## Job description

[C1.ai](http://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.

## Compensation & benefits

Salary range: $180k – $250k

- Meaningful equity
- Full medical, dental, and vision coverage
- In-office in Portland
- Solid benefits across the board

Due to the nature of this role and its responsibilities supporting our FedRAMP-authorized environment, candidates must be U.S. citizens. This position may involve work that the U.S. Government has determined can only be performed by U.S. citizens on U.S. soil.

Hiring philosophy

We care about both excellence and grit. You don’t need to check every single box to apply—if this feels like the kind of place you want to build, we’d like to hear from you.

[c1.ai](http://c1.ai) is an equal opportunity employer. We consider all qualified applicants without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, disability, or veteran status.

## About C1

## Company Overview

- **Founded**: 2021
- **Founders**: Not publicly available

## Core Business

## Products & Services
- **C1 Platform**: A unified identity and access governance platform that manages access for humans, services, and AI agents. It provides a universal identity graph, real-time activity monitoring, policy-as-code guardrails, and just-in-time access. The platform is designed to be "headless" and exposes all capabilities via API, MCP, CLI, and Terraform, allowing it to be integrated into any tech stack.
- **AI Access Management**: A specific module for governing access for AI agents and tools across data, cloud apps, and infrastructure. It includes self-service MCP access, identity-aware gateways, and support for custom and on-prem MCPs.
- **Intelligent Access Reviews**: AI-driven, risk-based access reviews to automate and streamline compliance.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total Funding of $111M (as of Series B in November 2025)
- **Notable Investors/Partners**: Greycroft (lead, Series B), Accel, Felicis, CrowdStrike, Fuel Capital, Fathom Capital, Active Capital.
- **Growth Signals**: Raised a $79M Series B in November 2025, signaling strong investor confidence and a focus on scaling the platform for the "agentic era." The company is actively hiring across engineering, sales, and operations roles.

## Competitive Advantages
- **First-Mover in AI Identity**: C1 is specifically built for the "agentic era," managing access for AI agents and tools alongside human users, which is a nascent but rapidly growing market.
- **Headless & API-First Architecture**: Unlike traditional IAM tools, C1 is built as a "headless identity infrastructure," exposing all capabilities via API, MCP, CLI, and Terraform. This makes it highly flexible and embeddable for engineering teams.
- **AI-Native Platform**: The platform itself uses AI to drive governance workflows, access reviews, and policy creation, making it faster and more scalable than legacy IAM solutions.
- **Strong Investor Backing**: Backed by top-tier VCs (Accel, Greycroft, Felicis) and a strategic investor in CrowdStrike, providing both capital and credibility.

## Strategic Focus
- **Agentic Identity**: C1 is doubling down on the "agentic era," building the infrastructure to govern access for non-human identities (AI agents, services, API keys) which is a key growth area.
- **Platform Expansion**: Moving beyond traditional IAM to become the "access and context delivery layer" for the entire enterprise, integrating deeply with AI tools and workflows.
- **Go-to-Market**: Scaling sales and channel partnerships (hiring Channel Account Managers) to capture enterprise customers undergoing AI transformation.

## Why Work Here
- **High-Growth Environment**: As a well-funded Series B startup ($111M total), C1 offers the opportunity to work on cutting-edge problems at the intersection of AI and security.
- **Mission-Driven Work**: Employees contribute to building the infrastructure for the "agentic era," a highly relevant and impactful space.
- **Culture & Values**: The company emphasizes empathy, authenticity, and collaboration. It has been recognized by Newsweek as one of "America's Greatest Workplaces 2024" and received a Platinum Bell Seal for workplace mental health.
- **Benefits**: Comprehensive benefits include health coverage, a 401(k) plan with a 35% match up to 10%, 17 days PTO in the first year, paid parental leave, fertility coverage, and flexible work hours.
- **Work Model**: Offers virtual office opportunities and flexible work hours.
- **Engineering Culture**: The platform is built for engineers, with a strong emphasis on API-first, headless architecture, and infrastructure-as-code (Terraform, CLI). This suggests a deep technical culture.
