Senior Site Reliability Engineer

职位要求 / 描述

The engineering team at Chainalysis is inspired by solving the hardest technical challenges and building products that establish trust in cryptocurrencies. We are looking for a strong Site Reliability Engineer to join our Hexagate team in Tel Aviv. The Hexagate team builds cybersecurity products that protect on-chain and web3 assets. We sit at the intersection of cybersecurity and blockchains—an adversarial space where attacks are constant and response time matters. We’re building a real-time on-chain detection and response platform that combines ML-driven threat intelligence, custom detections, and an LLM-powered rules engine to protect on-chain assets. What you’ll do - Own reliability as a product capability: define and evolve SLOs, alerting standards, incident response practices, and production readiness expectations across the platform. - Build and improve the platform foundations that help engineering teams ship safely and quickly, including CI/CD, deployment workflows, and infrastructure automation. - Design and operate resilient, observable systems that support our real-time ingestion, detection, and response workloads. - Lead improvements in scalability, performance, and operational maturity across services and environments. - Drive modernization of our infrastructure stack, including Kubernetes-based workloads, infrastructure as code, and standardized operational patterns. - Improve developer experience by creating internal tooling, paved roads, and clear operational standards so engineers can own services from development through production. - Partner closely with backend and platform engineers to reduce toil, prevent recurring classes of failure, and raise the reliability bar across the organization. - Take part in incident management, root cause analysis, and follow-through on systemic fixes—not just short-term mitigation. WHAT WE’RE LOOKING FOR - 5+ years of experience in SRE, infrastructure engineering, platform engineering, or a closely related role with strong hands-on production ownership. - Strong experience building and operating cloud-native systems in production, ideally in high-growth SaaS, fintech, cybersecurity, or similarly demanding environments. - Deep practical experience with Kubernetes, AWS, and infrastructure as code tools such as Terraform or Pulumi. - Strong understanding of observability, monitoring, debugging, and performance tuning for distributed systems. - Experience building or maintaining CI/CD systems, deployment tooling, and operational automation. - Solid coding ability in Python, Go, or Rust, with the ability to build internal tools and automate operational workflows. - Sound judgment around reliability trade-offs, failure modes, and safe delivery practices. - A collaborative mindset: you enjoy enabling product teams, mentoring engineers on operational best practices, and building a culture of shared ownership rather than acting as a ticket-based support function. - High ownership and a bias toward durable solutions that make systems more stable, secure, and scalable over time. NICE TO HAVE - Web3 or blockchain experience, or strong interest in the space. - Experience with real-time or streaming systems. - Background in security, fraud, risk, or other adversarial domains. - Experience building internal developer platforms or defining reliability standards used across multiple teams. TECHNOLOGIES WE USE - Languages: Python, plus Rust and Go in the platform. - Infrastructure: Kubernetes, AWS, Grafana, Pulumi. - Streaming and messaging: NATS. - Data stores: PostgreSQL, Redis, S3. WHY CHAINALYSIS - Real problems. Real attackers. Real impact. - Small team, high ownership, close to customers. - Best of both worlds: startup pace with the backing and data advantage of the world’s leading blockchain intelligence company. AI at Chainalysis AI is not a feature at Chainalysis - it is a new way of working. One tha
