Mechanical Systems Integration Engineer

Join the team bringing advanced autonomy to the built world

At Bedrock, we're moving AI out of the lab and into the real world. Our team includes veterans who helped launch Waymo, scaled Segment to a $3.2B acquisition, and grew Uber Freight to $5B in revenue. Today, we're deploying autonomous systems on heavy construction equipment across the country, improving safety on job sites and accelerating schedules on critical infrastructure projects.

We're not here debating the future of AI. We're deploying it in the real world. In just two years, we've raised $350M and achieved the first fully autonomous excavator deployments in construction.

As a Mechanical Systems Integration Engineer, you will be responsible for the physical integration of sensors, compute hardware, actuators, and supporting subsystems onto our next-generation autonomous construction machines. Working closely with electrical, software, manufacturing, operations, and supply chain teams, you will translate system-level requirements into robust mechanical designs optimized for scale, reliability, manufacturing, industrial design, and operations, which survive demanding real-world environments — from vibration and shock, to dust, debris, and weather exposure.

Key Responsibilities

• Mechanical Integration Design: Develop mounting brackets, enclosures, class A surfaces, and structural interfaces for sensors (cameras, LiDAR, radar, IMUs), compute units, and ancillary hardware onto vehicle platforms.
• 3D CAD Design: Create detailed part and assembly models using Onshape including GD&T-compliant drawings for fabrication and vendor sourcing.
• Routing & Packaging: Collaborate with cross functional teams to define physical routing paths for wire harnesses, fluid lines, and cooling components within tight mechanical envelopes.
• Environmental Protection: Design and select appropriate sealing, gasketing, and protective enclosures (IP-rated) to safeguard sensitive electronics from moisture, dust, and contamination.
• Prototype Build Support: Hands-on participation in prototype builds, including hardware installation, fit-check validation, and iterative design refinement on the shop floor.
• Structural & Thermal Analysis: Perform first-order hand calculations and collaborate with analysis teams to validate designs for static loads, vibration fatigue, and thermal dissipation.
• Supplier & Vendor Management: Work with fabrication vendors and contract manufacturers to source custom brackets, enclosures, and machined components from RFQ through delivery.
• Retrofit Strategy: Design non-invasive mechanical integration solutions for OEM donor vehicles, preserving factory structure and serviceability while accommodating new autonomous hardware.
• Cross-Functional Collaboration: Partner with electrical, software, and field teams during bring-up and validation phases to resolve fit, form, and function issues on prototype machines.
• BOM & Documentation: Maintain accurate Bills of Materials, assembly drawings, and integration documentation throughout the product lifecycle.

Qualifications & Skills

• Education: Bachelor's degree in Mechanical Engineering, Mechatronics, or a related field, or equivalent experience
• Experience: 5+ years of experience in mechanical design and integration for vehicles, heavy machinery, robotics, or industrial equipment.
• CAD Proficiency: Strong hands-on experience with 3D CAD such as Onshape, SolidWorks, CATIA, or Siemens NX; familiarity with PDM/PLM systems a plus.
