John Mark R.

Experience

• R&D Design Engineer Conflux Technology · Full-time Feb 2025 – Jul 2025 5 mos Waurn Ponds, VIC, Australia • Supported the R&D team in LPBF (Laser Powder Bed Fusion) manufacturing capability development, including DFAM-oriented CAD, thin-walled structure design, and fixture/test rig design to support material and laser parameter development.
  • Enabled production readiness for heat exchangers supplied to motorsport and aerospace clients by ensuring manufacturing processes were optimised for quality and repeatability.
  • Designed a custom in-house test rig, integrating sensors, PLCs, and data acquisition systems; completed the design phase and prepared for manufacturing and procurement to accelerate validation cycles.
  • Conducted airflow and pressure drop testing on heat exchangers using in-house rigs to assess and refine performance.
  • Oversaw AS9100D and ISO 9001 quality systems, ensuring smooth compliance, full traceability, and production readiness through 3DExperience CATIA (BOM, PDM, PLM, EDMS) and Monday.com
• Mechaniacal Design Engineer (Research & Development) Quantum Servo Pumping Technologies · Full-time Jun 2018 – Feb 2025 6 yrs 8 mos Campbellfield, VIC, Australia • Led the end-to-end design, prototyping, testing, and production release of components, mechanical subsystems, and fully integrated products — notably the Actuator Assemblies and High-Pressure ends of Electric Servo Pumps (ESP)
  
  • Utilised CAD (SolidWorks), FEA, tolerance analysis, and reverse engineering to engineer components capable of withstanding ultra-high operating pressures up to 87,000 psi/6000 Bar, ensuring reliability under extreme service conditions.
  
  • Selected and integrated advanced materials (high-strength alloys, engineering plastics) — applying material science principles directly transferable to composite selection and layup strategies.
  
  • Partnered with in-house and external manufacturing teams to transition designs from CAD to production, aligning DFMA principles with factory capabilities to streamline assembly handover.
  
  • Designed and prepared test tooling and jigs with integrated sensors and data acquisition systems to mirror performance verification processes used in composites testing.
  
  • Maintained compliance with CE, UL, ASME, OH&S, and IECEx/Atex standards, ensuring rigorous design documentation and traceability via Aras PLM and Microsoft Dynamics.
  
  • Mentored production engineers (QSPT Thailand) and technicians, fostering collaborative problem-solving and knowledge transfer across teams.
  
  Selected Achievements:
  • Designed patented ultra-high-pressure seal assembly (AU 2021201775B2) and novel one-way valve (US20240301960A1, AU2023901862 – pending).
  • Delivered five complete product lines with Quantum SPT — from prototype to market release — incorporating advanced materials (high-strength alloys, engineered plastics) and precision manufacturing processes, achieving zero non-conformance reports at launch.
  • Bridged engineering design and manufacturing by implementing DFMA reviews and rapid feedback loops between the Australian design office and the production team in Thailand. Supported handover by creating initial assembly instructions, specifying tooling, and managing BOMs, reducing prototype-to-production iteration cycles by 30% and improving product reliability in field testing
• Mechanical Design Engineer/Production Engineer Techni Waterjet · Full-time Nov 2016 – Jun 2018 1 yrs 7 mos Campbellfield, VIC, Australia *Same entity as Quantum Servo Pumping Technologies, but split into two entities, waterjet business was acquired by GMM, and later, Biesse
  • Designed waterjet cutting machine systems and electric servo pumps using SolidWorks and AutoCAD.
  • Collaborated with manufacturing teams and clients to develop installation layouts that balanced performance with practical site constraints.
