Requirements

Bachelors degree in Mechanical Engineering or related field.
6+ years of experience performing CFD analysis using SIEMENS Simcenter STAR-CCM.
Strong fundamental understanding of fluid mechanics, thermodynamics, and heat transfer.
Exposure to thermal management of battery, motors, and power electronic components.
Exposure to numerical methods and engineering analysis.
Strong communication and presentation skills to share analysis results and drive discussions.

Nice To Haves

MS or PhD in Mechanical Engineering with emphasis in fluid dynamics and heat transfer, multiphase flows, IC engines and e-Machines.
Usage of High-Performance Computing (HPC) cluster with Linux OS and Slurm Scheduler.
Knowledge of test instrumentation (strain gauges, accelerometers, thermocouples, pressure transducers, flow meters, etc.).
Working knowledge of conventional internal combustion engines and marine propulsion systems.

Responsibilities

Conduct detailed/comprehensive simulations using Computational Fluid Dynamics (CFD) software Siemens Simcenter STAR-CCM+ to model fluid flow behavior and heat transfer mechanisms
Perform conjugate heat transfer (CHT) analysis of internal engines, marine drives, and transmission components to evaluate temperature distributions, cooling performance, and thermal risks.
Identify thermal drivers and provide clear, data‑driven design recommendations to improve durability, efficiency, cooling distribution, and component life.
Conduct multiphase hydrodynamic simulations for propellers, drives, and boat systems using multiphase CFD techniques (VOF, Eulerian‑Lagrangian) and moving/overset mesh to model gas–liquid–solid interactions.
Work closely with design and development engineers to help provide design input and perform trade-off studies that will improve the product. This includes evaluating different design options and assessing their impact on performance, weight, cost, and recommending the best solutions.
Work closely with test engineers to specify the necessary testing and instrumentation required to validate analysis results. This includes designing test plans, selecting appropriate sensors, and ensuring accurate data collection.
Document analysis findings and share the results with stakeholders, engineering partners, and leaders. This includes preparing detailed reports, presenting findings in meetings, and providing actionable recommendations based on analysis results.
Identify potential areas for new method development and work with experts to test and deploy. This involves staying up to date with the latest advancements in analysis techniques, conducting research to develop innovative methods, and implementing these methods in practical applications.
Continuously seek opportunities for improving analysis processes, tools, and methodologies. This includes participating in training sessions, attending industry conferences, and collaborating with peers to share knowledge and best practices. This also involves assessing software capabilities, identifying gaps, and recommending upgrades or new tools.
Coordinate work packages between onsite and offshore teams. This includes managing project timelines, ensuring clear communication between teams, and maintaining high standards of quality and consistency in deliverables.
