JREQ204795Job DescriptionAs a Staff Software Engineer II at KeyCite, you will lead complex, business-critical engineering initiatives from architecture through production. You will modernise established platforms while maintaining the reliability that customers depend on, and you will set technical direction across teams.

Key Responsibilities* Lead complex engineering initiatives, designing and delivering end-to-end solutions for large-scale, business-critical systems.* Modernize core KeyCite platforms and services using modern architectural patterns without disrupting critical customer-facing products.* Design distributed services, processing systems and APIs that meet demanding standards for performance, availability, scalability and maintainability.* Lead architecture and design decisions across complex systems, balancing near-term delivery with long-term sustainability.* Build scalable data-processing capabilities for large volumes of structured and unstructured legal content and metadata.* Identify architectural constraints and systematically simplify, modernize or replace components, while enabling teams to keep delivering business value.* Assess emerging technologies and architectural approaches based on measurable improvements to scalability, reliability, developer productivity and customer outcomes.* Champion modern practices across design, development, testing, observability, security, deployment and operational ownership.* Establish measurable standards for quality, reliability,



security and maintainability.* Work across engineering teams and with Product and Architecture to solve problems that span organizational and system boundaries.* Partner with engineering and product leadership on long-term technical strategy.* Establish patterns and standards that are adopted beyond your immediate team.* Act as the technical authority for complex architecture and engineering decisions.* Mentor engineers and develop senior engineering talent.* Lead technical discussions and design reviews, and raise the engineering bar across the organization.* Communicate complex technical concepts clearly to senior technical and non-technical stakeholders.* Translate business and product requirements into durable technical architectures.* Make pragmatic trade-offs between feature delivery, modernization and technical debt.* Identify opportunities to reuse platform capabilities rather than building bespoke solutions.* Connect technical investment to measurable product and business outcomes.* Recognize the importance of reliability and accuracy in systems that support professional research.

Required Qualifications* 6+ years of experience in designing and delivering complex production software systems.* Deep expertise in backend and distributed systems engineering.* Strong experience with cloud-native architectures, preferably on AWS.* Experience designing APIs,



services and event-driven architectures.* Experience with large-scale data processing and data pipelines.* Strong understanding of system reliability, scalability, performance and observability.* Experience modernizing complex legacy or long-lived production systems without disrupting existing customers.* Strong programming skills, ideally in Java and/or Python.* Experience with up-to-date 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 large-scale metadata or knowledge systems.* Experience with graph or relationship-oriented data models.* Experience building platforms or services consumed by multiple products and engineering teams.* Experience operating highly available, business-critical systems.* 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.#LI-GK1
