    Build new platforms and improve existing systems to enable millions of users to discover and consume relevant library content

  • Integrate and work with third-party API solutions to augment BiblioCore functionality

  • Champion AI-first development practices across the team, including the safe, effective integration of AI into our products and workflows, and helping establish the standards and judgment that ensure we move fast without sacrificing quality

  • Practice spec-driven development with coding agents: turning requirements into clear, testable specifications that agents can execute against, and reviewing agent output with a senior engineer's judgment

  • Design and champion agentic workflows across the SDLC, applying AI agents to planning, coding, code review, testing, documentation, and operations, and helping the team adopt the ones that prove their value

  • Use AI coding assistants and coding agents (e.g., Claude Code, Amazon Q, Copilot, or similar LLM-powered tools) to streamline workflows, generate high-quality code, and enhance productivity

  • Guide the technical direction for technical initiatives to account for scalability, resiliency, quality and security of BiblioCore

  • Take ownership for the design, development, and operationalization of features and systems

  • Tackle tech debt at the right times for faster feature delivery

  • Strong theoretical foundation in data structures, algorithms, and software engineering best practices

  • Demonstrated experience with AI-enabled development, including hands-on use of coding agents and AI coding tools, and helping teams adopt modern AI-assisted workflows

  • Experience with spec-driven development using coding agents: writing specifications that guide agents to correct, maintainable code, and iterating on specs rather than hand-editing agent output

  • Familiarity or hands-on experience with agentic workflows in the SDLC, such as agent-assisted code review, automated test generation, agent-driven refactoring, or AI-supported incident analysis

  • Extensive experience building RESTful API applications and consuming third-party API integrations

  • Experience debugging and optimizing large-scale, multi-threaded systems

  • Have a mindset for end to end ownership of services
