About Chamelio

Chamelio is revolutionizing legal tech with an AI-powered Legal Intelligence Platform trusted by some of the world's fastest-growing companies including Wiz, Socure, and Fiverr.

We're solving complex problems at the intersection of AI and legal operations. Join us as we scale our impact globally.

About the Role

• We're looking for a Head of Security to own security end-to-end at Chamelio - from the architecture of our product to the systems our own team runs on.
• We handle some of the most sensitive documents our customers have, and our buyers' security teams scrutinize us accordingly.
• You'll be our first dedicated security hire and the sole internal authority on the subject: setting the standards our engineers build against, owning our compliance posture, and sitting across the table from customer CISOs to defend it.
• This is a hands-on role with real strategic weight - if you want to build a security function from scratch at a company where security is a deal-maker, we want to hear from you.

What You'll Do

• Design, architect, and implement security directly into our product and codebase
• Own our internal security posture: corporate IT, access management, endpoint, and employee security practices
• Lead customer-facing security engagements - pre-sales security reviews, CISO-level discussions, security questionnaires, and enterprise assessments - representing Chamelio's posture to buyers who evaluate us seriously
• Own our compliance program end-to-end, including audits, evidence, and vendor risk
• Set security standards and best practices across R&D and product as the internal authority on the subject
• Build the security review process for how we ship AI features - threat modeling around LLMs, agentic workflows, and customer data boundaries
• Partner with DevOps and engineering on cloud security, secure architecture, and incident readiness
• Grow the security function as we scale, from process to headcount

What You'll Bring

• Passion to own and deliver – you take full responsibility for security outcomes and drive initiatives from idea to production
• Curiosity and adoption of AI tools – you actively use tools like Cursor or Claude Code and are excited about how AI is transforming both software development and the threat landscape
• 7+ years of hands-on security experience, with real depth in product or application security
• Experience in customer-facing security roles, representing a company to client CISOs, IT directors, and security teams across enterprise and SMB
• Strong command of cloud security (AWS/GCP/Azure), web application security, and secure architecture design
• Hands-on experience running or building a compliance program (SOC 2, ISO 27001, or equivalent)
• A builder's mindset - comfortable establishing process and structure where none exists
• Ability to thrive in a fast-paced environment, balancing deep technical execution with high-level strategic and client conversations
• Strong communication skills, effective in a fast-paced startup environment

Bonus Points

• Experience securing LLM-powered applications, agentic systems, or AI infrastructure
• Background working with legal, financial, or other high-stakes documentheavy domains
• Hands-on coding ability in Python or TypeScript
• Experience building a security function from scratch, especially as a founding or first security hire
• Familiarity with Kubernetes, infrastructure-as-code, and cloud-native architectures

Chamelio might be a good fit if you:

• Are relentlessly resourceful: You find creative solutions and don't let obstacles slow you down.
• Have a strong sense of urgency: You have a bias towards doing things today, rather than tomorrow.
• Thrive in startup environments: Fast-paced, high-impact work energizes you (preferred but not required).
• Are excited about the adventure: Building a company from the ground up excites you!
