## 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.

## What You'll Do

System Design: Lead the architecture and design of complex electrical systems for hardware platforms, defining system-level requirements, interface specifications, and integration strategies. Rapid Hardware Prototyping: Design and build functional prototypes for hardware subsystems, iterating quickly based on test feedback and mission requirements. PCB Design: Create schematic and layouts for power distribution, sensor interfaces, payload controllers and communication modules using Altium. 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, research and manufacturing Required Qualifications Bachelors in Electrical Engineering, Computer Engineering, or significant demonstrated technical ability and professional experience (6+ years of industry work in a related electronics field) 4+ years of professional PCB design experience with Altium (or equivalent), including products developed with digital, mixed-signal, and analog front-end designs. Proven track record leading hardware designs from concept through manufacturing, including DFM/DFT and working directly with contract manufacturers. Deep experience with embedded platforms and microcontrollers (Raspberry Pi, NVIDIA Jetson, STM32, ESP32, RP2040). Experience with high-speed digital design, power integrity, signal integrity, and EMI/EMC considerations. Demonstrated ability to mentor engineers and lead technical reviews Embedded programming experience (C++, C, Rust, or Python), including board bring-up, debugging, and low-level driver development for sensors, communication interfaces (SPI, I2C, UART, CAN), and real-time control loops.

## Preferred Qualifications

Experience designing PCBs and electrical systems capable of sustaining 10kW loads. Experience bringing UAV electrical systems from concept through flight test and production Experience designing power electronics, including BLDC motor controllers, ESCs, and battery management systems (BMS) Familiarity with flight controllers such as Pixhawk, ArduPilot, or custom autopilot hardware Hands-on experience with lithium polymer (LiPo), lithium-ion, and solid-state battery integration and safety Knowledge of RF systems, including datalinks, telemetry radios, SATCOM, and antenna integration

## About Rainmaker Technology Corporation

## Company Overview
- **One-liner**: Rainmaker Technology Corporation uses drone-based cloud seeding to increase precipitation, restore ecosystems, and fight drought.
- **Entity Type**: Public (NASDAQ: RNK) – also described as privately held in some sources; likely a recent public listing with small revenue and high growth.
- **Headquarters**: El Segundo, California, United States
- **Founded**: 2023
- **Founders**: Not publicly available

## Core Business
- **Primary industry**: Climate Technology Product Manufacturing / Weather Modification
- **Target customers**: Governments, water districts, agricultural operators, and environmental restoration organizations (B2G/B2B)
- **Mission or purpose**: “Make rain. Make snow. Make Earth habitable.” – ending water scarcity with next-generation cloud seeding.

## Products & Services
- **[Next-Generation Cloud Seeding System]**: Integrated system of advanced radar, unmanned aircraft (drones), and a cutting-edge weather awareness platform. Used to deliver moderate, predictable increases in precipitation. Aimed at restoring ecosystems, recharging aquifers, and reducing wildfire risk.

## Market Standing
- **Valuation/Market Cap**: Not disclosed; total funding of $31.3M (LinkedIn) or $73.9M (CB Insights) – conflicting reports. Last funding round: Series B of $41M (CB Insights) or Series A of $25M led by Lowercarbon Capital (LinkedIn).
- **Key Metric**: Annual Revenue $7.3M (LinkedIn); Total Funding $31.3M (LinkedIn) / $73.9M (CB Insights)
- **Notable Investors/Partners**: Lowercarbon Capital, Starship Ventures, UP Partners, 1517 Fund, Long Journey Ventures, Garry Tan, and 18+ others (CB Insights).
- **Growth Signals**: 78 employees (+117.4% YoY); 15,285 LinkedIn followers (+148.5% YoY); active job postings: 35 (+337.5% YoY); first U.S. commercial cloud-seeding operation with measured proof of generated precipitation (19 million gallons in 3 hours with 2 drones, August 2026).

## Competitive Advantages
- **Scientific Rigor**: Embedded research organization (Rainmaker Fellows) dedicated to validating results and transparency.
- **First-Mover Proof**: Demonstrated measurable, unambiguous precipitation increase in a commercial operation (USA Today coverage).
- **Integrated Technology**: Combines radar, drones, and weather platform – a modern, proprietary system vs. legacy cloud seeding methods.
- **Location**: Based in El Segundo, CA, part of a deep-tech ecosystem with strong engineering talent.

## Strategic Focus
- **Scale operations**: Expanding into new geographies (Australia, Southern Europe, DACH, India, Middle East); hiring directors of business development for multiple regions.
- **Research & Development**: Launched Rainmaker Fellowship (3-month program) to advance atmospheric science and weather modification.
- **Regulatory & Public Trust**: Committed to transparency and public education about cloud seeding capabilities and limitations.

## Why Work Here
- **Culture**: Described as “an engineering organization and a microcosm of El Segundo's spirit” – iterate quickly, solve the most important problem of our age.
- **Work Environment**: On-site roles in El Segundo, CA, with seasonal field positions across the western U.S. (Utah, Nevada, etc.).
- **Growth**: Rapidly scaling headcount (117% YoY), high-visibility work with real-world environmental impact.
- **Perks**: Opportunity to work on “physical technology” in a deep-tech renaissance; hands-on with drones, radar, and weather systems.
- **Values**: Stewardship of the natural world, scientific rigor, and making freshwater available to all.
