- Instrument services with OpenTelemetry traces and metrics and perform root-cause analysis across distributed systems.
- Participate in review-gated pull request workflows across Rust, Go, and SQL codebases while maintaining high test coverage.
- Contribute to open-source systems projects and participate in architecture and cross-functional design reviews.
Requirements
- Bachelor’s or master’s degree in Computer Science, Computer Engineering, or equivalent practical experience.
- At least 5 years of software engineering experience in cloud-native platforms, systems programming, networking, or infrastructure automation.
- Primary mastery of Rust, including Tokio, Tonic, Axum, and sqlx, with strong proficiency in Go.
- Advanced SQL and PostgreSQL knowledge, including gRPC/Protobuf contract design and schema evolution.
- Strong understanding of asynchronous concurrency, lock-free patterns, distributed state handling, and mock-driven testing.
