Business Line Manager

We are a Southern California contract manufacturer specializing in the joining of dissimilar materials via brazing. This is a hands‑on, highly technical role for an engineer who lives and breathes joining processes, someone who can serve as the resident subject matter expert on our floor, drive R&D projects from prototype through serial production and bring the depth of knowledge our work demands.

We are specifically seeking a candidate whose core expertise is in materials science and joining technologies, brazing first and foremost, with the credibility to lead, advise, and mentor on the production floor and in customer‑facing technical discussions.

• Serve as the on‑site subject matter expert for all brazing and dissimilar material joining operations
• Develop, document, and optimize brazing procedures for production and new program introduction
• Define filler metal selection, flux selection, atmosphere/temperature profiles, and fixturing approaches
• Troubleshoot joint failures, porosity, wetting issues, and thermal distortion; root cause to corrective action
• Maintain and expand internal brazing process knowledge base

• Lead new joining process development from feasibility through production readiness
• Define process qualification criteria and execute first article / process validation activities
• Drive PFMEA, control plans, and process documentation for new programs
• Partner with quality and operations to ensure processes are repeatable, measurable, and manufacturable at rate
• Identify and close gaps between prototype intent and production reality, early and often

• Review customer drawings and specifications for DFM and producibility relative to brazing and joining operations
• Identify and escalate tolerance stack‑ups, joint accessibility issues, and material incompatibilities at the quoting stage
• Communicate design intent clearly across engineering, quality, and production teams
• Mentor younger engineers on GD&T interpretation and the relationship between design intent and joining process outcomes

• Provide technical guidance to production floor teams on joining processes and quality standards
• Support customer technical reviews, PPAP activities, and supplier qualification efforts
• Contribute to continuous improvement initiatives tied to yield, throughput, and scrap reduction
• Help build and formalize the site's technical capability via documenting what has historically existed only as tribal knowledge

• 8–12 years of experience in materials joining engineering, with brazing as a primary area of expertise
• Demonstrated hands‑on experience with brazing of dissimilar material combinations (metals, ceramics, or composites)
• Deep understanding of filler metals, flux systems, atmosphere furnace brazing, and torch/induction brazing processes
• Proficiency in reading and interpreting engineering drawings per ASME Y14.5 (GD&T)
• Experience taking joining processes from prototype or R&D phase into repeatable serial production
• Strong root cause analysis and corrective action skills (you've diagnosed real joint failures under production pressure)
• Ability to communicate technical concepts clearly to non‑engineers, customers, and production personnel

• Experience with aerospace, defense, or high‑reliability manufacturing environments
• Familiarity with AMS, AWS, or MIL‑spec brazing standards
• Background with dissimilar metal combinations such as stainless‑to‑copper,…
