About the role

You'll help ensure our products are not only engineered for performance and reliability, but also intuitive for customers, manufacturable at scale, and cost-efficient.
The role requires on-site presence at Bellwether's Berkeley HQ.
Identify opportunities for product improvement, cost reduction, and manufacturing optimization.

This role will own significant mechanical design efforts for critical sub-systems and collaborate cross functionally between Engineering, Operations, and Manufacturing teams.
Lead the design and development of complex mechanical subsystems from concept through manufacturing.
Design components and systems optimized for manufacturability, cost efficiency, scalability, and serviceability (DFM/DFA).
Build and test prototypes to validate function, reliability, user interaction, and manufacturability.
Develop engineering requirements, test plans, and documentation to support product development and validation.
Lead and participate in design reviews, including concept reviews, PDRs, CDRs, and production readiness reviews.
Collaborate cross-functionally with electrical, firmware, software, product, industrial design, operations, and supply chain teams to ensure successful product integration and launch.
Troubleshoot complex hardware issues and implement robust engineering solutions.
It's the most consistent and controllable roaster available, has the lowest carbon footprint of any commercial roaster ever made, and was designed by coffee people who want a better future.
Create detailed CAD models, assemblies, and drawings with appropriate GD&T annotations.

7+ years of relevant industry experience in consumer products, appliances, or electro-mechanical systems
Bachelor's degree in Mechanical Engineering (or equivalent experience), with strong fundamentals in statics, dynamics, thermodynamics, heat transfer, and fluid mechanics/dynamics.
Proven experience with a range of manufacturing processes (sheet metal, CNC machining, plastics, welding, die-casting, etc.)
We're seeking a Senior Mechanical Engineer who is passionate about designing products that balance exceptional customer experience with scalable, reliable manufacturing.
Proficiency with CAD tools (OnShape experience preferred; PDM or PLM experience preferred).
