Rust Engineer (Part Time)

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

• 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
