The Job Details are as follows:

The Principal Architect performs high level analysis and design of software programs and systems. Create, analyze, design, modify and test programs and systems. Architect and prototype systems.

Major responsibilities:

• Lead architecture for Public Library Software and the Resource Sharing domain: define target architecture, patterns, and standards for APIs, integration, data, search, and deployment.
• - Translate business needs into high-level designs and practical implementation plans; produce architecture artifacts and roadmaps.
• - Champion ideas and drive change — actively promote and advance strategic technical and product ideas, not just report on them.
• - Advocate for the business — balance technology leadership with a clear focus on business outcomes and user value.
• - Drive modernization efforts (microservices, cloud, CI/CD, containerization, API design) and guide migration decisions.
• - Design for non-functional requirements: availability, scalability, performance, security, resilience, observability, and operability across global deployments.
• - Own technical review and governance — participate in and lead design reviews; enforce architectural patterns and request/advise on exceptions with Enterprise Architecture.
• - Prototype and validate new technologies (search, indexing, big data, caching, streaming) to accelerate product innovation.
• - Work closely with Product Management to prioritize technical investments and articulate tradeoffs and risks.
• - Provide hands-on technical leadership: design, code and review critical components as needed; collaborate with engineering teams to unblock delivery.
• - Mentor and coach engineers and architects; contribute to hiring, performance management, and technical career development.
• - Reduce communication chaos — close gaps between teams, simplify messaging, and create clear channels for technical decisions.
• - Own the big picture — provide high‑level architectural direction rather than micromanaging implementation details.
• - Decisive yet empowering — make clear architecture decisions and enable teams to execute and make local choices.
• - Lightweight people management — provide leadership and mentorship without heavy managerial responsibilities.
• - Collaborate with integrations, support, security, and operations teams to ensure smooth production rollout and ongoing reliability.
• - Evaluate third‑party products, standards (NCIP, ISO, NISO, etc.), and vendor solutions relevant to resource sharing; represent the organization in relevant forums when requested.
• - Ensure security awareness — embed security considerations into architecture and design decisions.
• - Operate effectively under ambiguity — make progress and adapt when requirements or technologies are unclear or shifting.

Minimum qualifications:

• Master’s degree required plus 8 to 12 years experience at a high technical level of knowledge and experience. (Equivalent experience without a Master’s degree is 10 to 14 years experience at a high technical level of knowledge and experience.) 
• - Demonstrated experience designing and delivering large‑scale, highly‑available, distributed web systems (international deployments preferred).
• - Strong hands‑on background in modern backend technologies and languages (Java preferred; experience with JVM ecosystem, or equivalent in other languages).
• - Deep experience with service/API design (REST/GraphQL), integration patterns, message/streaming platforms (Kafka or similar), and event‑driven architectures.
• - Proven track record with cloud platforms and operational patterns (AWS/GCP/Azure), containers (Docker), orchestration (Kubernetes), CI/CD and infrastructure as code.
• - Strong data architecture experience: data modeling, indexing/search systems (Elasticsearch/Solr), caching strategies, and familiarity with big data toolsets (Hadoop/Spark/Cassandra or equivalents).
• - Strong orientation to non‑functional requirements: performance, capacity planning, reliability engineering, security and compliance (GDPR, etc.).
• - Excellent communication and stakeholder management skills; ability to present architecture to both technical and non‑technical audiences.
• - Experience mentoring and growing engineering teams; able to influence cross‑functional peers and senior leaders.
