About Us

River City Machine, LLC is a growing, high-precision CNC machine shop specializing in engine components for automotive and industrial markets. Our facility includes 5-axis machining centers, 9-axis mill-turn machines, and a Landis/Fives CNC Camshaft Grinder.

We are a division of RCD Performance, LLC — a leader in performance aftermarket products for the diesel industry. Unlike most machine shops, we design, test, and market our products directly to consumers, which gives us immediate feedback for design improvements and allows our engineers to see the real-world impact of their work.

We are currently investing $5 million in a new, fully air-conditioned facility, making this the perfect time to join our team and grow with us.

The Opportunity

We are looking for a CNC Manufacturing Engineer with strong CNC programming and setup skills. In this role, you’ll be the bridge between design and production — programming our advanced machines, designing fixturing, and ensuring smooth handoff to operators.

If you’re passionate about precision machining, process improvement, and contributing to products that real customers use and love, this is your chance to work with cutting-edge technology and make a real impact.

What You’ll Do

• Program and optimize CNC operations for 5-axis, 9-axis, and grinding equipment using CAM software (Mastercam, Siemens NX).
• Interpret blueprints and apply GD&T to achieve accuracy within tight tolerances.
• Design and implement fixturing solutions for complex engine parts.
• Set up CNC machines, configure Fanuc controls, and verify tool paths.
• Partner with operators to troubleshoot and ensure seamless production runs.
• Continuously improve machining processes to reduce cycle times and boost productivity.
• Maintain setup sheets, programming documentation, and repeatable processes.
• Collaborate with design teams to integrate direct customer feedback into new products.

What We’re Looking For

• Bachelor’s degree in Manufacturing/Mechanical Engineering OR equivalent hands-on experience.
• 3 years of CNC programming & setup in a production environment.
• Strong experience with Fanuc controls and multi-axis machining.
• Proficiency with CAM software (Mastercam, Siemens NX, Fusion 360) and CAD (SolidWorks, AutoCAD).
• Ability to design and implement custom fixturing.
• Strong problem-solving, attention to detail, and teamwork skills.
• Experience with camshaft grinding equipment is a plus.

Why Join Us?

• Work with a parent company (RCD Performance, LLC) that is a recognized leader in diesel aftermarket performance products.
• Be part of a team that designs, tests, and sells directly to consumers — and see your work make an immediate difference.
• $5 million expansion and state-of-the-art, air-conditioned facility.
• Hands-on experience with cutting-edge CNC technology.
• Competitive pay, overtime opportunities, and a tool allowance.
• Career growth potential in a company that values innovation and expertise.
• Join a growing team in East Peoria’s thriving manufacturing hub.
