About

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.

Role Overview

The Engineering team at Rainmaker works on our UAS, dispersion payload, and in‑situ/remote sensing systems. In this role you will report directly to the Lead Mechanical Engineer and work 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.
• Test Fixture Design: 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.
• Collaboration: Work with cross‑functional teams including electrical engineers, software engineers, and manufacturing.

Requirements

• Experience with CAD (SolidWorks required; Onshape feature scripting a bonus)
• SolidWorks FEA experience: Linear Static, Linear Dynamic, Nonlinear Dynamic, Thermal
• Experience designing DFM parts
• Experience with basic manufacturing/prototyping using 3D printers
• Basic electrical knowledge; comfortable working with microcontroller breakout boards for simple prototyping
• Demonstrated technical ability outside the classroom (personal projects, research, extracurriculars, or prior internship/work experience)
