Senior AI Engineer, Tools & Agents

Who we are

Video is 90% of the worlds data. Most of it is invisible to machines.
TwelveLabs builds the intelligence layer to change that. Our multimodal AI models understand video the way humans do across sight sound and motion and power production-scale AI workloads across media entertainment sports security and government.

We have raised more than $210 million from NEA Radical Ventures Amazon NVIDIA Snowflake Databricks Index Ventures NAVER Ventures Korea Investment Partners Quadrille Capital Red Bull Ventures and AI pioneers including Fei-Fei Li Silvio Savarese and Alexandr Wang.

We are a global company headquartered in San Francisco with offices in Seoul New York and London and employees around the world. We believe the differences in our cultural educational and life experiences make our products stronger. Building technology that understands the world in all its complexity requires people who see it from every angle. We are looking for individuals who are driven by hard problems and want their work to matter. Come build it with us!

About the Role

TwelveLabs builds multimodal AI that understands video the way people do. Were looking for a product-minded senior backend engineer to build and own the platform and integration surfaces that bring our video-understanding capabilities to developers and AI agents.

Youll shape the APIs the agent-facing interfaces and the authentication authorization and multi-tenancy that make them production-grade and enterprise-ready. This is high-ownership high-craftsmanship work at the frontier of agentic AI with a direct line from what you build to what our customers and partners can do.

This role is hybrid based in our San Francisco office.

Candidates must be able to travel up to 10% of the time annually to attend conferences off-site meetings and other business-related events as required by the role. This role may require participation in on-site interviews and/or completion of in-person onboarding processes.

In this role you will

• Design and own developer- and agent-facing surfaces: public and partner APIs and agent integration interfaces such as MCP and agent-to-agent protocols.

• Build the authentication and authorization substrate: how users and machines authenticate and how access is enforced (RBAC organization and team scoping).

• Ship enterprise-readiness capabilities: organization support per-API-key usage tracking and metering and rate limiting designed around real system constraints rather than arbitrary defaults.

• Keep the platform reliable and scalable: define and uphold SLOs harden failure paths and keep services healthy under real-world and multi-tenant load.

• Move fast without compromising quality shipping to customers on a tight loop while holding a high craftsmanship bar.

• Collaborate closely with engineering and research partners to turn cutting-edge capabilities into durable product surfaces.

You may be a good fit if you have

• Strong backend engineering depth (typically 6 years) building and operating production services and APIs at scale.

• A track record of owning developer-facing or platform surfaces such as public APIs SDKs or integration layers with real care for API design and contracts.

• Hands-on experience with authentication and authorization in production: OAuth/OIDC RBAC multi-tenant isolation.

• Experience building enterprise/SaaS platform concerns: organization and team models usage metering rate limiting quotas.

• Demonstrable hands-on experience with agentic systems in production or through substantial personal projects with a strong grasp of agent tool design MCP and function-calling and the failure modes of LLM-driven applications.

• The judgment to ship fast and the craftsmanship to do it well with the maturity to know which one a given problem calls for.

Preferred Qualifications

• Shipped an agent or LLM-powered product that real users or developers depend on and can speak to what broke at scale and how you fixed it.

• Have taken a product from early access to enterprise-grade: the auth multi-tenancy and reliability work that turns a capability into something a large customer will trust.

• Contributed to the agent tooling ecosystem (for example open-source MCP servers or agent frameworks) or have a body of personal work that shows real fluency.
