Full Job Description (Internal)
Detailed job description
We're looking for an experienced mechanical engineer to drive the integration and
development of our robotic systems, leading innovative designs from concept to
deployment. You'll own the full spectrum of mechanical development—from
actuator sizing or design to kinematics and work with teams to prototype and
ultimately produce systems at scale—ensuring reliability, deployability, and
performance. The ideal candidate is a hands-on innovator with deep expertise in
mechatronic systems, combining theoretical knowledge with practical engineering
skills. Experience with actuation systems, electromechanical integration, machine
design, and a track record of bringing mechanical systems to life is essential. If
this sounds like you, please apply!
What youʼll do:
- Own the mechanical design lifecycle: From early concept and proof-of-
concept prototypes to high-volume production, driving all design decisions
around 3D CAD, 2D drawings, material selection, and manufacturability.
- 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.Mechanical Design Engineer Product Design1
- 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.
Qualifications
- Educational Background and Experience
- 7 years of experience taking hardware products from concept to
production, with a strong portfolio of shipped mechanical designs,
preferably in robotics, automotive, consumer product.
- Bachelor's Degree in Mechanical, Aerospace Engineering, or equivalent
experience
- Technical Expertise
- Deep understanding of a wide range of high-volume processes (e.g.,
injection molding, die casting, stamping, machining, bonding).
- Familiarity from past experiences 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; ability to
make first-order engineering judgments.
- Proven record of mechanically integrating electronics (sensors, PCBs,
antennas, batteries) in complex assemblies.
- Ability to lead reviews, influence cross-functional teams, and convey risks
and solutions clearly.
- Hands-On Skills
- Comfort in early-stage, resource-limited startup environments, with a
willingness to get your hands dirty to move quickly.
- Proficiency in various prototyping methods, including machining (mill,
lathe) and sheet metal fabrication, 3D printing, injection molding and other
manufacturing processes
- Experience building and testing proto ... (truncated, view full listing at source)
