About ElevenLabs
ElevenLabs is a research and product company defining the frontier of audio AI. Millions of people use our technology to read articles, voice over videos, and restore voices lost to disability. Leading developers and enterprises worldwide use ElevenLabs to build intelligent agents for support, sales, and education.
We launched in January 2023 with the first AI model to cross the threshold of human-like speech. In January 2025, we raised a $180 million Series C round, valuing the company at $3.3 billion. By September 2025, that valuation doubled to $6.6 billion as we surpassed $200 million ARR in under three years.
Our mission is to build the most important audio AI platform in the world, solve AI audio intelligence, and make information accessible in any voice, language, or sound.
Our core offerings are our Creative Platform and the Agents Platform, powered by proprietary Text to Speech, Speech to Text, and conversational AI models.
We are just getting started. If you want to work hard and create lasting impact, we would like to hear from you.
How we work
High-velocity: Rapid experimentation, lean autonomous teams, and minimal bureaucracy.
Impact not job titles: We don’t have job titles. Instead, it’s about the impact you have. No task is above or beneath you.
AI first: We use AI to move faster with higher-quality results. We do this across the whole company—from engineering to growth to operations.
Excellence everywhere: Everything we do should match the quality of our AI models.
Global team: We prioritize your talent, not your location.
What we offer
Innovative culture: You’ll be part of a generational opportunity to define the trajectory of AI, surrounded by a team pushing the boundaries of what’s possible.
Growth paths: Joining ElevenLabs means joining a dynamic team with countless opportunities to drive impact - beyond your immediate role and responsibilities.
Learning & development: ElevenLabs proactively supports professional development through an annual discretionary stipend.
Social travel: We also provide an annual discretionary stipend to meet up with colleagues each year, however you choose.
Annual company offsite: Each year, we bring the entire team together in a new location - past offsites have included Croatia and Italy.
Co-working: If you’re not located near one of our main hubs, we offer a monthly co-working stipend.
About the role
We’re looking for an Application Security Engineer to join the ElevenLabs Security team. In this role, you’ll work at the intersection of security and software engineering, building systems and tooling that enable teams to ship secure software at high velocity.
You will:
Design and build application security tooling and guardrails that integrate directly into modern development workflows, including environments that heavily leverage AI-assisted and agentic coding
Partner with Engineering and Infrastructure teams to review application architectures, develop threat models and build in secure by default patterns throughout the software development lifecycle
Identify, prioritise and remediate application security vulnerabilities, working directly with engineers and contributing to fixes where required, across the entire stack.
Ship new security features which directly improve the security posture of our products in production
Design and implement supply chain security controls across build and deployment pipelines, including artefact signing, provenance, dynamic admission controls and SBOM generation
Requirements
Strong software engineering background, with experience building and shipping production systems
Proven track record of building and scaling security programs or developer security tooling from scratch
Fluency in Python and TypeScript with the ability to read, write and maintain production quality code
Hands on experience in cloud-native environments (AWS or GCP), Kubernetes, and infrastructure-as-code (Terraform)
Solid understanding of application security, including discovery, exploitation and remediation. You should understand how to prioritise fixes without relying on CVE scores alone
Experience driving real security improvements through technical design, implementation and secure defaults, rather than through policy or manual review alone
Bonus:
Experience securing AI or Machine Learning systems, including training pipelines
Background in developer experience or platform engineering, especially building developer tooling
Contributions to open source security projects, published research or talks at security conferences
Experience working in regulated environments (SOC 2, ISO27001, PCI, HIPAA or similar)
Location
This role is remote and can be executed globally. However, to facilitate working with the Security Team, we prefer candidates based in GMT to GMT+3 or UK. If you prefer, you can work from our offices in Dublin, London or Warsaw
