Senior Mechanical Engineer

The Senior Mechanical Engineer reports currently to the Vice President, Product Development Engineering . This individual is responsible for the design, development, and validation of mechanical subsystems used in energy storage systems for electrical grid and commercial applications. This role requires cross-functional collaboration to ensure the safety, efficiency, and manufacturability of designs throughout the product lifecycle.

This is a critical role within the engineering team, directly impacting product development, reliability, and scalability. The Senior Mechanical Engineer works closely with manufacturing to ensure designs are not only high-performing and cost-effective but also efficient to produce the worlds best battery energy storage systems.

Responsibilities:

Design & Development

o Perform requirement analysis, design architecture, worst-case calculations, DFMEAs, and design reviews (Failure Mode & Test Results).

o Develop thermal management systems of enclosures; Design of large steel enclosures and assemblies; Develop pieces and parts for plastic injection molding, die casting, sheet metal, weldments, machined components, HVAC piping.

o Design packaged electronics/equipment, auxiliary power systems, safety monitoring and control systems, and electrical bus components (high, medium, and low voltage).

o Develop and execute design verification plans and create necessary engineering documentation (CAD models, drawings, simulations, BoMs, reports).

o With assistance from others, ensure compliance with IEEE, NEC, NFPA, UL, and other regulatory standards for grid utility applications.

o With assistance from others, evaluate, design, and select electrical distribution components (busbars, high power cables).

Technical Collaboration & Leadership

o Work closely with manufacturing teams to ensure efficient production of designs including DFA/DFM/DFS process.

o Research new technologies to improve safety, performance, efficiency, and cost effectiveness.

o Mentor and develop junior engineers, sharing technical expertise across teams.

o Supervise and direct supporting resources (contractors, suppliers, third parties).

o Cross-Disciplinary Problem-Solving, acting as a bridge between engineering, operations, and production teams.

Compliance & Documentation

o Adhere to federal and state regulations.

o Adhere to all company policies, processes, and procedures.

o Performs other duties as requested, directed, or assigned. Predictable and reliable attendance.

Position Qualifications:

Bachelors degree in mechanical or systems engineering, or equivalent field.

Minimum of five (5) years experience designing electromechanical components for medium/high-voltage switchgear or large data centers.

Expertise in packaging large cooling, electrical/electromechanical systems, electrical distribution components (contactors, fuses, busbars), and power conversion systems.

Strong foundation in mechanics of materials, fluids, thermodynamics, and heat transfer.

Proficiency in 3D CAD (SolidWorks, PDM) and engineering analysis tools (FEA, CFD, statistics).

Experience designing for safety and regulatory compliance (IEEE, NEC, UL, IEC or similar).

Strong technical communication skills for presenting test data and working with suppliers.

Self-motivated problem solver with strong attention to detail.

Experience with motor drives, UPS, solar PV, switchgear, and other high-power electrical equipment preferred.

Ability to travel domestically and internationally, up to 15%.

Key Competencies:

Decision Making & Analysis: Makes sound decisions based upon a mixture of data-driven analysis, expertise, experience, and judgment; collects relevant information, seeks input from others, and identifies connections and/or root causes of problems.

Continual Improvement: Displays a consistent orientation toward producing the highest quality products or services, while keeping a focus on sustainability. Constantly looking for incremental improvements in work processes and results.

Takes Initiative: Exhibits strong drive for results and success; conveys a sense of urgency and drives issues to closure; persists despite obstacles and opposition.

Delivers Results: Achievement-oriented, feeling a sense of urgency to reach goals on time, if not before.
