex wire harness programs across our customer portfolio. You’ll develop engineering packages including detailed work instructions and formboards, drive process improvements and serve as the technical point of contact for assigned programs, working closely with production, quality and customers to deliver. You’ll own programs end-to-end – managing customer relationships, solving complex technical challenges, developing build processes, and ensuring quality and delivery targets are met. You need to be self-sufficient, technically deep, and comfortable operating with minimal direction. This role reports to the Lead Manufacturing Engineer but operates with significant independence day-to-day.

Requirements

Bachelor's degree in engineering, STEM-related field, or 8+ years of directly related hands-on manufacturing experience
5+ years of manufacturing engineering experience in fast-paced production environments (wire harness, electrical assembly, or similar)
Proven ability to work independently with minimal supervision in a high-accountability role
Strong customer-facing skills with ability to manage technical relationships and communicate effectively
Proficiency in CAD tools for creating assembly drawings and tooling designs
Deep understanding of manufacturing principles: material workflow optimization, PFMEA, 5S, lean manufacturing, time studies, capacity planning
Expert ability to evaluate parts and processes, determining optimal assembly approaches quickly
Self-motivated problem-solver who thrives on autonomy and takes ownership of outcomes
Excellent project management skills with ability to juggle multiple programs and priorities

Nice To Haves

Certification or extensive experience with IPC-620 or NASA STD 8739.4 standards
Deep expertise in aerospace and defense wire harness best practices and quality standards
Experience at a contract manufacturing company managing multiple customer programs simultaneously
Hands-on background with complex harness fabrication, box builds, connector mates, and electrical testing — used to inform engineering decisions, not as a primary job function
Experience leading process improvement initiatives (Six Sigma, Kaizen) with documented efficiency gains
10+ years of overall manufacturing engineering experience with progressive responsibility
Background with MES or ERP systems
Supply chain coordination experience

Responsibilities

Lead planning and coordination of complex harness builds by developing comprehensive work instructions, formboards, and tooling solutions
Establish manufacturing standards and processes that enable production to build efficiently and autonomously
Drive improvements to quality, efficiency, and throughput through process benchmarking and workflow optimization
Evaluate new parts and processes, determining optimal paths for assembly and scalability
Commission new equipment, qualify processes, and optimize production flow as needed
Partner with the production team on technical issues that require engineering disposition, providing structured solutions rather than ad hoc floor support
Work with the production team to surface systemic issues, translating recurring blockers into process improvements and engineering solutions
Collaborate with the software team on digital solutions to improve traceability, workflow, and reporting
Maintain 5S, lean manufacturing principles, and adherence to aerospace quality standards
Develop and maintain engineering documentation that keeps assigned programs aligned with IPC-620/NASA 8739.4 and customer-specific requirements
Serve as the primary technical liaison between production and assigned customers
Manage complex technical inquiries, resolve escalated issues, and ensure adherence to stringent specifications
Collaborate with the Program Management Team on program reviews and customer communications, providing technical depth and engineering rationale as needed
Coordinate cross-functionally with production, quality, and supply chain to maintain program momentum and resolve blockers
