Junior AI Security Researcher at A Security · Trevo
We are a fast growing cybersecurity startup redefining how organizations defend themselves. As attackers leverage AI for high speed strikes, we provide defenders with the same capabilities. Our platform creates an AI driven Autonomous Attacker that thinks like a hacker, generating end to end attack chains across Web, Cloud, and AI applications to prioritize mitigation where it matters. Founded a year and a half ago, we’ve moved at lightning speed raising a Seed from CyberStarts and a Series A from Lightspeed. With offices in Tel Aviv and New York, we maintain a high transparency, low ego environment where exceptional individuals have the autonomy to make a massive impact on a category defining product.
We're looking for a sharp, curious Junior AI Security Researcher to join the team at the beating heart of our Autonomous Attacker. Our platform is powered by AI agents running real attacks against real environments every day: Web, Internal Networks, External Networks, Cloud. You'll work hands-on with AI and data at every layer of our platform, learn the system deeply, and help push it forward on whatever front moves the needle most. This is a rare entry point into both offensive security and applied AI. No prior cyber background required, just a sharp analytical mind, obsessive attention to detail, and the courage to chase a question until it answers back.
What you'll do
Work hands-on with the AI agents at the core of our platform: study their behavior, their reasoning, their data, and the environments they operate in.
Mine large volumes of AI-generated data to surface patterns and opportunities that only show up at scale.
Use AI as your own force multiplier: write prompts, build evals, cluster findings, and move faster than humanly possible.
Experiment with prompt engineering, fine-tuning, model selection, and agent architecture to push the platform further.
Translate what you find into concrete improvements: write specs, open PRs, and ship them. You may well touch production code.
Push things forward. Pull the right people into the room, ask the "stupid" questions, and never let a thread die.
Requirements
Active student in Computer Science (or a closely related field).
High grades in analytical and quantitative subjects.
Thorough and detail-obsessed. Able to hold large amounts of noisy data in your head without losing the thread.
Strong ability to read data, extract conclusions, and communicate them crisply in writing.
Comfortable walking into brand-new technical domains and getting productive fast. Able to thrive in ambiguity.
Driver mentality. Comfortable pinging anyone in the company and pushing issues to resolution without waiting for permission.
Available for a meaningful weekly commitment, in-office in Tel Aviv.
Nice to have
Hands-on experience with LLMs (prompt engineering, agents, evals, fine-tuning, or RAG) in school projects or anything else.
Experience preparing data reports, dashboards, or analyses in a real setting (SQL, Python, BI tools).
Basic scripting (Python, SQL) sufficient to query data, prototype, and automate your own workflow.
Any exposure to cybersecurity (web, networks, red teaming, pentesting). Nice to have, not required.
Growth
This role is an entry point, not a dead end. Students who excel here grow into full-time positions across R&D (AI Research, Security Research, or Platform Engineering), picking the direction that fits what they discovered they're best at. We hire students we're excited to keep.
