Full Stack Software Engineer - Frontend Focus

We're seeking a talented Full Stack Software Engineer with a strong frontend focus to join our engineering team. You'll work on our AI-powered data processing platform, building intuitive interfaces for complex document analysis, real-time collaboration, and data visualization workflows.

About Us

We're a VC-backed, AI-native startup based out of Berkeley, California, building the next generation of industrial AI systems. Our team includes Berkeley AI researchers, ex-FAANG engineers, and product leaders who've scaled frontier software and AI systems at Fortune 10s. We're already working with major US and global players in Oil & Gas, Chemicals, and broader Industrial sectors — and just getting started.

• Full Stack Capabilities:
• Proficiency in Python (FastAPI) or Node.js (NestJS)
• Experience with PostgreSQL and ORMs (SQLAlchemy, TypeORM)
• Understanding of RESTful API design and WebSocket communication
• Familiarity with Docker and containerized deployments

• Best Practices:
• Strong testing practices (Vitest, pytest, React Testing Library)
• Experience with CI/CD pipelines (GitHub Actions)
• Understanding of observability and monitoring (OpenTelemetry)
• Commitment to code quality (ESLint, TypeScript strict mode)

Nice to Have

• Experience with AI/ML integrations and LLM applications
• Knowledge of document processing and OCR technologies
• Familiarity with vector databases and semantic search
• Experience with WebRTC and real-time collaboration features
• Background in data visualization and scientific computing
• Experience with graph databases (Neo4j) and GraphRAG concepts

What You'll Work On

• Interactive Document Analysis: Build interfaces for AI-powered document parsing, including PDFs, engineering diagrams, and technical documentation
• Real-Time Collaboration: Implement WebRTC-based features for live document editing and annotation
• Data Visualization: Create sophisticated visualizations for complex data relationships, including network graphs and engineering diagrams
• AI Integration: Develop intuitive UIs for interacting with LLM-powered features and managing AI workflows
• Performance Optimization: Ensure smooth performance when handling large documents and complex visualizations

Our Development Process

• Small, focused pull requests following the "one thesis" rule
• Continuous deployment with staging environment validation
