Senior Manager, DDOS Engineering and Development in Sheffield

Join the OCI DDOS Team as we embark on operating our DDOS Infrastructure Platform while we develop a DDOS Product for our customers. Manage a team that designs, develops, troubleshoots and debugs software programs for databases, applications, tools, networks etc.

Oracle Cloud Infrastructure (OCI) is seeking a Senior Manager to lead the engineering team building and operating OCI’s cloud-scale DDoS protection platform and customer-facing DDoS product. You will collaborate on strategy, roadmap, and delivery for globally distributed detection and mitigation systems, while developing a high-performing team and driving operational excellence.

What you’ll own

• Define multi-quarter roadmap and quarterly plans for DDoS platform and product, aligned to OCI priorities and revenue goals.
• Make data-driven tradeoffs across feature velocity, resiliency, and cost; manage build-vs-buy with clear ROI.
• Lead new service development from concept and business case through GA: PRDs, architecture, stage gates, resourcing, and launch readiness.
• Deliver low-latency, high-availability backend services for detection, classification, and mitigation across OCI’s global edge.
• Drive scalable data and control planes (policy, signaling, telemetry, orchestration) with strong fault isolation and resiliency.
• Guide anycast routing, BGP signaling, and traffic steering; integrate with OCI Networking, DNS, and edge services.
• Oversee capacity modeling, scale testing, and multi-region readiness.
• Establish and meet SLOs/SLAs and KPIs; ensure on-call health, incident readiness/response, and rigorous post-incident improvements.
• Champion automation-first operations: CI/CD, test frameworks, canary/blue-green releases, and infrastructure-as-code.
• Build robust observability (metrics, logs, traces) and near-real-time telemetry/streaming pipelines for detection at scale.

Security, compliance, and risk

• Govern threat modeling, architecture reviews, and risk remediation; ensure auditability and policy adherence for Tier 0 services.
• Embed security and privacy by design; enforce zero trust principles and secure service-to-service communication (mTLS, policy).
• Hire, onboard, and grow a diverse, high-performing team; set clear OKRs, provide ongoing coaching and feedback, and drive career paths and succession planning.
• Mentor senior ICs and emerging leaders; establish technical ladders, design reviews, and knowledge-sharing rituals.

Cross-functional leadership and communications

• Partner closely with Product, SRE, Networking, Architecture, and Security to land integrated capabilities and resilient outcomes.
• Provide crisp executive updates on status, risks, mitigations, and outcomes.

Basic qualifications

• 10+ years in network/security or backend engineering, including 4+ years leading engineering teams delivering production-critical services at scale.
• Proven delivery of large-scale DDoS or network security programs in cloud, hyperscale, or ISP environments.
• Strong systems and distributed design skills: concurrency, performance, resiliency, API design, and fault isolation.
• Deep networking fundamentals: TCP/IP, IPv4/IPv6, BGP; DNS/DHCP understanding; ability to guide architectural decisions.
• Hands-on fluency with automation-first operations and DevOps at scale: CI/CD, automated testing, rollout/rollback, config management, and IaC (e.g., Terraform).
• Proficiency with one or more: Java, Go, Python, C++, or Rust; strong preference for Java for control-plane/services.
• Demonstrated leadership in incident management, resilience engineering, observability, and operational maturity.
• Excellent stakeholder management and executive communication; data-driven prioritization and tradeoff decision-making.

Preferred qualifications

• Experience with anycast routing, traffic steering, multi-region service readiness, and capacity/scalability modeling.
• Exposure to SDN, programmable data planes, or hardware mitigation platforms.
• Advanced telemetry/streaming for near-real-time detection (e.g., high-rate packet/flow analytics).
• Containerization/orchestration and secure service-to-service communication (mTLS, policy).
• Familiarity with zero trust, segmentation, and modern security architectures.
• Track record building inclusive teams; coaching frameworks; performance management best practices.

How you’ll have impact

• Protect OCI’s infrastructure availability with resilient, automated DDoS detection and mitigation at hyperscale.
• Launch and evolve customer-facing DDoS offerings that provide self-service policy, visibility, and strong SLAs.
• Raise engineering quality, automation coverage, and compliance maturity across the stack.
• Build and scale a world-class engineering organization grounded in security-by-design and operational excellence.

Ways of working

• Security and privacy by design with auditable controls; policy adherence from day one.
• Data-driven delivery with clear KPIs, SLOs, and stage gates from prototype to GA.
• Collaborative, inclusive engineering culture with design docs, code reviews, and continuous learning.
