Quality Engineer - Mechanical

Quality Mechanical Engineer:

Lead Engineer, Mechanical and Structural Systems

Job Description

Position Overview

The Lead Engineer, Mechanical and Structural Systems is responsible for driving the design, fabrication, assembly, and field performance of mechanical and (BESS) battery energy storage systems. This role leads engineering execution across product development, factory build processes, and on‑site remediation activities. The ideal candidate combines deep technical expertise with hands‑on field capability, strong communication skills, and the ability to coach and develop junior engineers. This position ensures engineered solutions meet high standards for safety, quality, manufacturability, and reliability.

Requirements

Key Responsibilities

Mechanical & Structural Engineering

• Lead design and analysis of enclosure structures, including material selection, fasteners, hardware systems, load-path evaluation, environmental requirements, and integration with mechanical cooling and plumbing systems.
• Develop, validate, and release engineering documentation such as drawings, BOMs, specifications, and technical bulletins.
• Ensure designs meet regulatory, safety, structural, and internal quality standards while maintaining manufacturability and field-serviceability.

Fabrication & Assembly Processes

• Define tools, fixtures, and processes required for enclosure fabrication and assembly in factory environments.
• Partner with manufacturing teams to optimize assembly workflows, reduce quality escapes, and improve throughput.
• Support continuous improvement initiatives by refining fabrication sequences, mechanical installation practices, and structural integrity checks.

Field Remediation & On‑Site Support

• Serve as the lead technical authority for diagnosing mechanical, plumbing, or structural issues in the field.
• Execute or guide hands-on remediation using appropriate mechanical tools, repair methods, and verification techniques.
• Provide field teams with clear technical guidance, repair instructions, and root-cause analysis outputs.

Issues Triage:

• Serve as the front line for the quality intake systems and tasked with reducing ticket backlog and intake though the incorporation of lessons learned.
• Work to ensure tickets are properly assigned, prioritized, and evaluated for commercial risk.
• Use data analytics to review Non-Conformance Requests in the form of CAPAs, JIRAs, NCRs, and more.

Cooling & Plumbing Systems Integration

• Ensure enclosure systems properly interface with mechanical cooling equipment, HVAC connections, and required plumbing components.
• Oversee layout, routing, and installation methods for cooling lines, drains, and mechanical support systems.

Leadership, Mentorship & Communication

• Train and mentor junior mechanical and structural engineers in design fundamentals, engineering process discipline, and quality expectations.
• Communicate technical topics clearly to stakeholders at all levels, including operations leadership, project managers, manufacturing leads, and field technicians.
• Author detailed written procedures, technical bulletins, troubleshooting guides, and process documentation to support both factory and field operations.
• Foster a culture of innovation, accountability, and high-quality engineering output.

Qualifications

Required

• Bachelor’s degree in Mechanical Engineering, Structural Engineering, or related field.
• Extensive experience in mechanical system design, enclosure fabrication, or structural assemblies.
• Demonstrated hands-on capability with mechanical tools and field remediation.
• Strong understanding of mechanical cooling systems, plumbing interfaces, and industrial installation practices.
• Proven ability to lead engineering efforts and mentor junior engineers.
• Excellent verbal and written communication skills, including technical documentation.
• Ability to travel 25% or more

Preferred

• Experience in industrial manufacturing, energy storage systems, data centers, or similar enclosure-based systems.
• Familiarity with QA/QC processes, safety programs, and factory production practices.
• Proficiency in CAD tools and structural or thermal analysis software.

Success Profile

A successful Lead Engineer, Mechanical and Structural Systems is:

• Technically deep in mechanical and structural fundamentals.
• Hands-on, willing to travel and work in the field when necessary.
• Process-oriented, with strong documentation discipline.
• Innovative, always looking for better ways to build, assemble, repair, and design.
• A mentor and leader, capable of elevating the team’s engineering capability.
• A strong communicator, able to interface with executives, manufacturing leads, and technicians alike.
