Sr. Engineer II, R&D

Proven To Perform

From the edges of space to the bottoms of ocean, our materials are proven to perform -- and so is our team. We're hiring high performers as proven as our products. Join us.

ATI Inc. is seeking an early-career Computational Materials Scientist with a strong Ni- and/or Ti-based metallurgy background. You will develop and deploy physics-based models to accelerate alloy and process development, link thermodynamic/kinetic predictions to process simulations, and translate microstructure predictions into property outcomes for production-scale processes.

What You'll Do

• Develop and validate thermodynamic/kinetic models for Ni- and Ti-based alloys using tools such as Thermo-Calc, Pandat, and related modules (e.g., DICRA/TC-PRISMA/MatCalc equivalents) to support alloy/process design.
• Build workflows that couple CALPHAD outputs with finite element and process simulation environments (e.g., Abaqus, DEFORM) for heat treatment, forging/rolling, casting, and additive processes.
• Predict and analyze microstructure evolution (e.g., grain size, texture, precipitation, phase fractions) and link predictions to mechanical properties and product performance.
• Design and execute computational and physical experiments (DoE) in both lab and production environments, comparing model results with experimental data, and iterating for accuracy and robustness.
• Develop maintainable analysis scripts (e.g., Python/MATLAB) and data pipelines for reproducible modeling, visualization, and reporting.
• Collaborate with metallurgists, process engineers, and operations team members to drive decisions, document results, and present recommendations to technical and business stakeholders.
• Opportunity to engage and lead efforts in new alloy, product, and process development at both the lab and production scale.

Typical responsibilities include developing physics-based and empirical models. Verify and validate them. Utilize modeling to drive manufacturing process improvements, impact product quality, lower manufacturing costs, and developing new products. Communicate results to management, colleagues, and customers in the form of written reports and oral presentations. Propose, defend, and execute project concepts for new products, cost savings, quality improvement, and process innovation. Collaborate with technology and research colleagues across ATI. Maintain industry expertise and current knowledge of developments in process modeling by experimentation, attending meetings and conferences conducted by trade associations, by reviewing trade literature, and by periodic visits to customer, supplier, and other ATI manufacturing locations.
