At Castrol, success knows no bounds. We offer a fast-paced learning environment where you can develop your career in specialized functions.  Castrol India has a proud legacy of championing top talent both locally and globally.

We are currently looking for an Expert Technologist – Modelling and Simulation for India based at Patalganga with details mentioned below.

What you will do...

TheEngineer – Thermal Management providesdeep technical expertisefor Castrol insystem-level thermal modelling and simulation, with a primary focus on electrified powertrain, battery, motor, and fluid-based thermal systems.  The roletranslates advanced physical modelling intoactionable guidance for research prioritisation, formulation strategy and partner-led innovation programmes.

The role operates at the intersectionof simulation, fluids, materials and system design – influencing bothinternal R&D direction andexternal collaborations with key customers to build new business opportunities for Castrol.

Key accountabilities include:

System-level thermal modelling and simulation

• Develop and apply1D and system-level thermal models integratingfluid design with components such as pipework, pumps, heat exchangers, batteries, motors, and electronics to evaluate whole-system performance rather than isolated components.
• Quantify and compare cooling architectures (e.g. indirect vs direct / immersive cooling) across multiple applications, includingbatteries, motors, and data-centre-relevant systemsfor automotive and non-automotive areas.
• Use modelling outputs toguide engineering trade-offs and decision-making, not just reporting results.

Thermal management of electrified systems

• Lead modelling activity forbattery thermal management, including optimisation of flow channels, heat transfer paths and fluid distribution at cell, moldule and pack level.

• Supportelectric motor and power electronics cooling challenges, evaluating novel fluids, architectures and heat rejection strategies.
• Contribute to projects coveringultra-fast charging, electrification, and hydrogen-adjacent thermal challenges.

Simulation-led research prioritisation

• Use simulation to assess the“size of the prize” for different formulation or fluid technologies.

• Provide quantitative insight on howfluid properties translate to system-level benefit, informing which R&D routes should be prioritised.
• Reduce reliance on costly or slow experimental iteration byfront-loading decisions with modelling insight.

Programme and partner engagement

• Act as asubject-matter expert on externally funded and partner-led projects.
• Engage with multiple internal teams (e.g. EV Fluids, formulation scientists, hardware engineers) to ensure modelling outputs are usable, relevant, and timely.
• Provideexpert input to reviews, capability discussions, and technology strategy forums.

Technical stewardship and capability development

• Shape and evolve thermal and system-level modelling capability within Advanced Fluids Research.
• Mentor and technically guide colleagues on modelling approaches, assumptions, limitations, and interpretation.
• Maintain awareness ofstate-of-the-art approaches in thermal management, simulation, and electrified systems.

What you will bring...

• Degree in mechanical, aeronautical or automotive engineering.
• Minimum of15years’ experience in industry using STARCCM+ CFD modelling software.
• Strong background influid mechanics with experience in electronics modelling and/or automotive CAE applied to real systems.
• Strong expertise inmultiphase modelling, especially 1D and 3D CFD of HVAC systems.
• Desirable experience using Siemens AMESim.
• Proficiency in CAD, preferably Siemens NX.
• Desirable expertise in battery modelling.
• Ability to interface with High Performance Computing (HPC) resources, basic knowledge of Linux scripting.
• The skill to create tools and methodologies to reduce complexity without sacrificing quality.
• Ability to translate complex modelling outputs into clear engineering and strategic recommendations.
• Clear and effective communicator with excellent written and spoken English.  You will engage both technical and non‑technical audiences globally at various organisational levels, bringing gravitas and credibly to influence and support change.
• Strong problem‑solving, analytical and conceptual design skills.
• Delivery‑focused with excellent planning, organisational and execution capability; able to autonomously navigate complex and ambiguous technical challenges at pace.
