Strong expertise in Java with a focus on production backend code.
5+ years of software development experience or equivalent ownership of complex systems.
Experience with enterprise backend systems, including business rules and evolving requirements.
Proficient in structured data formats like XML schemas and validation rules.
Excellent problem-solving skills for debugging across services and integration points.
Ability to work independently while coordinating with multiple stakeholders.
Effective written communication for design rationale and status updates.
Patience and temperament for incremental improvements in legacy systems.
Responsibilities
Own end-to-end vertical slices from requirements to release in complex backend systems.
Modernize and refactor existing code for improved structure and maintainability without major rewrites.
Deliver features and fixes that align with product needs while respecting existing architecture.
Integrate with operational partners on shared data and workflows, clarifying ownership and supporting reliable production runs.
Primarily work in Java production services, with contributions to Python and bash scripting as needed.
Collaborate asynchronously with clear documentation and feedback, while maintaining alignment with team priorities.
Participate in code and design reviews, mentoring peers through example and constructive feedback.
Leverage AI-assisted development tools to enhance delivery on legacy codebases.
Benefits
Collaborative work environment with a focus on technical guidance and problem-solving.
Opportunities for professional growth through mentoring and code reviews.
Exposure to modern development tools and practices, including AI-assisted technologies.
Flexibility in working style, accommodating asynchronous communication.
Engagement with complex, meaningful projects that impact enterprise systems.
Full Job Description
The job details are as follows: As a Senior Software Engineer, you will be responsible for independently designing, developing, and testing complex software programs and systems. You will collaborate with team members to solve problems, provide technical guidance, and ensure the delivery of high-quality software solutions. You will also collaborate with product managers, designers, and other engineers to define, refine, and implement features and enhancements.
Responsibilities:
Own vertical slices end-to-end-from understanding requirements through design, implementation, test, and release-in complex backend systems with substantial business logic and legacy constraints.
Modernize and refactor in place: improve structure, clarity, and maintainability without requiring a big-bang rewrite; ship incrementally with attention to production risk.
Deliver features and fixes that meet product and partner needs while respecting existing architecture, data contracts, and operational dependencies.
Integrate with operational partners on shared data and batch workflows: clarify ownership boundaries, implement behavior changes in application code, and support handoffs that keep production runs reliable.
Work primarily in Java production services; contribute to Python and bash scripting paths where application logic touches script-heavy batch or ingest workflows.
Collaborate asynchronously with clear written design notes, review feedback, and stakeholder updates; work independently on assigned slices while staying aligned with team priorities.
Participate in code and design review; mentor peers informally through example and constructive feedback.
Leverage and explore AI-assisted development tools (e.g., GitHub Copilot, Cursor, code generation, smart testing) where appropriate; help assess what actually improves delivery on legacy codebases.
Maintain awareness of security, data governance, and quality standards in an enterprise context.
Qualifications:
Demonstrated professional strength in Java: shipping, maintaining, and evolving production backend code-not occasional or peripheral use.
5+ years of software development experience, or equivalent depth shown through ownership of complex production systems (we flex on years when the work speaks for itself).
Meaningful experience in complex domain or enterprise backend systems-business rules, evolving requirements, and long-lived codebases-not only greenfield services.
Comfort reading and working with structured data formats, including XML schemas and validation rules common in metadata and authority workflows.
Strong problem-solving and debugging in production: tracing issues across services, scripts, and integration points.
Working style
Demonstrated ability to own slices independently, coordinate with multiple stakeholders, and drive clarity when requirements are incomplete or ambiguous.
Effective async communication: written design rationale, review comments, and status updates that keep distributed collaborators aligned.
Temperament for incremental improvement in legacy systems-patience for context-gathering, careful change, and operational follow-through.
Working Conditions: Normal office environment.
About OCLC
The Buckeye Manufacturing Company was a company founded in 1884 by John William Lambert and his family members originally to manufacture horse drawn buggy parts in Union City, Ohio. The enterprise started with $2,000 and six men and some helper boys. The company got involved in making tools and one early horseless carriage automobile.
Lambert and his family members in 1893 moved the Buckeye Manufacturing Company to Anderson, Indiana. The company at that time brought in a horse drawn buggy harness pole firm owned by one of the Lambert family members. In time the Buckeye Manufacturing Company founded automobile related subsidiary companies under it led by Lambert, some of which were the Union Automobile Company, the Lambert Automobile Company, and the Lambert Gas and Gasoline Engine Company.
