Assistant Process Engineer Jobs in Arizona (NOW HIRING)

The Process Engineer is responsible for developing, improving, and sustaining manufacturing processes across Titan Circuits' high-mix PCB assembly environment. This role supports SMT, reflow, AOI/X-ray, selective solder, hand solder, mechanical assembly, and NPI builds by ensuring processes are stable, repeatable, documented, and capable of delivering high yields with minimal rework.

This is a hands-on, floor-focused engineering role-Titan expects the Process Engineer to be visible on the production line, solving issues in real time, tightening process controls, and owning yield performance and escape reduction within their area.

• 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 chronic defects, scrap patterns, and rework trends; implement permanent corrective actions.

• Support Quality on 8D, 5-Why, and root-cause activities.

• Work cross-functionally with Quality, Production, and Engineering to resolve issues quickly.

• Ensure parameters and documentation match AS9100 requirements-no undocumented shop-floor changes.

• Maintain accurate, controlled work instructions, setup guides, reflow profiles, SMT build sheets, and AOI specs.

• Train technicians, operators, and production staff on new processes and updates.

• Ensure all process documentation remains synchronized with current revision levels.

• Support preventive maintenance standards for process equipment.

• Assist in identifying and justifying capital equipment improvements.

• Design or source tooling, fixtures, and work aids as needed.

• 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 technical documents: BOMs, assembly drawings, schematics, and datasheets.

• Proficiency with data analysis, SPC, and problem-solving tools.

• High-mix, low/medium-volume PCB assembly environment.

• Aerospace/defense manufacturing or AS9100 familiarity.

• Experience with DOE, capability studies, or statistical analysis tools.

• Experience with fixture/tooling design (3D CAD skills a plus).

• ERP experience (Cetec preferred).

• Floor-first mentality: Visible, responsive, and deeply engaged with production.

• Technical depth: Understands why processes work-not just how.

• Data-driven: Uses measured evidence to drive decisions and validate improvements.

• Documentation discipline: No undocumented changes or tribal knowledge workflows.

• Urgency: Moves fast when quality or production flow is at risk.

• Problem-solving depth: Fixes root causes-doesn't patch symptoms.

• Clear communicator: Direct, concise, and factual in updates and escalations.

• Ownership mindset: Treats yield and escapes as personal responsibilities.

• Extensive time on the production floor in SMT, soldering, and assembly areas.

• Occasional lifting of tooling, fixtures, or equipment components (~25 lbs).

• Work in ESD-controlled environments with relevant PPE.
