Fullstack Engineer

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 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.
