Manufacturing Engineer

Position Summary 

603 Manufacturing is growing, and we are looking for a hands-on, detail-driven NPI / Manufacturing Engineer who thrives on turning complex, high-reliability builds into clean, repeatable, audit-ready processes. This role is especially critical as we support customers in the space and aerospace sectors, where documentation, traceability, and process control are non-negotiable. If you get fired up about transforming first builds into flight-ready production systems, this role is for you.

What You’ll Do

Lead New Product Introduction (NPI)

• Own the manufacturing ramp-up for new cable and electro-mechanical assemblies
• Translate engineering drawings, specifications, and customer requirements into production-ready processes
• Support and fully document first piece builds from prototype through production release
• Ensure builds meet space and aerospace level workmanship and documentation standards

Develop Flight-Ready Work Instructions

• Create clear, visual, step-by-step work instructions for complex cable assemblies
• Standardize documentation across programs to meet customer and regulatory expectations
• Build controlled, revision-managed documentation packages
• Incorporate inspection criteria, torque values, crimp specifications, test procedures, and traceability requirements

Space and Aerospace Compliance

• Interpret and implement customer flow-down requirements
• Ensure compliance with applicable standards such as:
  • IPC/WHMA-A-620, Space Addendum preferred
  • NASA workmanship standards where applicable
  • AS9100 principles and documentation rigor
• Establish full material traceability and lot control processes
• Support first article inspections and customer audits
• Build processes that are repeatable, traceable, and audit-ready 

First Piece and Process Development

• Capture photos, tooling setups, fixturing, inspection points, and lessons learned during first builds
• Identify risk areas early including handling, routing, strain relief, testing, and labeling
• Define quality gates and inspection checkpoints
• Convert tribal knowledge into controlled documentation

Standardization and Continuous Improvement

• Develop scalable templates for cable assembly documentation
• Drive consistency across programs and operators
• Improve throughput while maintaining zero-defect expectations
• Reduce variability in high reliability builds

What Makes You a Great Fit

• 5 or more years in manufacturing engineering, NPI, or process engineering
• Direct experience supporting space, aerospace, or other high-reliability customers
• Strong understanding of:
  • IPC/WHMA-A-620, Space Addendum strongly preferred
  • First Article Inspection, AS9102 experience a plus
  • Configuration control and revision management
  • Lot traceability and material control systems
• Experience building processes that withstand customer audits
• Comfortable on the production floor. This is not a desk-only role.
• Process-driven, detail-focused, and quality-first mindset

Bonus Points If You Have

• Experience supporting NASA, commercial space, or defense programs
• Experience working in an AS9100 environment
• Familiarity with controlled documentation systems such as PLM, ERP, or QMS
• Lean or Six Sigma background
• Experience building documentation systems from scratch

What Success Looks Like

• New space programs transition from first article to stable production smoothly
• Documentation passes audits without scrambling
• Full traceability exists from raw material to finished assembly
• Operators have clear, easy-to-follow instructions
• Builds are consistent, repeatable, and flight-ready

Why 603 Manufacturing?
