Responsibilities

  • Build Scalable APIs: Use Rust’s performance and safety to develop high-performance backend services. Integrate GraphQL to provide a flexible and efficient interface for querying data.
  • Microservices Architecture: Construct microservices with Rust for performance-critical components, leveraging GraphQL to streamline communication between services.
  • End-to-End Applications: Design and develop complete applications where the backend is powered by Rust and communicates with the frontend via GraphQL, ensuring type safety and consistent data flow.
  • Real-time Applications: Create real-time applications like chat apps or live dashboards where Rust handles the high concurrency and GraphQL subscriptions manage real-time data updates.
  • API Gateway Services: Build API gateways in Rust to handle requests to multiple backend services, using GraphQL as an aggregator to offer a unified API to frontend clients.
  • Mutation and Query Handling: Develop advanced query-handling mechanisms, including batching and intelligent caching, leveraging both Rust’s performance benefits and GraphQL’s query capabilities.
  • Library Development: Contribute to or develop open-source libraries in Rust for GraphQL implementations, such as improving existing libraries or creating new tools to make integration easier.
  • Community Projects: Engage with community projects that use Rust and GraphQL to add new features, improve performance, and enhance documentation.

Preferred Qualifications

  • Master’s degree in computer science, computer engineering, computer information systems, software engineering, or related area and 3 years’ experience in software engineering or related area.
  • Background in creating inclusive digital experiences, demonstrating knowledge in implementing Web Content Accessibility Guidelines (WCAG) 2.2 AA standards, assistive technologies, and integrating digital accessibility seamlessly.
