Senior Frontend Engineer

Novee Security · telaviv

Description About Us N ovee is the AI penetration testing platform built for a world where attackers operate at machine speed. Founded in Tel Aviv in April 2025 by a team with decades of nation-state offensive security experience - including veterans of Unit 8200, Iron Dome, and elite zero-day research - we're turning that expertise into a platform that thinks like a real attacker, runs continuously, and uncovers the novel vulnerabilities that manual testers and scanners miss. We raised $51.5M in four months, backed by top investors YL Ventures, Canaan Partners, and Oren Zeev - one of the fastest funding trajectories in offensive security. Our proprietary AI model outperforms frontier LLMs by over 55% on real exploitation benchmarks, and we're just getting started. We're looking for exceptional people to join our mission: making continuous, intelligent offensive security the new standard. About the Role We’re hiring a Senior Full Stack Engineer to join our Platform team, currently made up of six engineers, and help build and scale the core product behind our AI-powered security platform. In this role, you’ll take end-to-end ownership of complex features-from designing scalable backend services and APIs to building intuitive, high-performance user experiences. You’ll work across the stack, turning complex AI and cybersecurity capabilities into reliable, accessible products that customers can use effectively. We’re looking for an experienced engineer with strong technical depth in both frontend and backend development-not someone who specializes primarily in one side of the stack. You’ll collaborate closely with product, design, AI researchers, security experts, and other engineers to take ideas from concept to production. If you enjoy solving complex technical challenges, care deeply about product quality, and thrive in a fast-moving startup environment, we’d love to meet you. Responsibilities Design, build, and own complex product features across the frontend and backend. Develop scalable, secure, and reliable backend services and APIs. Design and implement reliable, fault-tolerant workflows using Temporal or similar workflow orchestration technologies. Build intuitive, responsive, and high-performance user interfaces using React and TypeScript. Translate complex AI and cybersecurity data into clear, actionable product experiences. Collaborate closely with product, design, AI, security research, and engineering teams. Make thoughtful architectural decisions across the stack, balancing scalability, performance, reliability, and user experience. Maintain high standards for code quality, testing, observability, and system reliability. Identify technical challenges, improve existing systems, and contribute to the team’s engineering standards and technical direction. Take full ownership of features throughout their lifecycle-from initial design and implementation to deployment, monitoring, and continuous improvement. Requirements 5+ years of experience as a Full Stack Engineer, ideally in a startup or fast-scaling technology company. Strong hands-on experience in both frontend and backend development-a must. Strong proficiency in React, TypeScript, and modern frontend development practices. Strong backend development experience, preferably with Go or TypeScript. Experience designing and building APIs using GraphQL or REST. Solid understanding of distributed systems, system design, scalability, and performance. Experience working with databases, cloud environments, and containerized applications. Experience  with Docker, Kubernetes, AWS or GCP, and modern CI/CD practices. Experience taking complex features from concept to production with a high level of ownership. Strong product mindset and the ability to translate technical requirements into simple, effective user experiences. Excellent collaboration and communication skills. Passion for clean code, maintainable architecture, and continuous improvement. Bonus Points Experience with PostgreSQL or other relational databases. Experience with testing frameworks such as Vitest and Playwright. Familiarity with real-time applications, data visualization, or complex data-driven interfaces. Experience working with Temporal or similar workflow orchestration technologies. Experience building cybersecurity, infrastructure, DevOps, or AI-powered products. Previous experience in an early-stage startup environment. What We Offer The opportunity to build core capabilities of a cutting-edge AI-powered cybersecurity platform. Meaningful end-to-end ownership across both product and technology. A collaborative, curious, and fast-paced environment where innovation thrives. The opportunity to work closely with experienced engineers, AI researchers, and cybersecurity experts. Opportunities for professional growth and technical leadership as we scale. Competitive compensation and the excitement of being part of a fast-growing company shaping the future of autonomous cybersecurity.
