Robotics Hardware Engineer – Mechanical Systems

Field AI is transforming how robots interact with the real world. We are building risk-aware, reliable, and field-ready AI systems that address the most complex challenges in robotics, unlocking the full potential of embodied intelligence. We go beyond typical data-driven approaches or pure transformer-based architectures, and are charting a new course, with already-globally-deployed solutions delivering real-world results and rapidly improving models through real-field applications.

Hardware Team at Field AI develops perception and compute payloads that power autonomous robotics systems in complex real world environments. Our work spans the full hardware stack designing and integrating sensing systems (LiDAR, camera, TOF, IMU, GPS), embedded compute (CPUs, GPUs, microcontrollers, Linux, ROS), electrical systems (power distribution, communication), and mechanical components (structures, thermal regulation, ingress protection). The team focuses on both development (research, design, prototyping, testing) and operations (production, testing, QA, debugging).

We’re a small, fast-moving team, and we care deeply about improving: core capabilities, system reliability, system scalability. As a growing team we are also building operational systems and procedures from the ground up.

As a Mechanical Engineer on the Hardware Team at Field AI, you will contribute to the design and implementation of mechanical systems that house and support sensing and compute platforms in real-world environments. From ruggedized enclosures to thermal management to manufacturability, your work will be critical to ensuring our systems operate reliably in the field. Responsibilities may span the full lifecycle from CAD through production to field support.

You will collaborate closely with electrical, compute, and systems engineers to build tightly integrated solutions ready for deployment in challenging field environments. Additionally while your focus will be on mechanical systems you will likely contribute across all hardware domains.

• 1. Mechanical System Design
• Structures: Design and model mechanical structures including external enclosures, internal compute frames, and load-bearing chassis.
• Mounts: Design and validate robust sensor mounts, payload attachment points, and mechanical interfaces.
• Ingress Protection: Implement IP-rated solutions with gaskets, seals, membranes, and coatings to meet water/dust ingress standards.
• Thermal Management: Incorporate thermal mitigation strategies such as fans, heat sinks, conductive paths, and airflow guides.
• Mass & Volume Budgets: Ensure adherence to payload constraints, including tight volumetric envelopes and weight limitations.

• 2. Mechanical System Implementation
• CAD & Simulation: Build detailed Solid Works CAD assemblies. Run FEA and thermal simulations to validate strength, durability, and heat dissipation.
• Material & Component Selection: Choose materials and components to meet mass, strength, thermal, and manufacturability constraints.
• Design for Production: Apply DFM, DFA, DFS principles throughout the design lifecycle.
• System Testing: Conduct mechanical load testing (shock, vibration), thermal validation, ingress tests, and sensor alignment assessments.
• Prototyping: Rapidly iterate on prototypes for fit checks, thermal evaluations, and integration trials.
• Documentation & Budgets: Generate mechanical drawings, GD&T annotations, BOMs, and assembly instructions for fabrication and QA. Manage weight, volume, and thermal budgets.

• 3. Mechanical System Production & Servicing
• Build: Work with vendors and contract manufacturers to procure mechanical hardware. Develop QA checks for incoming units. Support payload integration and scaling.
