About us:

 

Talent has no borders. Proxify's mission is to connect top developers around the world with the opportunities they deserve. So, it doesn't matter where you are; we are here to help you fast-track your independent career in the right direction. 🙂

Since our launch, Proxify's developers have successfully worked with 1200+ happy clients to build their products and growth features. 5000+ talented developers trust Proxify and its network to fulfill their dreams and objectives.

Proxify is shaped by a global network of supportive, talented developers interested in remote full-time jobs. Our Glassdoor (4.5/5) and Trustpilot (4.8/5) ratings reflect the trust developers place in us and our commitment to our members' success.

 

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.

 

What we offer:

 

Get paid, not played

No more unreliable clients. Enjoy on-time monthly payments with flexible withdrawal options.

 

Predictable project hours

Enjoy a harmonious work-life balance with consistent 8-hour working days with clients.

 

Flex days, so you can recharge

Enjoy up to 24 flex days off per year without losing pay, for full-time positions found through Proxify.

 

Career-accelerating positions at cutting-edge companies

Discover exclusive long-term remote positions at the world's most exciting companies.

 

Hand-picked opportunities, just for you

Skip the typical recruitment roadblocks and biases with personally matched positions.

 

One seamless process, multiple opportunities

A one-time contracting process for endless opportunities, with no extra assessments.

 

Compensation

Enjoy the same pay, every month with positions landed through Proxify.
