About The Position

CHAOS Industries is hiring a Senior Cloud Infrastructure Engineer to join a small, collaborative team in San Francisco. The team builds the cloud platform supporting advanced radar systems. The role involves designing, building, and operating infrastructure and backend services that transfer mission-critical sensor data from deployed radars to operators. The platform is in production and expanding, and the engineer will scale it as the sensor fleet, customers, and deployments grow.

Requirements

Experience building and operating production infrastructure in at least one major cloud (Azure, AWS, or GCP), defined as code with Terraform, Pulumi, Bicep, or CloudFormation.
Experience running containerized production workloads with Docker on a managed platform such as Azure Container Apps, AWS ECS or Fargate, Google Cloud Run, or Kubernetes.
Strong cloud networking fundamentals, including virtual networks, subnets, routing, DNS, load balancers, private endpoints, and firewalls.
Experience building and operating production backend services in Python, Go, or a similar language, and understanding concurrency, async I/O, connection pooling, and resource limits under load.
Fluency in distributed systems, including consistency and replication, partitioning, caching, back-pressure, idempotency, system failure modes, and graceful degradation.
Experience scaling a production system well beyond its original design and resolving issues that arise during that growth.
Ability to build securely by default, including least-privilege access, keeping secrets out of code, and maintaining patched, hardened systems, and to explain the trade-offs involved.

Nice To Haves

Experience with Azure Government, AWS GovCloud, or other regulated environments such as FedRAMP, CMMC, NIST 800-171, or NIST 800-53.
Experience with real-time and streaming data systems, including WebSockets, server-sent events, pub/sub, and message queues.
Experience with identity and cloud security, including Entra ID, OAuth 2.0/OIDC, managed identities, service-to-service authentication, and policy as code.

Responsibilities

Design and operate Azure infrastructure as code with Terraform, including networking, Azure Container Apps, managed databases, and CI/CD pipelines.
Build and own high-throughput Python (FastAPI) backend services and their data layer, using PostgreSQL/TimescaleDB, Redis, and Cosmos DB to ingest and stream real-time sensor data.
Work with engineering teams across the company to define the architecture of the next generation of the platform.
Own platform security, reliability, and observability, including identity and access, secrets management, network isolation, Datadog monitoring and alerting, and incident response.
