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.

AI/LLM Integration
- Integrate Large Language Models for content classification, skill assessment, learner feedback, and personalization
- Build information extraction systems to analyze learner responses
- Implement AI-powered features for conversation practice and multilingual support
Development Excellence
- Write clean, well-tested code — and apply the same rigor when reviewing AI-generated output
- Actively use and refine AI-assisted development workflows to improve your own productivity
- Collaborate with product managers, designers, and education specialists
- Contribute to A/B testing frameworks and learning experience optimization
Required Qualifications
- 5+ years of professional full-stack web development experience
- Strong proficiency in TypeScript, React, Python, and FastAPI
- Experience integrating with LLMs (OpenAI, Anthropic, or similar) for classification, extraction, or personalization
- Hands-on experience with AI-assisted development tools (Cursor, Claude Code, or similar) — and genuine comfort using them as part of your daily workflow
- Experience with PostgreSQL and API design
- Strong passion for EnGen's mission to help immigrants and refugees remove English as a barrier to career advancement
- Self-directed and able to work independently in a remote environment
Preferred Qualifications
- Experience building edtech or language learning platforms
- Knowledge of NLP and educational AI applications
- Familiarity with WCAG accessibility standards
- Experience with Railway, Cloudflare, or similar cloud infrastructure
- Multilingual capabilities, particularly Spanish
What We Offer
- Competitive salary and equity
