Math Developer Jobs in Fullerton, CA (NOW HIRING)

About BEAM
Bridge to Enter Advanced Mathematics (BEAM) creates pathways for students from low-income, low-access backgrounds to become scientists, mathematicians, engineers, and computer scientists.
We provide BEAM students the same access to high-quality preparation in STEM as their more affluent peers, and we invest deeply in our students' success, with programming from middle school through college graduation focused on joyous, exciting, and rigorous mathematics, building vibrant communities, and supporting students in key life transitions such as college admissions and financial aid.
BEAM has grown from a small summer program serving 17 students in the summer of 2011 to a year-round, national program, serving 450+ students at six summer program sites and 600+ students in year-round programming in New York City and Los Angeles this school year. In addition, our BEAM National pilot program now reaches around 1000 elementary-aged students in seven different states, working to create a new nationwide pathway modeled on our local work. We've seen our students' successes first-hand, and it's backed by data: a quasi-experimental study found that students who attended our 7th grade summer program were 1.3X as likely to declare a STEM major as a matched comparison group.
