Cloud Infrastructure Platform Engineer

📋 Description

• • Architect and run Kubernetes-based platforms that span multiple clusters and regions, ensuring 99.9%+ availability for real-time multimodal AI experiences that power thousands of concurrent Superhuman conversations.
• • Design paved-path abstractions—Terraform/Pulumi modules, golden container images, service templates—that let product teams ship new capabilities in hours instead of weeks while enforcing security, cost, and compliance policies automatically.
• • Own end-to-end CI/CD: build GitOps-driven pipelines, progressive deployment strategies (blue-green, canary, feature flags), and runtime orchestration that safely roll out updates to services handling high-throughput voice, video, and text traffic.
• • Evolve global networking and traffic management: configure ingress controllers, service mesh (Istio/Linkerd), edge CDNs, load-balancers, and DNS to deliver sub-100 ms latencies for interactive demos and live sales calls anywhere on Earth.
• • Implement defense-in-depth security: zero-trust identity, short-lived tokens, secrets management (Vault, KMS), network policies, OPA-based admission control, and auditable policy-as-code that satisfy SOC 2, ISO 27001, and enterprise procurement questionnaires.
• • Instrument everything for observability: deploy Prometheus, Grafana, OpenTelemetry, and continuous profiling; define SLOs/SLIs for latency, error rate, and cost per conversation; lead blameless postmortems that turn incidents into durable platform improvements.
• • Plan and execute 10× capacity growth: choose optimal instance types, design autoscaling policies, tune workload placement, introduce caching layers (Redis, CDN), and select storage (block, object, vector DB) to keep marginal cost per conversation trending downward.
• • Collaborate daily with ML/IR engineers to optimize GPU scheduling, retrieval-augmented generation workflows, memory stores, and tool-call runtimes so that Superhumans answer complex product questions in <2 seconds.
• • Partner with product and backend teams to embed reliability and cost awareness into every feature launch; run architecture reviews and game-day drills that surface risks before customers feel them.
• • Contribute to an inclusive, feedback-rich culture: host internal tech talks, mentor junior engineers, and champion diverse perspectives that make our platform—and our company—stronger.
• • Participate in a fair, well-compensated on-call rotation (roughly one week in six) armed with automated runbooks, paging policies that respect sleep, and a blameless incident culture focused on learning and resilience.
