Senior Full-stack Engineer Full Description

About Diffit

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. Weâre 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, youâll 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.

Responsibilities

Drive Projects End-to-End
Engineers at Diffit own their work from kickoff through launch and beyond. That means designing, implementing, testing, and monitoring your features. It means being thoughtful about how your work fits into the bigger picture and leveraging agents effectively to ship quality code quickly.
Product-Oriented Thinking
We all care deeply about the teachers we serve. Engineers are expected to think critically about user needs, provide input on product decisions, and ensure our technical solutions actually solve real problems. Youâll collaborate closely with product, design, and customer success to stay grounded in what matters most.
Communicate with Clarity and Candor
Communication is a core part of engineering. Youâll explain tradeoffs, share progress, give and receive feedback, and collaborate across disciplines. We value clarity, curiosity, and a willingness to ask the hard questions early.
Contribute to a Supportive Team
We believe great teams are built on trust and shared responsibility. That means helping unblock others, pitching in when workloads are uneven, and treating teammates with respect and kindness.
Work Autonomously with Velocity
We move fast: not by cutting corners, but by staying focused. Engineers at Diffit are self-directed and tenacious. Tasks typically have a single owner, and itâs up to you to drive them forward with speed, pragmatism, and attention to quality.
Continuously Improve and Learn
We expect engineers to grow and to help others grow. That might mean learning a new tool, reflecting on a mistake, mentoring a teammate, or revising how we work together. Curiosity and humility go a long way.
Level Up The Team
Senior engineers are force multipliers. They own complex initiatives, provide technical direction and vision, and create leverage by proactively solving technical problems. Senior engineers raise the bar for the whole team.

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 - youâve 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
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.

What We Offer:

Competitive salary and benefits package.
Fully remote work environment with in-person offsites.
The opportunity to work on a meaningful product that impacts the future of education.
Collaborative and supportive team culture.

Salary:

$150,000-$250,000 per year plus stock options
