Senior Site Reliability Engineer
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.
