Are you passionate about pushing the boundaries of AI-driven development? Do you thrive on automating and outsourcing as much of the coding process to AI as possible, while still ensuring the system remains stable and robust? If so, we want to hear from you!

We are seeking a Senior Software Developer to build the core components of our next-generation cybersecurity platform that will help to protect current and future AI applications and Agents and enable AI innovation. You will collaborate closely with security researchers, analysts, product and founders to create a secure, high-performance environment that safeguards cutting-edge AI solutions.

• Who we are: We’re a fast-growing startup based in Israel, building an AI Security platform – a product that helps organizations proactively test and secure their AI Agents. Our mission is to make AI safer, and we’re starting to get traction.
• Small team, big impact: You’ll be joining a tight-knit engineering team as an early member. That means high ownership from day one – you will build significant features end-to-end and directly shape the product (and company culture) with your ideas.
• Remote-flexible & olim-friendly: We operate in English and welcome international and olim team members (no Hebrew required).
• How we work: Our style is dynamic and iterative. We move quickly to ship meaningful features, then refine based on feedback. No bureaucracy or red tape – just a focus on building something that matters. We value craftsmanship, pragmatism, and continuous learning, and we support each other to grow.
• Growth & rewards: There’s huge room to grow with us as we scale. Early team members have opportunities for rapid career progression (leadership, product ownership) as well as a meaningful equity stake in the company. You’ll share in our success as we grow

As a Full-Stack Engineer on our team, you will wear many hats (in a good way!) and tackle challenges across the stack. Specifically, you will:

• Build and own features end-to-end – from designing clean RESTful APIs and database models in our FastAPI backend, to implementing responsive and accessible UIs in our React frontend. You’ll be responsible for delivering features from concept to production.
• Design robust systems and APIs: Model data flows and define clear API contracts between services. Ensure our backend logic is well-structured, scalable, and easy to maintain. On the front end, create interfaces that are intuitive and performant.
• Collaborate on AI security workflows: Work closely with our security engineers and AI experts to integrate cutting-edge AI Security workflows into the product. You’ll help translate security testing methodologies into practical product features.
• Raise the bar on code quality: Lead by example in code reviews, enforce strong typing and clean coding practices, and continually improve our tooling and developer experience. We’re building for reliability and maintainability – you’ll help set high standards across the codebase.

• Frontend: React, TypeScript, Vite, Tailwind CSS, React Query and Axios..
• Backend: Python FastAPI (async), PostgreSQL
• Env: Docker, k8s, bitbucket CI/CD

• Develop new backend APIs
• Build slick frontend components and pages
• Integrate with AI services
• Test, monitor, and document
• Collaborate and iterate

• AI-augmented developer: You’re an early adopter of AI in your workflow. Whether it’s Claude,GitHub Copilot, ChatGPT’s codex or other tools, you use AI to automate
• Experienced in shipping products: You have a solid track record building production web applications end-to-end. (We’re thinking around 3+ years of hands-on experience, but we care more about your skills and output than an exact number.)
• routine tasks, generate code/tests, speed up debugging – and you also know when to trust your own thinking over an AI suggestion.
• Full-stack savvy: You’re strong with React and TypeScript on the front end and Python/FastAPI on the back end.
• Web fundamentals pro: Solid understanding of RESTful API design and how web apps work under the hood. You know your way around HTTP (status codes, headers, caching) and browser networking. Using tools like browser devtools or Postman to debug API calls is second nature to you.
• Security-minded: You have a good intuition for building secure software. You think about things like authentication and authorization (and least-privilege access), validate inputs, and integrate with external services in a safe way. You don’t need to be a security expert yet, but you care about not leaving doors open.
• Team player & communicator: You work well in a small team and communicate clearly. We’re an English-speaking company, so you should be comfortable working in English (no Hebrew needed). You enjoy collaborating, pair programming, and brainstorming with colleagues to solve problems.
• Adaptable and proactive: You thrive in a startup environment where things can change fast. Instead of being rattled by shifting priorities or a rewrite, you embrace them as chances to make the product better. You take initiative – if you see something broken or not optimal, you jump in and fix it. High ownership is in your nature.
• Clean architecture & patterns: Comfort with clean code architecture, repository/DAO patterns, and orchestrating complex services. If you’ve built systems with clear layering and separation of concerns, that’s a plus. We love maintainable code.

• Learn new things: You’ll be on the front lines of AI security (a cutting-edge field), gaining experience that few people in the industry have. Plus, you’ll get to work on greenfield projects and new features from scratch. We encourage mentorship, attending conferences/meetups, and continuous learning to advance your skills.
• Grow with us: We’re in rapid growth mode, which means your scope of responsibility can expand quickly. If you’re hungry to take on more, you could grow into a tech lead, own major product areas, or even build and lead a team as we scale.

• Play a key role in shaping the future of AI by protecting it
• Work alongside a diverse team of security researchers and industry experts, our founders are pioneers in AI Security, and our investors include top Engineers like ex ex-SVP of Engineering of Twitter
• Opportunity to innovate and automate in a rapidly evolving space
• Big stock compensation for first hires, professional growth, and an environment that fosters creativity and collaboration
