Job description

Threadlock Precision is a rapidly growing engineered component manufacturing organization serving leading aerospace and defense customers, including OEMs and Tier 1/Tier 2 suppliers. Backed by strong financial support and positioned for continued expansion, we are investing in our people, capabilities, operations, and commercial strategies to support long-term growth and meet increasing demand across complex, high-precision manufacturing programs.

We are currently hiring a Manufacturing and Process Engineer at our manufacturing/machining operation located in St. Louis, Mo. The Work We Do Matters! Our products support the defense industrial base and ensure that the men and women serving our country have reliable, high-quality equipment.

How You will Make a Difference

Reporting to our Engineering Manager, you will have the unique opportunity to help shape and scale a growing manufacturing platform at a critical stage of expansion.

We are looking for engineers who are problem solvers, critical thinkers, and difference makers. In this role, you will help build and improve the manufacturing processes that enable us to consistently meet the quality, delivery, and performance expectations of our aerospace and defense customers. You will work closely with the people closest to the work to identify opportunities, solve problems, improve processes, and implement practical solutions that strengthen our operations and support continued growth.

Core Responsibilities

Product and Process Development & Ownership

• Partner and collaborate with customers on product design and manufacturability.
• Develop, document, and improve CNC machining and manufacturing processes for new and existing work, including routing, setup strategy, tooling requirements, machining methods, and production readiness.
• Translate engineering drawings, models, customer requirements, and GD&T into practical manufacturing plans that support quality, repeatability, delivery, and cost targets.
• Partner with CNC machinists, operators, quality, and production leadership during setup, first-piece, first-article, production launch, and ongoing production support activities.

Process Optimization & Continuous Improvement

• Identify and implement improvements that increase throughput, improve repeatability, reduce variation, and strengthen overall CNC process performance.
• Optimize cycle time, tool life, machine utilization, setup time, operator efficiency, and production flow while reducing scrap, rework, non-value-added activity, and recurring production constraints.

Problem Solving

• Identify root causes, improve process stability, and help remove barriers to CNC Machining, quality, delivery, and throughput.

Quality, Documentation & Compliance

• Create and maintain manufacturing work instructions, setup sheets, tooling lists, process instructions, and controlled documentation to support consistent execution.
• Collaborate with Quality to resolve dimensional issues, repeatability concerns, inspection gaps, and customer requirement concerns while supporting AS9100 and internal quality requirements.

Basic (required) Qualifications

• Bachelor’s degree in engineering with at least 1 year (internships can be included) of manufacturing or process engineering experience within precision machining.
