## Job description

WHY AISLE?

Aisle is redefining how enterprises secure their software with an AI agent for autonomous vulnerability remediation. Vulnerabilities are the #1 root cause of cyber incidents, yet most organizations take weeks or months to patch what attackers exploit in days. We’re changing that.

Our mission is to protect democratic societies from the most sophisticated cyberattacks. We do that by giving organizations - including those operating critical infrastructure - the power to harden their systems and resolve security issues at superhuman speed and scale. Backed by world-class founders and advisors, we’re creating a new category in cybersecurity at the intersection of AI, automation, and enterprise resilience.

We’re a small, talent-dense team spread across the Europe, 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 experience in back-end engineering with Python (or similar high-level language)
- Expertise in building scalable, distributed systems and microservices architectures
- Strong experience with cloud platforms (AWS preferred) and containerized environments (Docker, Kubernetes)
- Familiarity with databases (SQL/NoSQL) and messaging/queueing systems
- Hands-on experience with CI/CD pipelines and automated testing practices
- Solid understanding of secure coding principles and interest in cybersecurity
- Bonus: background in AI/ML integration, data pipelines, or enterprise SaaS products

## WHAT YOU’LL DO

- Drive end-to-end development of back-end components: design, implementation, testing, deployment, and monitoring
- Contribute to architecture and technical design decisions for scalable, distributed systems
- Build and optimize APIs and services to support AI-driven vulnerability detection and remediation
- Improve the efficiency, scalability, and security of our core platform
- Collaborate with front-end, AI research, and DevOps teams to deliver features end-to-end
- Participate in code reviews, knowledge sharing, and mentoring within 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.
