We are seeking a Senior Mechanical Engineer to join our team in San Francisco, CA. At Atoms, we are building the machines that power the next era of progress by integrating Physical AI into industries such as food, mining, and transport. Our mission is to make the physical world more intelligent, efficient, and productive.
Responsibilities
- Sensor & Compute Packaging: Design, package, and integrate advanced autonomous vehicle sensor suites and ruggedized compute housings onto on-road passenger vehicle platforms.
- Drive-by-Wire Integration: Design the electromechanical packaging of drive-by-wire (DBW) actuation systems, custom PCB enclosures, and low-voltage routing.
- Thermal Performance: Ensure all PCB enclosures meet thermal performance requirements.
- Prototype to Production Scaling: Transform early-stage prototype hardware components into refined, scalable designs optimized for high-volume manufacturing assembly.
- Cross-Functional Collaboration: Partner directly with industrial designers, in-house manufacturing technicians, external vendors, and manufacturing engineering to execute rapid prototype part runs.
- Engineering Documentation: Create and maintain highly disciplined engineering documentation, including complex CAD models, production-ready drawings, Bills of Materials (BOMs), and clear installation manuals.
- Rapid Prototyping Execution: Fabricate and iterate physical mockups using a diverse suite of rapid prototyping methods, ensuring designs are optimized for CNC machining, sheet metal fabrication, and 3D printing.
- Testing & System Validation: Establish and run rigorous physical testing and validation protocols for electromechanical systems to guarantee environmental durability, shock absorption, and long-term reliability.
Requirements
- Bachelor's degree in Mechanical Engineering, Mechatronics, or a closely related field.
- 5+ years of non-internship professional Mechanical Design Engineering experience.
