About the Role
We are looking for a Senior Infrastructure Engineer to join Decagon's Infrastructure team. This role involves designing, building, and operating production infrastructure for high-scale, low-latency systems. You will own critical services end-to-end, improve reliability and performance, and create paved paths that enable every Decagon engineer to ship confidently.
Key Responsibilities
- →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 by optimizing networking paths, applying smart caching/queuing, and tuning 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.
Requirements
- ✓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, 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.
