About Humble Robotics
Working at Humble Robotics means taking on the biggest change in ground transportation in decades. We’re building an autonomous, zero-emissions hauler that dramatically lowers the cost of freight with groundbreaking vision-based AI, designed for today’s global logistics network. 
 
We’re a fast-moving, close-knit team of AV industry veterans and innovative thinkers. We don’t believe culture can be engineered – but when it falls into place, it’s a once-in-a-lifetime adventure.
 
Progress has never felt so present.
 
Position Overview
Own design, integration, and early validation of new mechanical hardware for large autonomous vehicles.
Key Responsibilities

  • Design, prototype, and validate mechanical systems and components for autonomous trucking platforms

  • Create detailed CAD models and engineering drawings for fabrication and assembly

  • Work hands-on in the shop to build, modify, and test hardware

  • Collaborate cross-functionally with electrical, software, and systems engineers

  • Support integration of sensors, compute hardware, and vehicle subsystems

  • Conduct root cause analysis and implement design improvements

  • Develop and execute test plans (bench and vehicle-level)

  • Manage parts sourcing, fabrication vendors, and assembly processes

  • Contribute to rapid iteration cycles and field deployments

Required Qualifications

  • Bachelor’s degree in Mechanical Engineering or related engineering discipline

  • 2+ years of relevant industry or internship experience

  • Strong hands-on experience with shop tools, including:

    • Manual mill and lathe

    • Laser cutter

    • Power tools (drills, grinders, etc.)

  • Proficiency in CAD (SolidWorks preferred)

  • Familiarity with GD&T and tolerance stack-ups

  • Experience designing for manufacturability and assembly (DFM/DFA)

  • Ability to build and test prototypes independently

  • Strong problem-solving skills and attention to detail

  • Comfortable working in a fast-paced, ambiguous startup environment

  • Familiarity with sheet metal, machining, and rapid prototyping methods (3D printing, CNC, etc.)
Preferred Qualifications

  • Experience working on large vehicles, or autonomous vehicles

  • Basic understanding of electrical systems and sensor integration

  • Experience with PLM/PDM systems

  • Familiarity with FEA or other simulation tools

  • Experience supporting field testing or deployments

  • Startup or small-team experience

As part of the interview process, we may use Artificial Intelligence (AI) tools to compare your qualifications and experience to the job description. A human reviews all AI output and makes a final hiring decision. Humble Robotics does not rely on the output to make any employment decisions. Some applicants may have a legal right to opt-out of the use of AI as part of our interview process. Contact legal@humblerobotics.ai to exercise this right or if you have further questions on the use of AI tools in our hiring process.

Humble Robotics will consider qualified applicants with arrest and conviction records in a manner consistent with local ordinances.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
