You will take ownership of the frontend experience, help define how users interact with AI-powered capabilities and contribute directly to important product and technology decisions.\nOur client is particularly interested in candidates who have already contributed to the development of, or helped build, an AI-native platform.\nYou will join a small, highly technical, entrepreneurial team where autonomy, curiosity, product thinking and practical AI experience are valued.\nYour Responsibilities\nTake ownership of the frontend architecture, development and overall user experience of a growing AI-native SaaS platform.\n\nHelp design and develop intuitive interfaces combining conversational AI, interactive dashboards, AI agents and automated workflows.\n\nBuild scalable, reusable frontend frameworks and components that ensure a consistent experience across the platform.\n\nWork closely with the CTO, Product team and backend/AI engineers to translate business needs into elegant technical solutions.\n\nContribute to product discussions, challenge existing approaches and actively influence technical and UX decisions.\n\nIntegrate complex data, APIs and AI-driven functionality into seamless, user-friendly experiences.\n\nEnsure frontend performance, maintainability, reliability and code quality.\n\nActively integrate AI development tools and coding agents into your daily engineering workflow.\n\nExplore emerging technologies and continuously improve how the team designs and develops software.\n\nYour Profile\nEssential requirements\nAt least 5 years of professional frontend development experience, ideally in SaaS or other complex web applications.\n\nStrong experience with modern JavaScript/TypeScript frameworks. Angular and TypeScript experience are highly relevant, but experience with React, Vue or comparable frameworks is also valued.\n\nDemonstrable experience contributing to or building an AI-native platform, rather than simply integrating isolated AI features into an existing application.\n\nHands-on experience using AI-assisted development tools such as Claude Code, Cursor, GitHub Copilot, Codex, Gemini or similar. AI should already be a regular part of how you develop software.\n\nStrong understanding of frontend architecture, component design, API integration and modern development practices.\n\nExperience building sophisticated, intuitive user interfaces, ideally involving dashboards, analytics or data visualisation.\n\nA product-oriented mindset, with the ability to understand business objectives and translate complex functionality into simple user experiences.\n\nComfortable working independently, taking ownership and making decisions without detailed instructions.\n\nCurious, adaptable and enthusiastic about AI and emerging technologies.\n\nFluent English is mandatory, both written and spoken.\n\nYou must currently be based in the European Union and hold valid authorisation to work in your country of residence.\n\nNice to have\nExperience developing conversational interfaces, generative UI or agent-based workflows.\n\nExperience with AWS or other cloud environments.\n\nExperience with design systems, UX/UI principles and accessibility.\n\nPrevious experience as a technical lead or primary frontend owner.\n\nExperience working in startups, scale-ups or fast-moving product organisations.\n\nWhat Makes This Opportunity Different?\n100% remote working: Work from anywhere within the European Union, with occasional team gatherings.\n\nEmployee or freelancer: Our client is open to both permanent employees and independent contractors, depending on your preference.\n\nA genuinely AI-native environment: AI is at the centre of both the product strategy and the development process.\n\nReal ownership: You will have significant influence over frontend architecture, technology choices and product experience.\n\nDirect impact: Work closely with decision-makers in a small team, without unnecessary corporate hierarchy.\n\nInternational exposure: Develop a platform used by customers across the world.\n\nLong-term opportunity: Play an important role in a major product transformation with substantial room for innovation.\n\nCompetitive compensation: Salary or freelance remuneration will be discussed according to your experience, location and preferred collaboration model.\n\nInterested?\nIf you are an experienced Front-End Engineer who enjoys building products, thinks beyond code and is already actively working with AI-native technologies, we would be happy to hear from you.\nApply through Nexin for a confidential discussion about this opportunity.","description_format":"text","description_chars":5166,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Advanced
