About the role
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.
