Liam Douglas

MECHANICAL ENGINEER

Skills Overview

Liam is a mechatronics design engineer with a strong foundation in product design, automation, and electromechanical system integration. His career was established in the biotechnology sector, where he designed novel wound-care products, built product testing equipment, and created bespoke machinery to automate manufacturing processes. Liam is a versatile and adaptable engineer who works effectively both independently and within multidisciplinary teams. He brings a cross-disciplinary approach to problem-solving across mechanical, electrical, and software systems, supported by hands-on experience in rapid prototyping, design for manufacture, CNC machining, fabrication, and assembly.

• MACHINE DESIGN – Liam has experience designing machinery for polymer braiding, silicone catheter drilling, organic tissue lamination and blanking, and rapid drying of material handling equipment. His experience spans custom part design, enclosures and guarding, motion systems, pneumatics, motors, sensors and actuators, and robotic end effectors. The electromechanical engineering challenges inherent in machine design fuel Liam’s passion for creating innovative machinery.
• AUTOMATION & CONTROLS – Liam has designed, fabricated, and commissioned electrical control panels for industrial machinery. He has also developed computer vision systems for assessing product quality and categorising raw materials. He is proficient in programming PLCs and HMIs to provide intuitive, user-friendly control of industrial equipment. Additionally, Liam has created automated test equipment for evaluating ultrasonically welded components and developed software to control chemical mixing chambers.
• MECHANICAL DESIGN – Liam has designed and tested a variety of mechanical components for medical devices and machinery applications. He has a strong understanding of design for manufacture, with extensive experience creating parts for 3D printing, 2D cutting (laser, water, and plasma), CNC machining, turning, and injection moulding. Liam has conducted failure analysis of critical components using FEA (Finite Element Analysis) to ensure designs are optimised before committing time and budget to complex machining projects. He enjoys getting hands-on with his work, including rapid prototyping, using CAM tools for CNC machining, fabrication, and assembly.
• MATERIALS SELECTION – Liam has extensive knowledge of plastics and metals commonly used in the medical industry. He is capable of designing equipment with biocompatible materials and understands material costing, failure modes, and optimal applications. Liam has designed complex lamination tooling by leveraging his understanding of stainless steel grades and how they affect machinability, cost, cleanability, wear resistance, and potential product risks through failure analysis.
• MEDICAL DEVICES – Liam has worked on a range of medical devices under an ISO 13485 quality management system, gaining full exposure to the product lifecycle across teams in product development, process development, and manufacturing. He understands the importance of end-user focused design, design controls, testing, validation, and maintaining high manufacturing standards. Products he has contributed to include dead-space management systems, bio-absorbable fluid draining conduits, silicone catheters, and organic bio-scaffolds.
• ENGINEERING DOCUMENTATION – Liam is experienced in producing a wide range of engineering documentation, including work instructions, standard operating procedures, engineering drawings, pneumatic P&ID diagrams, and bills of materials (BOMs). He also prepares technical reports, validation and commissioning documentation, and contributes to specialised documents such as FMEAs (Failure Mode and Effects Analysis).
