About The Company
Rainmaker is ending water scarcity with next-generation cloud seeding.
About the Role

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 Mechanical Engineer and will be working on mission critical subsystems for our UAS platform.

What You'll Do

  • Rapid Hardware Prototyping: Design and build functional prototypes for UAS subsystems, iterating quickly based on flight test feedback and mission requirements.

  • Test fixture design: Help conceptualize, design, build, and run test fixtures for prototype components.

  • FEA: Work with mechanical engineers to define loading and boundary conditions, set up FEA studies, run and validate results.

  • Documentation: Write technical documentation, prepare fabrication and assembly data for manufacturers. 

  • Collaborate with cross-functional teams: Electrical engineers, software engineers, and manufacturing


Required Qualifications

  • Experience with CAD (Solidworks required)

  • Solidworks FEA experience, Linear Static, Linear Dynamic, Nonlinear Dynamic, Thermal.

  • Experience with basic manufacturing/prototyping using 3D printers

  • Sheet metal design and manufacturing experience (preferred) 

  • Past record of having taken a product from the conceptual to production stage (Preferred)

  • Cross functional ability to work with multiple teams (Electrical and Software)
