Process Engineer, PCB Assembly & Yield Improvement

Titan Circuits; Phoenix (AZ); On-site; USD 85,000 - 110,000; Full time

Job summary

Titan Circuits in Phoenix, AZ seeks a Process Engineer to develop, optimize, and sustain manufacturing processes for high‑mix PCB assembly, supporting SMT, reflow, AOI, selective solder, hand solder, mechanical assembly, and NPI builds.

The hands‑on, floor‑focused role will own yield performance, reduce escapes, and ensure documentation and process controls meet quality standards on the production line.

Qualifications

• 2–5+ years of process engineering experience in PCB assembly or electronics manufacturing.
• Hands‑on SMT, reflow profiling, AOI programming, or selective solder experience.
• Strong understanding of soldering fundamentals, IPC‑A‑610, J‑STD‑001, and general electronics manufacturing practices.
• Ability to read and interpret BOMs, assembly drawings, schematics, and datasheets.
• Proficiency with data analysis, SPC, and problem‑solving tools.

Responsibilities

• Develop, refine, and sustain manufacturing processes for SMT, reflow, selective solder, wave, hand solder, mechanical assembly, and conformal coating.
• Build stable process windows, define critical parameters, and enforce discipline around their use.
• Optimize equipment setup, changeover, programming, and material flow to improve throughput and reduce labor hours.
• Perform DOE, capability studies, and data‑driven problem‑solving to identify improvement opportunities.
• Create, modify, and maintain SMT programs (pick/place, fiducials, feeders, offsets).
• Develop accurate stencil aperture designs and drive proper stencil ordering.
• Profile ovens and maintain reflow parameters to meet solder quality requirements.
• Create and maintain AOI programs with correct calls, tolerances, and defect libraries.
• Support X‑ray inspection criteria and programming.
• Participate in early design reviews; identify DFM issues and alternatives.
• Validate BOMs, AVL requirements, tooling, fixtures, and build documentation before release.
• Drive complete NPI packages—routing, travelers, process sheets, reflow profiles, tooling—and support first‑article builds.
• Investigate defects, scrap patterns, and rework trends; implement permanent corrective actions.
• Support Quality on 8D, 5‑Why, and root‑cause activities.
• Train technicians, operators, and production staff on new processes and updates.
• Maintain controlled work instructions, setup guides, reflow profiles, SMT build sheets, and AOI specs.
