Head of Information Security

The Company

Sendbird is the #1 CPaaS platform for in-app communications — an enterprise-grade infrastructure company that gives businesses the APIs and SDKs to embed real-time chat, voice, and video directly into their own products. Over 4,000 brands trust us. Seven billion messages flow through our platform every month. 300 million monthly active users.

We powered conversations for DoorDash, Match Group, Noom, Yahoo Sports, Rakuten, and thousands more. We were good at what we did. Really good.

So we asked what comes next. With decades of leadership in communications infrastructure, the answer was clear: AI. In February 2025, we launched our AI agent for enterprise CX. Later that year, we introduced Delight.ai — and the name says everything about what we believe. AI's real promise isn't efficiency. It isn't cost savings. It's restoring what customer experience lost somewhere along the way: the feeling of being understood, of being genuinely cared for. We don't want customers to feel satisfied. We want them to feel delighted.

The Product

Delight.ai is the AI concierge for customer experience. Most AI agents forget you the moment the conversation ends. Ours doesn’t. Delight.ai builds memory over time, learns preferences, and connects context across every channel—chat, SMS, email, voice, WhatsApp—without losing the thread. We’re building AI that makes customers feel understood, seen, and remembered.

Why Head of IT & Security

Security at most companies is reactive. A checkbox for auditors. A speed bump for engineers. A department that says no.

That’s not what we’re building.

We’re an AI company handling enterprise-grade conversations at global scale, and our customers trust us with data that matters. That trust isn’t a nice-to-have. It’s a competitive differentiator. It’s why DoorDash and Match Group chose us. It’s why we’ve earned certifications that our competitors are still chasing.

Security here means being a partner to the business, not a blocker. It means building systems that scale as fast as we do. It means someone who understands that being a 24/7 global platform demands proactive security thinking—not just incident response. And it means someone who recognizes that AI doesn’t just change our product—it changes the threat surface too.

We’re not looking for someone who manages security from a distance. We’re looking for a practitioner who rolls up their sleeves, builds programs that work well, and earns trust across the engineering org by being someone people want to work with.

The Role

This reports to the CFO. You'll lead a high-functioning, mature, and global team located in the United States and South Korea, with end-to-end accountability for Security, IT, and Compliance, ensuring these functions work in harmony to support our global scale.

You'll inherit a world-class program that's already SOC 2, HIPAA, ISO 27001, and ISO 42001 compliant. Your job is to take it further. You'll own Sendbird's comprehensive information security programs, manage and evolve our compliance frameworks, partner with engineering, and continuously build a security culture that's embedded in how we work — not bolted on as an afterthought. You'll champion defense-in-depth philosophy, ensuring a multi-layered approach to security that protects our customers, our data, and our reputation.

You'll also own global IT Operations — managing our IT infrastructure, networks, servers, and data, while supporting our expanding use of AI technology across internal systems and how we work. As the primary executive responsible for safeguarding our AI-first innovation, you'll scale our global internal business systems and maintain our position as the most trusted platform for the world's most demanding enterprises.

You'll lead the team, own how we secure our infrastructure, respond to incidents, and hold our position against an increasingly complex threat landscape. This is a hands-on builder role — not a talking-head role.

You might be this person if

• You’ve managed or mentored a global security team and taken genuine pride in developing the people around you
• Are organized and methodical with strong attention to detail and an ability to analyze and interpret information
• You thrive in ambiguity and build structure where none existed
• Your instinct when something goes wrong is to fix, document, and improve—not assign blame
• You treat security as a conversation with the business, not a monologue at it
• You’ve started using AI tools to work faster—and you’re curious about what that means for the security programs you’re building

You need to have
