Senior Principal Site Reliability Engineer

About Us

• Design and build an enterprise-grade chaos engineering platform supporting multi-cluster (K8s + EC2 hybrid), multi-region, and multi-environment (testnet/mainnet) deployments

• Core capability development:

• Fault Injection Engine: Pod-level / Node-level / AZ-level fault simulation, network latency / packet loss / partition, dependency timeout / error injection

• Production Safety Assurance: Blast radius control, one-click Kill Switch, automatic rollback, real-time impact monitoring

• Traffic Isolation: Experiment traffic tagging and isolation to ensure fault injection does not impact real users

• Fault Isolation: Precise impact scoping at service / cluster / AZ granularity

• Design experiment orchestration capabilities supporting complex fault scenario composition (e.g., simultaneous network latency + downstream timeout + cache invalidation)

• Deep integration with existing monitoring, alerting, and SLO systems to achieve an automated closed loop: inject fault → observe impact → determine pass/fail

• Define safety standards and approval workflows for mainnet fault injection

• Design and drive routine chaos experiments:

• Daily patrol-level experiments: Low-risk experiments executed automatically on a daily/weekly basis

• Periodic validation experiments: Monthly/quarterly resilience verification of critical paths

• Large-scale drills: Cross-AZ / cross-region disaster recovery failover validation

• Establish a resilience scoring system to quantify system health based on experiment results

• Deliver improvement recommendations and drive business teams to remediate identified weaknesses

• Evaluate and select the technology foundation (Chaos Mesh / Litmus / custom components — hybrid strategy)

• Develop chaos engineering best practices and playbooks to enable SRE teams and application developers

• Mentor and grow the team (2–3 engineers) in chaos engineering capabilities

• Stay current with industry developments and introduce cutting-edge practices (e.g., AI-driven fault scenario discovery)

• 8+ years of backend / infrastructure engineering experience, with 3+ years dedicated to chaos engineering or stability engineering

• Hands-on experience with large-scale fault injection in production environments (not just test environments), with deep understanding of production safety constraints

• Expert-level proficiency in Kubernetes fault injection (Chaos Mesh / Litmus / custom solutions), familiar with CRD / Operator development

• Proficient in at least one backend language (Go preferred), with platform-level system architecture design capability

• Deep understanding of distributed system failure modes (network partitions, split-brain, cascading failures, data inconsistency, etc.)

• Familiarity with observability tech stack (Prometheus / Grafana / Thanos / OpenTelemetry)

• Excellent technical documentation and solution design skills

• Experience in financial / trading system stability (understanding of transaction consistency and fund safety constraints)

• Experience building SLO / Error Budget frameworks

• Experience building automated fault recovery (self-healing) systems

• Familiarity with AWS infrastructure (EC2 / EKS / Multi-AZ / Multi-Region)

• Knowledge of Netflix Chaos Engineering / AWS Fault Injection Simulator / Gremlin

• Open-source community contributions (Chaos Mesh / Litmus or similar projects)

• Ability to balance "safety" and "validation depth" — not afraid of production injection, while maintaining strict risk control

• Strong cross-team collaboration and influence — chaos engineering requires buy-in from business teams; this role demands persuasion skills

• Self-driven, capable of independently planning and executing in ambiguous situations
