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.
