About Fable Security
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.
Why Join Us
Build and scale the foundational data infrastructure powering a category-defining product

Ensure data quality, observability, and reliability across pipelines
Optimize systems for performance, cost, and scalability
Build tooling to support reproducible datasets and experimentation
Partner with data scientists and engineers to productionize ML and analytics workflows
Contribute to secure and compliant data infrastructure in cloud environments
Your Skillset: Must-Have
3–7+ years of experience in data infrastructure, infrastructure, or platform engineering
Strong understanding of real-time and batch data processing systems, including stream processing, messaging architectures, and large-scale data workflows (Spark, Kafka, etc.)
Experience with modern data tooling (dbt, Airflow, etc.)
Strong understanding of data modeling, ETL/ELT, reverse ETL, and orchestration
Experience designing for scalability, reliability, and observability
Hands-on experience with cloud platforms (AWS/GCP) and storage systems
Ability to operate in a fast-moving startup environment with high ownership
Nice-to-Have
Familiarity with ML infrastructure or feature stores
Experience with data versioning, lineage, or reproducibility systems
Background in security, compliance, or high-sensitivity data domains
Previous experience at an early-stage startup
How We Work
We value impact over process—you’ll ship quickly and iterate
Engineers have high ownership and autonomy
We operate with tight feedback loops across product and engineering
We prioritize technical rigor, simplicity, and long-term scalability
Compensation & Benefits
Competitive salary + equity
Health, dental, vision coverage
Flexible PTO
