As a member of the Language Engineering team, you will:
-
Identify bad code practices in Ruby and write new analyzers to detect them.
-
Improve the coverage of automatically fixable issues.
-
Ensure fewer false-positives are reported by the analyzer.
-
Work on the internal tools that support analysis runtimes.
-
Contribute to open-source static analysis tools.
