Full Stack Engineer

• Modern UI Development & Architecture

Build and maintain modular, reusable components using React, React Native, TypeScript, and Tailwind CSS.

• Responsive & Mobile-Optimized Design

Create fluid, device-agnostic experiences that perform across desktop, tablet, and mobile.

• Design Implementation

Translate high-fidelity designs into production-ready code. Contribute to and uphold shared component libraries and design systems.

• Backend Services & APIs

Build and maintain backend services and RESTful APIs in Node.js/TypeScript and/or Python, with clean service boundaries, well-designed data contracts, and reliable integrations across the product.

• Data Modeling & Persistence

Design and evolve schemas in PostgreSQL (and document stores where appropriate); write performant queries, manage migrations, and tune for K-12-scale data volumes.

• AI/LLM Integration

Integrate Claude, OpenAI, and other model providers into product surfaces; build prompt orchestration, retrieval (RAG), function/tool calling, and agentic workflows that power Eddie.

• Authentication, Security & Privacy

Implement secure authentication (OAuth, JWT, SSO), role-based access controls, and data-privacy safeguards aligned with FERPA, COPPA, and SOC 2-style controls required for K-12 environments.

• Performance & Reliability

Optimize end-to-end performance-front-end load times, API latency, database query performance, and caching strategies-and instrument the stack with tools like Sentry, Datadog, Flipper, Hermes, and Firebase Performance Monitoring.

• Testing & Debugging

Write and maintain unit, integration, and end-to-end tests across the stack using Jest, Testing Library, Playwright, and backend test frameworks to ensure stability and regression protection.

• Version Control & CI/CD

Use Git, participate in code reviews, and own CI/CD pipelines for web, mobile, and backend services using GitHub Actions, Expo EAS, Fastlane, and cloud deployment (AWS, GCP, or Vercel).

• Code Quality & Scalability

Write clean, maintainable, and testable code while participating in code reviews and shaping best practices that support long-term scalability across backend services, web, and mobile platforms.

• Cross-Functional Collaboration

Work in agile sprint cycles alongside product managers, designers, and fellow engineers.

• Accessibility (a11y) Compliance

• 3+ years of full stack development experience building and shipping production-grade applications across web and mobile

• Strong front-end expertise in React.js, Next.js, React Native, TypeScript, JSX/TSX, and modern JavaScript (ES6+)

• Solid backend expertise in Node.js/TypeScript (Express, NestJS, etc.) and/or Python (FastAPI etc.), including designing and maintaining RESTful APIs

• Hands-on experience with relational databases (PostgreSQL preferred), schema design, and query performance; familiarity with document stores (MongoDB) and caching layers (Redis) a plus

• Experience integrating AI/LLM providers (Anthropic, OpenAI, etc.) via prompt engineering, RAG, function/tool calling, or agentic workflows

• Working knowledge of cloud infrastructure (AWS, GCP, or Vercel), containerization (Docker), authentication patterns (OAuth, JWT, SSO), and CI/CD pipelines (GitHub Actions, Expo EAS, Fastlane)

• Strong skills in mobile-first responsive design, accessibility (a11y) best practices, and automated testing (Jest, Testing Library, Playwright); passion for clean, maintainable code and continuous learning across the full stack

• Strong engineering fundamentals and a demonstrated ability to learn new stacks quickly

• Comfortable in an early-stage environment: ambiguity, shifting priorities, and owning work end-to-end

Desired Qualifications

• Bachelor's degree in Computer Science, Software Engineering, or a related field (or equivalent hands-on experience)

• 3-5+ years in full stack engineering roles with live production deployment across web and/or mobile

• Direct experience building AI- or LLM-powered applications is a strong plus

We're looking for an experienced Full Stack Engineer to join our early-stage, venture-backed team and own product development end-to-end-from backend services, data models, and AI integrations to the polished web and mobile interfaces our users rely on every day. From first click to final acceptance letter or first job offer, you'll design APIs, model data, integrate large language models, and ship accessible, high-performance UIs that shape how users feel, learn, and succeed. We're in the middle of the most significant restructuring of education and workforce in a generation. AI isn't just changing jobs; it's changing which degrees matter, which skills compound, and which paths actually lead somewhere. The rules students were told to follow five years ago no longer apply. And the people navigating this shift first are 16-24 year olds, the fastest-growing segment of the US workforce and the largest cohort entering higher education. They're making big decisions: where to go to college, what to study, whether to go at all, what trade to learn, what their first job should be, on a landscape that's being rewritten in real time. But every existing tool was built for someone else. LinkedIn was built for 35-year-old professionals. Indeed was built for corporate HR. Current college and career readiness tools are built for tracking, not for guiding. No one built the infrastructure for this cohort, this moment. That's what EduPolaris AI is building. Two products, one continuum: ? Eddie Education (https://edupolaris.ai): an agentic AI-powered college and career readiness platform to drive college and career readiness at scale in the context of each school. ? Eddie Jobs (https://eddiejobs.ai): An agentic AI-powered job application agent to bridge the last mile between workforce readiness to an actual job placement in the hyper-local, skills-aligned job market. We'd love to invite you to join us to help build it. EduPolaris AI is backed by the Harvard Alumni Entrepreneurs Accelerator and Pegasus Tech Ventures. Join a mission-driven startup transforming the college and career journey through cutting-edge AI, making the process more equitable, efficient, and empowering for students, families, and educators worldwide. Work alongside a world-class team from Harvard, Amazon, Disney, and more. Own what you build, shape a category-defining product, and grow with a company redefining what guidance means in education.
