Job Description

Cogniify is building production-grade Generative AI applications and is hiring a hands-on engineer to design, build, and deploy systems that power LLM-powered products. This role in the San Francisco Bay Area (hybrid) focuses on core capabilities like RAG pipelines, intelligent agent workflows, and reliable integration with internal tools, external APIs, and enterprise applications.

You will work across the full lifecycle, from model and framework selection to evaluation, safety guardrails, deployment, and ongoing LLMOps monitoring.

Key Responsibilities

Design and develop scalable LLM-powered applications using Python.
Build RAG pipelines including document processing, embeddings, vector databases, semantic search, and reranking.
Develop AI-agent and multi-agent workflows with tool calling, memory, orchestration, and human approval steps.
Integrate LLMs with internal systems, external APIs, databases, and enterprise applications.
Evaluate and select foundation models based on accuracy, latency, cost, security, and business needs.
Improve prompt quality, retrieval accuracy, response time, and token usage.
Implement safety guardrails, output validation, access controls, and fallback mechanisms.
Build automated evaluation frameworks to assess response quality, hallucination, relevance, and reliability.
Containerize applications with Docker and deploy on AWS, Azure, or GCP.
Apply monitoring and LLMOps practices for model performance, cost, latency, errors, and production usage.
Collaborate with product, engineering, and business teams to translate requirements into reliable AI solutions.
Document technical architecture, design decisions, APIs, and operational processes.

Requirements

Bachelor's or Master's degree in Computer Science, Engineering, or a related discipline, or equivalent practical software-development experience.
6-9 years of professional software-development experience, including strong hands-on experience with Python.
Experience developing backend services and integrating REST APIs.
Hands-on experience building LLM or Generative AI applications.
Practical experience implementing RAG using embeddings, semantic search, and vector databases.
Experience with LangChain, LangGraph, LlamaIndex, or a comparable LLM application framework.
Experience integrating foundation models through APIs such as OpenAI, Anthropic Claude, Gemini, or Azure OpenAI.
Working knowledge of vector databases including Pinecone, Weaviate, Milvus, Qdrant, Chroma, FAISS, or pgvector.
Experience with Docker and deployment on at least one of: AWS, Azure, or GCP.
Understanding of prompt engineering, hallucination reduction, output validation, and LLM evaluation.
Strong understanding of software engineering practices including Git, testing, debugging, and clean code.
Ability to communicate technical solutions clearly to both technical and non-technical stakeholders.
