Senior Backend Engineer (Rust / Go & Web3) Experience Required: 8+ years of professional backend development Location: [Remote / Specific Location] Employment Type: Full-time Position Overview We are seeking a highly skilled Backend Technical Expert to lead the construction of a high-performance, ultra-reliable Web3 gaming and betting platform. The core of this project involves high-frequency data processing, seamless on-chain interactions, and complex logic computation. Beyond being a Rust or Go expert, you must possess a rigorous engineering mindset and exceptional remote collaboration skills. Core Requirements 1. Technical Depth (Hard Skills) Programming Languages: 8+ years in backend development. Mastery of either Rust (deep understanding of the ownership model and memory safety) or Go (expert in scheduler mechanisms and high-performance microservice architecture). Web3 Capabilities: Proven experience in Web3 development. Proficient in JSON-RPC interactions, wallet integration, smart contract calls, and on-chain data synchronization (using libraries such as ethers-rs, solana-program, or go-ethereum). Middleware Mastery: Deep understanding of distributed processing with Message Queues (Kafka, Pulsar, or RabbitMQ). Expert in Redis cache design, including data structure optimization, distributed locking, and race condition resolution. Cloud Native: Proficient with Docker containerization and Kubernetes (K8s) environments, with hands-on experience in designing and deploying cloud-native applications. 2. Software Engineering & Quality Exceptional Code Quality: A near-obsessive commitment to code cleanliness and maintainability. You must adhere to Test-Driven Development (TDD) and be accustomed to writing high-quality unit and integration tests to ensure core logic (e.g., RNG, accounting systems) is infallible. Collaboration Standards: Mastery of Git workflows and a strong advocate for the Pull Request (PR) collaboration model. Capable of elevating team standards through detailed Code Reviews and clear technical documentation. Preferred Qualifications (Plus) Domain Expertise: Prior experience in iGaming (online casinos), High-Frequency Trading (HFT), Fintech/Payment systems, or large-scale gaming backends is highly preferred. Security Background: Familiarity with common cryptographic algorithms, Provably Fair protocols, or smart contract auditing. Performance Tuning: A proven track record of handling high-concurrency traffic spikes, resolving system bottlenecks, or troubleshooting memory leaks.
