About this role

Job Summary

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 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 Gen-AI video briefings, and deploy at the most relevant time, enabling employees to make the best security choices everywhere they work.

As a software engineer intern, you will work hand-in-hand with our team to ship features to our customers on a fast, weekly cadence. You will build full-stack products, backend services, or data pipelines to integrate with our customers' datasets, enable data scientists to assess employee risks, and build systems to generate gen-AI videos at scale.

If you want to experience building and shipping real features at an early stage startup, Fable is the place for you.

We are an early stage startup, backed by Greylock Partners, the investors behind Palo Alto Networks, Okta, Rubrik, Figma, and others. Our team has built many of the iconic products at Meta, Twitter, Flexport, and more. Our team has alumni from CMU, Waterloo, Columbia, Berkeley, Purdue, Stanford, and USC.

Job Responsibilities

- Analyze security data and implement data pipelines to improve our employee behavioral profile system

- Write organized and well-tested Python code

- Work with our founders and mentor engineers to understand product requirements and design systems

- Validate your features end-to-end in a production environment

- Understand and debug our backend database schemas, data pipelines, etc.

As an intern at an early-stage company, you'll be doing the same work as our full-time engineers and be responsible for shipping real projects to production.

About this listing

Published on Ashby under the board identifier Fable, which is the name the employer’s own job board carries. RoleSprint has not verified the company’s registered or trading name, so it is shown exactly as published rather than tidied up.

RoleSprint is not the employer and not a recruiter. Applications are made on the employer’s own site and never reach us; what RoleSprint does is help you decide whether a role is worth your time and prepare for it if it is.
