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
