## Job description

## 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.

## What You’ll Do

- Build high-quality, responsive interfaces using React, Next.js, and modern web tech
- Own features end-to-end, including backend logic and data layers when needed
- Collaborate with design and product to turn ideas into customer-ready experiences
- Engage with early users, learn from feedback, and iterate quickly
- Contribute to a strong engineering culture through code reviews, shared ownership, and mentorship
- Ship production-grade code quickly and thoughtfully — balancing quality and speed

## Who You Are

- 3–5 years of experience building and shipping fullstack or frontend-heavy applications
- Strong fluency with React, Next.js (or similar frameworks), and frontend fundamentals
- Experience implementing backend logic and persistence — ideally with Django or similar
- Familiar with TypeScript and GraphQL (or excited to grow into them)
- Proven ability to take features from concept to production independently
- Customer-obsessed — you care that your work solves real problems for real users
- Thoughtful about UX and usability, and ask good product questions
- Thrive in fast-paced, high-ownership environments
- Continuously raise the bar — for yourself, your peers, and the product

You might be a great fit if... You've built production features in a fast-moving environment, love sweating the details of user experience, and take pride in solving real-world customer problems.

The estimated salary range for this position is estimated to be $135,000 - $220,000/year. Total compensation for this position may also include Restricted Stock units, sign-on bonus and other potential future incentives.
