About Parloa
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.
About the role:
Security at Parloa isn't an afterthought — it's foundational to how we build and operate an AI platform that enterprises trust with sensitive voice and chat data at scale. As Principal Security Engineer, you'll set the technical direction for security across our engineering organisation: from secure architecture and threat modelling, to embedding security thinking into how a fast-growing AI company designs, builds, and ships.
This is a hands‑on, high‑ownership role. You won't just maintain a security programme — you'll define it, working across infrastructure, product, and AI/ML teams to ensure security is built in from the start, not bolted on afterwards. You'll be a technical authority and a multiplier, raising the security bar across the whole organisation.
Areas of ownership:
Own the technical security engineering strategy across Parloa's platform, infrastructure, and AI/ML systems
Lead deep threat modelling 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
Who you are:
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
* We provide equal opportunities to all qualified applicants regardless race, gender, sexual orientation, age, religion, national origin, disability status, socioeconomic background and other characteristics.
Parloa is committed to upholding the highest data protection standards for our clients' and employees' data. All our employees are instrumental in ensuring the utmost care, GDPR, and ISO compliance, including ISO 27001, in handling sensitive information.
