Job summary

Lucid Bots is seeking a senior electrical engineer to own the tether power system end-to-end, delivering approximately 7,000 W continuously (peaks to 10,000 W) from the ground source down the tether into the drone’s propulsion and avionics. You will work with a team of electrical, mechanical, firmware, and test engineers to ship hardware to customers in the real world.

You’ll design high‑voltage DC power transmission, DC‑DC conversion stages, and thermal management; own safety, grounding, and

Qualifications

• Bachelor's or Master's in Electrical Engineering or equivalent hands-on experience.
• Shipped electronics products to production; demonstrated ownership from concept to real-world hardware.
• Experience designing power electronics in multi-kilowatt range, including DC-DC conversion.
• Working knowledge of high-voltage DC systems, conductor sizing, and thermal management.
• Experience integrating power systems with three-phase motor drives/ESCs and validating during load.
• Familiarity with electrical safety standards, grounding and protection design.

Responsibilities

• Design high-voltage DC power transmission architecture for tether to minimize conductor mass and loss.
• Design and specify DC-DC conversion stages for 7 kW continuous load with high efficiency.
• Size tether conductor gauge, insulation, and connectors for 10 kW peak inrush with derating.
• Define current limits, protection thresholds, and fault behavior with onboard distribution.
• Own thermal management of converters, connectors, and cabling across full load range.
• Integrate power system with drone ESCs and flight controller for stable peak transients.
• Coordinate with mechanical on tether reel, strain relief, and cable routing; align with safety/compliance on high-voltage standards.
• Produce schematics, power budgets, test plans and design docs for reviews.
