Debug and troubleshoot Rust applications in production environments, including memory safety issues, concurrency bugs, and performance regressions. Contribute to frontend development using React where needed, including integration with micro frontend architectures. Participate in the design and implementation of microservice and distributed system architectures. Write and maintain comprehensive test suites: unit tests, integration tests, and end-toend tests following established best practices. Deploy, monitor, and maintain services in containerized Kubernetes environments. Implement and maintain observability (logging, metrics, tracing) and alerting for missioncritical distributed systems. Mentor junior engineers on Rust best practices, systems design, and production engineering discipline. This 3 month fixed term salaried contract is located in Ontario Canada, preferably in Toronto, with an anticipated hourly range of $75.
