## About the Role

As a Senior FullStack Engineer, you’ll join our engineering team and help build the next generation of Irregular’s products as they evolve into intuitive, polished, and powerful experiences for some of the most sophisticated AI organizations in the world. This is a highly impactful role for an engineer with strong frontend expertise who cares deeply about product quality and user experience, and can both build scalable systems and help lead the technical direction of the frontend. You’ll work closely with exceptional engineers, researchers, and founders to turn deeply technical capabilities into user-facing products that are clear, elegant, and highly effective. Representative Responsibilities:

- Build and own full-stack product features end-to-end
- Help shape the next generation of the company’s products
- Lead the technical direction of the frontend architecture, development standards, and engineering culture
- Build polished, high-quality user experiences for highly technical users
- Collaborate closely with engineers, founders, and product stakeholders on product and technical decisions
- Take ownership of projects from idea to production with high autonomy and impact

What we're looking for:

- Strong full-stack engineering experience with deep frontend capabilities
- Hands-on frontend experience with React/Angular/TypeScript and modern frontend frameworks
- Backend development experience with scalable production systems
- Ability to work independently and lead projects from idea to production
- Strong product intuition and passion for building exceptional user experiences
- Comfort working closely with designers and building polished, pixel-perfect UIs across devices and screen sizes
- Commitment to code quality, maintainability, and testing as part of the development process

## 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.
