Core Responsibilities **Chaos Engineering Platform Architecture & Development (50%)** - 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 **Production Resilience Validation Framework (30%)** - 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 3. Technology Selection & Team Enablement (20%) - 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) ────── Requirements Must-Have: - 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 Nice-to-Have: - 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) Soft Skills: - 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 **Why Join Us** At Bybit, we are committed to fostering a supportive and enriching work environment. Our benefits include: - Study Growth Fund: We support your professional development and continuous learning. - Internal Events: Participate in regular team-building activities, workshops, and events designed to promote collaboration and innovation. - Global Collaboration: Be part of a diverse, international team, working alongside colleagues from around the world. - Career Advancement: Access opportunities for growth and advancement within a rapidly expanding global company. - Internal Mobility: Grow with us- Your long-term development is important to us. We offer internal job opportunities to help build your career path.
