“Shaping the Future with Technology” – The Challenges of an Engineer Designing the Heart of Mass-Production Vehicles

Why did you choose ALTEN Japan?

I majored in material mechanics in the engineering department and built my career as a mechanical design engineer after graduation. As a new graduate, I joined a mechanical tool manufacturer, where I developed cutting tools like drills.

I joined ALTEN Japan through a career change, and this is my fifth year here. The trigger for this move was my decision to return to my hometown in Tochigi after getting married. My hometown hosts research facilities and racetracks for major automakers, and I had long admired automotive design.

During my job search, I prioritized two things: “working near my hometown” and “being involved in automotive development.” While I considered joining a manufacturer, my personality leans toward wanting to “experience a variety of challenges.” This led me to explore contract engineering roles.

Among multiple job offers, I ultimately chose ALTEN Japan. The decisive factors were the attractive working conditions and the significant autonomy offered by a growing company. Additionally, the stability of a large French parent company provided reassurance.

Before joining, I had concerns about job insecurity as a contractor, but those fears quickly dissipated once I experienced the stable work environment firsthand.

What Is Your Current Role?

I currently work at an automaker, designing chassis components for mass-production vehicles. My past projects include developing gasoline tanks and steering systems. My work isn’t limited to desk-based tasks—I also participate in real-world vehicle testing, contributing to “authentic manufacturing.”

Gasoline tanks must meet stringent safety regulations, such as collision resistance and leak prevention. Since these regulations vary by country and region, I frequently collaborate with overseas teams. English emails and meetings with colleagues in the U.S., Thailand, and China are part of my daily routine.

Design challenges often extend beyond theory—interference with adjacent components and manufacturing constraints require strong coordination across departments. I’ve learned that communication skills are just as critical as technical expertise.

What Does a Typical Workday Look Like?

While remote work is an option at my assignment, mechanical design often requires hands-on testing and physical inspections, so I usually work on-site.

Our flexible hours allow me to adjust my schedule as needed, whether leaving early for family emergencies or staying late for international meetings. As an early riser, I typically start work before 8 AM.

My daily routine begins with checking emails, followed by CAD modeling, meetings, and accompanying prototype tests. Before leaving, I organize tasks for the next day.

My mantra is: “Earn trust within 3–5 years.” As a contractor, I prioritize punctuality, thorough documentation, and keeping commitments. Ensuring development data is well-organized for successors is also key.

When do you feel a sense of achievement?

The most rewarding moment is seeing my name on a mass-production blueprint.

In vehicle development, prototype drawings can be revised endlessly, but mass-production blueprints remain permanent as long as the car is on the road. The first time I issued a blueprint with my name on it, I was overjoyed. Now, when I see cars I’ve designed on the street, I think, “That car has my blueprint in it!” and feel immense pride.

Full model changes take 4–5 years, making the sense of accomplishment at completion truly special.

I also receive frequent praise for my CAD skills—particularly for my speed and precision in shape modifications. Over time, I’ve developed an intuitive sense of “design balance,” which I consider one of my strengths.

What are your career aspirations?

I’m still deciding whether to specialize further in technical roles or transition into management. Currently, I lead a team of about 20 members, and while I’m interested in management, I also want more hands-on development experience.

ALTEN Japan is strong in IT, which has piqued my interest. I’m studying for the Fundamental Information Technology Engineer Examination and enjoy the process of learning new things, especially those moments when I open a textbook and think, “What is this?”

If I pursue management, I believe broader knowledge beyond mechanics will be essential, so I’m committed to continuous learning.

What kind of person thrives at ALTEN Japan?

ALTEN Japan is a growing company with greater autonomy than larger firms. It’s ideal for those who prefer diverse experiences over repetitive tasks and want to advance their careers dynamically.

The certification system is robust, making it particularly appealing for mid-career hires. The e-learning platform allows self-paced learning, which I find invaluable.

The variety of projects and skill levels available also suited me well. When I expressed interest in development, I was matched with my current assignment—exactly what I hoped for.

Another advantage of contract work is flexibility. I took parental leave as planned, and the ability to adjust staffing needs smoothly was a significant benefit. Witnessing my child’s growth during that time remains one of life’s greatest treasures.

What Are the Pillars That Support You?

I balance three pillars: family, work, and kendo.

At home, I reject traditional gender roles. I share household chores, often handling morning tasks to ease my partner’s burden.

I’ve practiced kendo since middle school and now teach at a local club. Preparing for my 4th-dan exam keeps me engaged. Kendo helps me clear my mind, relieve work stress, and even spark unexpected ideas—it’s indispensable to me.

While I strive to balance these three pillars, I sometimes lean too heavily toward work or kendo. In those moments, my wife and I communicate openly, supporting each other.
