Devops engineer Jobs in Richmond, CA

• Team is scaling responsibilities across a small full-time group.
  
• Increasing complexity in battery energy storage systems (BESS).
  
• Need a dedicated owner for isolation %2B power distribution workstreams.
  
• Current team has been handling this work, but needs focused expertise to proactively identify and solve system-level issues.
  

Mission / About the Role

They are hiring a Senior Electrical Engineer to own the work streams electrical isolation barrier designs between the 600VAC, 2kV DC and, 50V DC systems and power budgeting and ampacity analysis across the 600V phase and split phase AC systems. You will work directly with the Staff EE and cross-functional partners in hardware, compliance, and test.

• Focused on system-level power distribution %2B isolation strategy (not PCB design).
  
• Supporting complex BESS (battery energy storage) systems.
  
• This person will partner closely with Shraddha (design owner) and help drive execution, analysis, and system understanding.
  

Top 3 Qualifications / Responsibilities

1. Design the robust power distribution system with the balanced 3-phase and split-phase AC loads (600V%2B).
   
2. Define the isolation specifications (clearance, creepage, and dielectric withstand specifications) for the HVDC (2kV%2B), HVAC (600V) and LVDC (<50V) systems.
   
3. Design the custom isolation barriers compliant with UL508A, IEC 60664-1, or equivalent.
   

Key Responsibilities

• Define component- and material-level isolation specifications for all parts in the signal and power path between the 50VDC, 600V AC domain and the 2 kV DC battery domain.
  
• Specify the component level isolation specifications/test criteria for the electrical components. Design custom isolation barriers for components that do not natively meet required isolation criteria.
  
• Ensure isolation architecture is compliant with UL508A and is fully captured in DFMEA.
  
• Drive isolation reviews with compliance, safety, and mechanical design stakeholders.
  
• Build and maintain a per-phase ampacity rollup for all 600V AC loads, covering both 3-phase and split-phase consumers.
  
• Develop a load power budget across the system's defined operating modes, identifying worst-case loading.
  
• Analyze phase balance and flag imbalance risks to the upstream breaker; recommend rebalancing or load-shedding strategies.
  
• Size upstream protection and feeder conductors; coordinate with the panel designer on implementation.
  
• Present design reviews and defend technical decisions to cross-functional stakeholders.
  

Additional Context:

• ~50% focused on power/load analysis, ampacity, and distribution modeling.
  
• ~50% focused on understanding BESS system architecture and how power flows through it.
  
• Identify gaps, bridge system-level issues, and propose solutions.
  
• Not expected to fully own schematics, but panel/schematic exposure is helpful.
  

Required Qualifications

• BS in Electrical Engineering or equivalent.
  
• 8%2B years of experience in high-power electrical system or panel design.
  
• Proficiency in EPLAN or equivalent CAD/electrical schematic design tools
  
• Demonstrated experience designing galvanic isolation between high-voltage AC and DC domains, including clearance/creepage analysis and dielectric coordination.
  
• Strong working knowledge of UL508A (or equivalent IEC 61439) panel design requirements.
  
• Hands-on experience with 600V AC 3-phase and split-phase distribution, including ampacity calculations, phase balancing, and protection coordination per NEC.
  
• Experience selecting/developing high power high voltage power conversion devices.
  
• Experience working in high-voltage, safety-critical environments (60V%2B).
  
• Strong critical thinking %2B problem-solving ability is key.
  
• Comfortable working cross-functionally and in ambiguous system environments.
  

Preferred Qualifications:

• Experience authoring and defending DFMEA content for high-voltage electrical systems.
  
• EV, battery test, or energy storage systems experience, particularly at battery pack voltages of 10 kV DC or higher.
  
• Background in control panel design strongly preferred.
  
• Experience with high-power test equipment panel design (10 kW%2B loads).
  
• Familiarity with Arena PLM or equivalent.
  
• Familiarity with MATLAB or simulation tools.
  

Team Structure

• Reports to: (Hiring Manager).
  
• Dotted line to: (Technical Lead / Design Owner).
  
• Highly collaborative environment across teams like: Electrical, Mechanical, Materials, Safety/Compliance.
  

Key Notes / Nuances

• This is a system-level electrical role, not a PCB design role.
  
• Focus is on power distribution, isolation, and safety architecture.
  
• Isolation specs are partially definedthis person will interpret, validate, and implement.
  
• Will work closely with design owner vs. fully owning architecture from scratch.
  
• Strong emphasis on understanding the system, identifying gaps, and proposing solutions.
