Manufacturing Process Engineer – Nutraceutical Production

Full-Time, On-Site

Springfield, Ohio

Starting pay $62,000.00 - $79,000.00 per year based on experience - quick growth opportunity position

Relocation assistance may be considered for highly qualified candidates with significant nutraceutical manufacturing experience.

All-In Nutritionals is a fast-growing, vertically integrated nutraceutical manufacturing company based in Springfield, Ohio. We formulate, manufacture, test, package, and ship over 150 unique dietary supplements and wellness product in-house for both our own brands and contract manufacturing partners across the country.

As an NSF-certified, cGMP-compliant facility audited to FDA 21 CFR Part 111 standards, we are committed to high-performance manufacturing, quality, innovation, and operational excellence. Our team operates in a dynamic, entrepreneurial environment where speed, quality, and continuous improvement matter every single day.

We are entering a major growth phase, expanding production capacity, implementing advanced systems, and scaling both our internal brands and private label partnerships. This is an opportunity to join a company where your engineering impact will be visible, measurable, and mission-critical.

If you thrive in a hands-on manufacturing environment and want to help build scalable systems inside a rapidly growing nutraceutical operation, this role offers the chance to make a real difference. All-In Nutritionals is seeking a hands-on Manufacturing Process Engineer to drive production efficiency, equipment optimization, and scalable product execution within our nutraceutical manufacturing facility.

This is a production-focused engineering role centered on how formulations move through commercial-scale manufacturing equipment. The primary responsibility of this position is ensuring that new and existing dietary supplement products flow efficiently, consistently, and reliably through blending, encapsulation, powder filling, liquid processing, gummy, and packaging systems.

This role works alongside R&D and Quality teams but is fundamentally process-engineering driven. While the position may assist in pilot batching and scale-up validation, it is not a lab-based R&D role. It is a manufacturing execution and optimization role.

The ideal candidate has hands-on experience working with commercial nutraceutical manufacturing equipment and understands how formulation behavior directly impacts machinery performance, throughput, and product quality.

• Process Engineering & Equipment Optimization
• Serve as the primary process engineering lead for new and existing formulations entering production
• Evaluate how formulas behave during blending, encapsulation, powder filling, liquid processing, and other production operations
• Run pilot and validation batches prior to full production runs
• Adjust, optimize, and dial in machinery settings to improve throughput, consistency, and repeatability
• Identify and eliminate production bottlenecks
• Improve line efficiency, material flow, and changeover performance
• Ensure processes are stable, repeatable, and scalable before full commercial production
• Remain engaged during initial production runs of new products until fully validated
• Work directly on the production floor to troubleshoot equipment, formulation, or mechanical performance challenges
• Continuously evaluate production data to improve output and reduce waste

• Collaborate with R&D during product development to ensure formulas are designed for manufacturability
• Provide feedback regarding flowability, compressibility, blending performance, and equipment compatibility
• Assist with scale-up validation and process refinement
• Support Quality in maintaining NSF cGMP compliance and documentation standards
• Help refine SOPs to reflect validated, production-ready processes

• Develop clear, step-by-step process documentation for manufacturing execution
• Enter and refine formula and process workflows in Mar-Kov ERP
• Ensure all process parameters are documented for repeatability,…
