Sr. HW Design Engineer

The Impact You’ll Make

We are looking for a talented, hands-on Hardware Design Engineer to join our Power Systems team. In this role, you will design, build, and validate analog and digital circuitry for precision measurement and diagnostic instruments used in renewable energy applications, including solar PV, wind, and battery energy storage systems (BESS). You will work alongside a senior hardware engineer on our Time Domain Reflectometry (TDR) program and contribute across the full hardware development lifecycle, from schematic design and high-speed layout through prototyping, lab testing, and production handover.

This is a great fit for an engineer with a few years of solid circuit design experience who wants to grow their technical depth in high-speed analog, signal processing, and test & measurement hardware at a fast-moving clean energy company. Prior TDR experience is a plus, not a requirement.

Key Responsibilities

Hardware Design & Development

• Design analog and digital circuits including high-speed analog front ends, pulse generation, sampling, and signal conditioning stages
• Create schematics and high-speed, low-noise PCB layouts using Altium Designer, Cadence, or similar tools
• Design and support copper-based communication interfaces and transmission line connections for a range of cable types (coax, twisted pair, MV power cables)
• Select and evaluate components such as ADCs, DACs, op-amps, FPGAs, and microcontrollers
• Support power supply and protection circuit design with guidance from senior engineers

Signal Processing

• Work with firmware and embedded engineers on waveform acquisition, averaging, and fault-distance calculation
• Help develop calibration routines to keep measurements accurate across temperature and load conditions
• Contribute to signal processing approaches that support sub-nanosecond pulse resolution

Prototyping & Validation

• Build, bring up, and debug hardware prototypes in the lab using oscilloscopes, VNAs, spectrum analyzers, and signal generators
• Execute design verification tests and document results against electrical and environmental specifications
• Support EMI/EMC pre-compliance testing and design fixes (roughly 10% of the role)
• Validate measurement accuracy against reference cables and known fault conditions
• Support field trials at renewable energy sites as needed

Documentation & Collaboration

• Produce clear design documentation including schematics, BOMs, design notes, and test reports
• Maintain version-controlled design files
• Support production engineering during design transfer to manufacturing
• Work closely with firmware, software, mechanical, and product teams in an agile environment
• Participate in design reviews and learn from experienced engineers across the team

The Skills You Bring

• Bachelor’s degree in Electrical Engineering, Electronics Engineering, or a closely related discipline
• 3+ years of hands-on experience
