Mold Flow Engineer - contract

Main purpose of the job

As a Mold Flow Engineer at Artifex Interior Systems, you will deliver Moldflow simulation in support of plastic injection-moulded component and tooling design across the product lifecycle.

The role supports simulation-led decision-making from early concept through to approved off-tool parts, contributing to reduced tooling risk, improved quality and robust industrialisation outcomes.

Main missions and results

• Perform Moldflow simulations (Fill, Pack, Warp, Cooling and Fibre Orientation) to support component and tooling design.

• Create high-quality meshed models using appropriate mesh technologies and refinement strategies to maximise simulation accuracy.

• Build representative Moldflow models incorporating cooling channels, inserts, feed systems, injection pressure profiles and other tool-specific data where required.

• Analyse Mold Flow results and provide clear, actionable engineering guidance to design, tooling and production teams.

• Identify moulding and tooling risks using Mold Flow analysis, including ‘what-if’ and sensitivity studies, and define mitigation actions.

• Act as a technical resource for colleagues by supporting understanding and effective use of Mold Flow outputs.

• Optimise gating strategies, runner layouts, cooling circuits, cycle times and overall tool performance using simulation.

• Support Design for Manufacture (DFM) reviews for new and existing plastic components.

• Collaborate with tooling engineers on mould design, venting strategy, material selection and processing parameters.

• Liaise with engineering and design teams, attending design reviews to advise on Mold Flow analysis requirements throughout development phases.

• Produce technical reports and presentation material to communicate analysis results to internal stakeholders and, where required, customers.

• Participate in tooling GA reviews and mould trials, collecting process data to correlate simulation predictions with actual tool performance.

• Support root-cause analysis of moulding defects using Mold Flow outputs and in-plant validation data.

• Develop and maintain Moldflow best practices, libraries, templates and workflows to drive continuous improvement.

• Manage multiple Mold Flow activities in parallel, ensuring timely delivery aligned to programme milestones.

• Work with suppliers, toolmakers and moulding partners to validate simulation assumptions and align on technical standards.

Preferred skills and experience

• Proven experience performing Moldflow simulation for injection-moulded plastic components.

• Ability to create fully meshed part and tool models, including complex tool features where required.

• Solid understanding of plastic component design, mould tool design and injection-moulding processes.

• Strong knowledge of thermoplastics, fibre-filled materials, shrinkage modelling and warpage control.

• Excellent analytical and problem-solving capability.

• Clear written and verbal communication skills, able to explain complex Mold Flow results to non-specialist audiences.

• Ability to manage multiple simulation tasks and work collaboratively within cross-functional engineering teams.

• Experience working with toolmakers or injection-moulding suppliers.

Desirable

• Experience correlating simulation outputs with mould trial results.

• Familiarity with DOE methods, optimisation studies or additional CAE tools.

• Strong proficiency in Autodesk Moldflow Insight

• Degree (or equivalent experience) in Mechanical, Plastics, Manufacturing or Materials Engineering.

• Knowledge of GD&T, DFM, DFA or tolerance analysis.
