• Deep expertise in Ruby on Rails and Java (our core backend languages).
• Strong frontend engineering experience with modern JavaScript frameworks, particularly React and TypeScript.
• Demonstrated experience with AWS cloud infrastructure.
• Domain expertise in logistics, routing, mapping, or dispatch systems (familiarity with route optimization is a significant plus).

• Experience contributing to operational excellence, including establishing observability metrics, monitoring, and proactive debugging of performance issues.
