About the Team
The Infrastructure team builds and operates foundations powering Decagon: networking, data, ML serving, developer platform, and real-time voice. Focus areas include Core Infra (networking, compute, storage, security, IaC), Data Infra (streaming/batch platforms), ML Infra (GPU/model serving), Platform (CI/CD, core services), and Voice Infra (telephony/WebRTC).
About the Role
Senior Infrastructure Engineer designing, building, and operating production infrastructure for high-scale, low-latency systems. Own critical services end-to-end, improve reliability/performance, and create paved-paths for confident shipping.
In this role, you will
- Design and implement critical infrastructure services with strong SLOs, clear runbooks, and actionable telemetry.
- Partner with research and product teams to architect solutions, prototype, evaluate performance, and scale features.
- Tune service latencies: optimize networking, caching/queuing, CPU/memory/I/O for tight p95/p99s.
- Evolve CI/CD, golden paths, and self-service tooling for developer velocity and safety.
- Support deployment architectures with observability and upgrade paths.
- Lead infrastructure-as-code (Terraform) and GitOps; reduce drift with reusable modules and policy-as-code.
- Participate in on-call and drive down toil through automation.
Your background looks something like this
- 5+ years building and operating production infrastructure at scale.
- Depth in at least one area across Core/Data/AI-ML/Platform/Voice, with curiosity to learn the rest.
- Proven track record meeting high availability and low latency targets (owning SLOs, p95/p99, load testing).
- Excellent observability (OpenTelemetry, Prometheus/Grafana, Datadog) and incident response (PagerDuty, SLO/error budgets).
- Clear written communication and ability to turn ambiguous requirements into simple, reliable designs.
Even better if you have
- Experience as early backend/platform/infrastructure engineer.
- Strong Kubernetes (GKE/EKS/AKS) and multi-cloud (GCP, AWS, Azure).
- Experience with customer-managed deployments.
