Intermediate Control System Field Service Engineer

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 labour 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, 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

At 4AG Robotics, we build intelligent robots that harvest mushrooms — and we're solving one of agriculture's biggest challenges: labour shortages. As we scale rapidly, we're looking for an Intermediate Control System Field Service Engineer to join our growing Mechatronics Team. Based in Monaghan, Ireland, this role is your chance to work at the cutting edge of robotics in a high-impact industry, building systems that support a more sustainable food future.

What You'll Do

You’ll be supporting the deployment of our robotic and automation systems in the field where the magic happens. Working closely with a cross-functional team of engineers and technologists, you’ll:

• Troubleshoot PLC code (Structured Text) for industrial automation systems.
• Utilize a variety of connected platforms & diagnostics tools to provide remote support to customers and our team on the farm.
• Troubleshoot and resolve electrical, software, and mechanical integration issues.
• Evaluate customer sites in order to plan the layout and installation of robotic harvesting equipment.
• Lead system commissioning both locally and at customer sites internationally.
• Support the design and review of control panels, schematics, and system layouts.
• Collaborate closely with mechanical, electrical, and software teams to improve system performance.
• Contribute to the development and testing of new robot features.

What Success Looks Like 

You’re able to take a system from concept to commissioning- independently and with confidence. You contribute ideas, fix problems before they escalate, and help the team move faster and smarter. You’re hands-on, detail-oriented, and genuinely excited about pushing the boundaries of what robotics can do in agriculture. Customers and teammates know they can count on you.

Why This Role Matters

Our robots operate in demanding agricultural environments, and their success depends on the seamless integration of hardware, software, and control systems. As we scale up internationally, your expertise ensures our platforms are reliable, efficient, and ready for the world. This role is a cornerstone in turning innovation into real-world impact, and directly shapes the future of food.

What You Bring

• Bachelor’s degree in Mechatronics, Electrical, or related Engineering field
• Minimum 5 years’ experience in automation, with experience working in a production environment.
• PLC programming experience (Structured Text and Ladder Logic), ideally with B&R systems
• Strong motion control skills — servo tuning, path planning, kinematics
• Hands-on experience programming and integrating robotic arms (SCARA, 6-axis, gantry)
• Experienced with control panel hardware, industrial sensors, safety PLCs, low voltage power distribution, and servo drives
• Understanding of mechanical systems, pneumatic circuits, and kinematics
• Strong troubleshooting skills and field commissioning experience
• Self-starter attitude with a collaborative, solutions-focused mindset
• Ability to travel internationally for deployments

Perks and Benefits

• Competitive salary and performance-based bonuses
• Comprehensive health, dental, and vision coverage
• Annual healthcare spending account
• Flexible work hours and no micromanagement — we focus on outcomes, not timesheets
• A fun, collaborative, and supportive team environment
• Professional development and mentorship opportunities

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.
