Berlin • Cybersecurity & AI Startup • Recently FundedA newly funded cybersecurity startup in Berlin is looking for a Frontend Engineer(React) to join as a founding team member and help design the core security, identity, and enforcement foundations of a next-generation AI-powered security risk management platform.We are an early-stage startup founded by experienced cybersecurity leaders with backgrounds in Israeli Intelligence units. We are looking for a hands-on Founding Frontend Engineer(React) for a hybrid role based in central of Berlin. If you are passionate about cybersecurity and AI tech, thrive in fast-paced startup environments, and enjoy building complex platforms from the ground up, this is an opportunity to make a real impact.We’re building a next-generation cyber risk platform that helps enterprises understand, measure, and reduce identity risk at scale. Our goal is to turn complex identity and security data into clear, actionable risk insights that CISOs and CTOs can trust. You will work from scratch on core platform components from day one, shaping how modern enterprises manage and reason about risk using cloud-native systems and AI-driven analysis and automated enforcement through AI Agents.Key ResponsibilitiesDevelop and maintain frontend applications using React and TypescriptDesign and build the frontend architecture of the platform from scratchDevelop high-quality, performant, and secure user interfaces for a complex cybersecurity and risk management productBuild dashboards and visualizations that turn complex identity and security data into clear, actionable insightsCollaborate closely with backend, data, and AI engineers to define APIs, data contracts, and user flowsOwn frontend state management, performance optimization, and UI architecture decisionsImplement authentication, authorization, and role-based access patterns on the frontendEnsure high standards for UX, accessibility, and responsiveness across devicesEstablish frontend engineering best practices, testing, and code quality standardsRapidly prototype new features and iterate based on user feedbackContribute to product decisions by balancing usability, security, and technical constraintsDebug and resolve complex frontend issues across browsers and environmentsBuild whole platform from scratchMust have skills10+ years of Software Development experience7+ years of React, Redux and Typescript experienceExperience building complex, data-heavy web applications or dashboardsStrong understanding of frontend architecture, component design, and state managementExperience integrating frontend applications with REST and/or GraphQL APIsHands-on experience with modern frontend tooling (Tailwind, Webpack, npm/yarn)Strong knowledge of browser fundamentals, performance optimization, and security best practicesExperience implementing authentication flows (OAuth/OIDC, JWT-based sessions)Ability to write clean, maintainable, and well-tested codeKnowledge of Tailwind CSS and WebpackExperience with building frontend for AI agentsExperience with Coding CoPilots(Claude Code, GitHub Copilot, AWS Whisperer, Codex, etc.)Experience supporting production SaaS platformsAbility to build things from scratch at early stage startupHigh ownership mentality, startup mindset, and ability to move quicklyExperience in startup or scale-up environmentsProven ability to design and ship complex distributed systemsLow ego, high commitment, and a true tech startup mentalityStrong problem-solving skills and ability to work in a collaborative environmentExcellent English communication skillsNice-to-have requirementsFamiliarity with data visualization libraries (ECharts, Recharts, Chart.js, or D3.js)Familiarity with design systems and component librariesExperience with frontend testing frameworks (Cypress, Jest, etc.)Exposure to cybersecurity, identity, or enterprise SaaS productsExperience with performance monitoring tools (Sentry, OpenTelemetry)Knowledge of RBAC/ABAC or fine-grained access modelsExperience designing permission models, identity graphs, or access control frameworksKnowledge of Zero Trust principles, least privilege, and continuous verificationAbility to design secure distributed systems and define clear service boundariesHands-on ability to build PoCs and technically validate implementation decisionsExperience with Security related to AI/LLM systems, agent logic, or willingness to learn fastPrevious experience in cybersecurity, identity startupsYou are a fan of rock or metal musicExcellent German communication skillsBenefitsFounding Team Member Equity — ESOPs in a cybersecurity companyCompetitive Compensation — salary aligned with market, flexible early-stage arrangements possibleFounding Team Member Status — shape the company from day one and own critical frontend technical decisionsFresh Funding Secured — immediate runway to build, hire, and execute fastSecurity Contribution — contribute to frontend architecture across identity, AI agents, and enforcementHigh Autonomy — freedom to design and build without corporate overheadWork with a Technical CEO and CPTO — fast iteration, strong alignment, clear directionCutting-Edge Domain — identity security, SaaS-to-SaaS access, AI agent governanceMassive Learning Curve — quickly gain depth in cybersecurity, identity, and AI systemsFast Career Path — opportunity evolve into leadership as we scale the engineering teamBerlin Location — top-tier tech environment with strong cybersecurity and AI ecosystemsDirect Impact — your architecture and code become the foundation of the entire platformBest Equipment and Tools - High quality equipment and modern tools to help you do your best work from day oneTeam Offsites - Regular team offsites designed to build strong connections, alignment, and shared momentumFind Jobs in Germany on Arbeitnow
