INFINITUM ELECTRIC

Senior Supplier Quality Engineer

Job Description

POSITION OVERVIEW

COMPANY OVERVIEW

Infinitum Electric is a technology company pioneering the next generation of axial flux electric motors — lighter, more efficient, and more sustainable than conventional motor designs. Our supply chain spans contract manufacturers, magnet suppliers, PCB manufacturers, and precision machining partners across the US, Mexico, and Asia. As we scale rapidly in revenue, the quality of our supply base is directly linked to our ability to deliver reliable, world-class products to our customers.

POSITION SUMMARY

The Senior Supplier Quality Engineer is responsible for developing, managing, and continuously improving the quality performance of Infinitum's supplier base — with particular focus on critical and high-risk suppliers. This role leads supplier qualification, audit programs, incoming quality controls, supplier corrective action management, and collaborative supplier development activities. The Senior SQE acts as both a quality gate and a lean development partner for Infinitum's supply chain — ensuring that supplier capability grows in step with Infinitum's product quality demands.

KEY RESPONSIBILITIES

Supplier Quality Management & Performance

Own the quality performance of assigned suppliers — tracking incoming defect rate (PPM), on-time delivery, corrective action closure rate, and audit findings across a defined supplier portfolio

Maintain supplier scorecards and lead periodic supplier quality review meetings — driving accountability and continuous improvement in supplier performance

Establish and enforce incoming inspection plans, acceptance criteria, and control plans for critical components including magnets, PCBs, stator assemblies, and precision machined parts

Manage supplier quality escapes — initiating containment, leading or coordinating root cause investigation, and driving permanent corrective action through verified closure

Monitor supplier quality trends and proactively escalate systemic risks before they affect production or customers

Supplier Qualification & Development

Lead new supplier qualification activities including quality system assessments, process audits, first article inspection (FAI), and approval decisions

Conduct on-site supplier audits — process audits, system audits, and layered process audits — at domestic and international supplier locations

Develop supplier lean and quality capability through joint improvement activities — including Kaizen Events, VSM exercises, A3 problem solving, and SMED workshops conducted at supplier facilities

Work with suppliers to implement pull systems, visual management, standard work, and statistical process control where deficiency has been identified

Assess and develop Tier 2 supplier quality capability in coordination with Tier 1 strategic partners

Incoming Quality Control

Design and maintain incoming inspection sampling plans based on supplier risk level, historical performance, and component criticality

Work with receiving and production teams to ensure incoming material is properly identified, inspected, and dispositioned — with clear quarantine and hold processes for nonconforming material

Drive suppliers toward certified supplier status (skip-lot or ship-to-stock) as their quality performance matures and data supports reduced incoming inspection

Manage nonconforming material disposition including use-as-is decisions, rework, return to supplier, and scrap — with appropriate engineering review and documentation

Supplier Corrective Action (SCAR) Management

Issue Supplier Corrective Action Requests (SCARs) for quality escapes, audit findings, and systemic performance issues — with clear problem statements, root cause requirements, and response timelines

Review and approve supplier 8D corrective action responses challenging superficial root cause analysis and requiring systemic corrective actions, not symptom-level fixes

Track open SCARs through to verified effectiveness — not closing actions until sustained improvement is demonstrated with data

Analyze SCAR trends to identify recurring failure modes, systemic supplier weaknesses, and opportunities for proactive intervention

Cross-Functional Collaboration & Quality Systems

Partner with engineering, operations, and supply chain teams on new product introductions to ensure supplier quality requirements are defined, communicated, and controlled from the earliest design stages

Contribute to FMEA development and control plan creation for components sourced from the supply base

Support the Infinitum Quality Management System (QMS) by maintaining supplier quality records, audit reports, and qualification documentation in compliance with applicable standards

Represent supplier quality in design reviews, engineering change notifications (ECNs), and material review board (MRB) activities

Participate in the development and improvement of supplier quality procedures, work instructions, and supplier quality manual requirements

REQUIRED QUALIFICATIONS

Bachelor's degree in Mechanical Engineering, Electrical Engineering, Industrial Engineering, Materials Science, or a related technical field

5–8 years of experience in supplier quality engineering in a manufacturing environment — with demonstrated experience managing supplier relationships, conducting audits, and driving corrective actions

Hands-on experience conducting supplier process audits and quality system assessments

Proficiency with core quality tools: FMEA, control plans, MSA/Gage R&R, SPC, 8D, 5 Whys, and Ishikawa

Experience with first article inspection (FAI) processes and incoming inspection plan…
