Reporting to: VP of Engineering

Location: Onsite in Boulder, CO

About the Role

Our Hardware Engineering team is seeking a Senior Electrical Test Engineer to lead hardware testing across our EVSE product line and new products in development, while also contributing to sustaining engineering activities. The ideal candidate brings deep expertise in all phases of hardware test; from requirements tracking and test plan development through fixture design, in-house and out-of-house test execution, and production line validation, combined with hands-on sustaining engineering skills including field failure investigation, root cause analysis, and minor PCBA design changes.

This role will partner closely with external test labs, contract manufacturers, automotive OEM customers, and internal firmware, mechanical, and compliance teams. Experience with high-power AC and DC electrical systems and custom PCBA design is essential. We are a small, collaborative team where versatility and ownership are highly valued.

Responsibilities

Electrical Test Engineering (75%)

• Own requirements tracking and verification, including verification method determination
• Develop test profiles for reliability and accelerated environmental testing including thermal fatigue, thermal shock, corrosion/weathering, and ingress testing
• Generate high-quality reports to share test results and analysis with customers and internal stakeholders
• Work with engineering and factory test teams to develop overall product test strategies to help turn prototype designs into production units
• Validate new product features in collaboration with the engineering team
• Own both in-house test equipment, methods, documentation, and execution
• Work closely with our in-house compliance team on definition of required pre-screens and risk reduction testing for UL, FCC, and other standards
• Partner with contract manufacturers and in-house operations teams to design PCBAs used in custom test fixture or review proposed production line test solutions
• Assist design engineers with development testing as needed

Sustaining Engineering (25%)

• Perform detailed engineering investigations of RMA units coordinating with customer support and engineering teams as necessary
• Execute root cause analysis on field failures and present findings and recommended mitigations to triage teams, design engineers, and management
• Make targeted electrical design changes for minor improvements to existing products, including obsolete component replacements and corrections identified through failure analysis
• Collaborate cross-functionally with firmware, mechanical, quality and manufacturing engineers as required

Required Skills & Qualifications

Required

• 7-10 years of experience developing and executing test plans for complex products as a test engineer, electrical engineer, or related role
• Bachelor's degree in Electrical Engineering (BSEE)
• Competence with test equipment such as oscilloscopes, grid simulators/programmable AC sources, electronic loads, current-probes and power analyzers
• Experience with test automation scripting (e.g., Python) for data acquisition and control
• Knowledge of modern analog and digital electronics and electronic circuits
• Familiarity with switching converters, inverters, and AC/DC power distribution
• Experience with high-power AC electrical systems (3-phase and split-phase 240V) and high-voltage DC power systems
• Experience in testing and debugging for signal integrity / power integrity
• Familiarity with standard interfaces such as Ethernet, CAN, I2C, SPI, USB, etc..
• Ability to read and understand electrical schematics and ECAD data; experience developing in-house test systems including test racks and harnessing
• Experience designing and bringing up low-complexity PCBAs, including schematic capture and layout in Altium Designer or equivalent
• Demonstrated experience managing workload and project deliverables
• Strong writing, interpersonal, and communication skills

Strongly Preferred

• Master's degree in Electrical Engineering (MSEE)
• Expert-level Python-based lab automation
• Knowledge of automotive communication protocols and standards (ISO 15118-2, J1772)
• Familiarity with UL safety test standards such as UL 2231-1/2
• Experience working with automotive OEMs and managing deliverables for their product development processes
• Experience with certification testing including UL, FCC, and Energy Star
• Familiarity with National Electric Code wiring and installation requirements
• Ability to perform MTBF analysis
• Experience designing and owning complex PCBA designs implementing high voltage and high speed signaling
• Experience testing and debugging Level 2 EV chargers
• Experience testing high-volume consumer products
• Expert-level Altium Designer proficiency
