What the rules say about code 8139
Appendix Skilled Occupations lists this code in Table 6, and the gov.uk eligible occupations table labels it “Ineligible”.
Table 6 lists the occupations that cannot be sponsored on the Skilled Worker, Global Business Mobility or Scale-up routes. The rules give three reasons and do not say which applies to each code: the job does not meet the required skill level, it has to be sponsored on a different route, or people subject to immigration control cannot apply for it.
No salary, however high, makes a Table 6 job eligible, and a sponsor cannot choose a different code to get round it (SW 6.2, below).

- Manufacturer (metal goods mfr)
- Saw doctor

Who chooses the occupation code
The employer does, not you and not GoRizzume. The sponsor picks the code when it assigns the Certificate of Sponsorship, and Appendix Skilled Worker (SW 6.2) lets the Home Office refuse the application if it has reasonable grounds to believe a less appropriate code was chosen because the right one is not eligible, has a higher going rate, or is not on the Immigration Salary List. The duties decide the code, not the job title.
So treat this page as the rules for code 8139, not a verdict on any particular offer. Ask the employer which code they will use, then check that code. If you are unsure, the CASCOT coding tool suggests codes for a job title, and gov.uk says to make sure the description matches what you will actually do.

Find an employer that can sponsor
Only an employer on the Home Office register of licensed sponsors can sponsor a Skilled Worker visa, and a licence means they can sponsor eligible roles, not that every job comes with sponsorship.

Who decides which occupation code goes on a Certificate of Sponsorship?
The employer. The sponsor chooses the code when it assigns the certificate, and the Home Office can refuse the application if it has reason to think a less appropriate code was chosen to get round the eligibility or salary rules. A job title alone does not decide the code: the duties do. Ask the employer which code the offer will use.
