About Us

At 4AG Robotics, we’re wired for solving tough problems - and mushroom harvesting with robots is about as tough as it gets. We solve the critical labor shortage for farms by building robots that pick, trim and pack mushrooms. 

We are a team of builders that like to move fast and embrace the uncertain process of innovation - because every breakthrough comes with a few mistakes along the way. Our robots are already working on six of the world’s largest mushroom farms - and this is just the beginning.  

 
If you love tech, thrive on innovation, and have a passion for building and bringing it to life in the real world in a
commercial space, you’ll find your spot here. Join us and help reshape the future of farming with grit, brains, and a team that actually gets things done. 

The Opportunity

We’re looking for a skilled and hands-on Machinist and Fabricator to join our R&D team, where innovation moves fast and every part matters. This role offers the chance to contribute directly to the creation of custom components for cutting-edge prototypes in a dynamic environment. You'll work alongside engineers and technicians who are passionate about precision, problem-solving, and building what’s next in agricultural robotics.

What You’ll Do

• Set up and operate manual and CNC equipment such as mills, lathes, saws, and grinders
• Machine and fabricate precision parts based on technical drawings, CAD models, and blueprints
• Perform MIG, TIG, and/or stick welding on materials including aluminum, steel, and stainless
• Create custom brackets, frames, and assemblies using fabrication tools like brakes, rollers, and shears
• Inspect completed work to verify dimensional accuracy and quality standards
• Maintain, troubleshoot, and calibrate shop tools and equipment for peak performance
• Collaborate closely with engineering and mechanical design teams to refine manufacturability
• Track material usage, support inventory management, and report shortages
• Ensure safety protocols are followed and help maintain a clean, organized workspace
• Contribute ideas to continuously improve workflows and shop processes

What Success Looks Like

• High-quality, precise parts are consistently delivered on time to support fast-paced prototyping needs
• You proactively identify and solve fabrication or design challenges in collaboration with the team
• Equipment is well-maintained, safe, and ready to go-downtime is minimal
• You contribute to process improvements that increase efficiency and reduce rework
• You’re a go-to person for turning ideas into tangible, working components

What You Bring

• Red Seal certification in Machining, Metal Fabrication, or equivalent trade experience (preferred)
• 3+ years of machining and fabrication experience, ideally in prototyping or custom manufacturing
• Proficiency with both manual and CNC machining techniques and welding processes
• Strong ability to interpret technical drawings and use precision measuring tools (e.g., callipers, micrometers)
• Familiarity with a wide range of materials, tolerances, and fabrication methods
• Experience with CAD/CAM software is a plus
• A keen eye for detail, a strong work ethic, and a collaborative spirit
• Physically able to lift 50 lbs and stand for extended periods

Why This Role Matters

As a Machinist and Fabricator, your work brings our ideas to life. Whether it’s the first version of a new part or a precision fix to an existing one, your contributions are essential to building, testing, and improving the technology that powers our robots. You are the link between design and execution-and your craftsmanship helps drive innovation forward.

What We Believe

If you’re the type who likes to take chances, move at speed, and see your ideas come to life, you’ll feel right at home here. At 4AG, we’re not big on rules for the sake of rules - we’d rather trust you to make bold calls, keep it real with your team, and turn imagination into something game-changing. This isn’t a place to play it safe; it’s a place to build, break, fix, and build again - while having a great time doing it.
