\\n

\\n
and helps apply and improve the team\'s coding standards, tools, and best practices.
\\n
Provides informal guidance to junior engineers and contributes to onboarding and
\\n
knowledge sharing.

Applies computer science fundamentals - algorithm design, problem solving, complexity
\\n
analysis, and data structures - and growing experience with Big Data technologies to solve
\\n
business problems.

Uses AI-assisted development tools to work more effectively, applying good judgment to
\\n
review generated output for correctness, security, and quality.
