Together we make breakthroughs possible.

At OCLC, we build technology with a purpose: to connect libraries and make knowledge accessible worldwide, because we believe that what is known must be shared. Our teams work with complex global datasets, AI and machine learning, hybrid cloud solutions, and other technologies that connect people and organizations to the information they need. We value the power of unique perspectives and experiences to unlock innovation.

At OCLC, your ideas matter, whether you have two years of experience or 20. You'll learn, create, and problem-solve with technologists, product developers, librarians, researchers, marketing pros, and support teams around the world.

Access Checker is a green-field service within OCLC focused on harvesting and evaluating the accuracy of eResource links at large scale - helping libraries identify access issues earlier and improving the reliability of knowledge discovery for end users.

We are looking for a Software Engineer who enjoys solving practical engineering problems, building reliable services, and learning within a collaborative team. You will contribute to the development of a high-throughput link-harvesting and evaluation platform, working across the wider OCLC ecosystem to deliver software that is scalable, maintainable, and operationally robust.

You'll join a small, geographically dispersed team that is encouraged to work independently, share ideas, and collaborate closely to deliver high-quality software through a fully CI/CD approach. The team is also adopting an AI-first approach to design and development-both through AI-assisted engineering workflows and through the thoughtful use of ML/LLMs to improve link-evaluation quality and efficiency.

• Design, implement, test, and support software components for the Access Checker system.
• Develop new features and enhancements for a high-throughput link-harvesting and evaluation pipeline.
• Write clean, maintainable, well-tested Java/Spring code and contribute to a reliable production service.
• Investigate, debug, and resolve technical issues, including performance, reliability, and integration concerns.
• Work with team members to design solutions that integrate cleanly with other OCLC systems while minimising performance and resource impact.
• Participate in technical design discussions, code reviews, and team problem-solving.
• Contribute to code quality standards, including testability, readability, observability, and operational readiness.
• Use AI-assisted development tools and contribute to the team's use of ML/LLMs where appropriate to improve evaluation accuracy, efficiency, and maintainability.
• Collaborate with product managers, designers, and engineers to refine and deliver features.
