About the Role Remotebase places senior engineers with fast-growing product companies around the world. We’re building a pool of experienced Rust Developers for Part-time Engagements with our clients. You’ll build and maintain high-performance, reliable backend and systems software. Projects range from backend services and APIs to infrastructure tooling, data pipelines and performance-critical components. This role suits engineers who already write production Rust and want flexible, meaningful work alongside their other commitments. What You’ll Do • Design, build and maintain production-grade services and libraries in Rust • Write safe, idiomatic and well-tested code, with careful attention to performance and memory use • Build async services with Tokio and frameworks such as Axum, Actix-web or Tonic (gRPC) • Profile and optimize hot paths, and find and fix concurrency, latency and memory issues • Integrate with databases, message queues and cloud infrastructure • Review code, guide less-experienced engineers and contribute to technical design decisions • Work asynchronously with distributed teams, with clear written communication Requirements • 5+ years of professional software engineering experience, including 3+ years of production Rust • A deep understanding of ownership, borrowing, lifetimes, traits and generics • Strong hands-on experience with async Rust (Tokio, futures, Send/Sync bounds) • Experience building and running backend services or systems software in production • Solid grasp of concurrency, memory management and performance profiling • Comfortable with testing in Rust (unit, integration, property-based) and with CI/CD • Experience with SQL or NoSQL databases (Postgres, Redis and so on) through crates such as sqlx, Diesel or SeaORM • Familiarity with Docker, Linux and at least one cloud provider (AWS, GCP or Azure) • Strong written and spoken English • Reliable availability of 20 hours/week, with 4 hours of overlap with US timezone. Nice to Have • Unsafe Rust, FFI (C/C++ or Python via PyO3) or WebAssembly • Embedded, networking, blockchain or distributed-systems experience • Open-source contributions to the Rust ecosystem • Experience with observability tools (tracing, OpenTelemetry, Prometheus) • Background in C++ or Go Benefits In addition to a market competitive compensation, we have a reward philosophy that expand beyond this. • Fully remote with office optional.
