About The Position

Our Hardware Engineering team is seeking a Test Engineer to conduct hardware testing across our EVSE product line and new products in development, while also contributing to sustaining engineering activities. The ideal candidate brings experience in all phases of hardware test; from requirements tracking and test plan development through fixture design, in-house and out-of-house test execution, 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, electrical and mechanical teams. Experience with high-power AC and DC electrical systems and custom PCBA design is desired but an eagerness to learn and adapt in a fast-paced environment is required. We are a small, collaborative team where versatility and ownership are highly valued.

Requirements

4 or more 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.
Ability to leverage AI tools to speed up test automation, embedded development and documentation.
Familiarity with modern analog and digital electronics and electronic circuits.
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.
Demonstrated experience managing workload and project deliverables.
Strong writing, interpersonal, and communication skills.

Nice To Haves

Master’s degree in Electrical Engineering (MSEE)
Knowledge of automotive communication protocols and standards (ISO 15118-2, J1772)
Familiarity with UL safety test standards such as UL 2231-1/2
Experience with certification testing including UL, FCC, and Energy Star
Familiarity with National Electric Code wiring and installation requirements
Ability to perform MTBF analysis
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
Desire to design low-complexity PCBAs, including schematic capture and layout in Altium Designer or equivalent.
Experience testing and debugging Level 2 EV chargers
Experience testing high-volume consumer products
Experience working with automotive OEMs and managing deliverables for their product development processes

Responsibilities

Own both in-house test equipment, methods, documentation, and execution.
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.
Work closely with our in-house compliance team on definition of required pre-screens and risk reduction testing for UL, FCC, and other standards.
Contribute to 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.
Assist design engineers with development testing as needed.
Perform detailed engineering testing 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.
