About the role
We are seeking an experienced mechanical engineer to lead the integration and development of our robotic systems. Your responsibilities will span from concept to deployment, ensuring reliability, deployability, and performance.
Responsibilities
- Drive all design decisions around 3D CAD, 2D drawings, material selection, and manufacturability—from early concept and proof-of-concept prototypes through high-volume production.
- Develop and refine manufacturing processes: Identify and optimize injection molding, die casting, stamping, machining, adhesives, and bonding methods for new and existing products.
- Ensure reliability and robustness: Perform and interpret reliability tests (HALT/HASS, tolerance stack-ups, environmental testing) and lead corrective design actions.
- Leverage simulation for smart decisions: Use basic FEA tools (thermal, structural, vibrational) and first-order analyses to validate or guide design from early phases onward.
- Lead system integration efforts: Collaborate with electrical and radio teams to balance thermal, EMI, mechanical stability, and accessibility needs in tightly integrated assemblies.
- Prototype and iterate quickly: Build proof-of-concept designs, run experiments, and translate findings into high-yield, mass-production-ready solutions.
- Manage vendor relationships: Evaluate DFM, cost, yield, and timeline trade-offs; work with JDM/CM/ODM partners; own and drive supplier selection where needed.
- Communicate effectively across teams: Conduct design reviews with cross-functional stakeholders, clearly articulating design rationale, risks, and trade-offs.
Requirements
- 7+ years of experience taking hardware products from concept to production, with a strong portfolio of shipped mechanical designs—preferably in robotics, automotive, or consumer products.
- Bachelor's Degree in Mechanical or Aerospace Engineering, or equivalent experience.
- Deep understanding of high-volume manufacturing processes (injection molding, die casting, stamping, machining, bonding).
- Familiarity with HALT/HASS, FMEA, DOE methodologies, and test-to-failure approaches for robust mechanical design.
- Practical understanding of when and how to apply FEA tools, with the ability to make first-order engineering judgments.
- Pioneering record of mechanically integrating electronics (sensors, PCBs, antennas, batteries) in complex assemblies.
- Proven record of leading reviews, influencing cross-functional teams, and conveying risks and solutions clearly.
- Comfort in early-stage, resource-limited startup environments with a willingness to move quickly and hands-on.
- Proficiency in prototyping methods including machining (mill, lathe), sheet metal fabrication, 3D printing, and injection molding.
- Experience building and testing prototypes and analyzing failures to implement improvements.
Qualifications
- Deep expertise in mechatronic systems, combining theoretical knowledge with practical engineering skills.
- Experience with actuation systems, electromechanical integration, machine design.
- A track record of bringing mechanical systems to life.
