Key Autism Services
Chelmsford, MA Full Time
POSTED ON 4/13/2026
AVAILABLE BEFORE 6/13/2026

Position Overview

We are seeking experienced Registered Behavior Technicians (RBTs) to join our team. In this role, you will implement behavior support plans and provide one-on-one ABA therapy to children with ASD, both in their homes and at our centers.

For RBTs providing in-home sessions you are never working in isolation — our model centers on consistent clinical support from your supervising BCBA and our broader clinical team. You will receive weekly supervision, along with regular connection and check-ins to ensure sessions are going well between supervision visits. This ongoing support helps RBTs feel supported while maintaining high-quality care in the home.
