• Collaborate with internal product design and quality teams to validate findings and implement fixes.
• Deliver structured, accurate reporting that supports continuous product improvement.

System Knowledge & Field Collaboration

• Develop deep understanding of containerized energy storage systems, including fire suppression, HVAC, and thermal management.
• Support troubleshooting when container-level systems affect battery operations.
• Interface with engineering, operations, and field technicians to ensure consistent and effective support.
• Provide design feedback to improve system reliability and maintainability.

Documentation & Continuous Improvement

• Maintain detailed service documentation, analysis results, and lessons learned.
• Contribute to internal troubleshooting guides, FAQs, and service training materials.
• Participate in Voice of Customer (VOC) feedback loops and continuous improvement programs.
• Promote best practices in safety, documentation, and technical readiness.

Safety & Compliance

• Follow all EHS, electrical, and site safety procedures during field and remote support.
• Demonstrate working knowledge of high-voltage DC systems and PPE standards.
• Support safety reviews and encourage proactive risk awareness.

What You’ll Bring

• Bachelor’s degree in Electrical, Mechanical, or Energy Engineering (or equivalent).
• 3–8 years of experience in energy-storage, renewable power, or industrial service engineering.

• Proven ability to manage multiple service cases or projects simultaneously.
• Familiarity with high-voltage DC safety, PPE, and lockout/tagout procedures.
• Proficiency with Microsoft Office (Excel, PowerPoint, Word).
• Valid driver’s license and willingness to travel domestically up to 40%.

Qualifications

• Experience with containerized or integrated BESS solutions (HVAC, thermal, fire systems).
• Background in lithium-ion battery technology and understanding of associated risks and failure modes.
• Exposure to Power Conversion Systems (PCS) and grid interconnection principles.
• Familiarity with structured problem-solving (5 Whys, FMEA, Fishbone).
• Prior experience with renewable energy systems (PV, wind, or hybrid).
• Safety certifications such as OSHA 30 or NFPA 70E.

Why Join?

• Be part of a growing global leader in renewable energy and energy storage innovation.
