About Us:

Braintrust Tutors is a mission-driven organization committed to accelerating learning for the students who need it most. We partner with districts across the country to deliver high-impact, Science-of-Reading aligned literacy and math interventions that measurably change student trajectories. Our tutors are certified, trained educators who believe in the power of evidence-based instruction and personalized support. When you tutor with Braintrust Tutors, you join a community that values your expertise, equips you with turnkey technology, and surrounds you with coaching, collaboration, and a shared purpose: ensuring every child gets the chance to become a confident, successful learner. Educators choose Braintrust Tutors because their work here is felt immediately, supported consistently, and celebrated always.

About the Role:

We have opportunities in Reading and Math. You will be able to become an expert tutor in either or both. You choose!

As a Reading Tutor at Braintrust Tutors, you will work with elementary school students in a school setting to strengthen their reading comprehension, fluency, and critical thinking skills. Using our structured intervention programs and materials, you will deliver consistent, high-impact tutoring that meets each student where they are.

As a Math Tutor at Braintrust Tutors, you will work with students to strengthen their mathematical reasoning, number sense, and problem-solving strategies. You will provide engaging, consistent lessons using Braintrust Tutors' curriculum and materials, helping students build foundational math skills and confidence.

As an in-person tutor, our priority will be to match you with those engagements. However, you may be considered for additional online roles if you would like to complete your schedule with us.

Provide small-group or 1:1 reading/math tutoring to students developing literacy skills
Implement Braintrust Tutors' intervention programs as designed, using all materials with fidelity
Monitor student progress and adjust instruction accordingly
Maintain accurate records of student attendance and academic performance
Collaborate with the Braintrust Tutors Operations team and school staff to support student growth
Foster a supportive and engaging classroom environment that promotes focus and confidence
Follow school-site procedures and policies while maintaining a professional and dependable presence

Active/expired teaching license or at least 5 years of experience working with K-8 students in an educational environment
Knowledge of math instruction that builds number sense, procedural fluency, and problem-solving skills, with a scope and sequence ranging from counting to multi-digit arithmetic, including decimals and fractions. You also need expertise in foundational math operations, algebraic problem-solving and geometry
Strong classroom management and communication skills
Comfort collaborating with teachers and staff
Punctuality, professionalism, and reliability for all scheduled sessions
Reliable transportation and/or appropriate technology for instruction
A laptop with Windows or macOS that uses either Chrome/Edge Chrome 115+ (recommended), Firefox 115+ or Safari 16+. iPads are also acceptable with iOS 17 or greater with an external keyboard
Passion for literacy and closing opportunity gaps

Next Steps!

For in-person engagements, if you comply with our requirements, we will invite you to complete a one-way video interview via Spark Hire. After a successful review, you will be invited to join us for a live 30-minute interview with a recruiter before beginning your onboarding.

Braintrust Tutors has a multi-step onboarding process requiring approximately 4–5 hours to complete. You will create a Braintrust Learning Center account, complete self-paced policy and curriculum modules for your chosen subject areas (Math and/or Reading), set up your platform profile with required documents, submit to a background check and fingerprinting (if applicable to your assigned district), attend live Zoom curriculum practice sessions, submit teaching demonstration recordings, and apply to positions. Once matched, you will complete platform orientation and attend a Launch Call before beginning sessions. All resources are housed in the Braintrust Learning Center.
