Mechanical Engineer-Federal

Who are We?

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.

About the Job

At FieldAI, we build autonomous robotic systems that operate in demanding, real-world environments where tight integration between hardware and software is critical. We’re looking for a Mechanical Engineer to support system and component level design, integration, and validation for our wheeled robotic platforms across both federal and commercial programs.

Mechanical Systems Role: As a Mechanical Engineer on the Federal 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.

What You'll Get to Do

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 SolidWorks 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.

•
Debug: Investigate mechanical failures, deformation, and environmental weaknesses during testing and deployments.

•
Monitor: Develop protocols for monitoring the system mechanical health and loads.

What You Have

•
Education: B.S., M.S., or Ph.D. in Mechanical Engineering, Mechatronics, or related field.

•
Experience Level: We are recruiting across a wide range of experience levels from entry level engineers to senior and staff engineers.

•
CAD Expertise: Proficient with SolidWorks or equivalent mechanical CAD platforms.

•
Thermal & Structural Analysis: Familiarity with FEA and thermal modeling tools.

•
Field-Ready Design: Experience designing hardware that survives vibration, shock, thermal cycling, and environmental exposure.

•
Manufacturing Knowledge: Experience designing for CNC, sheet metal, additive manufacturing, and assembly workflows.

•
Mechanical Systems Integration: Experience working across teams to integrate mechanical systems with compute, sensors, and power electronics.

•
Lab Skills: Comfort with mechanical debugging, thermal test setups, vibration tables, and ingress testing.

•
Cross Functional Robotic Skills: Ability to contribute electrical, sensing, and embedded computing work to deliver robust integrated systems.

What Will Set You Apart

•
Scaling: Experience taking systems from prototype to large scale production.

•
Field Environments: Experience developing systems for harsh field environments.

•
Deployed Robotics: Experience working on robotics deployed in real world settings such as autonomous vehicles, drones, or ruggedized robots.

•
Systems Level Robotics: Fluency across mechanical, electrical, and software systems.

•
Reliability Engineering: Experience designing to meet IP ratings, MIL-STD, or equivalent ruggedness standards.
