Introduction
Hello, I’m Suhin Kim, a Mechanical Engineering Fellow and co-founder of Upgrade Manufacturing, Inc. I’m originally from South Korea, with a background in mechanical design algorithms and vehicle system development. I enjoy understanding the physical world problems and industrial challenges through mathematical modeling, which eventually led me to pursue a role in the startup company. It’s been a long and unique journey.
I earned my B.S. and Ph.D. in Mechanical Engineering from Seoul National University and joined Hyundai Motor Company as a research engineer. In graduate school and at Hyundai, I focused on simulation-based design techniques like topology optimization, mainly for conceptual vehicle system design. However, my research was distant from real-world manufacturing, so I felt I was in the gray area between academia and industry. In particular, I had many difficulties due to a lack of knowledge of manufacturing processes, so I decided to start postdoctoral research to shift my research focus. I left the company and joined MIT to focus on 3D printing and digital manufacturing. It deepened my understanding of the entire engineering process, from conceptual product design to production planning. Also, based on it, I found a way to harness all my skills in product design and mechanical simulations for real-world manufacturing.
During my time at MIT, I was also fortunate to connect with an incredible team. Together, we founded Upgrade Manufacturing, Inc., a company focusing on helping small- and medium-sized manufacturers adopt advanced AI and digital manufacturing technologies. As a co-founder, I now work on designing business models and product concepts, seeing my career paths converge in a new chapter with this startup.

career options
Mechanical engineering encompasses a broad range of areas across multiple industries. Regardless of the sector, mechanical engineering roles can generally be categorized as follows:
Design engineers work from conceptual design to detailed design, applying fundamental physics principles to set design objectives and determine key parameters that optimize performance while satisfying constraints. The scope of mechanical design is broad, covering not only structural design but also fluid mechanics devices, robot mechanisms, and control systems.
In product development, the cycle of design, manufacturing, and testing is essential. Testing engineers design experiments, measure performance, and provide feedback to designers for improvement. They should be knowledgeable about various types of sensors and measurement devices to effectively design testing methods and equipment.
Combining simulation with physical testing can significantly reduce development efforts and minimize trial and error. Simulations can also replace large-scale or hazardous physical tests by replicating physical behaviors virtually. Simulation engineers develop models and set simulation conditions, relying on fundamental knowledge of mechanics and physics.
Manufacturing engineers design and optimize production processes to balance cost, productivity, and quality. They understand the advantages and limitations of various manufacturing processes and provide feedback to improve design for manufacturability.
Project managers with a background in mechanical engineering oversee the entire process, from concept development to quality management. They schedule timelines and allocate resources to ensure each stage of product development meets its goals.
With the rise of ML and AI, mechanical engineering increasingly incorporates these tools. Traditionally, engineers used optimization approaches to improve product performance, system reliability, and control automation, often reducing experimental requirements through DoE (Design of Experiments). Today, ML/AI researchers with domain knowledge in mechanical engineering are dedicated to applying advanced machine learning and AI techniques, making this a distinct and growing field within mechanical engineering.

skills
What are the main hard skills you use on a daily basis in your current job?
Input-output relationships in a physical system can be represented through mathematical models, such as deformations under external loads and boundary conditions in structural mechanics. Based on my background in mechanics and physics, I build these models for simulations and predict outputs accordingly.
Sometimes, building fully analytical or numerical models is challenging due to limited system information or the complexity of coupled physical processes. In such cases, I analyze experimental datasets directly to create models, select subsequent testing points, and optimize parameters.
I apply appropriate optimization algorithms to each problem, based on my experience. Since no single algorithm fits all engineering problems, selecting the best one for each problem is essential. For example, I use gradient-based topology optimization algorithms for structural conceptual design, bio-inspired approaches for designing tool paths in metal 3D printing, and machine learning techniques for production planning.
What are the main soft skills you use on a daily basis in your current job?
I often need to communicate with audiences who lack a background in mechanical engineering, while sometimes also covering detailed information for in-depth discussions. Before preparing a presentation, I consider who my audience is and try to see things from their perspective. My extensive presentation experience in academia and industry taught me how to design materials/pitches based on the audience's interests.
I believe engineering should always address real, practical problems and resolve industry pain points. However, maintaining this broader perspective can be difficult when tackling small yet complex scientific challenges. I’ve learned that the best way to avoid losing sight of this is to consistently listen to the real concerns of various field experts. I continue to hone my interview skills through customer interviews and meet many stakeholders in the manufacturing industry to collect information.
After presenting my ideas effectively and listening to customers' needs, I look for opportunities that align mutual interests. This approach can lead to win-win partnerships, and I often invite others to create a better partnership structure. My experience in startup business design enables me to practice the required skill for partnership development every day.

:
My first career experience was somewhat like pitching a tech concept to a company. After spending 1-2 years on my initial graduate school research, I reached out to various teams at the R&D center of Hyundai Motor Company to present my research concept and gather feedback on its potential industrial applications. Although it was a challenging and sometimes frustrating process, after 4-5 rounds of discussions over six months, I finally found a team that aligned with my work. The team lead supported my Ph.D. research for four years, and I decided to apply for the company after graduation. Throughout those six months of iterations to find the right collaborative team, I focused on learning and adapting based on the feedback from each meeting.
The process of finding a postdoctoral research position was also challenging. I had no prior experience working internationally, so I tried everything I could to get more chances. I remember reading postdoc job postings to identify recurring keywords, which helped me understand the current trends in the U.S. academic field. Since I was based in Korea and lacked an international network, this approach was invaluable for figuring out the interests of research group leaders. Additionally, I studied materials from government institutions that outlined future research fund keywords or directions. To strengthen my preparations, I also sought feedback from former colleagues and friends who had successfully secured research positions in the U.S. After six months of persistent effort, I finally received an opportunity to join a research group at MIT.
Starting a company with my colleagues was also a lengthy process that included designing the business model and securing investment. However, my previous job-search experiences made me more resilient, even during times of uncertainty about the future.
What would you tell your younger you regarding building your current career?
Waiting for the next step is always difficult. Sometimes, it takes more than a year. I still go through similar processes every day, but now I understand that these things take time. If I could give advice to my younger self, I would say: think big and focus on what you can do now to prepare for the future. By doing so, you'll be ready to seize important opportunities when they come.
