Sigil Partners; Cincinnati (OH); On-site; USD 90,000 - 120,000; Full time

Job summary

Sigil Partners is seeking a hands-on Manufacturing Engineering Supervisor in Cincinnati to run end-to-end projects and keep the engineering function moving when the senior manager is unavailable.

You will program, fixtures, tool paths, and release work through gate reviews while supporting machining, quality, and operations on-site. Strong NX CAM and CNC shop-floor background are required, with prior NPI experience and lean leadership a plus.

Qualifications

• Bachelor’s in Mechanical, Manufacturing, or Industrial Engineering or equivalent practical experience.
• Hands-on CNC/machining experience required.
• Experience taking from print to production with minimal supervision.

Responsibilities

• Lead end-to-end manufacturing engineering projects (NX CAM programming, fixture design, tooling).
• Support large-part machining: multi-axis milling and large horizontal boring mills up to ~68" dia.
• Introduce new products and optimize legacy programs with improved tooling and tool paths.
• Daily prioritization of engineering work, shop support, and urgent troubleshooting.
• Conduct gate reviews with engineering, methods, and quality before floor release.
• Provide on-site coverage for the Senior Manager when needed.
• Collaborate with sister sites to share resources and optimize schedules.

Job description

Our company produces complex, mission-critical machined parts for power generation, aerospace, defense, and oil & gas. The Cincinnati site is scaling fast — power-generation demand is already up roughly 4x heading into Q1, with more growth expected through 2028.

About the Role

We need a hands-on manufacturing engineering supervisor who can run jobs end-to-end and keep the engineering function moving when the senior manager is unavailable. This is not a desk-only methods role. You will program, design fixtures, set tool paths, release work through gate reviews, and be the first call when a machine or NPI is in trouble. You report directly to the Senior Manufacturing Engineering Manager and work across machining, quality, and operations.

Responsibilities

• Full-project manufacturing engineering: NX CAM programming, fixture design, tooling, work instructions, and process prove-out
• Large-part machining support — multi-axis milling and large horizontal boring mills (parts up to ~68" diameter)
• New product introduction and optimization of long-running legacy programs with newer tooling and better tool paths
• Daily prioritization of engineering work, shop support, and urgent troubleshooting
• Gate reviews with engineering, methods, and quality before jobs hit the floor
• Acting coverage for the Senior Manager during planned absence (first week of transition on-site; manager remains reachable by phone/Teams after that)
• Collaboration with sister sites when resources need to be borrowed or shared

Qualifications

• Bachelor’s in Mechanical, Manufacturing, or Industrial Engineering — or equivalent practical experience. Shop-plus-CAM background will beat a degree with no machine time.

Required Skills

• Strong NX CAD/CAM programming experience (tool paths and process, not modeling-only)
• Hands-on CNC / metalworking background — shop-floor origin is a plus
• Proven ability to take a job from print to production without a specialist sitting next to you
• Experience with large, complex metal parts and multi-axis or horizontal boring work
• Ability to work on-site, first shift, ~50-hour weeks, with occasional weekend coverage for urgent issues
• Comfort leading work and people in a lean team (no dedicated methods or applications engineers today)

Preferred Skills

• Started as a machinist or programmer and moved into engineering
• NPI experience in a high-mix, low-to-medium volume shop
• Track record improving old programs for cycle time, tool life, or scrap
• Lean / continuous-improvement and clear process documentation habitsWillingness to relocate to the Cincinnati metro if not already local
