Build Engineer, Large Scale Machining

The role

You will own the manufacturing process for large machined parts including castings, forgings, and hull-scale structures. You will translate product requirements into machining requirements and manage the end-to-end build flow from design review through qualification.

What you will do

• Interpret and define product requirements from customer specifications and drawings.
• Reverse engineer parts and assemblies where technical data is incomplete.
• Review models and drawings for machinability at scale.
• Own the end-to-end machining route including rough, stress relief, semi-finish, finish, and inspection.
• Set the setup count and establish datum schemes.
• Define high-level processes for each operation.
• Define lift points, handling, and part flow through the factory.
• Own design intent for large-part fixtures, workholding, and inspection aids.
• Provide setup sheets, datum schemes, and critical-feature intent to CNC Programming.
• Build and maintain BOM structures, work orders, and work instructions in PLM, ERP, and MES systems.

Required qualifications

• 5+ years of experience in build, manufacturing, or production engineering with direct ownership of large machined parts (roughly 2 m and up, castings, forgings, or heavy weldments) from requirements t
• Bachelor’s degree in Mechanical, Manufacturing, or Industrial Engineering, or equivalent hands-on experience.
• Experience interpreting and defining product requirements from customer specifications, drawings, and contract quality clauses.
• Strong GD&T and tolerance-stack skills across multi-setup parts, with a proven datum strategy.
• Working knowledge of large-format machining and large-part metrology.
• Experience reverse engineering parts or assemblies from incomplete technical data, legacy drawings, or physical parts.
• Experience structuring BOMs, work orders, and work instructions in PLM, ERP, or MES systems.
• Proficiency in 3D CAD.
• Comfort operating hands-on on the factory floor and making sound decisions under schedule pressure.
• Able to work on-site at our [site] factory.

Nice to have

• Hands-on experience running or programming large-format machines, including reading and critiquing CNC toolpaths.
• Experience with distortion control on large parts, including stress relief sequencing, stock strategy, and thermal effects.
• Experience with difficult materials such as Monel and other nickel-copper alloys, stainless steel, dissimilar-metal joints, and cladded surfaces.
• Exposure to weld qualification (PQR/WPS) where machined features meet weld joints.
• Background in aerospace, defense, naval, or energy programs with first article and customer source inspection.
• Experience standing up a new cell or factory while the product was still in development.

Benefits

• Medical, dental, vision, and life insurance plans
• 401k
• Relocation support may be provided for certain situations
• Flexible vacation policy
• Equity
