Enhance your clinical career with AB Spectrum, a team proudly named a Top Workplace by the St. Louis Post-Dispatch. We earned this recognition, which is based entirely on employee feedback, because we foster a culture where people feel valued, supported, and inspired to grow.
AB Spectrum provides specialized ReggioABA™ (Applied Behavior Analysis) therapy for young children (ages 1-6). Our foundation is ABA, an evidence-based therapy focused on developing communication, social, and adaptive living skills.
We’re seeking compassionate, reliable individuals to provide 1:1 Applied Behavior Analysis (ABA) therapy to children ages 1–6 with Autism Spectrum Disorder.
As a Registered Behavior Technician, you’ll work directly with children in a clinic-based setting, helping them build critical life skills through our unique, play-based ReggioABA™ approach. You’ll be supported by on-site Board Certified Behavior Analysts (BCBAs) and other team leaders every step of the way.
This is a physically and emotionally active role. You’ll spend much of your day on the floor with children, supporting them as they learn to communicate, potty train, and manage big emotions. At times, children may engage in behaviors such as screaming, biting, or hitting—you’ll be trained to respond calmly and professionally.
Reliability is key: families depend on consistent, committed staff to help their children grow. Attendance and punctuality are essential from your very first day of paid training through your work in the clinic.
