Backend Rust Developer

✨ WHAT AWAITS YOU HERE: As a Backend Rust Developer, you will help build and evolve backend services connected to Braiins Pool, Hashpower, and our hashpower spot market. The role is not only about writing Rust code. We are looking for an engineer who can understand how backend changes, configuration, pricing logic, data flows, and operational behavior can influence the market as a whole. You will work primarily with Rust/Tokio microservices using gRPC/Protocol Buffers, Kafka, PostgreSQL/SQLx, Consul, Vault, Docker, Kubernetes, and GitLab CI/CD. Because the product touches market behavior, availability, user incentives, and data-driven decisions, strong seniority, analytical thinking, and ideally experience with mathematical statistics are more important than narrow specialization in one programming language. Depending on your strengths, you may also touch TypeScript/React frontend code, Python-based tools or legacy services, internal automation, deployment workflows, and AI-assisted development processes. 🤝 KEY RESPONSIBILITIES: - Design, build, maintain, and improve backend services for Braiins Pool, Hashpower, and related market-oriented products. - Reason about how service behavior, configuration changes, pricing or allocation logic, data quality, latency, and reliability can affect users and market dynamics. - Work with Rust/Tokio microservices, gRPC/Protocol Buffers, Kafka, PostgreSQL/SQLx, Consul, Vault, Docker, Kubernetes, and GitLab CI/CD. - Contribute to API design, service communication, data flows, database changes, testing, observability, and production readiness. - Collaborate with product, analytics, frontend, QA, support, SRE, and platform teams to deliver reliable product changes with clearly understood impact. - Use data, logs, metrics, experiments, and statistical reasoning to validate assumptions and assess the effect of changes. - Improve internal Rust libraries, service patterns, development workflows, and shared engineering practices. - Help m
