Bounteous - Full Stack Developer - Generative AI

About The Role We are looking for a talented and passionate AI Generative Full Stack Developer to join our growing engineering team. You will be responsible for designing, building, and deploying intelligent AI-powered applications combining cutting-edge generative AI capabilities with robust full stack development using Python and React. You will work at the intersection of AI research and product engineering, turning LLM capabilities into real-world, production-ready features.

Key Responsibilities

• Design and develop AI-powered full stack applications using Python (backend) and React (frontend).
• Build and maintain agentic frameworks and LLM pipelines using tools like LangChain, LlamaIndex, or custom implementations.
• Integrate generative AI APIs (OpenAI, Anthropic Claude, Gemini, etc.) into scalable web applications.
• Develop RESTful and GraphQL APIs to connect AI backends with React frontends.
• Implement RAG (Retrieval-Augmented Generation) systems using vector databases (Pinecone, Weaviate, ChromaDB).
• Build and optimize prompt engineering workflows and evaluation pipelines.
• Collaborate with product, design, and data science teams to ship AI features end-to-end.
• Write clean, testable, and well-documented code.
• Monitor, debug, and optimize AI model performance in production.
• Stay current with the rapidly evolving generative AI landscape.

Required Skills & Experience

• Claude API & Anthropic SDK proficiency Hands-on experience with the Messages API, tool use / function calling, system prompt design, and model selection trade-offs (Sonnet vs. Opus vs. Haiku). Familiarity with context window management and token budgeting.
• Agentic loop architecture Ability to design reliable multi-step agent loops: tool orchestration, retry logic, error recovery, and knowing when to stop or escalate rather than loop indefinitely.
• Tool/MCP integration Experience building and connecting tools (internal APIs, databases, external services) via Anthropic’s tool use schema or MCP servers, including input validation and graceful failure handling.
• Prompt engineering & evaluation Skilled at structured prompting (system prompts, few-shot examples, XML tagging), and building prompt eval harnesses to measure output quality, regression-test changes, and tune instructions systematically.
• Observability & auditability Knows how to log full agent traces (inputs, tool calls, intermediate outputs, final responses) in a structured, queryable format. Experience with tools like LangSmith, Braintrust, Helicone, or custom tracing pipelines.
• Measurement & KPI design Can define and instrument meaningful agent metrics: task completion rate, tool call accuracy, hallucination rate, latency per step, cost per run, and human-in-the-loop escalation rate. Connects agent telemetry to business outcomes.
• Human-in-the-loop & guardrails Understands when to inject human review checkpoints, how to design approval gates for high-stakes actions, and how to implement input/output guardrails (content filtering, schema validation, confidence thresholds).
• Cost & latency optimization - Experience profiling and reducing inference costs through prompt caching, batching, streaming, and appropriate model tiering without sacrificing reliability.
• Security & data handling - Awareness of prompt injection risks, credential/secret hygiene in agentic contexts, PII handling, and least-privilege design when agents have access to real systems or external APIs.
• Software engineering fundamentals Strong async Python (or TypeScript), testing discipline (unit + integration tests for agent components), CI/CD, and the ability to decompose complex agent systems into maintainable, modular code.

Ai/Llm

• Hands-on experience with LLM APIs (OpenAI, Anthropic, Cohere, or similar).
• Experience building agentic systems (tool use, memory, multi-step reasoning).
• Familiarity with prompt engineering techniques (chain-of-thought, few-shot, RAG).
• Understanding of fine-tuning and model evaluation concepts.

Backend (Python)

• Strong proficiency in Python 3.x.
• Experience with FastAPI or Django / Flask.
• Working knowledge of SQL and NoSQL databases (PostgreSQL, MongoDB, Redis).
• Familiarity with async programming and background task queues (Celery, RQ).
• Experience with Docker and deploying to cloud platforms (AWS, GCP, or Azure).

Frontend (React)

• Strong proficiency in React.js and modern JavaScript (ES6+).
• Experience with TypeScr…
