Senior Software Engineer (Rust) – Remote in the EU

Stack

Responsibilities

• ▹Design and develop control plane microservices, custom Kubernetes operators, and reliable reconciliation engines in Rust and Go
• ▹Author functional and non-functional requirements, architecture specs, system sequence diagrams, and gRPC/Protobuf and REST API schemas
• ▹Develop custom integration modules for network operating systems (SONiC, NVUE, Cumulus) and DPU hardware platforms
• ▹Instrument services end-to-end with OpenTelemetry traces and metrics, performing root-cause analysis across polyglot distributed systems
• ▹Participate in review-gated pull request workflows across Rust, Go, and SQL codebases, ensuring high test coverage through mock-driven testing

Requirements

• ▹5+ years of software engineering experience in cloud-native platforms or systems programming
• ▹Primary mastery of Rust (Tokio async runtime, Tonic, Axum, sqlx) and proficiency in Go as a secondary language
• ▹Strong background in async concurrency models, lock-free patterns, distributed state handling, and mock-driven testing discipline
• ▹gRPC/Protobuf contract design (via tonic/prost) and schema evolution using zero-copy serialization and compile-time type generation
• ▹Experience writing custom Kubernetes controllers/operators using kube-rs with CRD-driven reconciliation patterns
• ▹Commitment to test-driven design, writing highly testable code with mock interfaces for external dependencies
• ▹Proven track record of writing clear architectural specs and engaging in cross-functional design reviews
