Summary

My name is Ketav Majumdar and I am a recent graduate from the University of Southern California holding an MSc in Mechanical Engineering with a specialization in Advanced Manufacturing. My focus over the past 6 years has been in R&D, design, and manufacturing. My expertise lies within the manufacturing and processing of metals and alloys through machining, casting, sintering and extrusion. My proudest achievement till date is the development of a novel surface finishing process for titanium and Inconel aircraft engine components for Rolls-Royce, reducing process cycle time by 80% and generating annual cost savings of £1 million.Subsequently, I oversaw manufacturing, DFMA and operations support at 3Diligent increasing the organization’s global manufacturing presence in N. America, Europe, and Asia through the establishment of 30 production centers; exceeding expectations by 50%.

Experience

2019 Aug - 2020 Jan

Operations Intern

3Diligent / El Segundo

• Created and evaluated ~1k designs for clients in various industries to optimize assembly and production using DFM and GD&T and served as the only engineer to build and sustain client relationships, saving clients money while increasing revenue to $50k per week.

• Reduced material consumption and optimized additive manufacturing processes by repairing STL files, creating orientation and slicing simulations, and optimizing topology and generative lattice design, reducing production costs by 10-15%.

• Conducted root cause analyses on 2-3 customer complaints per month to investigate and resolve actions for AM challenges such as post processing, surface improvements, heat treatments, inserts/threads, and sectioning/welding, ensuring 100% customer satisfaction.

• Secured partnerships with 30 new manufacturing facilities in North America, Asia, and Europe, exceeding expectations by 50% through market research and competitor analysis.

• Researched materials and processes to establish a material selection database for company-wide transfer to a new software platform, increasing website traffic by 25%.

2017 Oct - 2018 Jul

Project Engineer / Project Officer

Rolls-Royce Corporate Lab / Singapore

• Supervised 20 suppliers, engineers, and toolmakers in purchase and development of >£100k in parts, fixtures, jigs, and components per month, maintaining customer satisfaction score of 95% by achieving on-time milestones.

• Constructed numerical methods and DEM software to build and conduct product simulations, attaining 97% accuracy and exceeding stakeholder accuracy requirement by 2%.

• Built an exclusive fixture design by integrating force, pressure, torque sensors and high-speed cameras, increasing productivity by 45%.

• Authored and released quarterly technical reports to 9 stakeholders in Germany, the UK, and Singapore, collaborating closely with stakeholders and 2 subject-matter experts to exceed annual KPIs by 30%

• Applied improvement and lean manufacturing principles to implement new and refined manufacturing processes, resulting in a projected annual cost savings of £1M.

• Collaborated with design team in Germany to create a new machine that reduced the duration of surface-finishing process for titanium aircraft components by 80%.

• Upheld quality control standards as per ISO 90001 and deployed Total Quality Control, Lean Six Sigma, and Lean Manufacturing to promote and sustain productivity and positive company culture.

• Authored 3 scientific papers accessed and cited by 108 people, 1 published in the Journal Manufacturing Technology Management and 1 won Best Paper Award at CIRP conference.
