Posted on Jul 16, 2025
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.
As a mechanical engineer at Rainmaker, you will work with Unmanned Aerial Systems (UAS) and novel aerosol dispersal mechanisms. In this role, you will be responsible for leading the development and optimization of cutting-edge UAS platforms and innovative dispersal systems for a variety of applications.
WHAT YOU'LL DO
- Develop novel aerosol dispersal mechanisms, including nozzle design, flow control, and payload integration
- Conduct computational fluid dynamics (CFD) simulations and wind tunnel testing to validate design concepts
- Collaborate with cross-functional teams, including avionics, controls, and software engineers, to ensure seamless system integration
- Oversee prototype fabrication, testing, and iterative design improvements
- Ensure compliance with relevant safety, regulatory, and industry standards
- Document design processes, test results, and performance data
- Provide technical expertise and support to the broader engineering team
REQUIRED QUALIFICATIONS
- Bachelor's degree in Mechanical Engineering or a related field
- Proficiency in CAD software (e.g., SolidWorks, CATIA) and FEA/CFD tools (e.g., ANSYS, COMSOL)
- Strong understanding of aerodynamics, structural mechanics, and fluid dynamics
- Experience in prototyping, testing, and validating engineering designs
- Excellent problem-solving, critical thinking, and analytical skills
- Ability to work collaboratively in a team environment and communicate technical information effectively
- Knowledge of relevant safety standards and regulatory requirements for UAS operations
- Familiarity with advanced manufacturing techniques, such as 3D printing and composite fabrication, is a plus
