About the Job:

STEM Middle School/High School Teacher (On-Site Classroom Instructor with Virtual Support)

Location: On-site | Pinnacle Charter Schools – Casa Grande Campus, Casa Grande, Arizona


This is not a remote role.

About Us:

Pinnacle Charter Schools, operated by MGRM Pinnacle, is a Cognia-accredited network of alternative, for-profit charter schools serving students across Arizona. Established in 1995, we offer a flexible, year-round model of instruction that blends online learning with in-person support at our school sites. Our mission is to serve students who need a second chance—or a different approach—to succeed.

Our student population includes those who are behind in credits, face life challenges, or haven’t thrived in traditional school systems. At Pinnacle, we prioritize flexibility, individualized learning, and meaningful relationships over conventional structures—offering a supportive environment where students (and teachers) can grow.

The Opportunity:

We’re seeking a compassionate and adaptable STEM Middle School/High School Teacher (On-Site Classroom Instructor) to join our team at our Casa Grande campus. In this role, your primary focus will be working directly with students attending our physical school site. You’ll provide 1-on-1 tutoring, foster classroom engagement, and ensure students are on pace to complete—and pass—their courses.

In addition to classroom responsibilities, you’ll also play a role in outreach efforts that help boost enrollment and strengthen community connections. Finally, while your main focus is site-based students, you will also support a small group of online learners, applying the same instructional and mentoring skills in a virtual setting.

This position is ideal for educators who thrive in small-group or individualized settings, believe in second chances, and want to make a real impact on at-risk youth in a flexible, non-traditional learning environment.

What You’ll Do:

• Provide daily on-site 1-on-1 tutoring to support student learning and academic growth.
• Manage a classroom environment that is safe, engaging, and conducive to learning.
• Motivate students to stay on pace with their courses and ensure academic progress toward graduation.
• Track student performance and intervene when students are falling behind academically or behaviorally.
• Support classroom culture through active monitoring, mentorship, and relationship building.
• Contribute to outreach initiatives designed to increase enrollment and strengthen community awareness.
• Maintain accurate records of attendance, interventions, and student outcomes.
• Support a small roster of online students, providing instruction, progress monitoring, and feedback.
• Communicate regularly with students and families to encourage engagement and accountability.
• Participate in professional development and staff meetings at the district office.
• Perform other duties as assigned to support the mission of the school.

What You Bring:

• Bachelor’s degree in education or a related field (Master’s preferred but not required).
• Arizona Teaching Certificate OR at least 25 credit hours in your subject area.
• Classroom teaching experience, preferably with at-risk, alternative, or non-traditional student populations.
• Strong classroom management skills with the ability to balance structure and empathy.
• Proficiency in Microsoft Office, Google Suite, and learning management systems.
• Excellent verbal, written, and digital communication skills.
• Strong organization, time management, and self-direction.
• A mission-driven mindset, with empathy for students facing personal or academic challenges.

Why Join Us:

• Directly impact the success of students who need support, structure, and encouragement.
• Work in a stable, year-round teaching position with steady income.
• Be part of a collaborative and mission-driven team of educators.
• Enjoy the variety of supporting both in-person and virtual learners.
• Participate in meaningful outreach efforts that grow our community and student body.
