Join OCI to design and deliver cloud-scale DDoS protection as part of our edge security platform. You’ll design and ship high-performance detection and mitigation systems, automate operations end-to-end, and help define the technical foundation for customer-facing DDoS capabilities. Basic qualifications • 6+ years building production backend systems (at least 3 years in high-scale or low-latency environments)., • Proficiency in one or more: Java/Python/C++/Rust/Go, • Strong preference for Java for control-plane/services., • Strong systems design skills: concurrency, memory management, performance tuning, API design, and distributed systems fundamentals., • Experience with DevOps at scale: CI/CD, automated testing, canarying, rollout/rollback, and configuration management., • IaC expertise (e.g., Terraform) and solid cloud infrastructure fundamentals., • Familiarity with DDoS or network security services and related attack/defense patterns., • Solid networking knowledge: TCP/IP, IPv4/IPv6, BGP fundamentals; DNS/DHCP understanding., • Observability experience (metrics, tracing, alerting) and operational excellence mindset. Preferred qualifications • Experience with anycast routing, traffic steering, and multi-region service readiness., • Exposure to SDN, programmable data planes, or hardware mitigation platforms., • Advanced telemetry/streaming pipelines for near-real-time detection (e.g., high-rate packet/flow analytics)., • Background in resilience engineering, chaos testing, and capacity planning at hyperscale., • Containerization/orchestration experience and secure service-to-service communication (mTLS, policy)., • Familiarity with zero trust principles, segmentation, and modern security architectures. How you’ll have impact • Ship core DDoS detection/mitigation capabilities that protect OCI’s Tier 0 availability., • Enable new customer-facing DDoS offerings with self-service policy and visibility., • Raise engineering quality, automation, and compliance maturity across the stack. Ways of working • Security and privacy by design; auditable controls and policy adherence from day one., • Data-driven delivery with clear KPIs, SLOs, and stage gates from prototype to GA., • Collaborative, inclusive engineering culture with code reviews, design docs, and knowledge sharing. What you’ll do • Design and build low-latency backend services for DDoS detection, classification, and mitigation across OCI’s global edge., • Implement scalable data and control planes (policy, signaling, telemetry, orchestration) with strong fault isolation and resiliency., • Develop traffic engineering capabilities (anycast, BGP signaling, routing policy) and integrate with OCI networking, DNS, and edge services., • Own operational readiness: SLOs/SLAs, on-call health, incident response, runbooks, and post-incident improvements., • Build automation-first workflows: CI/CD pipelines, test frameworks, canary/blue-green releases, and infrastructure-as-code., • Create robust observability (metrics, logs, traces) and capacity/scale modeling for high-throughput, high-availability systems., • Partner with product, SRE, and network engineering to deliver roadmap features from concept to GA with security-by-design., • Contribute to threat modeling, architecture reviews, and compliance/audit readiness for Tier 0 services.
