Julia Hatfield didn’t always know she’d become an engineer designing custom implants that change lives. What she did know was that she loved problem-solving, math, and science—and that curiosity led her to a career in one of Indiana’s fastest-growing advanced industries.
In this conversation, Julia shares how she found her path, why Indiana is the ideal place to build a future, and offers advice for Gen Z students starting to think about their own careers.
Julia, take us back. How did your interest in life sciences and engineering begin?
In high school, I took an anatomy class and discovered how much I loved learning about the human body. At the same time, I already knew I enjoyed math and science, and I’ve always loved problem-solving. Putting all of that together, biomedical engineering felt like the right direction; it allowed me to innovate in ways that could truly help people.
What made you choose the University of Toledo for college?
Their bioengineering program required three co-ops. That was huge for me because it gave me the chance to get into the field, not just sit in a classroom. I wanted to see how engineering worked in real life, and those internships had a significant impact on my career.
How did you first connect with Zimmer Biomet?
I actually met them at a career fair in Toledo. I ended up doing two internships with them here in Indiana—one focused on shoulder implants, and the other on research using advanced microscopes to study how materials fail. Those experiences showed me how broad and exciting this work could be.
Tell us about your current role.
I’m a development engineer on the Patient-Matched Implants team at Zimmer Biomet. That means I design implants that are custom-made for individual patients, usually for shoulders. A patient undergoes a CT scan, and we turn it into a 3D model. Then, I design an implant that fits their exact needs. It’s highly specialized, and every case is unique.
Currently, I’m working on approximately 60 different cases simultaneously, making for a fast-paced environment. However, it’s incredible to know that something I design could alleviate someone’s pain and restore their mobility.
What excites you about your work?
For me, it’s seeing the direct impact on patients. I’ve been able to attend surgeries and watch implants I designed being used. It’s surreal. And it’s not just local — some of the implants I’ve worked on have gone to patients as far away as Japan. Knowing my work reaches people all over the world is really motivating.
Looking back, did you always know you’d be on this path?
Not at all. In high school, I didn’t have a detailed plan. I just followed my interests, took advantage of opportunities like internships, and let things fall into place. That’s something I’d want Gen Z students to know: you don’t have to have it all figured out. What matters is trying things, learning what excites you, and being open to change.
What advice would you give to students exploring Indiana’s advanced industries?
Surround yourself with goal-oriented people—they’ll motivate you. Don’t be afraid of mistakes. They’re inevitable, but they help you grow. Finally, get hands-on experience through internships, co-ops, or shadowing. Even if you don’t love it, you’ll learn what direction you do want to take.
Why Indiana? What keeps you here?
Indiana is the hub for advanced industries — especially life sciences. Warsaw is the orthopedic capital of the world. For someone like me who wants to innovate, collaborate with surgeons, and make a real impact, this is the place to be.
