• Architect APIs, real-time systems, and high-throughput microservices, with a heavy focus on optimizing our core dispatch and logistics engine
• Define testing and review practices, introducing automated frameworks into our release process to improve reliability

• 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
• A proven track record of establishing automated testing frameworks and CI/CD quality gates from scratch, rather than simply participating in an existing testing culture
• Strong systems context awareness, demonstrating the ability to consider downstream effects across adjacent systems to avoid cascading failures
• Experience contributing to operational excellence, including establishing observability metrics, monitoring, and proactive debugging of performance issues
• Strong communication skills with the ability to facilitate discussions, clearly communicate technical trade-offs to non-technical stakeholders, and align teams on technical direction
• Domain expertise in logistics, routing, mapping, or dispatch systems (familiarity with route optimization is a significant plus)
• Curiosity about emerging technologies and experience leveraging AI tools and workflows to improve development velocity
