Naga Jishnu Vardhan J.

Experience

• Thesis Work Gränges Group AB · Contract Jan 2026 – Jul 2026 6 mos Finspång, Sweden • Investigated transverse surface cracking in 10-15 µm aluminium battery cathode foil using SEM/EDS, LOM, tensile testing, surface scans and image analysis in an industrial manufacturing environment.
  • Correlated defect geometry with cold-rolling parameters including pass reduction, roll roughness and lubrication, and documented findings to support production-quality and process-improvement discussions with Gränges engineers.
• Design Engineer E+mug Engineering Services · Full-time May 2022 – Jul 2024 2 yrs 2 mos Hyderabad, Telangana, India • Developed customer-specific mechanical components, assemblies, geo fixtures, grippers, special-purpose machinery (SPM), pass tables and assembly-line systems from concept through detailed design.
  • Created and updated parametric 3D CAD models in PTC Creo and Siemens NX, converting non-parametric skeleton models into robust parametric designs and producing manufacturing drawings, BOMs and technical documentation.
  • Managed product/design changes, drawing releases and mechanical interfaces while coordinating with simulation and multidisciplinary engineering teams to resolve fit, function and implementation issues.
  • Supported production-oriented development with focus on manufacturability, assembly, maintenance access, design reusability and practical improvements that reduced rework during implementation.
• GRADUATE ENGINEER TRAINEE KIA MOTORS · Full-time Jun 2021 – Apr 2022 10 mos Anantapur, Andhra Pradesh, India • Supported production-line quality verification for automotive interior trim and heat-insulation components, identifying deviations and coordinating technical follow-up with production and supplier-quality teams.
  • Performed structured root-cause analysis and process-improvement work using FMEA, Ishikawa, SPC, 7QC tools and Poka-Yoke to define and verify corrective actions.
  • Contributed to defect prevention and internal-scrap reduction through practical countermeasures, process-control improvements and close collaboration with manufacturing teams.
  • Participated in line audits, customer complaint investigations, supplier-quality coordination and structured countermeasure reporting, strengthening documentation, traceability and production communication.
