Job Summary

Details:

Our client designs and manufactures intelligent energy storage systems for commercial buildings supporting more efficient use of traditional and renewable power. Their engineering team develops modular battery technology for dense environments where safety reliability and performance matter.

We are hiring a hands-on Mechanical Engineer to design and deliver next-generation Battery Energy Storage Systems (BESS). This role owns mechanical development from concept through production and works across electrical product and manufacturing teams to deliver scalable production-ready hardware.

Success requires strong engineering judgment ownership and the ability to translate concepts into manufacturable designs within a fast-moving product environment.

Responsibilities

Design mechanical components and assemblies in CAD including system packaging for PCBs batteries sensors switches fuses lighting and associated wiring
Drive cross-functional collaboration between mechanical electrical and product teams to improve system design manufacturability and cost
Perform component- and assembly-level analysis and verification to meet performance safety reliability and cost requirements
Own the engineering bill of materials (EBOM) through development and transition to the manufacturing BOM (MBOM) for production release
Collaborate closely with internal and external manufacturing partners to optimize designs for manufacturability assembly and scalability
Engage directly with global suppliers and partners during design validation and product launch phases
Define scopes of work and technical requirements to maintain alignment with external vendors
Manage design documentation revisions and release processes within the PLM system
Support hardware integration prototype development root cause analysis and design iteration
Contribute across projects and priorities to support overall product execution

Details:

Basic Qualifications

Bachelors degree in Mechanical Engineering or a closely related field.
Minimum 5 years of experience designing and manufacturing mechanical systems using processes such as sheet metal forming injection molding and CNC machining.
Strong 3D and 2D CAD skills including GD&T to ASME Y14.5 and worst-case tolerance analysis.
Demonstrated ownership of mechanical assemblies from architecture and design through production release.
Solid understanding of mechanical enclosures structures and mechanisms integrated with electrical systems.
Proven ability to translate abstract concepts into prototypes proof-of-concepts and production-ready designs.
Working knowledge of DFMEA and PFMEA methodologies.
Basic understanding of battery safety considerations related to handling storage assembly and operation.
Strong communication and collaboration skills with the ability to work independently and drive results across teams.

Preferred Qualifications

Familiarity with product certification processes (e.g. UL CE CSA).
Experience with stationary BESS industrial switchgear or similar electromechanical systems.
Experience managing multiple product SKUs and design baselines within a PLM system.
Experience with structural and thermal analysis tools and methods.
Background in customer-facing industries such as consumer electronics or automotive.

Additional Requirements

This role is based in Irvine CA or New York NY and requires being onsite.
Minimal travel may be required to support company operations.

Salary Range:

Irvine CA: $120000 to $145000 base
New York NY: $130000 to $155000 base
