Role Overview:
We are seeking a Senior Full Stack Engineer to lead the development of high-performance, AI-driven web applications. You will be responsible for building responsive React frontends and a high-throughput backend architecture using Python (FastAPI) and Rust.
A key focus of this role will be the integration of Natural Language Processing (NLP) and Generative AI features into our product ecosystem—leveraging Rust for performance-heavy inference tasks and Python for rapid AI prototyping and orchestration.
Key Responsibilities
- End-to-End Development: Design and implement scalable features using React (frontend), FastAPI (orchestration), and Rust (performance).
- AI Integration: Build and deploy AI-powered features such as semantic search, automated summarization, and agentic workflows.
- Hybrid Backend Architecture: Maintain a dual-backend strategy—using Python for its rich AI/ML ecosystem and Rust (via PyO3/Maturin) for high-speed data processing and model inference kernels.
- Modern UI/UX: Create sophisticated user interfaces that effectively visualize AI outputs and handle complex user-agent interactions.
- Mentorship & Best Practices: Lead architectural discussions, promote type safety across the stack, and mentor junior engineers in modern AI-integrated development.
Technical Requirements:
Frontend (Modern React Stack)
- Core: Expert-level React (18/19+), Javascript/ TypeScript, and ESNext.
- Frameworks: Experience with Next.js (App Router), React Server Components (RSC), Node.js frameworks with REST/GraphQL APIs.
- Latest Tools: Proficiency with Vite, Tailwind CSS, and TanStack Query.
- AI Interaction: Experience building "streaming" UIs for LLM responses (e.g., Vercel AI SDK).
Backend (Python & Rust)
- Python Mastery: Expert in Python 3.12+ and FastAPI. Proficient in asynchronous programming and Pydantic v2.
- Rust Excellence: Proficiency in Rust for building low-latency services or extensions. Familiarity with crates like Axum, Tokio, and Serde.
- The Bridge: Experience using PyO3 or Maturin to optimize Python applications with Rust.
- Data: Advanced PostgreSQL (relational) and Redis (caching).
Mandatory Skills:
- Python, Fast API, JavaScript &React
Good to Have" (AI & NLP Skills)
- NLP & LLMs: Experience integrating Large Language Models (GPT-4, Claude 3.5/4, Llama 3) via APIs or local hosting (Ollama/vLLM).
- AI Frameworks: Familiarity with orchestration tools like LangChain, LlamaIndex, or CrewAI for building agentic workflows.
- Vector Databases: Hands-on experience with Pinecone, Weaviate, Chroma, or Milvus for Retrieval-Augmented Generation (RAG).
- ML Libraries: Basic knowledge of PyTorch or Hugging Face Transformers for fine-tuning or implementing NLP models (Sentiment Analysis, NER, etc.).
- AI Tooling: Experience using AI-first development tools like Cursor, GitHub Copilot, or Windsurf to accelerate the development lifecycle.
Preferred Qualifications
- Experience with WebAssembly (Wasm) to run Rust/AI logic directly in the browser.
