Site Reliability Engineer

C1.ai is building a horizontal identity platform

Identity is becoming the control plane for modern companies. Every organization runs on dozens—sometimes hundreds—of systems that need to answer the same basic question: who can do what, when, and why?

The old approach doesn’t hold up. It’s either IT teams duct-taping systems together, or rigid IGA tools that only work across a narrow set of HR and SSO integrations. That’s not going to cut it for the next decade.

We’re building something more foundational: a horizontal identity platform that any company—and increasingly, any AI agent—can plug into to understand and manage access. SaaS apps, infrastructure, internal tools, AI agents—if it has a concept of “who,” it should connect to us.

We’re still small, and we move fast. If you want to help build this from the ground up, you’ll have real ownership here.

What You'll Do

• Own the reliability and scalability of our platform
• —design, build, and operate the infrastructure that keeps C1 running for customers who depend on us. You'll work on both our core cloud environment, as well as our FedRAMP environment.
• Build observability that drives action
• —create monitoring, alerting, and tooling that helps teams understand system behavior and respond to incidents quickly
• Drive operational excellence across engineering
• —partner with product teams to ensure new features are built with reliability in mind from the start
• Automate relentlessly
• —if you're doing something twice, build a system to do it for you. We believe in infrastructure as code and eliminating toil.
• Respond to and learn from incidents
• —lead incident response, conduct blameless postmortems, and drive systemic improvements
• Plan and execute infrastructure projects with incremental deliverables—you'll assess technical risks, communicate tradeoffs, and ship iteratively

What We're Looking For

• You Likely Have
• A track record of building and operating production systems at scale—you've kept real systems running for real customers
• Deep experience with cloud infrastructure (AWS, GCP, or similar) and infrastructure-as-code (Terraform, Pulumi, or similar)
• Strong programming skills in Go, Python, or similar—you write tools and automation, not just scripts
• Experience with Kubernetes and container orchestration in production
• Strong systems thinking—you understand how components interact and where failures cascade
• High agency—you figure out what needs to be built, not just how to build what you're told. You move fast and unblock yourself.
• Deep understanding of observability—you know how to instrument systems, build dashboards, and create alerts that actually matter
• Experience with AI-assisted development (Claude Code, Cursor, Copilot, or similar)—you're already using these tools and excited about what's next
• Clear, persuasive communication—you can explain complex systems to diverse audiences and drive alignment during incidents
• Ego in check—you care about getting it right, not being right
• You Might Also Have
• Experience with AI/ML infrastructure or serving LLMs in production
• Background in security-focused environments or compliance frameworks (SOC 2, FedRAMP, etc.)
• Experience building developer platforms or internal tooling
• Familiarity with identity systems and protocols (SCIM, SAML, OAuth, LDAP)
• Contributions to open source projects or engineering communities
• How we work
• Impact matters more than ownership.
• We’d rather ship something real than talk about it.
• People here are trusted to operate independently.
• If something isn’t working, we fix it properly—we don’t paper over it.
• Using AI effectively is expected, not optional.
