Lead Internal Systems Engineer

Visa Sponsorship: Please note that we are unable to provide visa sponsorship for this position.

Proper Voltage is the universal integration layer between advanced batteries and real products. We remove the complexity of voltage mismatch, chemistry limitations, and integration delays that have historically locked product teams into suboptimal power solutions.

Our Battery Operating System (bOS) makes advanced chemistries like sodium-ion, LTO, and lithium-silicon plug-and-play with existing products, no redesign required. This means better safety, performance, and efficiency with zero product compromises.

Job Overview:

As the Internal Systems Engineering Lead at Proper Voltage, you will own the internal processes that turn product designs into certified, manufacturable systems. You will oversee engineering validation, testing, documentation, and release readiness across electrical, mechanical, and firmware teams. Your focus will be on building and enforcing the structure that allows Proper Voltage to scale product development efficiently and meet UL and other regulatory certification requirements.

This role is ideal for a technically strong and highly organized engineer who takes pride in process discipline, validation rigor, and clear documentation. You will be the backbone of engineering operations and a key partner in getting products through certification and into production.

Responsibilities

• Lead the development and enforcement of Proper Voltage’s internal engineering processes, including validation gates, release criteria, and documentation standards
• Maintain and improve engineering tools such as Jira and Duro PLM to ensure traceability from requirements to validation and release
• Coordinate validation testing across electrical, firmware, and mechanical teams, including thermal, vibration, and environmental performance
• Develop and maintain system-level test plans, validation procedures, and result reports for certification and customer requirements
• Manage compliance documentation in support of UL, CE, and other safety standards
• Partner with the VP of Engineering to ensure design freeze, build release, and validation steps are followed consistently
• Work closely with the External Systems team to align internal validation work with customer and regulatory requirements
• Support Manufacturing Operations in preparing pilot builds, quality procedures, and documentation for production release
• Identify opportunities to improve process efficiency without compromising compliance or quality
• Report weekly on validation progress, key risks, and upcoming release milestones
  
  
  

Required Qualifications

• Demonstrated experience developing and managing complex battery and power distribution product architectures, integration plans, and requirement documentation
• 7 or more years of experience in systems, validation, or product engineering for complex hardware systems
• Bachelor’s degree in Electrical, Mechanical, Systems, or Aerospace Engineering
• Proven success implementing validation and certification processes for UL, CE, ISO, or similar standards
• Familiarity with product lifecycle management tools such as Duro, Arena, or equivalent
• Experience defining and maintaining test plans, documentation, and configuration control
• Strong technical background with comfort in multidisciplinary environments
• Excellent written and verbal communication skills
• Highly organized, detail-oriented, and driven to enforce process consistency
  
  
  

Preferred Qualifications

• Experience in startups or high-growth technology companies, demonstrating adaptability and versatility across engineering disciplines
• Knowledge of environmental and reliability testing standards such as UN38.3, MIL-STD-810, or DO-160
• Proficiency with Jira, Confluence, or similar workflow management tools
• Hands-on experience supporting validation or compliance audits
  
  
  

Prior experience with:

• Lithium ion, sodium ion, and other advanced energy storage technologies
• DC-to-DC converters and digital controls in power electronics
• High-voltage battery backup systems and pulsed power systems
• Analog, digital, and mixed-signal circuit design, simulation, and layout
• Thermal management for high-power battery systems
  
  
  

Compensation & Benefits

• Salary range: $150,000 - $200,000 depending on experience and qualifications.
• Equity options as part of the compensation package
• Comprehensive healthcare benefits (medical, dental, vision)
• Generous paid time off and paid holidays (PTO) policy
