The Role: We are looking for a Senior Backend Rust Developer to join one of our high-growth client teams as a technical lead for their core systems. In an era where performance and memory safety are non-negotiable, you will be responsible for architecting and building low-latency, high-throughput services that serve as the backbone of the client's platform. You will lead the transition from legacy services to high-performance Rust microservices, leveraging the ownership model to eliminate data races and ensure memory safety. This is a role for a developer who loves "getting close to the metal" while maintaining the productivity of a modern web stack. What we are looking for:
- Professional experience building production-grade applications in Rust. You should have a deep understanding of ownership, borrowing, lifetimes, and the Send/Sync traits.
- Strong experience with the Tokio ecosystem and asynchronous programming patterns.
- Proficiency with modern Rust web frameworks such as Axum, Actix-web, or Rocket.
- Proven ability to design distributed systems using gRPC, Protocol Buffers, and message brokers like Kafka or RabbitMQ.
- Advanced knowledge of SQL (PostgreSQL preferred) and experience with asynchronous ORMs or query builders like sqlx or Diesel.
- Hands-on experience with containerization (Docker/K8s) and deploying Rust services to cloud environments (AWS/Azure/GCP).
- Experience with profiling tools (e.g., flamegraph, valgrind) to identify and resolve bottlenecks in high-load scenarios.
- Strong verbal and written English; comfortable leading technical discussions with cross-functional stakeholders.
- Time zone: CET (+/
- 3 hours). We are unable to consider applications from candidates in other time zones. Nice-to-Have:
- Experience with WebAssembly (Wasm) for edge computing or browser-based logic.
- Knowledge of Infrastructure as Code (Terraform/Pulumi).
- Familiarity with "Unsafe Rust" and when (and when not) to use it.
- Background in low-level systems languages like C or C++.

Responsibilities:

- Design and implement highly performant backend services that are robust, maintainable, and type-safe.
- Lead the shift toward memory-safe distributed systems, ensuring zero-cost abstractions are utilized effectively.
- Conduct rigorous code reviews, emphasizing idiomatic Rust ("Rustacean" style) and safety best practices.
- Architect secure and scalable RESTful and gRPC APIs for consumption by frontend and mobile applications.
- Maintain high code quality through comprehensive unit, integration, and property-based testing.
