Job description

Rainmaker is pioneering a modern cloud seeding system to solve water scarcity and inclement weather problems. We develop and incorporate radar validation, weather-resistant UAS, numerical weather modeling, and sustainable cloud seeds into an effective precipitation enhancement solution.

The Engineering team at Rainmaker works on our UAS, dispersion payload, and in-situ/remote sensing systems. If you are interested in working in an extremely innovative and fast paced environment, where your work directly makes an impact and difference in our operational system, this is a fantastic opportunity.

In this role you will be reporting directly to the Lead Electrical Engineer and will be working on mission critical subsystems for our UAS platform.

Responsibilities

• Rapid Hardware Prototyping: Design and build functional prototypes for UAS subsystems, iterating quickly based on flight test feedback and mission requirements.
• PCB Design: Create schematic and layouts for power distribution, sensor interfaces, payload controllers and communication modules using Altium or KiCad.
• Board Bringup and Testing: Assemble, debug, and validate new PCBs; develop test procedures and fixtures to verify functionality and reliability under flight conditions.
• Documentation: Write technical documentation, prepare fabrication and assembly data for manufacturers.
• Collaborate with cross-functional teams: Mechanical engineers, software engineers, and manufacturing

Experience and Skills

• Experience with PCB design software (Altium or KiCad)
• Familiarity with embedded systems and microcontrollers (Raspberry Pi, NVIDIA Jetson, STM32, ESP32, RP2040)
• Embedded Programming Experience (Rust, Arduino, Python, or C++)
• Familiarity with power electronics circuits. (Buck and boost converters, BMS, power switching circuits)
• Experience with EE Lab equipment (Oscilloscope, Power Supply, DC Load, etc.)
• Experience applying technical ability outside of the classroom (Personal projects, research, extracurriculars, or prior internship/work experience)
