Senior Data Engineer

•       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

•       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

•       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

•       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

•       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

Qualifications

•       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

•       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
