Decagon
Senior Software Engineer, Infrastructure
Decagon, San Francisco, California, United States, 94199
About the Role
We're hiring a Senior Infrastructure Engineer to design, build, and operate production infrastructure for high-scale, low-latency systems. You'll own critical services end-to-end, improve reliability and performance, and create paved-paths that let every Decagon engineer ship confidently. 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, set up prototypes, evaluate performance, and scale new features.
Tune service latencies: optimize networking paths, apply smart caching/queuing, and tune CPU/memory/I/O for tight p95/p99s.
Evolve CI/CD, golden paths, and self-service tooling to improve developer velocity and safety.
Support various deployment architectures for customers with robust observability and upgrade paths.
Lead infrastructure-as-code (Terraform) and GitOps practices; reduce drift with reusable modules and policy-as-code.
Participate in on-call and drive down toil through automation and elimination of recurring issues.
Your background looks something like this
6+ 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, and load testing).
Excellent observability chops (OpenTelemetry, Prometheus/Grafana, Datadog) and incident response (PagerDuty, SLO/error budgets).
Clear written communication and the ability to turn ambiguous requirements into simple, reliable designs.
Even better
Experience being an early backend/platform/infrastructure engineer at another company
Strong Kubernetes experience (GKE/EKS/AKS) and experience across multiple cloud providers (GCP, AWS, and Azure)
Experience with customer-managed deployments
Benefits
Medical, dental, and vision
Flexible time off
Daily lunch/dinner & snacks in the office
