Lead Digital Power Electrical Hardware 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) leverages high-performance DC-DC converters to allow the battery pack’s output voltage to become a software-defined parameter. That makes advanced chemistries like sodium-ion, LTO, and advanced Li-ion plug-and-play with existing products, no redesign required. This means better safety, performance, and efficiency with zero product compromises.

Instead of a BMS or chemistry startup, we’re the system that bridges the gap between breakthrough power technologies and the products that need them most.

Power should be a design advantage, a limitation. Join us in making advanced batteries universally accessible.

We are in search of a Lead Digital Power Electrical Hardware Engineer who is passionate, versatile, and highly motivated to join our nimble team of multi-disciplinary engineers. This role is for a hands‑on leader who has broad experience in digital power electronics, including DC‑DC conversion, encompassing design, hardware, testing, and manufacturing. This position offers the opportunity to drive innovation, define product roadmaps, and shape product architecture within a collaborative, dynamic environment as part of a rapidly growing startup company.

• Lead the development and enforcement of Proper Voltage’s internal engineering processes, including validation gates, release criteria, and documentation standards.
• Lead system‑level and detailed design efforts for cutting‑edge digital DC‑DC power converters used across our product range, including industrial applications, robotics, LEVs, utility‑scale power systems, and many other battery‑powered applications.
• Perform design calculations, component selection, circuit design, schematic capture, and PCB layout and routing for high‑performance, mixed‑signal power electronics for use in low‑ and high‑voltage applications.
• Document, prototype, test, and debug both evolutionary and novel power converters to continually expand our market reach.
• Collaborate with cross‑functional teams to develop the roadmap for the evolution of our DC‑DC converters and related technology.
• Drive continuous improvements in our core system functionalities, including battery management, DC‑DC power conversion, and mixed analog/digital design for sensing and control.
• Collaborate with cross‑functional teams to transition designs to high‑volume production, providing production‑ready schematics, PCB layouts, and bills of materials.
• Support programming, calibration, debugging, and quality control processes.
• Lead efforts to optimize power electronics in key metrics such as power density, size, weight, and cost.
• Mentor and manage team members, delegating tasks and overseeing project progress within the electrical engineering department.
• Help grow the power conversion team, eventually managing direct reports.
• Exercise a high degree of autonomy, take ownership, and contribute as a key individual to project milestones and objectives.
• Ability to either work in person at our Carlsbad, CA office or travel there as needed with a demonstrated track record of highly efficient, collaborative remote work.

• B.S., M.S., or Ph.D. in Computer Engineering, Computer Science, or Electrical Engineering.
• 4+ years of experience with a strong record developing digital power electronics for applications requiring kW+ power levels spanning tens of volts to hundreds of volts.
• Proficiency incircuit design software (SPICE, Altium) with an emphasis on power electronics, DC‑DC conversion, and mixed‑signal PCB layout; experience with Altium is a plus.
• Proficiency with bench tools (power supplies, loads, multimeters, oscilloscopes) and high‑voltage safety principles (isolation, hi‑pot testing, certification requirements).
• Analog and digital design experience,including thermal design…
