Engineer Sr

Donaldson is committed to solving the world’s most complex filtration challenges. Together, we make cool things. As an established technology and innovation leader, we are continuously evolving to meet the filtration needs of our changing world. Join a culture of collaboration and innovation that matters and a chance to learn, effect change, and make meaningful contributions at work and in communities. ​

We are seeking a highly motivated Engineer ll / Engineer Sr.  - Injection Molding simulation to join our Engineering Simulations function within the Global Technical (GT) Group at Donaldson Inc. 

In this role, you will be instrumental in driving simulation-driven design and process optimization for injection molded filtration products. You will apply advanced CAE tools and scientific molding principles to improve moldability, product quality, and manufacturing robustness, while reducing development cycle time.

You will work in a globally integrated environment, collaborating with engineering, tooling, and sourcing teams across North America, EMEA, and APAC, influencing both current production programs and next-generation product platforms.

Key Responsibilities: 

• Lead injection molding process simulations (filling, packing, cooling, warpage) to support product and tooling design decisions
• Perform analytical modeling using Sigmasoft (preferred) or equivalent tools (e.g., Moldflow)
• Drive Design for Manufacturability (DFM) by identifying risks related to moldability, defects, and process variability
• Execute Design of Experiments (DOE) and optimization studies to define robust processing windows
• Collaborate with tooling, manufacturing, and sourcing teams to develop and validate tooling strategies
• Investigate and resolve part quality issues using simulation insights and correlation with molding process parameters.
• Correlate simulation results with physical trials and molded part data to improve model fidelity
• Develop standardized workflows, automation scripts, and scalable simulation practices
• Prepare and present technical reports and recommendations to cross-functional stakeholders
• Contribute to structural/design evaluations of molded components in collaboration with CAE teams

Education Qualification:

• B.E./B.Tech or M.E./M.Tech in Plastics, Mechanical, or Manufacturing Engineering (Masters preferred).

Technical Competence & Skills:

• Solid foundation in the injection molding process physics and plastic part design
• Hands on experience with Sigmasoft /Moldflow Sigmasoft is preferred.
• Knowledge of scientific molding principles and practical exposure to molding machines and auxiliaries
• Working knowledge of DOE, multi-objective optimization techniques and surrogate modeling approaches for part design exploration and process improvement.
• Familiarity with GD&T for engineering drawing interpretation.
• Experience with CAD tools (NX preferred) for modeling and geometry preparation.
• Exposure to Ansys or structural CAE tools for durability/strength analysis (added advantage)
• Understanding of HPC/distributed computing environments for large scale simulation execution.

Leadership Competence:

• Strong ownership mindset with ability to drive problems to closure
• Effective communicator with the ability to translate simulation insights into actionable decisions
• Proven ability to collaborate across global, cross-functional teams
• Comfortable working across time zones in a global engineering environment

Relevant Experience:

• 5 -10 years of experience working in Injection molding simulation (Sigmasoft preferred).

Others (% of travel, language, etc.):

• 10-20% travel based on the business needs
