About the job
ABOUT FORMAL
Formal is building a network security platform for the AI era. As agents gain access to sensitive data and production systems, organizations need control over the actions they take and the data they receive. We enforce those controls directly in the network path, with a shared policy layer for humans and agents across databases, infrastructure, APIs, and AI tools.
We are trusted by leading companies such as Cursor http://cursor.com, Decagon https://decagon.ai, Notion http://Notion.com, and more to solve problems across data security and compliance, data quality management, and infrastructure access.
Formal is backed by top-tiers VCs including Thrive Capital and Y Combinator with angel investors that include executives and founders from Datadog, Clickhouse, Plaid, and Vanta.
ABOUT THE ROLE

You'll help own and make the platform easier to deploy, operate, and upgrade in our cloud and customer environments.

- Scale log ingestion and search; improve throughput, indexing lag, API latency, and storage costs.
- Build repeatable on-prem installations and upgrades, including configuration, data migrations, and rollback.
- Establish useful alerts and reliability targets; lead incident response and eliminate recurring failures.
- Automate provisioning with Terraform and Helm; improve CI/CD, capacity planning, backups, and recovery.
WHAT YOU NEED
- Experience building and operating production cloud infrastructure on AWS or Google Cloud using Terraform.
- Experience operating production Kubernetes clusters, including deployments, ingress, autoscaling, and upgrades.
- Strong Linux and networking fundamentals, including DNS, TLS, and load balancing.

- Experience with CI/CD, observability, and operating data pipelines or distributed APIs in production.
- A track record of automating operational work and owning services through incidents and upgrades.
NICE-TO-HAVES
- Experience deploying and supporting on-prem software across customer networks and infrastructure.
- Experience with search systems, Kafka, PostgreSQL, or Temporal.
- Experience with Helm, Bazel, self-hosted CI runners, or environments for AI coding agents.
