Principle Electrical Hardware Engineer

A leader in cutting-edge commercial solar and energy storage solutions, delivering innovative, cost-effective, and scalable technology to power the future of clean energy. We are building a world-class team of professionals passionate about renewable energy and sustainable solutions. If you're looking for an opportunity to make a meaningful impact in a fast-growing, mission-driven company, this is the place for you. About the Role This role is ideal for a hands‑on electrical engineering leader who thrives at the intersection of power electronics, embedded systems, and product development. As a Principal Electrical Hardware Engineer, you will own the architecture and execution of critical power conversion and control hardware that drives our energy platform. You’ll play a key role in shaping next‑generation products from early concept through production, balancing deep technical expertise with practical engineering execution. This position requires someone who is equally comfortable designing complex mixed‑signal hardware, troubleshooting systems at the bench, collaborating across disciplines, and mentoring other engineers to elevate overall team performance. Key Responsibilities Lead the electrical hardware architecture and development of BMS, DC‑DC, and inverter subsystems across the product portfolio, from concept through production release Design, develop, and validate mixed‑signal hardware including power stages, gate drivers, sensing circuits, isolation circuitry, analog front ends, and microcontroller‑based control systems Create schematics and perform hands‑on PCB layout in Altium, including high current routing, controlled impedance design, thermal management, and EMI‑conscious placement and routing practices Design and specify magnetic components such as transformers, inductors, and common‑mode chokes, while collaborating with vendors on custom solutions Collaborate with firmware engineers to develop, implement, and tune closed‑loop digital control systems for power conversion applications Develop and debug communication interfaces including I2C, SPI, UART, CAN, RS‑485, and USB across embedded and system‑level architectures Lead hardware bring‑up, validation, and troubleshooting using lab equipment such as oscilloscopes, spectrum analyzers, electronic loads, thermal cameras, and solar array simulators Drive design for manufacturability (DFM) and design for testability (DFT), supporting pilot production builds, factory test development, and manufacturing ramp activities Ensure compliance with EMI/EMC, safety, and reliability requirements, including in‑house pre‑compliance testing and coordination with external certification labs Mentor and guide junior and mid‑level engineers, establishing high standards for engineering quality, documentation, and design review processes Partner cross‑functionally with mechanical, firmware, systems, manufacturing, and product teams to deliver fully integrated hardware solutions Qualifications Bachelor’s degree or higher in Electrical Engineering from an accredited institution 10+ years of industry experience in power electronics and mixed‑signal hardware design, with a proven track record of successfully bringing products from concept to production Extensive hands‑on experience designing Battery Management System (BMS) hardware for lithium‑ion battery systems, including cell monitoring, balancing, protection, isolated communication, and contactor control Strong experience designing inverters and/or bidirectional DC‑DC power conversion systems for solar, energy storage, or related renewable energy applications Expert proficiency with Altium Designer, including schematic capture, multi‑layer PCB layout for power electronics, library management, and ECO workflows Deep understanding of analog and mixed‑signal circuit design, including op amps, comparators, ADC/DAC interfaces, isolation circuits, gate drivers, and current voltage sensing. Experience with microcontroller‑based system design and the ability to collaborate effectively with firmware teams on embedded C development and debugging Strong hands‑on laboratory and debugging experience using oscilloscopes, spectrum analyzers, electronic loads, solar array simulators, network analyzers, and thermal imaging tools Comfortable soldering, reworking, and modifying prototype hardware as needed during development and testing Working knowledge of EMI/EMC, safety, and regulatory compliance practices for grid‑connected power electronics, with the ability to design for compliance throughout the development lifecycle Excellent written and verbal communication skills, including the ability to clearly document technical designs and communicate complex technical issues to both technical and non‑technical audiences. What We Offer Up to $200,00 a year DOE High‑impact leadership role in a fast‑growing clean energy company Work Authorization Requirement Candidates must be authorized to work in the United States on a full‑time basis without the need for current or future employer sponsorship. #J-18808-Ljbffr Engtal
