Senior Additive Manufacturing Engineer; WAAM

About the Role

Join our Production Operations Engineering Team as a Manufacturing Engineer!

The Manufacturing Engineer (WAAM Bias) designs, implements, and optimizes large-scale Wire Arc Additive Manufacturing processes for aerospace components. This role focuses on the development of processes for complex, near-net-shape metallic structures from design to production, ensuring strict compliance with aviation quality and safety standards.

• Process Development:
  Establish, validate, and optimize WAAM deposition parameters (current, voltage, travel speed, shielding gas flow) for aerospace alloys like Titanium, Inconel, and Aluminium.
• Path Planning & Simulation:
  Utilize specialized additive software to generate, simulate, and optimize multi-axis robot/CNC deposition paths to prevent collisions and minimize thermal distortion.
• Thermal Management:
  Design and execute thermal control strategies, including inter-pass temperature monitoring and in process cooling, to manage residual stress and microstructural integrity.
• NPI Support:
  Lead New Product Introduction (NPI) by transforming aerospace CAD models into WAAM-optimized, near-net-shape geometries ready for post-process machining.
• Equipment Integration:
  Program, configure, and maintain integrated WAAM cells, including robotic manipulators (ABB), power sources (Fronius) and environmental enclosures.
• Quality &
  
  Qualification:
  
  Ensure all manufacturing processes conform to aerospace standards such as AS9100 and emerging additive manufacturing regulations (e.g., ASTM F42, SAE AMS
  7039).

• Additive Software:
  High proficiency in WAAM-specific slicing and path-generation software.
• Robotics & Automation:
  Competence in programming multi-axis industrial robots and integrating sensor feedback loops for real-time process monitoring.
• Aerospace Metallurgy:
  Deep understanding of solidification mechanics, phase transformations, and defect generation (porosity, cracking) in wire-fed arc deposition.
• Subtractive Integration:
  Strong knowledge of how WAAM near-net shapes interface with subsequent precision CNC machining operations.
• Root Cause Analysis:
  Mastery of problem-solving frameworks (8D, FMEA, 5 Whys) to troubleshoot deposition anomalies and microstructural defects.

• Good working knowledge of CNC Machining, turning and Milling up to 5 axis with Cam software experience or working knowledge of WAAM / Additive Manufacturing.
• Knowledge of Lean Manufacturing, Six Sigma and quality improvement tools.
• Experience with CAD software for generating 2D technical drawings.
• Solid understanding of MRP systems and experience managing BOMs and routings in SAP (or similar ERP systems).
• Hyper Mill Cam experience would be a advantage.
• Proven ability to drive cultural and process change, improving efficiency and quality.
• A collaborative mindset with a passion for continuous improvement.
• Education:
  
  Degree or Master’s in Manufacturing, Materials Science, Aerospace, or Mechanical Engineering (a PhD or research focus heavily centered on WAAM/DED is highly desirable).
• Experience:
  
  Minimum 3 years of hands‑on experience in Directed Energy Deposition (DED), specifically Wire Arc Additive Manufacturing, within a high-integrity engineering environment.
• Industry Background:
  Prior experience in aerospace, space‑launch systems, or defence manufacturing is required.
