For March 2025, Shopify/job-iteration delivered a focused enhancement for Sorbet-based type safety in background jobs. The team implemented generic job handling and RBI generation by updating the job_iteration.rb logic to detect the number of generic type members and to dynamically construct the return type for perform_later to include those generics. This work includes new tests validating RBI generation for jobs with one or multiple generic variables, increasing confidence in type accuracy for delayed jobs. Impact: Improves type-safety and reliability of delayed job execution, reducing runtime errors and enabling safer use of generic jobs across services. No major defects were reported for this repository this month. Tech/skills demonstrated: Ruby, Sorbet type system and compiler extension, RBI generation, test-driven development, and targeted code-change review.
