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 are seeking resilient, high-energy individuals to deliver 1:1 Applied Behavior Analysis (ABA) therapy to children ages 1–6. This is a clinical, data-driven role focused on teaching fundamental life skills—not a traditional mentoring or talk-therapy position. Using our ReggioABA™ approach, you will transform play-based interactions into structured, scientific learning opportunities designed to help students reach critical developmental milestones.
In this role, you function as a clinical teacher, not just a caregiver. Working under the direct supervision of a BCBA, you will implement specific protocols to help children master everything from verbal communication to potty training. Because we focus on functional skill acquisition, your day will be physically active and highly structured, requiring constant engagement and precise data collection.
Success in this position requires a "professional-first" mindset. You will be the steady presence a child needs during challenging moments, which includes following a clinical plan to manage behaviors such as screaming, hitting, or biting. We are looking for candidates who value consistent, daily practice and are committed to meeting measurable goals through a scientific framework.
