What is a battery systems engineer?

A Battery Systems Engineer is responsible for designing, developing, and optimizing battery systems for various applications, such as electric vehicles, energy storage, and consumer electronics. They work on battery pack architecture, thermal management, safety, and integration with other electronic and mechanical components. Their role involves testing, simulation, and ensuring compliance with industry standards to improve performance, efficiency, and reliability.

What are the key skills and qualifications needed to thrive as a battery systems engineer?

A Battery Systems Engineer typically needs a solid background in electrical engineering, electrochemistry, or related fields, along with hands-on experience in battery technologies and system design. Familiarity with simulation tools (such as MATLAB/Simulink), battery management systems (BMS), and relevant safety or automotive certifications (like ISO 26262) is highly valued. Strong problem-solving abilities, teamwork, and effective communication skills help engineers excel in multidisciplinary project environments. These competencies ensure the safe, efficient, and innovative development of battery systems for real-world applications.

What are some typical challenges faced by battery systems engineers in their day-to-day work?

Battery Systems Engineers often encounter challenges such as optimizing performance while ensuring safety, managing thermal issues, and integrating new battery chemistries with existing systems. They must address complex trade-offs between energy density, lifespan, cost, and reliability, frequently collaborating with cross-functional teams in hardware, software, and manufacturing. Staying up-to-date with evolving industry standards and rapid technological advancements is also crucial. Overcoming these challenges requires continuous learning, strong technical analysis skills, and effective communication in a fast-paced environment.

Job description

Please note that we are unable to provide visa sponsorship for this position.
Recruiting agencies: Proper Voltage does not accept unsolicited candidate submissions. Please do not contact any employees directly unless you have an existing engagement with the company.
About Proper Voltage
Proper Voltage is unlocking the next generation of battery technology across robotics, data centers, and defense.
We're building intelligent battery systems that make advanced chemistries (sodium-ion, lithium-titanate, lithium-silicon) work in products that were never designed for them. Humanoid robots can upgrade power systems without redesigning their entire platform. Data centers get safer, cheaper backup power. Drones and autonomous vehicles get higher energy density without lengthy integration cycles.
If you want to work on hard engineering problems that matter this is the place.
Job Overview
We're looking for an experienced mechanical engineer to take ownership of battery pack and module design from concept through production. This is a senior individual-contributor role: you'll drive design decisions independently, lead thermal and structural analysis efforts, and mentor junior engineers, while working closely with electrical, controls, and manufacturing teams to ship real hardware.
Deep experience with thermal analysis and simulation is strongly preferred. We run active thermal test campaigns and simulation workflows, and this role owns that work rather than just supporting it.
What you'll do
Battery Mechanical Design
  • Own mechanical design of battery modules and packs end-to-end, including:
  • Cell integration concepts (prismatic, cylindrical, or pouch formats)
  • Structural components, brackets, and enclosure design
  • Busbar and interconnect geometry
  • Drive design reviews, tolerance stack-up analysis, and DFM decisions
  • Define mechanical interfaces across the assembly and negotiate trade-offs with electrical and controls teams
  • Make final calls on design trade-offs balancing performance, cost, and manufacturability

Thermal Analysis
  • Own thermal simulation setup, execution, and post-processing (SimScale, ANSYS, or equivalent)
  • Evaluate and select TIM and interface materials based on performance and cost trade-offs
  • Design and run thermal test campaigns; independently analyze discharge data and identify root causes of thermal issues
  • Correlate simulation outputs to physical test results and refine models accordingly

Testing & Validation
  • Define and lead mechanical validation test plans, vibration, drop, thermal cycling
  • Own root cause analysis on test findings and drive corrective actions to closure
  • Review and approve test reports and documentation from junior engineers

Documentation, Process & Mentorship
  • Maintain CAD revision history and BOM structure for your subsystems
  • Author engineering documentation, test procedures, and work instructions
  • Lead design review discussions and drive action items to closure
  • Mentor Mechanical Engineer I/II staff on CAD practices, GD&T, and design fundamentals

Required Qualifications
  • Bachelor's degree in Mechanical Engineering or closely related discipline
  • 5+ years of professional mechanical engineering experience, ideally in battery, EV, or energy storage hardware
  • Demonstrated track record taking designs from concept through production
  • Expert-level 3D CAD skills (Onshape, SolidWorks, or equivalent)
  • Strong command of GD&T, tolerance stack-up analysis, and DFM principles
  • Experience owning mechanical subsystems independently, with minimal oversight
  • Ability to mentor junior engineers and lead design review discussions

Preferred Qualifications
  • Proficiency with FEA or CFD tools (SimScale, ANSYS, SolidWorks Simulation) for thermal and structural analysis
  • Direct experience with battery-powered devices, EV systems, or energy storage products
  • Hands-on experience with manufacturing processes - machining, sheet metal, plastics, assembly
  • Working knowledge of UN 38.3 or UL safety standards
  • Experience leading a physical prototype build from CAD through assembled hardware
  • Prior experience mentoring or informally leading other engineers

Compensation & Benefits
  • Salary range: $130,000 - $165,000 annually (commensurate with experience)
  • Equity participation as part of total compensation
  • Comprehensive healthcare benefits (medical, dental, vision)
  • Paid time off and company holidays
  • Opportunity to shape battery mechanical engineering practices as the team scales
