Senior Site Reliability Engineer

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 doOwn 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 for5+ 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 haveWeb3 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 useLanguages: Python, plus Rust and Go in the platform.Infrastructure: Kubernetes, AWS, Grafana, Pulumi.Streaming and messaging: NATS.Data stores: PostgreSQL, Redis, S3.Why ChainalysisReal 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 ChainalysisAI is not a feature at Chainalysis - it is a new way of working. One that turns instructions into work done, and helps us move faster than the threats we re built to counter, and we expect our employees to take ownership of the output and ensure quality. As the world s most trusted blockchain analytics platform, Chainalysis sits at a rare intersection of proprietary data, regulatory relationships and crypto expertise that makes it uniquely placed to shape and lead the next era of AI-driven intelligence - and we expect everyone here, regardless of role, to be an active part of it.AI fluency is tied directly to how we measure performance and how we plan to win. There is no substitute for your own curiosity. We provide the tools, workflows, and space to experiment - but the expectation is that you develop these capabilities yourself, bring ideas, and collaborate across teams to reinvent the way work gets done. We are not using AI to do less. We are using it to do what was never possible before.About ChainalysisChainalysis is the blockchain data platform, making it easy to connect the movement of digital assets to real-world services. Powered by deep blockchain data and AI, organizations can investigate illicit activity, manage ri
