Qualifications

• 4+ years of experience developing and executing test plans for complex products.
• 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.
• 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.
