* Experience with modern engineering practices, including automated testing, CI/CD, infrastructure automation and production monitoring.




* Demonstrated ability to influence architecture and technical direction beyond an individual team.
* Ability to independently navigate ambiguous, highly complex technical problems.
* Strong communication skills, with the ability to explain architectural trade-offs to technical and non-technical stakeholders.
* Experience mentoring senior engineers and raising technical standards across teams. Preferred Qualifications* Experience with high-volume content, publishing, search or information-processing platforms.
* Experience with search and information retrieval technologies.
* Experience with graph or relationship-oriented data models.
* Experience building platforms or services consumed by multiple products and engineering teams.
* Exposure to legal technology, professional information or other domains where accuracy, provenance and reliability are critical.
* Familiarity with AI-enabled applications and the backend and data infrastructure that supports them.#Hybrid Work Model: We’ve adopted a flexible hybrid working environment for our office-based roles while delivering a seamless experience that is digitally and physically connected.
