Hardware Design Engineer

Hardware Design Engineer Our Mission SPAN is enabling electrification for all ⚡ We are a mission-driven company designing, building, and deploying products that electrify the built environment, reduce carbon emissions, and slow the effects of climate change. - Decarbonization is the process to reduce or remove greenhouse gas emissions, especially carbon dioxide, from entering our atmosphere. - Electrification is the process of replacing fossil fuel appliances that run on gas or oil with all-electric upgrades for a cleaner way to power our lives. At SPAN, we believe in: - Enabling homes and vehicles powered by clean energy - Making electrification upgrades possible - Building more resilient homes with reliable backup - Designing a flexible and distributed electrical grid Role Overview We are looking for a focused and proactive Hardware Design Engineer to join our product development team. In this role, you will be responsible for the end-to-end hardware lifecycle—from initial circuit design and simulation to PCB layout, prototype bring-up, and manufacturing support. You will play a key role in developing robust power electronics and embedded systems, ensuring our products meet the highest standards of reliability and performance. Key Responsibilities 1. Design & Development - Circuit Design: Develop complex analog, digital, and mixed-signal circuits, with a specific focus on Power Electronics (AC/DC, DC/DC, and DC/AC conversion). - Schematic & Layout: Execute high-quality schematic capture and multi-layer PCB layouts (4+ layers) using industry-standard EDA tools. - Simulation: Perform rigorous circuit simulations (LTspice/PSpice/PSIM) to validate designs before prototyping. - Component Selection: Select components based on performance, cost, and long-term availability (BOM lifecycle management). 2. Validation & Testing - Hardware Bring-up: Perform hands-on assembly, debugging, and functional testing of PCBA prototypes. - Lab Expertise: Utilize DSOs, Logic Analyzers, Function Generator to validate hardware against design specifications. - Rework: Conduct fine-pitch SMD soldering and board-level modifications as needed during the prototyping phase. 3. Compliance & Manufacturing - EMI/EMC & Safety: Support pre-compliance testing and mitigation. - DFM/DFA/DFT: Collaborate with manufacturing partners to ensure designs are optimized for high-volume fabrication, assembly, and automated testing. - Documentation: Generate comprehensive Gerber files, assembly drawings, test procedures, and technical design notes. Technical Requirements EDA Tools - Proficiency in Altium Designer (preferred), OrCAD, or KiCad. Power Electronics - Deep understanding of switching power supplies (SMPS), energy storage systems, and magnetics design (inductor/transformer selection). High-Speed Design - Experience with signal integrity (SI) and power integrity (PI) for interfaces like USB, Ethernet, and LVDS. Communication - Hands-on experience with SPI, I2C, UART, CAN, MODBUS, and JTAG. Core Competencies - Problem Solving: A structured approach to debugging complex hardware failures. - Collaborative Mindset: Ability to contribute to hardware architecture discussions and work across firmware and mechanical teams. - Accountability: Strong ownership of design quality, from the first resistor to the final production-ready board. - Planning: Ability to estimate engineering effort and manage timelines for complex PCB projects. Nice to Have - Experience with IoT/Connected devices or home electrification products. - Exposure to Hardware Security (Secure Boot, HSM integration). - Knowledge of thermal simulation and reliability modeling tools. - Experience managing high-volume supply chains in the India/Asia region.
