Senior GIS Engineer

JLL empowers you to shape a brighter way. Our people at JLL are shaping the future of real estate for a better world by combining world class services, advisory and technology for our clients. We are committed to hiring the best, most talented people and empowering them to thrive, grow meaningful careers and to find a place where they belong. Whether you’ve got deep experience in commercial real estate, skilled trades or technology, or you’re looking to apply your relevant experience to a new industry, join our team as we help shape a brighter way forward.

The Senior Software Engineer develops, tests, documents, and maintains robust, scalable full stack applications using modern technologies including AI, cloud platforms, GIS, and Dev Sec Ops  practices. This role works across JLL’s geospatial and enterprise data platforms on problems such as geocoding, data matching, and cross-platform data alignment.

• Design & Delivery Independently design and implement complex solutions — geospatial data pipelines, geocoding and matching services, and the interfaces between them — with testing, monitoring, and data-quality validation built in
• Solve medium to high complexity problems, including reconciling records across systems with differing identifiers and data models
• Bring new perspectives to existing solutions, applying AI and automation to improve both products and development practices

• Work with product and business teams to influence solution decisions, translating business needs into technical requirements
• Apply enterprise-first thinking: contribute & build shared capabilities and data contracts that serve multiple platforms and teams

• Lead medium projects with manageable risks and serve as a trusted opinion in your product area
• Coach less experienced engineers and deliver knowledge-sharing sessions
• Use storytelling to explain difficult concepts and build consensus across platform teams and business stakeholders

We don’t expect any single candidate to arrive with every skill listed below. If you’re strong on full stack development and have depth in either GIS or applied AI, we want to hear from you — the rest is learnable on the job.
