The posting

Originally founded in 1991 as Harlem RBI, DREAM has grown to annually serve more than 2,500 youth across East Harlem and the South Bronx through a network of seven PreK-12, extended-day, extended-year DREAM Charter Schools and community sports-based youth development programs. Through our commitment to rigorous academics, social-emotional learning, deep family and community engagement, and health and wellness, we create lifelong learners who are equipped to fulfill their vision of success in and out of the classroom. We dream big, as well, with an aggressive five-year plan to expand to serve 3,500 students across seven schools—growing our organization’s impact and leveling the playing field for all children.

Reporting to the Infrastructure Manager, the Senior Systems Administrator ensures that DREAM’s technology infrastructure is secure, reliable, and ready to scale across four campuses of a K-12 charter school network.

The ideal candidate is a mission-driven professional who believes students of all backgrounds can achieve at high levels.

  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
