Technical Lead – Engineering at Tata Technologies

Job Description

Role Overview:

The SME Engineer Mixer – Urea Decomposition Reactor is a subject matter expert responsible for the design, calculation, product selection, performance evaluation, and release of the Urea Mixer within Exhaust Aftertreatment Systems (EATS). This role ensures the successful execution of EATS programs in alignment with TenPLUS phases of the product development cycle. The SME Engineer collaborates with Product Engineering (PE) teams, customers, and global technical experts to deliver efficient and high-performing solutions.

Key Responsibilities:

• Lead technical activities related to Urea Mixer development in EATS programs.
• Perform analytical calculations for product selection based on SOR (Statement of Requirements).
• Engage with global technical experts to explore solutions and present them to the PE team for customer discussions.
• Actively participate in Preliminary Design Reviews (PDR) and Product Final Release & Approval (PFR&A) meetings for assigned mixer projects.
• Ensure compliance with customer SOR requirements and maintain high-quality deliverables for prototypes and validation samples.
• Provide technical support to the PE team to meet project milestones and deliverables.
• Steer the execution of design validation and performance analysis for the Urea Mixer.

Interview Preparation Guide:

1. Understand the Fundamentals:

• Review EATS system architecture, particularly the role of the Urea Mixer in the SCR (Selective Catalytic Reduction) system.
• Study the principles of Urea Decomposition, mixing efficiency, and ammonia conversion.
• Understand the fluid dynamics and thermal management aspects of the Urea Mixer.

2. Master Technical Calculations & Product Selection:

• Refresh knowledge on analytical methods for mixer design and performance assessment.
• Be prepared to discuss computational fluid dynamics (CFD) and experimental validation techniques used in mixer design.
• Understand material selection criteria based on temperature, durability, and chemical resistance.

3. Gain Practical Industry Insights:

• Explore latest trends in aftertreatment technologies and emission regulations (BSVI, Euro VI, EPA standards).
• Review case studies or industry best practices in Urea Mixer design and performance optimization.
• Be ready to discuss failure modes and troubleshooting techniques in real-world applications.

4. Behavioral & Problem-Solving Questions:

• Expect questions on leadership, stakeholder management, and cross-functional collaboration.
• Prepare examples where you led technical projects, resolved design challenges, or optimized product performance.
• Demonstrate decision-making skills when evaluating design trade-offs.

5. Hands-on Tools & Software Knowledge:

• Familiarize yourself with CFD tools (ANSYS Fluent, Star-CCM+), CAD (CATIA, Creo), and simulation techniques used in mixer design.
• Review data analysis methods and tools like MATLAB, Python, or in-house calculation tools.
