We attract and retain the best talent by investing in our employees and empowering them to develop themselves and their careers. Experience the challenges, rewards and opportunity of working for one of the world’s largest providers of products and services to the global energy industry.\nThe Opportunity\nWe are building a platform that merges real-time physics, structured knowledge, and autonomous intelligence. We are looking for developers ready to tackle one (or more) of those challenges:\nIngestion: Handling massive streams of sensor data with minimal latency.\nIntelligence: Making LLMs deterministic and reliable within robust multi-agent systems.\nContext: Modeling complex ontologies to map thousands of physical assets.\nWhat You'll Do\nYou will join a high-performance team, contributing to designing and delivering Advanced Agentic AI Systems across the full stack - from data pipelines and knowledge graphs, through agent orchestration, to the interactive UI engineers and analysts use every day.\nCore Responsibilities\nGenAI & Autonomous Agents\n Build Autonomous Agents: Deploy stateful agents (using LangGraph) that plan tasks, query Knowledge Graphs, and execute tools without hallucinating.\nAdvanced RAG: Build Graph-RAG pipelines that combine semantic search with structured knowledge traversal for grounded answers.\nBuild agents capable of integrating with engineering tools, simulators, databases, and knowledge sources.\nCollaborate with domain experts to align agent behavior with technical expectations and constraints.\nImplement safeguards to ensure accuracy, traceability, and reliability of AI-generated outputs.\nContinuously optimize prompting, agent orchestration, and performance under real-world conditions.\n High-Performance APIs: Build low-latency Python services (FastAPI) to serve live data to frontend and AI models.\nRapid Delivery: Adopt a “deliver fast” mentality without compromising code quality, testing, or API design standards.\nFull-Stack & Visualization\nBuild interactive React-based AI chat assistant including canvas/dashboard views\nTechnology Stack & Desired Profile\nYou do not need to be an expert in every single tool, but you must be able to discuss technical trade-offs across the entire stack:\n GenAI: LangGraph, LangChain, LiteLLM, Azure OpenAI/Anthropic/Local SLMs, MCP (Model Context Protocol).\n Backend: Python 3.12+ (FastAPI), Kafka, Neo4j.\nFrontend: React, Angular 16+, TypeScript, RxJS, Plotly.js.\nData: Apache Airflow, Trino, Apache Iceberg, MinIO, Delta Lake, Polars/Spark.\n Infrastructure: Kubernetes (EKS/AKS/K3s/on-prem), Terraform, Hybrid Cloud.\nDesired Profile\nProblem Solver: You dig into logs to find the root cause of a data spike, a silent failure, or a disconnected node in a graph.\nModern Pythonista: You are up-to-date with modern Python async patterns and typing, ensuring code is high-performance and maintainable.\nYou understand Big O notation and how to optimize code for CPU/memory efficiency.\nFull-Stack Mindset: You move comfortably between backend services, agent orchestration, and frontend UI work, and can reason about trade-offs across the whole stack.\nQualifications\nMust Haves:\n GenAI: Practical experience building applications with LLMs, Agentic Frameworks (LangGraph), and Vector Databases.\n5+ years of experience in Python Backend development.\n2+ years of experience with modern frontend frameworks (React and/or Angular) and TypeScript. \nAdvanced English communication skills.\nComputer Science fundamentals: Data Structures and Algorithms.\nStrong experience building and documenting REST APIs (FastAPI).\nGood to Have:\n Agent Evaluation: Experience building eval pipelines for agentic systems (e.g., Lang Smith, Ragas, or custom harnesses) to test task success, groundedness, and hallucination rate.\n Streaming: Proficiency with Streaming Technologies (Kafka, Flink, Spark) and Time-Series Databases (TimescaleDB, InfluxDB).\n Graph: Hands-on experience with Graph Databases (Neo4j/Cypher), SQL database design, and Hybrid Search strategies.\nBackground in Heavy Industry, O&G, or IoT data (MQTT, OPC UA).\nExperience with Local LLMs (Ollama) for privacy-focused deployments.\nFamiliarity with Data Lineage or Metadata management.\nHalliburton is an Equal Opportunity Employer.
