Quality Engineer, Switchboards & AI

What you’ll do

Giga Energy builds mission-critical power and cooling infrastructure for AI datacenters — chillers, e-houses, switchgear, and fully integrated AI pods delivered to hyperscaler and utility customers across North America. As Quality Engineer, you will be the hands-on quality owner for our newest and most complex product lines — the AI-specific equipment that's driving Giga's next phase of growth. You'll run incoming, in-process, and final inspection for these components, chase down supplier quality issues, and be the person who catches a defect before it ships. This is a technical, in-the-weeds role: less about building the quality org from scratch and more about being excellent at the day-to-day execution that keeps AI pod quality airtight as volume ramps.

Where you’ll work

We are an in-office culture — velocity matters when you're building physical infrastructure, and the best decisions happen in the room. This role is based in our Long Beach, CA office, with full-time onsite expectations.

Responsibilities

Quality System Execution

• Execute quality procedures and work instructions for AI pod components (chillers, e-houses, switchgear) in alignment with the site's ISO 9001 QMS
• Support internal and external audits, including ISO certification efforts, for AI product lines
• Maintain the product compliance matrix mapping chillers, e-houses, switchgear, and AI pods to applicable UL, NEC, NEMA, and customer-specific requirements
• Interface with UL Compliance Officers and third-party agencies during audits for AI equipment

Supplier Quality — China, Mexico & India

• Support supplier qualification, periodic re-qualification audits, and scorecard reviews for AI component suppliers
• Execute Supplier Quality Agreements (SQAs) covering material certifications, First Article Inspection (FAI), critical specs, and dimensional tolerances
• Issue Supplier Corrective Action Requests (SCARs) and drive to closure using 8D methodology; investigate root cause on repeat escapes
• Support pre-shipment inspection checkpoints at overseas CM facilities to prevent quality escapes from reaching Giga facilities
• Verify incoming materials meet specifications — manage PPAP-equivalent documentation (material certs, CoC, test reports)

Incoming, In-Process & Final Inspection

• Execute the incoming quality control (IQC) process for chillers, e-houses, and switchgear components — AQL-based sampling plans, accept/reject criteria, and non-conforming material (NCM) disposition
• Build and maintain inspection checklists for critical AI pod components: bus bars, breakers, CTs, SPDs, chiller assemblies, and e-house structural/electrical elements
• Execute in-process quality control plans (QCPs) and visual work instructions (VWIs) for safety-critical assembly operations — bus bar torquing, wiring termination, CT secondary connections
• Perform final outgoing inspection and electrical test protocol: insulation resistance, continuity, CT polarity, and breaker functional tests — 100% on every unit
• Maintain serialized test records and Certificate of Conformance (CoC) for every AI pod shipment
• Execute routine, type, and special test protocols for chillers, e-houses, switchgear, and integrated AI pods

Continuous Improvement

• Lead root cause analysis using structured tools — 8D, Fishbone, 5-Why — for internal non-conformances and field failures on AI product lines
• Collaborate with manufacturing engineers on Lean/Six Sigma initiatives to reduce defects, scrap, and rework
• Track and report quality KPIs for AI components: incoming PPM, first-pass yield (FPY), scrap and rework rate, and warranty claim rate
• Support digital systems used to capture, track, and resolve NCRs, SCARs, and customer complaints; maintain the calibration register for gauges and test equipment used on AI lines

Customer & Compliance

• Support the customer complaint process for AI product lines — intake, on-site investigation, 8D report, and formal closure within SLA (containment within 24 hours, full 8D within 30 days)
• Support warranty claim investigation; represent Quality at customer sites during field investigations and commissioning inspections for AI pods
• Ensure compliance with applicable safety and environmental regulations
• Support interfacing with customers and regulatory agencies during audits, UL inspections, and project quality reviews

Requirements

• Degree in Mechanical, Electrical, Industrial Engineering, or a related technical field
• 3+ years of experience in quality engineering in electrical, power, cooling, or industrial manufacturing
• Solid understanding of UL 891/67 compliance or equivalent LV switchgear/panelboard standards
• Experience with supplier quality processes in an international CM environment — audits, corrective actions, and FAI documentation
• Proficiency in IQC sampling methodology and incoming inspection practices
• Hands-on experience with PFMEA, control plans, and visual work instructions
• Strong root cause analysis skills — 8D, Fishbone, 5-Why
• Strong communicator — able to write clear technical reports and interface with cross-functional teams
• Ability to collaborate effectively with cross-border engineering and production teams (China, Mexico, India, US)

Bonus points 

• ASQ Certified Quality Engineer (CQE), Six Sigma Green Belt, or equivalent certification
• Experience with cooling systems (chillers) or modular/prefabricated electrical enclosures (e-houses)
• Experience using digital quality tools — ERP quality modules — to track NCRs, SCARs, and KPIs
