Manufacturing Process Engineer (PCBA)

The Manufacturing Process Engineer (PCBA) will lead end-to-end development, implementation, and optimization of Adura’s high-reliability thermal PCB-A and integrated box-build manufacturing operations. This onsite role in Corona, CA is responsible for establishing process controls from SMT through box-build integration, supporting yield performance, and maintaining compliance for regulated markets.

Responsibilities

• Own full SMT line setup, including solder paste printing, 3D SPI control, reflow profiling (vacuum and nitrogen), AOI tuning, X-ray validation, and electrical test integration
• Optimize thermal PCB processes for heavy copper, metal-core, and high-current assemblies
• Develop process controls for Flying Probe electrical validation and functional testing
• Drive yield improvement through scrap reduction and cycle-time optimization
• Create and maintain PFMEA, control plans, and DOE initiatives, using SPC/CPK strategies to support stable process performance
• Design and implement scalable box-build manufacturing flow for complete electronic subsystems
• Develop mechanical assembly processes, including torque control, harness integration, connectorization, and enclosure assembly
• Establish ruggedization processes such as conformal coating, potting, sealing, and environmental protection
• Define functional test protocols for integrated subsystems
• Support NPI builds and process validation for new product introductions
• Evaluate and implement new equipment, tooling, automation, and production upgrades
• Oversee thermal profiling, stencil design, panelization optimization, and assembly fixturing
• Ensure material traceability and serialized tracking at the subsystem level
• Support and maintain ISO 9001 certification, collaborating with Quality on audits, corrective actions, and documentation control
• Drive readiness for AS9100 (Aerospace), IATF 16949 (Automotive), and ISO 13485 (Medical)
• Train and mentor operators and technicians on advanced manufacturing controls
• Support builds across aerospace control modules, defense electronics assemblies, industrial power systems, medical device subsystems, and high-performance lighting modules

Requirements

• 7+ years of experience in EMS / PCB-A manufacturing
• Extensive hands-on SMT setup experience, including SPI, AOI, reflow profiling, and X-ray validation
• Experience working in environments using Flying Probe or ICT testing
• Experience implementing or managing box-build and subsystem integration lines
• Strong knowledge of thermal PCB materials, heavy copper, and metal-core assemblies
• Experience in Aerospace, Defense, Automotive, Lighting, or Medical device environments
• Background in Lean, Six Sigma, SPC, PFMEA, and DOE
• BS in Electrical, Mechanical, or Manufacturing Engineering preferred

Compliance and Standards

• Ensure compliance with IPC Class 2/3 standards
• Support validated manufacturing processes suitable for regulated markets
