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.
** Role Overview
** As a Staff Software Engineer on the Legal Technology team, you will lead the design and implementation of complete features spanning React front ends, Python and Node.js backend services, data layers, and cloud deployment pipelines on AWS or Azure. You will build the systems that support JLL’s Legal and Anti-Financial Crime (AFC) functions, where accuracy, auditability, confidentiality, and data privacy are requirements rather than nice-to-haves.

This is a senior, hands-on technical role. You will discover problems, determine their criticality, and drive your own projects to a successful conclusion, while setting engineering standards and mentoring other engineers. You will use AI coding assistants as part of your daily workflow, and you will help the team move from AI-assisted development to AI-enabled products, including agent-based workflows that keep humans in control of consequential decisions.
** Key Responsibilities
**** Technical Leadership & Architecture
*** Lead the design and implementation of end-to-end features across the React front end, Python/Node.js services, data stores, and cloud (AWS or Azure) deployment pipeline. Own features from discovery through production support.
* Perform solution design for ill-defined or cross-domain problems, accounting for integration with existing Legal and AFC systems, data lineage, and long-term maintainability.
* Define architecture patterns, reference designs, and technical standards that other engineers on the team adopt.
* Design systems with security, confidentiality, and auditability built in: role-based access control, data segregation, immutable audit trails, encryption, and retention controls appropriate for legal and regulated data.
* Set up solution structure, CI/CD, infrastructure as code, and Dev Sec Ops  practices for new and modernized applications.
** Development & Implementation
*** Work with product owners, Legal and AFC stakeholders, and technical leads to design new products and enhancements, and participate in analysis, coding, and testing.
* Use AI coding assistants and enterprise AI tooling to rapidly develop, test, and iterate on production-quality code, applying sound judgment on when to trust AI output and when to intervene.
* Deliver robust implementations that follow best practices with minimal feedback in code review, and improve related code while you are in it.
* Build and maintain data pipelines and integrations across internal systems, third-party…
