# Jed Hortaleza > Manufacturing & Process Tech | Additive Mfg · Battery Cell Production · Cleanroom Ops | Bay Area Location: San Francisco Bay Area, United States Profile: https://flows.cv/jedhortaleza Senior Manufacturing Technician with 4+ years of experience at companies like Carbon and Tesla — two of the Bay Area's most demanding production environments, plus 4+ additional years across operations, logistics, and tech roles. At Carbon, I own Teflon coating operations and first-pass yield tracking (85%+ weekly targets), have led cleanroom 5S optimization and tool substitution initiatives, and designed fixtures that made it into official work instructions. At Tesla, I contributed to 40,000+ battery cells per shift on the 4680 line and earned a top-3 PPM ranking. I bring a continuous improvement mindset to everything I touch — if a process can be leaner, a fixture better designed, or a work instruction clearer, I'll find it and fix it.
