Finding jobs for coders are a bit more difficult (in comparison to signature bounties that happen here) since majority of coders/programmers use other websites (more exposure and easier to find a job).

1. You can open your own thread in "Services" section and wait for clients to hire you.
2. You can use the following websites (I'm not vouching for any of these, since I never tried using their platforms):
    a. XBTFreelancer
    b. cryptogrind
    c. Coinality
