Security Engineer — Cryptanalysis / Reverse Engineering
AfterQuery
We're building a research cohort of senior domain experts in security — spanning cryptanalysis and reverse engineering — to help evaluate how frontier AI models reason about hard, real-world expert-level problems. This is research-and-evaluation work, not production engineering: you'll be defining what "correct" and "excellent" look like on problems you already know deeply. Requirements Domain: Security Experience: 6–10 years Education: Bachelor's Degree (Master's preferred) Candidates who meet the requirements and provide the requested materials will be prioritized for review. As part of this process, we conduct thorough background checks. Please apply only if you meet these requirements — candidates who meet fewer than 70% of the stated qualifications may be flagged for misrepresenting their professional experience, which could affect eligibility for future project staffing.
