We are currently looking for a strong Full-Stack Developer-AI-First SaaS Engineer
About the project: Join a fast-growing AI-first product company building a B2B SaaS platform that helps organizations simplify security, compliance, and AI governance. The platform automates processes that traditionally require significant manual work — from evidence collection and monitoring to audit preparation and certification workflows. You’ll join a lean, highly collaborative international engineering team distributed across Europe, Israel, and South Africa.
About the role: We’re looking for a Senior Full-Stack Developer who is comfortable working across both frontend and backend and enjoys taking ownership of features from idea to production. This is an AI-first engineering environment. AI is used both as part of the product and as a standard part of the development workflow. You’ll use AI-assisted development tools to accelerate implementation, debugging, testing, and refactoring while maintaining strong engineering judgment and the ability to write and understand code independently. You’ll work closely with Engineering and Product on system design, architecture, and feature development, with a particular focus on building high-quality React experiences while contributing confidently to the backend.
What you’ll do: * Build and deliver full-stack features end to end using React, TypeScript, and Node.js. * Develop intuitive, performant, and scalable frontend experiences for a complex B2B SaaS product. * Implement backend services, APIs, business logic, and third-party integrations. * Develop and integrate AI-powered product features. * Participate in system design and architectural decisions. * Use AI-assisted development tools such as Claude Code or similar as part of your everyday workflow. * Review, debug, test, and improve AI-generated code while maintaining ownership of the implementation. * Take responsibility for the CI/CD and DevOps aspects of the features you build. * Work closely with Engineering and Product to define requirements and technical solutions. * Participate in Agile ceremonies and collaborate with a distributed international team. * Communicate technical decisions clearly and confidently in English.
What we’re looking for: * 5+ years of professional software development experience. * Strong experience with Node.js and React. * Solid knowledge of TypeScript. * Experience building and integrating REST APIs. * Strong full-stack capabilities and the ability to work comfortably across frontend and backend. * Experience developing and shipping AI-powered features in a production environment. * Practical experience using AI coding assistants such as Claude Code, Cursor, GitHub Copilot, or similar tools. * Good understanding of software engineering fundamentals, testing, debugging, and code quality. * Experience with cloud environments and CI/CD. * Understanding of scalable and distributed systems. * English — C1 or higher, with strong verbal and written communication skills and the ability to confidently discuss technical and architectural topics in real time. * Experience working in a product or SaaS environment.
Nice to have: * Experience with Python. * Experience with AWS or another major cloud provider. * Familiarity with Docker, Kubernetes, or microservices. * Experience with LangChain, LangGraph, or similar AI/agent frameworks. * Experience building high-scale SaaS products with complex, polished UIs. * Background in security, compliance, GRC, or developer tools. * Experience taking ownership of the frontend area within a full-stack team. * Experience with automated testing and QA practices.
What we offer: — Flexible Work Environment: Opportunity to work remotely. — 1:1 English Classes: Individual English language training. — Premium Medical Insurance: Comprehensive health insurance. — Great Team: Supportive, collaborative, and dynamic international team. — Equipment Provided: All necessary equipment supplied. — Accounting Support: Full accounting assistance in Ukraine and Poland. — Paid Time Off: 18 days of annual vacation and 7 days of sick leave without a doctor’s note. — Flexible Payment System: Convenient payment solution with multiple withdrawal options.
