About the Role

Rumble is seeking a Senior Infrastructure Engineer (DDoS) to build, operate, and continuously improve network defenses protecting its global platform from distributed denial-of-service attacks and other high-volume network threats. This role focuses on maintaining the availability, performance, and resilience of mission-critical internet-facing services during adversarial events. You will work across network infrastructure, routing, traffic engineering, CDN, DNS, and security operations to detect, investigate, and mitigate attacks at scale, using network telemetry, flow data, packet analysis, and automation to develop effective protections.

Responsibilities

Design, build, operate, and improve Rumble’s DDoS detection, mitigation, and traffic-scrubbing infrastructure.
Develop resilient network architectures that protect critical services while maintaining availability and performance during high-volume attacks.
Analyze network telemetry, flow data, packet captures, and traffic patterns to identify attacks, distinguish malicious traffic from legitimate demand, and drive mitigation decisions.
Implement and maintain mitigation controls, including filtering, rate limiting, traffic shaping, ACLs, routing controls, blackholing, sinkholing, and traffic diversion.
Partner with CDN, DNS, network, systems, and security teams to improve origin protection, anycast resilience, traffic steering, and incident readiness.
Support capacity planning for attack absorption, mitigation infrastructure, transit connectivity, and operational failover.
Build automation for detection, alerting, configuration changes, mitigation workflows, and incident reporting.
Create and maintain runbooks, attack playbooks, infrastructure documentation, and post-incident reviews.
Participate in an on-call rotation and lead or support response to active security and availability incidents.

Requirements

8+ years of relevant network, security, systems, or infrastructure engineering experience.
Strong understanding of IP networking, TCP/IP, UDP, ICMP, HTTP/HTTPS, TLS, DNS, and internet routing.
Demonstrated hands-on experience with DDoS detection, mitigation, attack response, or protection of high-traffic internet-facing services.
Strong understanding of common DDoS attack vectors, including volumetric, protocol, reflection or amplification, and application-layer attacks.
Experience with BGP, routing policy, traffic engineering, and mitigation techniques such as remote-triggered blackholing, FlowSpec, traffic diversion, filtering, and rate limiting.
Experience interpreting packet captures, network-flow data, traffic telemetry, and service-level metrics during incidents.
Strong Linux systems experience and proficiency with Python, Bash, Perl, or similar languages for automation, monitoring, deployments, and operational response.
Expert troubleshooting skills and the ability to make sound technical decisions under pressure during active incidents.
Excellent technical documentation and verbal and written communication skills, including the ability to communicate incident status to technical and non-technical stakeholders.
