Senior Additive Manufacturing Engineer; WAAM

Position: Senior Additive Manufacturing Engineer (WAAM)
Location: Ampthill

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.

Key Responsibilities

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).Key Skills & Competencies

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.
Required skills, qualifications and experience

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.
