You are equally comfortable whiteboarding a system architecture with stakeholders and writing production code the same afternoon. You have genuine curiosity about the why and what behind every problem - not just the how - and you thrive in fast, ambiguous environments where creative thinking and execution speed both matter., Required * 4+ years of professional software or data engineering experience, including hands-on solution design and architecture contributions * Experience designing and delivering end-to-end data and AI systems - from requirements through deployment - with clear documentation and stakeholder communication * Hands-on experience building AI agents, including defining agent skills, tool use, memory, and multi-step reasoning * Working knowledge of MCP (Model Context Protocol) - including building or consuming MCP servers to connect agents with external systems * Experience with agentic frameworks such as LangChain, LangGraph, AutoGen, CrewAI, or Semantic Kernel * Strong hands-on experience with data engineering: pipelines, ETL/ELT, data modeling, SQL and NoSQL databases * Proficiency in Python * Experience with cloud platforms (AWS, Azure, or GCP) and modern data stack tooling * Exceptional communication and interpersonal skills - you can earn trust quickly, navigate ambiguity, and drive alignment across diverse teams * Comfort working in fast-paced environments with shifting priorities and high ownership expectations Preferred * Experience with RAG architectures, vector databases (Pinecone, Weaviate, pgvector), and semantic search - including building end-to-end data pipelines that chunk, embed, and index unstructured content for retrieval * Familiarity with prompt engineering, fine-tuning, and LLM evaluation techniques * Experience with agent observability and tracing tools (LangSmith, Arize, Weights & Biases, or similar) * Experience with AWS AgentCore - building, deploying, and operating agents on the platform * Knowledge of data orchestration tools (Airflow, Prefect, or dbt) * Experience with containerization and CI/CD practices (Docker, Kubernetes, GitHub Actions) * Background in real estate, financial services, or other data-intensive enterprise domains * Experience facilitating technical discovery workshops, design sprints, or architecture reviews * Contributions to open-source agentic or data projects, or a portfolio demonstrating rapid, creative problem-solving This position does not provide visa sponsorship. Candidates must be authorized to work in the United States without sponsorship. ## Description As a Forward Deployed Data Engineer, you will be embedded directly with product, program, and engineering teams to design, architect, prototype, and deploy data-driven solutions that solve high-priority business problems. This is not a traditional engineering role with long delivery cycles. You will be expected to go from concept to working prototype in days, not months, while maintaining enterprise-grade standards for quality, security, and scalability., Solution Design & Architecture * Drive solution design for complex, cross-functional data and AI problems - from initial discovery through to technical blueprint * Define and communicate architecture decisions, trade-offs, and delivery approaches to both technical and non-technical audiences * Design scalable, modular systems that balance the need for speed with enterprise standards for reliability, security, and maintainability * Participate in architecture reviews and Critical Design Reviews (CDRs), ensuring alignment with enterprise patterns and platform standards * Create clear technical documentation: architecture diagrams, data flow maps, API contracts, and solution briefs Rapid Prototyping & Solution Delivery * Design and deliver working prototypes for complex data and AI problems within compressed timeframes, often days to weeks * Bring genuine curiosity to every engagement - deeply understanding the business case, problem context, and constraints before converging on a solution * Balance speed of delivery with enterprise standards - your prototypes are production-ready, not throwaway * Continuously iterate on solutions based on direct feedback from product managers, program leads, and end users AI Agent Development & Agentic Systems * Design, build, and deploy AI agents and multi-agent systems that automate complex workflows end-to-end * Develop and maintain agent skills - discrete, reusable capabilities that compose into larger agentic pipelines * Implement and extend MCP (Model Context Protocol) servers and clients to connect AI agents with enterprise tools, APIs, and data sources * Build agent orchestration layers using frameworks such as LangChain, LangGraph, AutoGen, CrewAI, or Semantic Kernel * Design evaluation harnesses, guardrails, and monitoring pipelines to ensure agent reliability and safety in production * Stay current with the rapidly evolving agentic AI landscape and proactively introduce new techniques and tooling to the team AI & Data Engineering * Build and deploy AI-powered features and pipelines that automate workflows, surface insights, and enhance decision-making * Design and implement scalable data pipelines, APIs, and backend services that serve both internal tools and customer-facing products * Integrate LLMs, RAG systems, and ML models into production data workflows * Own data modeling, transformation, and quality across the solutions you deliver Collaboration & Stakeholder Engagement * Embed directly with product, program, and engineering teams to co-define problems and co-deliver solutions * Contribute to technical direction and help build alignment across teams through strong communication and collaboration * Communicate complex technical concepts clearly to non-technical business stakeholders - in writing, in meetings, and in presentations * Support and mentor junior engineers, sharing patterns and practices for agentic development, prompt design, and rapid delivery * Foster a collaborative, low-ego team culture where speed and quality go hand in hand, For candidates in the United States, please see a full copy of our Equal Employment Opportunity policy here.
