Backend Engineer

Fable Security is tackling the most critical challenge in cybersecurity: human errors. Human error is the #1 cause of security breaches, yet employees lack effective ways to learn what they need to stay secure. Fable is here to change that.

Fable’s mission is to prevent cyber attacks (ex 1, ex 2, ex 3) by harnessing AI to transform human behavior and improve human defenses. We use the best practices from GenAI and behavioral systems to automatically identify your employees at risk, curate hyper-personalized video briefings, and deploy at the most relevant time, enabling employees to make the best security choices everywhere they work. This is a multi-billion-dollar market, and every company—from SMB to Fortune 500 enterprises—is racing to combat this problem.

Since founding, we've seen strong demand and adoption from customers, reaching thousands of employees worldwide with our personalized video briefings and security insights.
Our team works from our San Francisco office 3 days a week, and places high value on mutual trust, execution, and delivering highly differentiating product experiences and results to our customers.

You will own and develop the backend systems to serve our API, customer integration layer, data services, video generation infrastructure, and customer portal. You want to design and build foundational systems and end-to-end products on top of them. You take pride in building reliable, maintainable, and scalable services. You can transform product requirements into designs and systems that anticipate our needs as we evolve. You take pride in impact, and make judgment calls on how to build with consistent progress.

Fable is founded by the early team from Abnormal Security ($5B+ valuation) and backed by one of the top VCs in cybersecurity. Our team has alumni from Waterloo, Columbia, Berkeley, Purdue, CMU, Stanford, and USC.
