Quick answer: In Michigan, the big Korean names are Hyundai’s engineering arm near Ann Arbor and LG Energy Solution’s new Lansing battery plant. Ohio has the Ultium Cells (GM and LG) and L-H Battery (Honda and LG) plants, and Indiana has the StarPlus Energy battery venture in Kokomo and SK hynix’s new chip packaging plant in West Lafayette. Several battery lines have shifted toward energy storage, so check each site’s latest status before you apply.
Korean employers in the Midwest are not just one big battery plant. There are R and D offices in the Detroit suburbs, battery plants across three states, and a chip packaging fab rising near Purdue. Here is who is hiring, what they hire for, and how to read the news before you apply.
Key takeaways
- Korean companies in Michigan split into two worlds: engineering offices near Detroit and battery plants across the state.
- Ohio and Indiana are battery country, with several joint ventures now under new ownership.
- Energy storage, not EVs, is driving much of the 2026 hiring.
- The name on your offer letter may be a joint venture, not “LG” or “Samsung.”
- Read the last six months of news on any site before you interview there.
Two job markets in one region
Detroit is still the center of American auto engineering, so Korean automakers and suppliers keep design and technical teams close to their U.S. customers. Korean battery makers, meanwhile, built plants near automaker partners like GM, Honda, and Stellantis.
That gives the region two very different job markets. Engineering offices hire for vehicle testing, software, electrical design, and account management. Plants hire for production, maintenance, quality, and EHS, often in big waves during a launch. Knowing which one you fit makes your search much faster.
Korean companies in Michigan
Hyundai America Technical Center (HATCI) is Hyundai Motor Group’s North American design, technology, and engineering division, headquartered in Superior Township near Ann Arbor. In August 2026 it leased an additional office of about 45,000 square feet in Ann Arbor, according to CoStar.
LG Energy Solution Lansing was originally planned as GM and LG’s third Ultium Cells plant. GM sold its stake to LGES, and the plant started production in August 2026, as GM Authority reported.
Engineering-focused employers here tend to want engineers with automotive experience, people who understand OEM programs, and sometimes Korean speakers who can coordinate with HQ engineering teams.
The Midwest trade-off is real, and it’s mostly about lifestyle. The hesitation I hear most about plants in Michigan, Ohio and Indiana isn’t the job. It’s the location: small towns, thin infrastructure, few Korean restaurants, not much to do after work, and winters that are genuinely cold.
The people who settle in well usually made the math work. Rent is much lower than on the coasts, and they negotiated a higher base before they moved. With more money left over each month, a quiet town gets a lot easier to live with.
If you’re weighing a Midwest offer, compare what’s left after rent, not just the salary number, and visit the town once before you sign.
Korean companies in Ohio
Ohio’s Korean employers are mostly battery makers, and 2026 brought both cuts and comebacks.
- Ultium Cells (GM and LGES), Warren: production stopped in January 2026 after weak EV demand, and about 1,300 workers were laid off. The plant restarted in August 2026 with roughly 1,400 people, InsideEVs reported.
- L-H Battery Company (Honda and LGES), Jeffersonville: began mass production of energy storage cells on July 1, 2026, with more than 1,000 associates and a target of about 2,200, according to the builder’s announcement.

Korean companies in Indiana
- StarPlus Energy (Stellantis and Samsung SDI), Kokomo: in February 2026, electrive reported that Stellantis was exploring an exit from the venture. Confirm the ownership and product plan before you apply.
- SK hynix, West Lafayette: broke ground on August 27, 2026, on a more than $4 billion advanced packaging plant for AI memory in Purdue Research Park, with about 1,000 jobs expected once production begins, per Purdue.
SK hynix is the one to watch if you have semiconductor, cleanroom, or packaging experience. Construction-phase hiring usually starts with engineers and facilities staff, and technician hiring tends to build closer to production.
| Company | Location | Status |
|---|---|---|
| Hyundai America Technical Center | Superior Township and Ann Arbor, MI | Added Ann Arbor office, Aug 2026 |
| LG Energy Solution | Lansing, MI | Started production Aug 2026 |
| Ultium Cells | Warren, OH | Restarted Aug 2026 |
| L-H Battery | Jeffersonville, OH | Mass production since July 2026 |
| StarPlus Energy | Kokomo, IN | Ownership under review |
| SK hynix | West Lafayette, IN | Under construction |
How to stand out when you apply
A few habits will put you ahead of most applicants.
- Find the real legal employer. Ultium Cells, L-H Battery, and StarPlus Energy are joint ventures with their own HR teams and careers pages.
- Check what the plant makes now. Several sites planned for EV cells now build energy storage cells. Mentioning that shift in an interview shows you did your homework.
- Ask about stability. After the 2026 layoffs, it is fair to ask how the team handled the slowdown and what the hiring plan looks like.
- Lean on transferable skills. Auto plant, chemical, food, and pharma experience all translate well to battery quality and safety roles.
- Expect Korean colleagues. Many sites have Korean engineers on assignment during ramp-up. The Korean work culture guide explains what that looks like day to day.

Roles these employers hire most often
- Engineering offices: vehicle test and validation, electrical and software engineers, program managers, OEM account managers.
- Battery plants: production associates, maintenance and PLC technicians, process and quality engineers, EHS specialists.
- Business support: HR, finance, procurement, IT, and logistics.
- Bridge roles: coordinators and interpreters who connect U.S. teams with Korean engineers and HQ.
Korean language skills help most in bridge and coordinator roles. For engineering and plant jobs, your technical experience usually matters more.
FAQ
Are Midwest battery plants still hiring after the EV slowdown?
Yes, but hiring has shifted. Some EV lines cut staff in 2026, while energy storage production ramped up in places like Jeffersonville. Check each plant’s careers page for current openings.
Do I need to speak Korean?
For most roles, no. English is the working language for local teams. Korean is a plus for coordinator, interpreter, and HQ-facing roles, and the posting usually says so.
When will SK hynix in Indiana start hiring?
Engineering and facilities roles typically come first, with larger technician hiring closer to production. Watch SK hynix’s official job board and Purdue’s announcements.
