• Design software using idiomatic Rust and established engineering best practices.
• Develop concurrent and parallel applications using appropriate Rust concurrency models.
• Implement asynchronous applications using async Rust, futures, tasks, and appropriate runtimes.
• Design and develop scalable backend services, APIs, and distributed components.
• Build RESTful APIs, gRPC services, and other service interfaces where appropriate.
• Develop event-driven services and asynchronous processing systems.
• Integrate applications with message brokers, queues, streaming platforms, and external services.
• Develop systems that interact with databases, caches, storage platforms, and distributed data systems.
• Design efficient data structures, algorithms, and processing pipelines.
• Optimize CPU utilization, memory consumption, latency, throughput, and I/O performance.
• Conduct profiling, benchmarking, load testing, and performance analysis.
• Identify bottlenecks and implement targeted performance improvements.
• Develop efficient memory-management and resource-management strategies.
• Ensure applications handle errors, failures, timeouts, retries, and resource exhaustion appropriately.
• Design systems with fault tolerance, graceful degradation, and recovery mechanisms.
• Develop secure authentication and authorization mechanisms.
• Implement appropriate encryption, secrets management, input validation, and access controls.
• Apply secure coding principles and protect applications against common security vulnerabilities.
• Collaborate with cybersecurity teams to identify and remediate software-security risks.
• Develop unit, integration, functional, system, and end-to-end tests.
• Establish effective testing strategies for complex and performance-sensitive systems.
• Improve automated test coverage and software quality.
• Conduct code reviews and provide detailed technical feedback.
• Maintain high standards for code quality, readability, maintainability, and reliability.
• Investigate production incidents, software defects, crashes, memory issues, and performance problems.
• Perform root-cause analysis and implement permanent corrective actions.
• Analyze logs, traces, metrics, stack traces, core dumps, and diagnostic information.
• Develop observability capabilities covering metrics, structured logging, tracing, health checks, and system diagnostics.
• Work with DevOps and platform teams to improve deployment and operational reliability.
• Develop and maintain CI/CD pipelines for Rust applications.
• Build and maintain containerized Rust applications using Docker and Kubernetes where appropriate.
• Develop software for cloud and distributed infrastructure environments.
• Integrate Rust applications with cloud services, storage systems, networking services, and managed platforms.
• Support infrastructure-as-code and automated deployment practices where relevant.
• Design applications for high availability, resilience, disaster recovery, and business continuity.

• Design software capable of operating efficiently under high workloads and constrained resources.
• Develop reusable Rust crates, libraries, SDKs, frameworks, and internal engineering components.
• Establish reusable coding patterns and technical standards for Rust development.
• Evaluate third-party Rust crates for security, stability, maintainability, licensing, and performance.
• Manage dependencies and address dependency vulnerabilities and compatibility issues.
• Maintain Cargo configurations, workspace structures, build processes, and dependency management.
• Configure and maintain appropriate Rust compiler, toolchain, linting, formatting, and build standards.
• Use tools such as Cargo, rustfmt, Clippy, testing frameworks, profilers, and debugging utilities effectively.
• Design and implement integrations with internal platforms and external systems.
• Maintain clear API contracts, schemas, interfaces, and compatibility requirements.
• Participate in migration of legacy components to Rust where technical and business value justify modernization.
• Assess existing systems and identify opportunities for performance, reliability, security, or maintainability improvements.
• Collaborate with Product Managers, Architects, QA Engineers, DevOps Engineers, Security Engineers, Data Engineers, and other stakeholders.
• Participate in Agile planning, technical refinement, estimation, reviews, and retrospectives.
• Break complex technical requirements into manageable engineering tasks.
• Estimate technical effort, identify dependencies, and communicate delivery risks.
• Lead technical discovery, prototypes, proofs of concept, and architectural experiments.
• Evaluate emerging Rust libraries, frameworks, runtimes, tooling, and systems-programming techniques.
