Research focus
JLK holds four clearances in this site's FDA records, all for software that triages radiology scans and sends a notification, the newest dated 24 March 2026. The company publishes its news on an outside blog and its careers page lists no jobs, so ask for United States customer references and for which MEDIHUB module each clearance actually covers before comparing it with an American stroke vendor.

JLK's own stock information page shows its shares as KOSDAQ 322510 under the name 제이엘케이. Checked on 2026-10-10, with no ownership change found.

A current price is not available in the automated United States market snapshot. Use the named exchange or the company investor-relations page for current trading data.

Careers and Qualifications

What to Know Before Applying

Work areas: The careers page sets out the company's hiring ideas rather than listing jobs, and points candidates to a hiring email address.

Qualification signal: This is a Korean company selling a regulated product into other countries, so regulatory submission work and overseas distribution experience count for more than model building alone.

Check current roles at JLK. A careers page is the source of record for openings. This profile does not claim a role is open unless the company lists it now.

Evidence and Regulation

FDA Clearances on Record

JLK appears on 4 cleared products in the federal 510(k) record, across 1 device type.

A clearance means the FDA agreed the product is close enough to something already on the market to be sold for that use. It is not a finding that the product helps patients, and it is not a ranking against anything else on this page. A company is linked to an FDA clearance only when the 510(k) applicant name on the government record is confirmed by hand to be that same company, including former corporate names. Name similarity alone is never enough, and rejected matches are listed below with the reason.
