Senior Cloud Infrastructure Engineer (Azure / Terraform) at Chaos Industries · LumiJobs

Responsibilities

You'll join a small, highly collaborative team in San Francisco building the cloud platform behind some of the world's most advanced radar systems. You'll design, build, and operate both the infrastructure and the backend services that move mission-critical sensor data from radars in the field to the operators who depend on it. The platform is in production and growing fast, and your job is to scale it as our fleet of sensors, customers, and deployments grows.
Cloud Infrastructure - design and operate our Azure infrastructure as code with Terraform: networking, Azure Container Apps, managed databases, and the CI/CD pipelines that deploy to them.
Backend Platform Services - build and own high-throughput Python (FastAPI) services and the data layer behind them (PostgreSQL/TimescaleDB, Redis, Cosmos DB) that ingest and stream real-time sensor data.
Platform Architecture - work with engineering teams across the company to define the architecture of the next generation of the platform.
Operations - own security, reliability, and observability across the platform: identity and access, secrets management, network isolation, monitoring and alerting (Datadog), and incident response.
Minimum Requirements:
Have built and operated production infrastructure in at least one major cloud - Azure, AWS, or GCP - defined in code with Terraform, Pulumi, Bicep, or CloudFormation.
Have run containerized production workloads (Docker) on a managed platform such as Azure Container Apps, AWS ECS or Fargate, Google Cloud Run, or Kubernetes.
Have strong cloud networking fundamentals: virtual networks, subnets, routing, DNS, load balancers, private endpoints, and firewalls.
Have built and operated production backend services in Python, Go, or a similar language, and understand what happens under load - concurrency, async I/O, connection pooling, and resource limits.
Are fluent in distributed systems: consistency and replication, partitioning, caching, back-pressure, idempotency, and how systems fail - and how to design so that they degrade gracefully.
Have scaled a production system well beyond its original design, and fixed what broke on the way.
