Fenrir Security Researcher

What you'll do

Project Fenrir is a security research pipeline. You look for real vulnerabilities in private repositories and convert them into cybersecurity tasks whose difficulty is probed against frontier language models. The ad calls them "difficulty-probed", which suggests a task counts only if it lands in a target difficulty band for the models being tested.

The ad is brief and does not describe the review process, the repositories, or how many tasks to expect.

Who fits

• Security research or vulnerability discovery experience
• Comfort with fuzzing and crash triage
• Comfort reading C, C++, Rust and Go codebases

No years of experience, degree or location is stated.

What it pays

The board shows $100/hr, but the ad's own description is different: contributors earn per in-band approved task, per qualifying repository. So the hourly figure is a headline equivalent, not a wage. Your real hourly rate depends on how fast you find a usable vulnerability and how often the task is approved within the difficulty band. The listing does not publish its payment terms.

Worth knowing

Good:

• Real vulnerability research on real code, rather than synthetic puzzles
• A rare fit for people who already do fuzzing and crash triage
• Output-based work that rewards speed and skill

Less good:

• Per-task pay means no guaranteed hourly income; time spent on a repository that yields no approved task may go unpaid
• "In band" means a task can be rejected for being too easy or too hard for the models
• Scope, payment terms and hours are not stated in the ad

About this listing

Read from the AfterQuery Experts board on 18 October 2026 (posted 1 September 2026). The work involves security vulnerabilities, so this listing describes the role only. AfterQuery's help centre describes an unpaid, one-attempt assessment and ID verification for its expert pools. See AfterQuery.
