About the Role - Manufacturing Quality Engineer

Peak Energy is looking for a Manufacturing Quality Engineer to establish and lead quality engineering at Peak Energy from the ground up. The Manufacturing Quality Engineer will be responsible for establishing foundational quality systems, driving PFMEA and in-process quality controls, and managing supplier and incoming component quality. They will work closely with engineering, operations, and leadership to define the standards and processes that ensure our battery systems are safe, reliable, and ready for customer deployment.

What You'll Do (Responsibilities)

Conduct rapid assessments of current build processes, failure modes, and risk areas, identifying the highest-priority gaps in quality and safety coverage.

Own and continuously improve the PFMEA process with cross functional review and approval.

Establish an IQC framework, develop supplier qualification criteria, and begin laying the groundwork and systems for supplier quality.

Collaborate closely with design and engineering to surface high-risk product failure modes early, bringing quality thinking into design reviews before issues become build problems.

Define control, verification, and sampling plans to ensure part quality meets requirements in both development and on-going production.

Define and track key quality metrics; drive corrective and preventive action (CAPA) processes.

Advocate for quality in a fast-paced, production-driven environment.

Build the quality organization as the company scales.

Drive field investigations and customer-facing quality responses.

What You'll Bring (Qualifications):

5+ years of quality engineering experience, ideally in battery, EV, power electronics, or adjacent hardware manufacturing.

Hands-on experience running or contributing to PFMEA processes, with strong working knowledge of RPN prioritization and risk mitigation strategies.

Experience establishing quality systems in an early-stage or resource-constrained environment.

Familiarity with battery-specific failure modes (cell-level, pack-level, thermal, BMS-related).

Experience leading field failure investigations, including root cause analysis, cross-functional problem solving, and solution implementation.

Working knowledge of IQC processes and supplier quality management.

Strong communication skills and the ability to influence without authority and navigate tradeoffs between quality and speed.

Eligible to work in the U.S.

Preferred Qualifications:

Experience shipping a product from prototype phase through to customer deployment.

Exposure to relevant standards (ISO 9001, IATF 16949, UL, IEC 62133, UN 38.3).

Familiarity with safety risk assessment frameworks for battery production environments.

Experience building and leading a quality team.
