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. 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. 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. You’ll 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. You’ll 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 it’s 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 - 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 - 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.

Our Team Dandelion Health was founded in 2020 by experts in health tech, hospital systems, academia, and clinical AI. We are building the world’s largest AI training and clinical development platform. Today, we pride ourselves on our ability to make data access as easy as possible for AI developers, pharma, and medical devices, while raising the bar for patient safety and data quality. Tomorrow, we will be the place where any healthcare organization can go to build a responsible clinical AI product. Our culture is all about learning from data and improving, so we can help our clients improve health through AI. Meet the rest of our team here. Our Data We partner with health systems to safely and ethically make their de-identified patient data available to AI developers. Currently, the data is acquired from Sharp HealthCare, Sanford Health, and Texas Health Resources – with two additional U.S. health systems joining soon. We have clinical data dating back to July 1, 2016. This data represents over 10 million patients and includes but is not limited to: - Structured data (e.g., 100% of the EMR, including some claims) - Unstructured text (e.g., clinical notes, radiology reports) - Images (e.g., DICOM, pathology) - Video - Waveforms - Continuous streaming monitoring data Your Role Dandelion treats patient privacy as a top priority, and our privacy preserving processes need to be best in class. These processes involve redacting or masking protected health information (PHI) e.g., patient names or event dates. As an engineer focusing on privacy and de-identification, you will: - Partner with our Director of Privacy and Clinical Informaticists to define de-identification rules at a granular level (e.g., column in an EMR table, metadata field in an image or waveform). - Create software that performs these de-identification rules at high scale (we de-identify billions of rows of data and millions of images each month). - Generate and execute quality assurance plans to validate our de-identification processes. - Run de-identification pipelines in health system cloud environments, and optimize these pipelines to minimize error rates, improve processing efficiency, and reduce manual effort and cost. Required technical skills - 2+ years of development experience in Python or an equivalent language in a professional setting, across the full software development lifecycle (design, implementation, testing, deployment, maintenance); - Familiarity with one or more command languages (e.g. Bash) and SQL. Required non-technical skills - Demonstrated ability to design and improve workflows, including associated operating procedures and quality assurance; - Strong analytical decision-making and organizational skills; - Perseverance and practical problem solving; - Humility and strong team collaboration; - Enthusiasm about protecting patients’ personal data. Preferred skills - Proficiency with data structures such as Pandas DataFrames; - Previous software deployment in a cloud computing environment (e.g., AWS, Azure); - Familiarity with virtualization and containerization (e.g., Docker, VMware); - Prior experience working with healthcare data; - Experience interacting with non-technical stakeholders to deploy software solutions. Team Benefits - Remote work and flexible hours. Availability needed for meetings, which we try to keep to a healthy minimum - Complete wellness benefits including healthcare, dental, vision, PTO, sick days and more. Ask for details - Professional development days to build your skills - Collegial work environment - Academic bent towards inquiry and problem solving but start-up speed and flexibility - Great balance of focus time to work on projects but easy to access team members to discuss issues and work collaboratively - Dandelion is a mission-driven company that is focused on improving patient care
