Job
Description
Span s Hardware Team is seeking an experienced and driven Electrical Engineer to own critical electronic design on Span s next generation of products. As a Staff Electrical Engineer, you will be responsible for developing state-of-the-art energy management hardware that will ship to market and power people s homes. You will own the design through all stages of development, collaborating with the Systems Architecture, RD, Mechanical Engineering, Test, and Manufacturing teams to bring your concept to life. What you'll Do: Lead pioneering high-reliability energy management Hardware design from concept to mass production. Develop and validate highly complex single-board computer designs. Design power, mixed signal, and digital circuits and circuit components. Collaborate with Systems Architect and Product Design leadership on architecting complex electrical systems, covering precision digital, analog, and power domains. Own PCB/PCBA designs and work with Mechanical, Thermal, and OPs teams on the specification of mechanical interfaces, thermal interfaces, and overall product function. Work closely with Firmware and Software teams to define platform architecture and develop features, self-tests, and testing methodologies. Develop, plan, and perform tests related to functional validation, regulatory compliance, and reliability, with limited resources. Design PCB/As to comply with creepage and clearance rules, high voltage safety concerns, high speed signal integrity requirements, low noise analog design best practices, EMC/EMI regulations, and thermal and mechanical design requirements. Work with contract manufacturers and manufacturing test teams throughout the full product lifecycle to ensure parts are made to specification and achieve our standards for product quality and yield. About You What We Need: BS or MS in Electrical Engineering or Electrical Engineering/Computer Science. 8+ years of experience developing products from initial concepts to mass production, including the design of PCBAs. Hands-on approach, whether it be building a prototype or performing in-lab testing. Experience owning analog and mixed-signal circuit designs, specifying system interfaces, and architecture with diverse teams. Strong grasp on fundamentals covering circuit analysis, electromagnetics, as we'll as basic feedback and control theory. Experience working closely with contract manufacturers and suppliers, and internal cross functional teams. Multi-layer PCB design knowledge. What Makes You Stand Out: Experience with designing compute-intensive applications, with high-speed interfaces and EMI mitigation experience. Experience with RF/Antenna design and testing (WiFi/BLE, LTE, Zigbee, LoRa, etc) Experience with high voltage design (which in our context means up to 600V) and power electronics. ACDC design and validation and test. Design experience with products that connect to the electrical grid. Knowledge of national and international safety and regulatory requirements such as UL, National Electric Code(NEC), FCC, IEC, and ISO, and how to design to those standards. Experience meeting IEC 61000-4-x requirements in design; especially ESD, surge, and EFT. Designed magnetic devices such as transformers or inductors. Designed electromechanical devices such as solenoid actuators or relays. Designed high-voltage isolated power and data interfaces. Experience with the development of performance validation, environmental, and reliability tests. Design experience with thermally sensitive products.
