At Classroom Mosaic, we're transforming instructional improvement by enabling K-12 leaders to capture, measure, and understand what happens in their classrooms. We're looking for a Full-Stack Software Engineer to help us build new features, scale our platform, and advance our mission of improving instruction in schools.

As a small development team, we are all generalists who tackle a wide array of new challenges. We need an experienced engineer who can pick up a project and drive it to completion—someone who thrives on ownership and autonomy. You’ll lead projects end-to-end, collaborate closely with product and client success teams, and help maintain a reliable, high-performance platform as we scale.

If you’re passionate about elegant design, exceptional user experience, and the power of technology to improve teaching, we’d love to hear from you.

• Build, launch, and improve user-facing features and core product experiences across frontend, backend, and mobile applications.
• Contribute to both new product development and improvements to existing products, focusing on user experience, architecture quality, and performance.
• Own projects end-to-end, from ideation through implementation and post‑launch iteration.
• Collaborate with our product, growth, and client success teams to translate real‑world workflows into intuitive, high‑impact features.
• Monitor and maintain the reliability of the platform, continuously optimizing performance, responsiveness, and scalability.
• Help document and evolve internal processes to promote best practices.
