About the Role

Security at Parloa is foundational to building and operating an AI platform that enterprises trust with sensitive voice and chat data at scale. As Principal Security Engineer, you will set the technical direction for security across the engineering organization, from secure architecture and threat modeling to embedding security thinking into the design, build, and shipping processes of a fast-growing AI company. This is a hands-on, high-ownership role where you will define the security program, working across infrastructure, product, and AI/ML teams to ensure security is built in from the start. You will be a technical authority and a multiplier, raising the security bar across the entire organization.

Responsibilities

Own the technical security engineering strategy across Parloa's platform, infrastructure, and AI/ML systems
Lead deep threat modeling and architecture reviews for new and existing systems, including LLM-based and voice/chat AI pipelines
Drive secure-by-design practices into the software development lifecycle, partnering closely with engineering teams rather than gatekeeping after the fact
Design and improve detection, monitoring, and incident response capabilities across cloud and AI infrastructure
Guide security architecture for multi-tenant, sensitive data flows across Parloa's enterprise customer base
Support compliance and governance efforts (e.g. SOC 2, ISO 27001) by ensuring technical controls are sound and well-documented
Mentor senior+ engineers and security practitioners, building security capability across the wider organisation
Act as a trusted technical voice in conversations with enterprise customers and partners on security matters
Stay ahead of the evolving threat landscape for AI and voice/chat systems, bringing new risks and mitigations to the team proactively

Requirements

Extensive experience (15+ years) in security engineering, with demonstrated impact at Staff or Principal level
Deep expertise in application security and/or cloud security, threat modelling, and secure architecture for distributed, cloud-native systems
Hands-on experience with cloud security across AWS, GCP, or Azure, and container orchestration (Kubernetes)
Strong understanding of identity and access management, encryption, and secure data handling at enterprise scale
Experience securing systems handling sensitive or regulated data, ideally with exposure to GDPR or similar frameworks
A track record of driving security strategy and influencing engineering culture across an organisation, not just executing individual fixes
Excellent communication skills, able to explain security risk and trade-offs clearly to engineers, leadership, and customers
Genuine curiosity about AI systems and a willingness to dig into the emerging security challenges they introduce

About the Company

Parloa is building the next generation of agentic AI for enterprise customer experience. Our Conversational Platform powers real-time voice and chat AI agents that handle complex, natural conversations at scale for some of the world's largest enterprises.
We recently closed a $350M Series D at a $3B valuation, and we're scaling fast — across product, infrastructure, and the global enterprises who trust us with their most sensitive customer interactions.
We’re at the beginning of a new era in customer experience, one where AI doesn’t just respond, but understands, reasons, and takes action. We’re building agentic AI that enterprises trust with their most important customer moments: complex questions, high volumes, real stakes.
When millions of people reach out to a brand, those interactions aren’t just support tickets; they’re defining experiences. We’re here to raise the standard: making every conversation seamless, intelligent, and genuinely helpful.
At Parloa, ownership isn’t a buzzword; it means being accountable for outcomes, not just tasks. We operate in a category that’s evolving fast, where the bar is high, and the problems are complex. We hire people who think in solutions, communicate with clarity, and follow through. People who are comfortable making decisions, taking responsibility, and raising the standard for themselves and those around them.
We’ve grown beyond the earliest startup phase, but we’ve kept the intensity: fast execution, direct feedback, and a strong expectation to contribute meaningfully from day one.
Backed by leading global investors like General Catalyst, EQT Ventures, and Altimeter Capital, we’re scaling with a clear ambition: to become the global category leader in enterprise-grade conversational AI.
