## Job description

## About Irregular

Irregular is the first frontier security lab with the mission of protecting the world in the time of increasingly capable and sophisticated AI systems. We build next-generation defenses through high-fidelity research platforms that simulate and monitor real-world AI security scenarios. As AI systems become more powerful, we focus on staying ahead of emerging threats and vulnerabilities, ensuring these transformative technologies can be deployed safely and securely.

## About the Role

We’re looking for a highly organized, proactive, and discreet Personal Assistant to support Irregular’s CTO and Co-Founder across his personal and professional life. This is a hands-on role with a high degree of ownership and autonomy. Approximately 70% of the role focuses on personal matters, household and family coordination, travel, and day-to-day logistics. The remaining 30% involves calendar management and professional and administrative support. You’ll anticipate needs, manage competing priorities, and make sure things get done, from everyday errands to complex arrangements. The role requires sound judgment, absolute discretion, and flexibility to respond outside standard working hours when needed.

## Key Responsibilities

Personal Support (~70%)

- Manage personal matters and errands end-to-end, including appointments, transportation, special projects, and ad hoc requests.
- Coordinate household operations, service providers, and vendors, ensuring reliable execution and follow-through.
- Manage family logistics and children’s schedules, including school administration, after-school activities, and appointments.
- Plan and coordinate personal and business travel, including flights, accommodation, transportation, visas, and detailed itineraries. Handle changes and unexpected issues as they arise.
- Organize personal events and activities, taking ownership of planning, coordination, and execution.

Professional Support (~30%)

- Own the CTO’s work and personal calendars, anticipating scheduling conflicts, managing priorities, and protecting time for focused work.
- Coordinate internal meetings across the company and external meetings with partners, clients, and other stakeholders.
- Manage expense reports, invoices, and billing for personal and professional matters, working with the Operations team where relevant.

## Requirements

- 2+ years of experience as a Personal Assistant, Executive Assistant, or in a similar role in a fast-paced environment, ideally supporting senior executives.
- Exceptional organizational skills and attention to detail, with reliable follow-through across multiple tasks and deadlines.
- Ability to take ownership, anticipate needs, and solve problems independently with minimal guidance.
- Sound judgment and absolute discretion when handling sensitive personal, family, and business information.
- Strong interpersonal and communication skills, with the ability to build trusted relationships with family members, colleagues, service providers, and vendors.
- Ability to stay calm, adapt quickly, and prioritize effectively as plans and needs change.
- Fluent Hebrew and English, both written and spoken.
- Willingness to handle personal errands and household logistics hands-on, and availability outside standard working hours when required.

## Nice to Have

- Experience in a senior administrative or operational role in the IDF, such as Head of Bureau or Chief of Staff.
- Experience using AI tools and productivity apps to streamline planning, coordination, and administrative work.
- Experience working in a startup or technology company.

## About Irregular

## Company Overview
- **One-liner**: Irregular is the world’s first frontier security lab, building next-generation defenses to protect the world from increasingly capable and sophisticated AI systems.
- **Entity Type**: Private (Series A)
- **Headquarters**: Tel Aviv, Israel
- **Founded**: 2023
- **Founders**: Dan Lahav (CEO) and Omer Nevo (CTO)

## Core Business
- **Primary industry/industries**: AI Security / Cybersecurity
- **Target customers**: B2B – Primarily the world’s leading AI labs (Anthropic, OpenAI, Google), enterprises deploying advanced AI, and governments (including the UK government).
- **Mission or purpose statement**: “Protecting the world in the time of increasingly capable and sophisticated AI systems.”

## Products & Services
- **Frontier AI Security Platform**: A high-fidelity research platform that simulates and monitors real-world AI security scenarios. The platform analyzes models, simulates attacks, and identifies new types of vulnerabilities to build next-generation defenses. The core offering focuses on “model control” – securing AI systems from within, rather than traditional perimeter defenses.

## Market Standing
- **Valuation/Market Cap**: Not publicly disclosed
- **Key Metric**: **$80 million in total funding** (as of September 2025); the company became **profitable in 2025**.
- **Notable Investors/Partners**: Sequoia Capital, Redpoint Ventures, Swish Ventures (Omri Caspi), and prominent angel investors including Wiz founder Assaf Rappaport and Ofir Ehrlich (Eon). Clients include Anthropic, OpenAI, Google, and the UK government.
- **Growth Signals**: Named **#1 Most Promising Startup in Israel (2026)** by Calcalist and CTech’s annual Top 50 list. Recognized on the **AI 50 Brink list (2026)**. Signed multiple seven-figure contracts in 2025. The founders report constant inbound interest from investors, receiving proposals “every day, non-stop.”

## Competitive Advantages
- **First-mover & unique positioning**: Irregular is the first company explicitly founded as a “frontier security lab” focused exclusively on the security of advanced AI systems, positioning itself as the “Check Point of the AI revolution.”
- **Deep integration with top AI labs**: The company holds a contract signed by Anthropic’s founder Dario Amodei, and works directly with OpenAI and Google, giving it unparalleled access to and insight into the most advanced AI models.
- **Research-driven approach**: The team has demonstrated groundbreaking research, including showing that two AI agents can communicate and collaboratively bypass their own safety safeguards.
- **Talent density**: The small team (approx. 40 employees) is described as “talent-dense,” comprising AI scientists published in top venues, senior leaders who have scaled R&D organizations into the hundreds, world debate champions, and top cyber and national security experts.

## Strategic Focus
- **Primary focus**: Building a foundational, large-scale company akin to Palo Alto Networks or CrowdStrike, but for the AI era. The core strategic bet is that traditional cybersecurity paradigms are broken by AI, and the future lies in “system control” – securing AI models from the inside.
- **Growth direction**: Scaling the team and platform to meet exploding demand from AI labs, enterprises, and governments. The company is actively hiring across research, engineering, and policy roles to accelerate product development and expand into new verticals.

## Why Work Here
- **Mission-driven work**: The opportunity to work on what the founders describe as “the defining problems of AI security” and to build the defenses that will keep advanced AI secure for the world.
- **Elite, talent-dense team**: Work alongside AI scientists, top cyber experts, and senior leaders from the world’s most prestigious institutions. The culture emphasizes curiosity, high standards, and intellectual rigor.
- **Resources & backing**: Backed by top-tier investors (Sequoia, Redpoint) with significant funding ($80M), and already profitable, providing strong stability and runway.
- **Work policy**: Hybrid workspace in Tel Aviv, Israel. Most roles are listed as “In-Office” or hybrid with a typical expectation of on-site presence.
- **Hiring process**: A structured, multi-stage process designed to reduce bias and allow candidates to showcase their strengths. Stages include an exploratory chat, a take-home assignment (approx. 5 hours) or online interview, a day of 2-3 technical interviews, and a leadership fit interview. The company is committed to moving swiftly and accommodating candidate timelines.
