I'm not an attorney, but I understand that you need to find an employer willing to sponsor a H1-B visa for you, which will allow you to work legally in the US. You must also meet the requirements for an H1-B visa sponsorship. You can find information about this visa in the USCIS.gov website, and under https://www.uscis.gov/eir/visa-guide/h-1b-specialty-occupation/understanding-h-1B-requirements.
There are dedicated websites where you can find companies hiring foreign individuals, and also agencies. You may want to research, but be careful with any visa fraud. Also, big tech companies are more willing to sponsor visas for qualified workers. You can find available positions by checking their specific company website, and at LinkedIn. I do not recall any website/company at the moment, but I will follow up with you, if I find any website or company to recommend.
Hope this help a bit.
