Overview

Project Fenrir asks researchers to uncover genuine security flaws inside private code repositories and shape each finding into a cybersecurity task that tests frontier LLMs at a set difficulty. You will work across C/C++, Rust, and Go codebases, using fuzzing and crash triage to confirm which issues deserve a task. The listed compensation is $100.00/hr, and Project Fenrir adds per-approved-task, per-repository, referral, and milestone bonuses. The role sits inside AfterQuery's software engineering group and carries a remote work arrangement.

What You'll Do6

Hunt for genuine vulnerabilities in private repositories written in C, C++, Rust, and Go.
Reproduce candidate flaws and triage crashes to separate real security issues from false positives.
Build fuzzing inputs or test harnesses that trigger each issue and show its impact.
Read unfamiliar codebases to trace how a bug reaches a vulnerable path.
Turn each confirmed finding into a cybersecurity task with a defined difficulty level for frontier LLM evaluation.
Submit completed tasks for in-band review and refine write-ups until they meet Project Fenrir approval standards.

Requirements4

Background in security research or vulnerability discovery, with examples of flaws you found.
Comfort with fuzzing and crash triage, including the ability to isolate root causes from crash data.
Ability to read and audit C, C++, Rust, and Go codebases.
Skill at documenting a technical finding so another engineer can reproduce it and gauge its difficulty.

Who Should Apply

Security researchers who can point to real vulnerabilities they discovered and explain the fuzzing or triage path that surfaced them. You should read C/C++, Rust, or Go with enough depth to judge whether a crash hides a serious flaw. Candidates who like turning raw findings into structured evaluation tasks will get the most from this work.

Salary Insight

The posting lists $100.00/hr. Project Fenrir also pays per in-band approved task and per qualifying repository, then adds referral and milestone bonuses, so total earnings depend on review outcomes and how many repos you cover.
