AISLE is building the AI that finds, fixes, and verifies software vulnerabilities autonomously - an end-to-end system that closes the gap between when a vulnerability appears and when it's safely patched. Vulnerabilities are the #1 root cause of cyber incidents, yet most organizations take weeks or months to remediate what attackers now exploit in days. We're ending that backlog. Our systems already find and fix vulnerabilities in the world's most heavily audited codebases - 375+ independently validated CVEs across projects like OpenSSL, curl, Linux, and Chromium - at machine speed and superhuman scale. AISLE runs entirely inside our customers' perimeter (cloud, on-prem, or fully air-gapped) and can run on our optimized models or theirs, so even the most sensitive organizations, including those operating critical infrastructure, stay in full control of their code and their models. Backed by world-class founders, advisors, and angel investors, we're defining a new category: sovereign, AI-native security. Our goal isn't to improve vulnerability management - it's to end the backlog and move toward a future where software defends itself. We’re a small, talent-dense team spread across Europe, the US and Canada. We value high ownership, high velocity, and low-ego collaboration. If you want to work with world-class minds in AI and security, thrive in fast-moving environments, and care about solving one of the toughest challenges in tech, Aisle is the place for you. ## What we're looking for - 3+ years of professional software engineering experience spanning both frontend and backend development. - Strong backend foundation: Experience with Python (or similar high-level languages) building scalable services or APIs. - Modern frontend expertise: Deep familiarity with TypeScript and hands-on experience with modern component frameworks—Svelte, React, or Vue. We primarily use SvelteKit to build highly responsive, intuitive user interfaces. - Automated Testing Rigor: Strong experience writing and maintaining automated test suites across the entire stack. This includes backend unit/integration testing (e.g., pytest) and frontend testing (e.g., Vitest, Testing Library, Playwright, or Cypress). - System & Cloud architecture: Experience with cloud platforms (AWS preferred), containerized environments (Docker), and basic microservices architectures. - Data & Messaging: Familiarity with databases (SQL/NoSQL) and modern API design (REST, GraphQL, or gRPC). - DevOps & Quality: Experience with CI/CD pipelines, automated testing (both backend unit tests and frontend integration/E2E testing), and version control. - Security Mindset: A solid understanding of secure coding practices (OWASP top 10) and a genuine interest in cybersecurity. - Bonus: Experience with data visualization libraries (like D3.js), AI/ML API integration, or building enterprise SaaS products. ## What you’ll do - Own features end-to-end: Design, implement, test, and deploy features across the entire stack—from database schemas and Python microservices to polished Svelte frontend components. - Build AI-driven interfaces: Design and optimize APIs and interactive frontend experiences that make complex, AI-driven vulnerability detection and remediation intuitive for users. - Collaborate on architecture: Contribute to technical design decisions for both scalable backend distributed systems and modular, performant frontend state management. - Bridge the gap: Work closely with AI research and DevOps teams to seamlessly integrate complex data models and pipelines into the user-facing application. - Maintain high standards: Participate in comprehensive code reviews, write clean and testable code across the stack, and share frontend/backend best practices with the team. ## About Aisle ## Company Overview - **One-liner**: AISLE is an AI-native vulnerability management platform that autonomously discovers, fixes, and verifies software vulnerabilities at machine-superhuman speed. - **Entity Type**: Private (Angel-stage – raised an angel round in October 2025 from 6 undisclosed investors) - **Headquarters**: San Francisco, California, United States (also a major hub in Prague, Czech Republic) - **Founded**: 2024 - **Founders**: Ondrej Vlcek (CEO) and Stanislav Fort (Chief Scientist) ## Core Business - **Primary industry**: Computer and Network Security / Cybersecurity (vulnerability management) - **Target customers**: Enterprise organizations with complex, heavily audited codebases (B2B) - **Mission or purpose**: Build self-defending systems that secure the digital backbone of modern life — autonomously, intelligently, and at scale. The company’s measurable goal is **zero exploitable vulnerabilities**. ## Products & Services - **AISLE Snapshot**: On-premises, cloud, or fully air-gapped security scanner that delivers frontier-class detection in hours. It runs inside the customer’s perimeter (AWS, GCP, Azure, self-hosted) and provides a fast picture of code health. *Type: On-prem/cloud SaaS.* - **AISLE Enterprise**: Full-featured enterprise platform offering AI-native vulnerability management with flexible deployment, SSO, and compliance support. Includes collaborative remediation workflow. *Type: SaaS.* - **Autonomous Cyber Reasoning System**: End-to-end system that finds, fixes, and verifies vulnerabilities at scale — reducing mean time to remediation from 135 days (industry) to **4 days** in collaborative mode. *Type: AI/ML service.* ## Market Standing - **Valuation/Market Cap**: Not disclosed (private company) - **Key Metric**: **225+ CVEs** discovered (highest of any AI security platform); **85% fix acceptance rate**; **95% noise reduction** vs. traditional AppSec tools; **10x cost-efficiency** vs. Mythos. - **Notable Investors/Partners**: Angel investors include **Jeff Dean** (Google), **Thomas Wolf** (Hugging Face), **Olivier Pomel** (Datadog), **Aparna Chennapragada** (Microsoft), **Ian Goodfellow** (DeepMind), **Dwarkesh Patel**. Advisors: Prof. **Surya Ganguli** (Stanford), **Aernout Reijmer** (ex-ASML CISO), **Bruce Schneier** (Harvard), **Jaya Baloo** (COO/CISO). - **Growth Signals**: Headcount of 48 employees (monthly growth +3.8%); operates in 6 countries (US, Czechia, Poland, Switzerland, UK, Canada); credited for surfacing 13 of 14 Open in one release. Recent angel round shows strong investor confidence. ## Competitive Advantages - **AI-native autonomy**: Unlike traditional AppSec tools, AISLE’s reasoning system finds, fixes, and verifies vulnerabilities without manual triage. - **Speed & accuracy**: 4-day MTTR vs. 135-day industry average; 95% noise reduction; 85% fix acceptance rate. - **Proven CVE output**: More CVEs discovered than any other AI security platform, validated independently. - **Flexible deployment**: Can run in air-gapped, on-prem, or public cloud environments, meeting strict compliance needs. ## Strategic Focus - **Zero exploitable vulnerabilities** as an achievable outcome, not just a slogan. - **Ending the vulnerability backlog** by closing the loop between detection and remediation. - **Expanding enterprise adoption** and building partnerships with security-conscious organizations. - **Continued investment in AI research** (Chief Scientist Stanislav Fort leads frontier reasoning work). ## Why Work Here - **Remote-friendly culture**: Hubs in San Francisco and Prague, plus remote colleagues in the UK, Netherlands, Canada, and Switzerland. Open to extraordinary people anywhere. - **Meaningful equity**: Every employee is an owner and shares in the company’s success. - **Generous time off**: Real emphasis on recharging; unlimited PTO culture. - **Comprehensive benefits**: Medical, dental, mental health coverage; competitive compensation. - **Early-stage impact**: Small team (48 people) means every hire shapes the product and direction; direct access to founders and top-tier advisors (Jeff Dean, Bruce Schneier, etc.). - **Values-driven**: Six core values — Thoughtful, Honest, Resilient, Inclusive, Visionary, Empathetic — guide daily work. - **Open roles**: Currently hiring a Security Engineer; also accepts “Wild Card” applications for exceptional candidates. ## Sources 1.
