About Primer
Primer is a growing network of K–8 schools restoring the timeless foundations of American education. Inspired by the original teaching primers that shaped a nation of readers, thinkers, and builders, our schools begin with what has always worked, and build for what lies ahead. Close-knit learning environments. Skilled educators. A culture that takes kids seriously as learners and leaders.
Primers shaped the first 200 years of American children. Primer will ready them for the next.
The software we build powers our Microschools end-to-end. From day one it helps teachers source real estate, recruit students, and provide an (actually) personalized education to every student. It offers rich insights to parents, enables virtual teachers to deliver exceptional experiences, and runs our back-office operations stack. We have a huge surface area to cover and a lot of hard work in front of us.
We’re building a small team of exceptional, hands‑on engineers to play a critical role in building Primer.
Role overview
We are seeking a talented Full Stack Engineer to join our team. In this role, you will be responsible for helping redesign the school experience around modern technology. You will build features that teachers, students, and families will rely on every day, while solving real‑world problems in education.
This role is based in San Francisco and is in office 5x per week.
What you’ll do

• Tech stack: Work with TypeScript, NodeJS, GraphQL, Prisma, Postgres, NextJS, React, and Relay.
• Collaborative environment: You’ll work daily with team members from engineering, product, design, and our academic program.
• Ownership & growth: Take full ownership of projects and expand your skills. You’ll have the opportunity to lead initiatives that shape the entire product, with room to learn and grow along the way.
• Engineering culture: Play a key role in setting the foundation for our engineering culture as we grow the team.
• Build quality product: We set a high bar for quality, so expect to work hard to deliver excellence.

What we’re looking for

• Passion for education: You have an unbridled passion for fixing the US education system. This work is incredibly hard. But if we succeed, it will be the most fulfilling work of our lives. On the days and weeks that it feels like we’re chewing glass, there are only two things that will get you through: a deep passion for fixing this problem, and looking around and seeing a team that shares that passion. We can guarantee the latter, but only you can guarantee the former.
• Thrives in the unknown: The unknowns of the early‑stage fuel you. You love rolling up your sleeves and figuring out what needs to happen.
• Engineering fundamentals: You have a strong grasp of engineering fundamentals and know how to apply them in real‑world situations.
• Pride in craftsmanship: You take immense pride in your craft. Watching a session replay of a user having a bad experience with product you built makes you sick. Every detail matters.
• Building from zero: You have experience and love owning a feature or product from idea to live in production with active users.

Competitive salary plus equity
Benefits: Generous health, dental, vision, and retirement benefits included.
Primer is a mission‑first company. We believe our mission is the highest‑leverage way we can create positive change. In service of that, we keep work centered on mission execution and avoid social or political activism at work that’s unrelated to the mission. If that energizes you, we’d love to see you apply.
