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

• Deliver production software across our TypeScript/React frontend and Python/FastAPI backend — whether writing code directly or steering AI tools to generate it

• Build responsive web applications for diverse learners across desktop and mobile

• Design and implement scalable APIs to support our learning platform

• Develop real-time features for interactive lessons, conversation practice, and learner-coach communication

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
