Firstly, you will all need a visa to move to live in Spain.
Most people on this forum are moving here when they are retired with the Non-Lucrative Visa. I and several others have posted lots of details on this visa, which you could search for on this forum. The key requirements are that a). you can't work; b). you need to have approx. €27,000 for the first applicant and approx. €7,000 for each dependent - per year, for 5 years, as 'means of maintenance' (i.e. money to live off). c(. no criminal record; and d). pay for private healthcare for each applicant.
The other options are as follows:
1. Working visa - this needs to be applied for in conjunction with your employer - i.e. you can't just get a working visa and then move to Spain and try & get a job. This needs to be renewed every year and, for example, your employer may have to prove why they couldn't employ a native Spaniard instead of you. Note: Unemployment rates in Spain are high and the average salary in Spain is around 2/3rds of the average salary in the UK. You will also really need to be fluent or at least have good conversational Spanish, in addition to having the required qualifications, etc. to do the job.
2. Self-employed visa ('autonomo visa'). If you intend to be self-employed or start your own business, then you need this visa. You need a full business plan, evidence of contracts for work already in place; and sufficient 'means of maintenance' for you to live on if the business fails. Again, this needs to be renewed annually.
3. If you can satisfy any of the above for yourselves, your son may be eligible for a Student Visa, which has different requirements.
