Senior Supplier Quality Engineer

About the role:

Mytra is seeking an Senior Supplier Quality Engineer to develop, qualify, and manage our electrical supply base from a quality perspective as we scale rapidly from prototype to volume production. This role will own supplier-facing quality end to end - from initial supplier qualification and manufacturing audits through ongoing performance management, corrective actions, and continuous improvement. You will work closely with Supply Chain, Engineering, and Manufacturing to ensure our suppliers can deliver repeatable, scalable quality across periods of aggressive growth. This is a hands-on, high-impact role requiring deep experience with electrical suppliers, strong judgment, and the ability to balance accountability with long-term supplier relationships.

Responsibilities:

• As a Supplier Quality Engineer, you’ll work closely with Supply Chain, Engineering, and Manufacturing to develop and manage a high-performing electrical supply base capable of delivering consistent, repeatable quality as Mytra scales. You’ll own supplier-facing quality from initial qualification through production ramp, partnering directly with suppliers to ensure their processes, systems, and facilities are built to support rapid growth.
• You’ll design and execute a robust supplier qualification and audit framework, assessing manufacturing readiness, quality management systems, process controls, and capacity to sustain quality through increasing volumes. You’ll spend time on-site at supplier facilities - domestically and internationally - leading audits, validating corrective actions, and developing suppliers over time.
• You’ll review and approve supplier quality documentation such as FAIs, PPAPs, PFMEAs, and Control Plans, ensuring inspection and test strategies are appropriate for both early production and scale.
• You’ll lead supplier issue resolution end to end, driving structured root cause analysis and corrective actions while holding suppliers accountable for performance. At the same time, you’ll adapt your approach based on supplier maturity and strategic importance, balancing firm expectations with collaborative problem-solving to maintain strong, productive relationships.

The Ideal Candidate:

• You’re very comfortable owning supplier quality end to end, from initial qualification and audits through production ramp and ongoing performance management.
• You’ve worked directly with electrical suppliers and understand the realities of manufacturing PCBAs, wire harnesses, PLCs, power electronics, cameras, sensors, and electromechanical assemblies.
• You’re excited to build a supplier quality system from the ground up, knowing it won’t be perfect on day one - and you enjoy iterating and improving it as the company scales.
• You’re comfortable influencing cross-functionally, partnering with Engineering, Supply Chain, and Manufacturing to align on risk, priorities, and tradeoffs.
• You’re familiar with core quality tools and when to apply them pragmatically: PFMEA, Control Plans, FAIs, PPAPs, SPC, 8D, and structured root cause analysis.
• You can assess whether a supplier is truly ready to scale - not just technically capable, but operationally and organizationally prepared for growth.

Preferred Qualifications:

• You’re comfortable spending time on factory floors, in supplier facilities, and on video calls digging into real problems.
• Ambiguity doesn’t scare you; you’re willing to make decisions with imperfect information, recognize when something isn’t working, and pivot quickly.
• You can clearly communicate quality risks, findings, and recommendations to a wide range of audiences, from operators to senior leadership.
• You’ve led on-site supplier audits and developed corrective action plans that actually improved manufacturing outcomes.
• You’ve qualified new suppliers or manufacturing lines and supported them through early builds and volume ramps.
• You understand common failure modes in electrical assemblies and know how to design inspection and test strategies to catch issues early.
• You’ve built lightweight but effective quality processes that scale, rather than heavyweight systems that slow teams down.

A Final Note:

You’re encouraged to apply even if you can’t take on every example project in its totality. We work closely and collaboratively at Mytra - No one takes on projects alone. We seek people who are eager to work together, learn new things, and bring unique perspectives.
