Continuously improve observability using Datadog and related tooling to monitor performance and proactively prevent outages. Drive architectural decisions that strengthen system reliability, security, and scalability in AWS. What we're looking for: 8+ years of experience in site reliability engineering or similar roles. Deep expertise in AWS networking (VPC design, Transit Gateway, PrivateLink, routing, security groups, NACLs). Strong experience with Nginx (configuration, tuning, scaling, troubleshooting). Strong expertise in Kubernetes (K8s) and Amazon EKS. Advanced skills in AWS infrastructure setup, management, and optimization. Proficiency in infrastructure as code (Terraform, Terraform Cloud). Strong programming skills in Python and/or Go. Experience with system monitoring (Datadog) and logging/archiving practices. Extensive experience with GitHub Actions for CI/CD pipelines. Proven track record with containerized microservice architectures (Docker). Experience with Kafka. Experience working in PCI or other regulated environments. Gold Stars: Advanced network security design — experience with segmentation strategies, zero-trust architectures, and firewall policy management. Performance optimization expertise — analyzing latency and throughput, tuning DNS resolution, load balancing, and packet-level troubleshooting. Observability leadership — hands-on with Datadog dashboards, metrics strategy, log pipelines, and tracing at scale. Resiliency and chaos engineering — designing fault-tolerant architectures and running game days to validate recovery plans. Compliance and governance experience — prior work in regulated industries (e.g., PCI, SOC 2, HIPAA) beyond just technical enforcement. Cross-team leadership — ability to influence architecture decisions across product and platform teams, and mentor engineers on reliability and networking best practices. Startup and scale-up experience — familiarity with rapid growth environments where infrastructure must evolve quickly while staying reliable. #LI-REMOTE Our Commitment to Diversity, Equity, and Inclusion We proudly celebrate the unique qualities that make you you, 365 days a year, and not just because it’s the right thing to do or good for business.
