Electronics Test Engineer (Contract)

About Moon Five

Moon Five helps multi-family homes unlock the full potential of their existing electrical infrastructure — starting with plug-and-play direct-to-tenant EV charging at $50/month and zero upfront costs.

Moon Five’s hardware, software, and deployment optimizations allows us to skip the costly infrastructure upgrade and long installation cycles, enabling rapid EV charging adoption today while setting the stage for future energy services like load balancing, DERs, and affordable backup energy. Our system, called Horizon, consists of an EV charger, apartment energy management system, and building energy management system that measure the amount of current being used at an apartment and throttle the energy going to the charger to keep the apartment breaker from tripping.

Moon Five is a Los Angeles Cleantech Incubator (LACI) portfolio company, and participated in Berkeley Skydeck, Creative Destruction Labs, and Cleantech Open and is an Energy Power Research Institute’s (EPRI) Incubatenergy Finalist.

Job Description

We are seeking a skilled Electrical Integration and Test (I&T) engineer for a contract role for up to 40 hours a week on a 1-3 month contract. The role supports bring up and calibration of Moon Five’s generation 2 EV chargers and energy management systems at our Berkeley headquarters. This hands-on role involves electronics prototype assembly, testing, calibration, and troubleshooting alongside our team of in-person and remote engineers.

Responsibilities

• Assemble and run calibration tests on test station (bring up)

• Support first-power, bring-up, and debug of prototype charging and energy management units

• Conduct functional tests on EVSE and energy management systems including functional validation, safety checks, and power calibration

• Perform detailed electrical testing using oscilloscopes, multimeters, power analyzers, electronic loads, spectrum analyzers, and custom-built testing equipment to validate design performance

• Troubleshoot electrical systems at component and system levels, identifying root causes of failures and implementing corrective actions

• Collaborate with engineering to improve test procedures, develop automated test sequences, and optimize production workflows

• Support production ramp-up by creating assembly work instructions, SOPs, and implementing quality control procedures

• Assist with pre-compliance testing setup and data collection to prepare for formal NRTL certification testing

Qualifications

• Associate degree in Electronics Technology, Electrical Engineering Technology, or equivalent technical certification

• 3+ years of hands-on experience with electronic circuit and/ or industrial assembly, testing, and troubleshooting

• Proficiency with electronic test equipment including oscilloscopes, DMMs, power supplies, electronic loads, and signal generators

• Experience reading electrical schematics, PCB layouts, and mechanical assembly drawings

• Familiarity with UART, SPI and RS485 protocols

• Knowledge of electrical safety procedures for high voltage systems (up to 480VAC) and lockout/tagout (LOTO) protocols

• Ability to work independently with minimal supervision while maintaining detailed documentation and following procedures

• Familiarity with automated testing environments and Supervisory Control and Data Acquisition) SCADA

What Makes You Stand Out

• Excellent communication skills for interfacing with engineers, production staff, and field service teams

• Experience with automotive electronics, EV charging equipment, or renewable energy systems

• Experience with Wi-Fi mesh and LoRa protocols

• Familiarity with safety standards such as UL 1741, UL 2231-1/-2, or IEC 61851 for EV charging equipment

• Familiarity with soldering techniques for through-hole and surface mount components, including rework and repair

• Basic mechanical skills including use of hand tools, drill press, and measurement instruments (calipers, micrometers)

• Experience with Python or other automation tools for test sequence development

• Experience supporting regulatory compliance testing (UL, FCC, CE marking processes)

• Hands-on experience with high-power testing (>10kW) and split-phase electrical systems

• Knowledge of electrical contractor installation practices

• Strong problem-solving skills with ability to work effectively under tight project deadlines

• Willingness to occasionally travel to customer sites for installation support and troubleshooting

Compensation & Perks

• Company lunch once a week

• Compensation Range: $50 - 80/hour

• Opportunity to shape the future of a rapidly growing company
