We move fast, think big, and deliver production-grade platforms that transform how JLL operates - combining deep technical expertise with a relentless focus on solving real problems for real users.

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.

You bring a strong combination of skills: solution design and architecture experience, deep hands‑on engineering across data and AI agents, and the interpersonal skills to earn trust, drive alignment and collaborate effectively across teams. 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.

• 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 time frames, 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 Lang Chain, Lang Graph, Auto Gen, CrewAI, or Semantic Kernel
• Design evaluation harnesses, guardrails, and monitoring pipelines to ensure agent reliability and…
