Job summary

Hadrian is seeking a Build Engineer, Large Scale Machining to own how our largest machined parts get made, from design review through qualification and ramp to standard production. You will bridge product and Capability Engineering, translate requirements into machining processes, and set the flow for castings, forgings, plate weldments, and hull-scale structures.

You will own new product and new process introduction end-to-end, ensuring precision across multiple setups with datum schemes that

Qualifications

• 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, and translating them into build requirements.
• Strong GD&T and tolerance-stack skills across multi-setup parts, with a proven datum strategy.
• Working knowledge of large-format machining (horizontal boring mills, gantry and bridge mills, large 5-axis machining centers, and VTLs) and large-part metrology, deep enough to drive DFM and set the build flow.
• 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, including engineering change and configuration management.
• 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.

Responsibilities

• Interpret and define product requirements from customer specifications, drawings, and contract requirements, and translate them into machining requirements, critical characteristics, and inspection needs.
• Reverse engineer parts and assemblies where technical data is incomplete or legacy, to establish design intent, critical features, and a buildable sequence.
• Review models and drawings for machinability at scale, including casting stock allowance, datum structure, tolerance stack across setups, tool and probe access, and distortion risk, and drive changes before design freeze.
• Own the end-to-end machining route (rough, stress relief, semi-finish, finish, and inspection), including handoffs to weld, cladding, and assembly.
• Set the setup count, where datums are established and carried forward, and where match‑machining with mating assemblies is required.
• Define the high-level process for each operation (envelope, critical features, material condition, cycle time against rate, and inspection approach) and hand it to Capability Engineering complete and on time.
• Define lift points, handling, and part flow through the factory so rigging and logistics can plan around the part.
• Own design intent for large-part fixtures, workholding, lift fixtures, and inspection aids, partnering with Tooling Engineering on detailed design and build.
• Provide setup sheets, datum schemes, and critical‑feature intent to CNC Programming.
• Build and maintain BOM structures, work orders, and Opus work instructions in Hadrian's PLM, ERP, and MES systems, and own engineering change and configuration control as the design matures.
• Recommend make/buy decisions, write technical packages for buy parts, and own both paths when a program runs them in parallel.
• Plan and execute subscale development articles and full-scale qualification builds, including alternate-material development where it buys down risk, and own first article delivery.
• Own disposition and root cause for new‑product non‑conformances, and drive corrective action into the design, the plan, or the process.
