Diffit

37d • Remote

About The Position

Diffit is the leading AI-powered instructional materials platform for educators, designed to help teachers do their best work more sustainably. We are earning real revenue, have achieved rare levels of traction with minimal funding, and are just getting started. Join a growing remote-first and mission-focused AI edtech company to help provide quality, safe and affordable instructional resources for teachers and students.
The Role
At Diffit, engineers work closely with Product and Design to build thoughtful, high-impact features for teachers. We’re a small, full-stack team, so you'll work across the stack (React on the frontend, Python/FastAPI on the backend + frontier LLMs from various providers) to ship end-to-end functionality (using AI agents to help, of course). Beyond feature work, you’ll help shape our architecture, improve internal tooling, and contribute to a platform that tens of thousands of teachers rely on every day. We move quickly, learn constantly, and stay focused on delivering real value to teachers.

Requirements

• 5+ years of engineering experience building and shipping web applications
• Proficiency with modern full-stack web development ideally using FastAPI, React, Postgres, or other similar technologies
• Strong communication skills including the ability to explain technical ideas clearly and collaborate cross-functionally
• Track record of ownership - you’ve taken responsibility for projects or major features and seen them through
• Bias toward action and pragmatic problem-solving - you know when to move fast, when to ask questions, and when to slow down
• Curiosity and a growth mindset - you actively seek feedback, enjoy learning, and care about improving your craft

Nice To Haves

• Startup experience preferred - we're a small team, and evidence that you thrive in similarly small, relatively unstructured, and highly dynamic environments is a big plus.

Responsibilities

• Drive Projects End-to-End
• Product-Oriented Thinking
• Communicate with Clarity and Candor
• Contribute to a Supportive Team
• Work Autonomously with Velocity
• Continuously Improve and Learn

Benefits

• The opportunity to work on a meaningful product that impacts the future of education.
