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

• 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).

• 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.

• 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.

Qualifications

Education: B.E./B.Tech http://B.Tech or M.Tech http://M.Tech in Electronics Engineering, Electrical Engineering, or a related field.

Experience: 3–5 years of proven experience in professional hardware product development.
