RSJ was formed in 2007 as a member of the
NPSL. In 2013, the NPSL crafted an award in memory of Alexander Arellano. Alex, the middle son of Real San Jose owner Nick Arellano, died in 2012 at the age of 25. The award goes to the NPSL's top coach of the year. Since Real San Jose moved to the UPSL the award is now given to the "Best RSJ Teammate" of the year. After ten years of competing in the NPSL, the club made the switch to the
UPSL in 2017. In 2020, RSJ moved to the National Soccer League. In 2024 RSJ once again showed leadership in the soccer community and founded the NPSL's Regional Division. In 2025 RSJ returned to the NPSL Tier 1. ==Year-by-year==
