Hiring: Senior AI Researcher Company: Assail Location: Boston, NY Job Posted Time: 2026-09-03 10:26:00 Employment Type: Remote Target Skills & Keywords : Data Pipeline, Fine-tuning, LLM, OWASP, PyTorch, Python, REST About the job Experience: •26 years of offensive security experience, contributions to the OWASP API Security Top 10, and a permanent exhibit at The Mob Museum. Required Skills: •This is a research role, not an applied ML role. You'll own original research on offensive security agents — how they reason, plan, use tools, and operate autonomously over long horizons. You'll design experiments end-to-end, build the evaluation infrastructure the field doesn't yet have, and translate research wins into capability that ships. •The feedback loop is fast and adversarial. Research that proves out goes into production. Research that doesn't gets killed quickly so the next bet can start. •Drive original research on offensive security agents — reasoning, planning, tool use, and autonomous long-horizon operation •Advance Dagger's post-training pipeline: supervised fine-tuning, RL from verifier signals, LoRA adaptation, and evaluation against adversarial benchmarks •Extend Javelin's co-evolutionary self-training architecture: curriculum design, self-play dynamics, and reward modeling for security-specific outcomes •Design and execute experiments end-to-end, from hypothesis through writeup •Build internal evaluation harnesses that measure capability rigorously, where no public benchmark exists •Translate research into production handoffs to AI Engineering — model cards, deployment notes, and known failure modes Compensation: •Competitive base salary and meaningful early-stage equity Interested candidates, please apply directly through the job posting on company's career page or try via AI auto apply on this platform.
