About the role

Your Role

As a Platform / Infrastructure Engineer, you will build and scale the core systems that power Fable’s product and data workflows.

You’ll work across backend systems from real-time services to data pipeline. You’ll ensure reliability, scalability, and performance across the stack. You’ll collaborate closely with data and ML teams and contribute to the systems that ingest, process, and serve data.

This is a highly cross-functional role where you’ll partner with engineering, data, and product teams to build robust, production-grade systems that scale with the company.

Responsibilities

Design, build, and operate scalable backend and infrastructure systems
Develop and maintain services that support real-time and batch data processing
Contribute to core platform components (compute, storage, orchestration, and tooling)
Improve system reliability, observability, and performance across services and workflows
Collaborate with data and ML teams to support data ingestion, processing, and production use cases
Optimize systems for scalability, cost, and efficiency in cloud environments
Build internal tools and abstractions that improve developer velocity and system consistency
Contribute to secure and compliant infrastructure design

Why This Role Matters

Data is core to the product. You’ll be responsible for building the systems that enable:

Reliable, production-grade data for customers and internal teams
Real-time decision-making
Scalable analytics and experimentation

Your work will directly impact how the company builds, ships, and scales.

AI-driven threats and human error are today’s biggest enterprise security risks. Cybercriminals don’t hack systems—they exploit people. Human errors drive 70% of security breaches, making human behavior the primary and growing attack surface. At Fable, we believe that the right tools can convert people from targets to another layer of defense.

Fable is the human risk platform that directly shapes employee behavior. Designed for simplicity and enterprise scale, our agentic platform synthesizes complex employee data, pinpoints risky behaviors, and deploys highly relevant interventions to people automatically, in real time, right where they work.

Backed by Redpoint Ventures and Greylock Partners and founded by early Abnormal Security team members, Fable is solving cybersecurity’s biggest challenge in a multi-billion-dollar market. Our team includes alumni from Meta, Twitter, Flexport, and top-tier universities like Waterloo, Columbia, Berkeley, Purdue, CMU, Stanford, UCLA, and USC. We are experiencing explosive growth, making this a career-defining opportunity to join and shape the future of security.
