Senior Mechanical Engineer

About the role

We are seeking a Mechanical Engineer to help design the physical architecture of our next-generation autonomous transport platforms. In this role, you will bridge the gap between industrial design and vehicle production, transforming complex prototypes into scalable realities.

Responsibilities

• Design, package, and integrate advanced autonomous vehicle sensor suites and ruggedized compute housings onto on-road passenger vehicle platforms.
• Design the electromechanical packaging of drive-by-wire (DBW) actuation systems, custom PCB enclosures, and low-voltage routing.
• 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.
• Partner directly with industrial designers, in-house manufacturing technicians, external vendors, and manufacturing engineering to execute rapid prototype part runs.
• Create and maintain highly disciplined engineering documentation, including complex CAD models, production-ready drawings, Bills of Materials (BOMs), and clear installation manuals.
• 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.
• 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.
• Proficient hands-on design experience utilizing 3D CAD modeling software such as SolidWorks, Catia or NX.
• Prior experience or deep familiarity with the structural integration of hardware onto automotive platforms, mobile robotics, or heavy mechatronic equipment.
• Strong knowledge of manufacturing processes, with direct experience designing for CNC machining, sheet metal stamping, and injection molding.
• Demonstrated ability to create accurate, production-level engineering drawings and meticulous component documentation using GD&T where applicable.
• Exceptional aptitude for navigating ambiguity and collaborating dynamically within a fast-paced, hardware-in-the-loop startup environment.

Qualifications

• Experience with drive-by-wire (DBW) systems and electromechanical packaging.
• Understanding of thermal management and its impact on system performance.
• Knowledge of automotive standards and regulations relevant to autonomous vehicles.
• Ability to work effectively in a cross-functional team environment.

Skills

• Advanced proficiency in 3D CAD modeling software (SolidWorks, Catia, NX).
• Experience with rapid prototyping techniques (CNC machining, sheet metal fabrication, 3D printing).
• Strong understanding of mechanical principles and their application in real-world scenarios.
• Excellent problem-solving and analytical skills.
• Effective communication and collaboration skills.
