From the original posting

Role

Origin is seeking an AI Security Researcher to investigate the evolving intersection of adversarial tradecraft and modern generative AI systems. This role focuses on understanding how attackers misuse or weaponize LLMs, on-device assistants (such as Computer Use Agents), autonomous agents, code-generation models, and multi-modal AI systems, and on translating this research into impactful defensive capabilities within Origin’s products.

Success in this role requires deep curiosity, strong technical intuition, hands-on experimentation, and the ability to convert ambiguous research signals into clear, actionable engineering outcomes.

Responsibilities

  • Conduct in-depth research into how modern adversaries may evolve tradecraft to exploit or abuse generative AI tools, including LLMs, autonomous agents, and on-device assistants

  • Conduct hands-on research into adversarial prompting, jailbreak methods, tradecraft leveraging computer use agents and local models, and other AI-enabled attack vectors

  • Translate and implement research findings into actionable improvements for Origin’s products

  • Produce high-quality, public-facing security research content, including blog posts and conference talks

  • Stay abreast of cutting-edge offensive and defensive security techniques through continuous self-study and research

  • Serve as the subject matter expert in adversary tradecraft and security operations, supporting other business units on their projects as needed

  • Support other Researchers on the team with their research and actively engage in team-driven initiatives

Skills and Experience

  • 5+ years of experience in one or both of the following areas:

    • Offensive security research, such as red team operations or purple teaming

    • Defensive security research, for purposes of publication and security feature development

  • Ability to write code for development of research tooling

  • Ability to explain complex technical concepts and research outputs to both executive-level and highly technical consumers

  • Aptitude for working in a fast-paced, adaptive startup environment

Nice to Haves

  • Demonstrated experience investigating or exploiting generative AI systems, prompt engineering, jailbreaks, model exploitation, or agentic misuse

  • Familiarity with reinforcement learning, model interpretability, or safety research

  • Contributions to open-source AI or security tooling

  • Prior publications, conference presentations

  • Proficient in at least one systems language (Rust, C/C++)

  • Knowledge of operating system internals and reverse engineering
