Senior Manufacturing Engineer

Senra Systems•Redondo Beach, CA

21h•$125,000 - $165,000•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 an exceptional Senior Manufacturing Engineer to serve as the engineering lead at our Redondo Beach facility. This is a high-autonomy role where you'll be the sole engineering presence on site, responsible for keeping production running smoothly while the core engineering team focuses on ramping our expanded Cypress facility. You'll own the complete engineering function for Redondo - managing customer programs, solving complex technical challenges, developing build processes, and ensuring quality and delivery targets are met. You need to be self-sufficient, customer-savvy, and technically strong enough to handle anything that comes your way without constant support from the broader team. This role reports to the Manufacturing Engineering Manager 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
