Subject believes the current education system is failing millions of students due to a lack of technology to truly personalize learning at scale. The company aims to build AI infrastructure to make personalized education accessible to every student.
Requirements
- 7+ years of backend engineering excellence, with 3+ years at Staff/Principal level solving complex distributed systems challenges
- Deep Node.js expertise - You've built production systems that push the runtime to its limits
- Polyglot architecture experience - Production systems in Go, Rust, Elixir/Erlang, or modern Java. You know when Node isn't enough and can architect multi-language solutions for optimal performance
- PostgreSQL mastery - Complex schema design, query optimization, and scaling strategies for educational data
- AI/ML implementation - You've shipped LLMs and ML models to production, understanding both the possibilities and limitations
- Distributed systems architecture - Experience with systems serving millions of concurrent users with real-time requirements
- Cloud-native development (GCP preferred) - Microservices, event-driven architectures, and container orchestration at scale
Responsibilities
- Design adaptive learning systems that process 100M+ learning interactions daily, understanding patterns that human teachers might miss
- Build AI orchestration that can simultaneously personalize education for millions while maintaining <0.1% error rates
- Create intelligent content delivery systems that know exactly when a student needs encouragement, a different explanation, or a challenge
- Develop AI safety and governance protocols that protect student data while enabling breakthrough personalization
- Architect systems that learn from every interaction, making education better for the next student
- Build real-time assessment engines that understand not just what students know, but how they think
- Create knowledge graph systems that connect concepts across subjects in ways students intuitively understand
Other
- Partner with education researchers to translate pedagogy into scalable technology
- Work directly with teachers to understand classroom realities and build solutions that actually work
- Collaborate with students to ensure our technology speaks their language
- Contribute to open-source educational tools that lift the entire industry
- Publish research that advances the field of AI in education
