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.
