Senior Cloud Infrastructure Engineer (Azure / Terraform) — San Francisco, CA

San Francisco, CA (On-site) | $140k–$240k base + pre-IPO stock options

Build and scale the cloud platform behind some of the world’s most advanced radar systems.

h4ufJ RbURxeDkwC is a defense tech company founded in 2022 that has raised $1B from investors including 8VC, Accel and Valor Equity Partners. You’ll design, build and operate the infrastructure and backend services that move mission-critical sensor data from radars in the field to the operators who depend on it.

What you’ll do

• Design and run Azure infrastructure as code with Terraform: networking, Azure Container Apps, managed databases and CI/CD pipelines

• Build and own high-throughput Python (FastAPI) services and the data layer behind them (PostgreSQL/TimescaleDB, Redis, Cosmos DB) for real-time sensor data

• Own security, reliability and observability: identity and access, secrets, network isolation, monitoring and alerting (Datadog), incident response

• Scale a platform already in production as sensors, customers and deployments grow

• Define the architecture of the next-generation platform with engineering teams across the company

You’re a fit if you have

• Built and operated production infrastructure in a major cloud (Azure, AWS or GCP), defined in code with Terraform, Pulumi, Bicep or CloudFormation

• Run containerized production workloads (Docker) on a managed platform such as Azure Container Apps, ECS/Fargate, Cloud Run or Kubernetes

• Strong cloud networking fundamentals: virtual networks, subnets, routing, DNS, load balancers, private endpoints, firewalls

• Built and operated production backend services in Python, Go or similar, and understand what happens under load: concurrency, async I/O, connection pooling, resource limits

• Fluency in distributed systems (consistency, replication, partitioning, caching, back-pressure, idempotency, graceful degradation), and have scaled a production system well beyond its original design and fixed what broke

• A secure-by-default approach: least-privilege access, secrets kept out of code, hardened and patched systems

Nice to have

• Azure Government, AWS GovCloud or other regulated environments (FedRAMP, CMMC, NIST 800-171 or 800-53)

• Real-time and streaming data systems: WebSockets, server-sent events, pub/sub, message queues

• Identity and cloud security: Entra ID, OAuth 2.0 / OIDC, managed identities, service-to-service authentication, policy as code

What you get

• Medical, dental and vision, 100% paid by the company

• 401k with 50% company match up to 6% of pay, plus FSA, HSA and life insurance

• Pre-IPO stock options, relocation assistance, and annual bonuses (coming soon)

• Unlimited PTO and a casual dress code

• Free daily lunch while you’re working on-site, plus a fully stocked kitchen
