Job description

Electronics Engineers at Lunar are responsible for the full product development lifecycle of power electronics systems that recast day-to-day energy use in homes and on the go. We are looking for people with a passion to create a more sustainable future and the skills to make that vision a reality. An ideal candidate is enthusiastic and ready to collaborate with a dedicated, cross‑functional team to create innovative, best‑in‑class products starting with home energy storage systems. Engineers at Lunar are hands‑on comfortable with both simulation and real hardware, and able to carry product development from concept stage through high‑volume production.

Lunar Energy was founded to transition homes to 100% clean energy—making our electricity greener, our air cleaner and our energy more safe, secure and reliable for all. We're a fast‑growing, global company building the world's best clean energy products to electrify all homes and connect communities to form clean, resilient virtual power plants.

Any given day at Lunar you may...

• Create the best possible products by contributing to product level features, design, and vision by leveraging your experience and creativity
• Detail-level design of numerous tester interface boards ranging from IOT devices , power electronic systems, DC/DC converters,and inverters.
• Bring up and testing of systems to validate functionality, optimize performance, and evaluate critical characteristics
• Collaborate to create efficient test and validation mechanisms for the individual PCBAs as well as the complete system and support of the development of custom test cards and apparatus
• Work with the ME cross functional team on a bed of nails fixture.
• Work across functions such as mechanical, thermal, reliability, and firmware engineering to optimize the product
• Start-to-finish ownership of the electrical aspect of the system from design through prototype, validation and manufacturing
• Good debugging and troubleshooting skills down to the component level.

Desired Skills:

• BS in Electrical Engineering with 3 years experience in power electronics design,
• Experience with battery management systems ,inverters ,charge systems etc
