Full-Stack Software Engineer

About the Organization   EnGen offers an at-scale, AI-powered approach to English instruction, designed to solve a systemic access issue: Adult English learners now represent 1 in 10 working-age adults in the U.S., yet the workforce system serves the needs of just 4% of these workers.   A Certified B Corporation, EnGen is filling the gap by partnering with employers, adult educators, workforce development organizations, and state governments to connect job seekers and incumbent workers with English skills, career pathways, and employment in high-demand industries. EnGen's workforce-aligned approach addresses employers' recruitment and retention challenges and advances learners' economic mobility.   Position Overview   We're looking for a Full-Stack Software Engineer to help build the technology that empowers adult English learners to achieve their career goals. You'll develop and enhance our AI-powered learning platform using TypeScript/React on the frontend and Python/FastAPI on the backend.   We expect our engineers to be fluent in AI-assisted development — using tools like Cursor and Claude Code to write, review, and ship code faster and at higher quality. You should be comfortable directing AI to generate code, critically evaluating what it produces, and knowing when to write it yourself. Full-Stack Development
