Senior Hardware Design Engineer

1st Avenue Power • Mountain View, CA

15h • $190,000 - $250,000

About The Position

We are looking for a talented and innovative Hardware Design Engineer with significant experience in TDR Equipment Design Engineer to join our R&D team. In this role, you will lead the design, development, and validation of Time Domain Reflectometry instruments and systems tailored for renewable energy applications — including solar PV, wind, and battery energy storage systems (BESS). You will work across the full hardware development lifecycle, from concept and schematic design through to prototyping, testing, and production handover. This is a technically deep, hands-on role ideal for an engineer passionate about precision measurement instrumentation and power systems diagnostics.

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Electronics Engineering, or a closely related discipline
• 5+ years of experience in analog/mixed-signal hardware design, ideally in instrumentation or test & measurement
• Strong proficiency in PCB design — schematic capture and layout using Altium Designer, or equivalent
• Solid understanding of high-speed analog circuit design — signal integrity, transmission line theory, impedance matching
• Hands-on experience with lab instruments: oscilloscopes, VNAs, spectrum analyzers, signal generators
• Familiarity with TDR principles — pulse generation, reflection analysis, fault-distance calculation
• Experience writing or reviewing hardware test plans and design verification reports

Nice To Haves

• Direct experience designing TDR, OTDR, or reflectometry-based instrumentation
• FPGA design experience (Xilinx / Intel) for high-speed data acquisition
• Knowledge of cable types used in renewable energy — DC string cables, MV AC feeders, armored underground cables
• EMC design experience and familiarity with IEC 61000 / FCC Part 15 test processes
• Experience with SPICE simulation tools (LTspice, or similar)
• Familiarity with IEC 61010 safety standard for electrical test & measurement equipment
• Exposure to ISO 9001 or IEC 62443 (industrial cybersecurity for instrumentation)
• Master's degree or PhD in relevant electronics/instrumentation field

Responsibilities

• Design and develop TDR hardware including pulse generation circuits, high-speed analog front ends, sampling circuits, and signal conditioning stages
• Design PCB layouts for high-frequency, low-noise TDR circuits using tools such as Altium Designer, or Cadence
• Select and evaluate components including ADCs, DACs, op-amps, FPGAs, and microcontrollers suitable for TDR applications
• Develop impedance matching networks and transmission line interfaces for various cable types (coax, twisted pair, MV power cables)
• Design power supply and protection circuitry compliant with safety and EMC standards
• Collaborate with firmware/embedded engineers to develop DSP algorithms for TDR waveform acquisition, averaging, and fault-distance calculation
• Define requirements for FPGA or microcontroller-based acquisition systems
• Develop calibration routines and compensation algorithms to ensure measurement accuracy across temperature and load conditions
• Contribute to real-time signal processing pipeline design for sub-nanosecond pulse resolution
• Build and test hardware prototypes in the lab — hands-on bench work with oscilloscopes, VNAs, spectrum analyzers, and signal generators
• Conduct design verification testing (DVT) and design validation testing (DVT) across full environmental and electrical specifications
• Perform EMC pre-compliance testing and support formal EMC/EMI certification
• Validate TDR accuracy against reference cables and known fault conditions
• Support field trials on renewable energy sites to validate performance under real-world conditions
• Ensure designs comply with relevant standards including IEC 61010, IEC 61000 (EMC), and ISO 9001 quality requirements
• Produce detailed design documentation including schematics, BOMs, design rationale, and test reports
• Maintain version-controlled design files and contribute to IP/patent documentation where applicable
• Support production engineering during design transfer and manufacturing ramp-up
• Work closely with software, firmware, mechanical, and product management teams in an agile development environment
• Engage with customers and field engineers to gather requirements and validate designs against real-world needs
• Stay current with advances in TDR technology, high-speed analog design, and renewable energy diagnostics
• Contribute to patent filings and technical publications where appropriate
