About the Role**
**
We’re looking for a highly capable Mechanical Engineer to own the design and integration of lighting and audio systems for our autonomous delivery robot, DOT. This role requires a balance of strong mechanical fundamentals, system-level thinking, and an eye for human-robot interaction.
You will lead the development of DOT’s interactive lighting systems—ranging from expressive “eyeballs” to headlights and taillight strategies—as well as the mechanical integration of audio hardware that enables clear, reliable two-way communication with customers and law enforcement. You’ll work both independently and with partners to bring these systems from concept through production.
What You’ll Do
- Own end-to-end development of DOT’s lighting systems, including:
- Lead the mechanical design and integration of audio systems, including:
- Translate product and UX requirements into robust mechanical designs that enable intuitive interaction through light and sound
- Develop detailed CAD models, assemblies, and production drawings, and drive design reviews
- Collaborate cross-functionally with EE, firmware, industrial design, and product teams to ensure seamless system integration
- Work with external vendors and partners to co-develop components, manage design trade-offs, and ensure quality
- Drive prototyping, testing, and validation, including environmental (weather, vibration, ingress) and performance testing
- Make informed decisions around materials, manufacturing processes, and cost, ensuring designs are production-ready
- Contribute to system architecture and help define best practices for interactive hardware systems
What We’re Looking For
- Bachelor’s or Master’s degree in Mechanical Engineering or related field
- 5–8 years of experience in mechanical design, ideally in robotics, automotive, or consumer hardware
- Strong proficiency in CAD (SolidWorks, Creo, NX, or similar) with experience delivering production-ready designs
- Demonstrated experience designing and integrating lighting systems or optical/mechatronic components
- Experience packaging and integrating audio components (speakers, microphones) into complex systems
- Solid understanding of DFM/DFA, tolerance stack-ups, and manufacturing processes (e.g., injection molding, sealing, adhesives)
- Experience working directly with suppliers and external partners through development and production
- Ability to operate with high ownership and autonomy, while collaborating effectively across disciplines
Nice to Have
- Experience with automotive or robotic lighting systems
- Familiarity with IP-rated designs and environmental sealing strategies
- Basic understanding of acoustics and optical performance
- Experience designing interactive or expressive hardware systems
- Comfort working in fast-paced, iterative development environments
