Job description

Senior Front-End Engineer – AI-Native SaaS Platform

Fully Remote (EU) | Permanent Employment or Freelance | English Required

For an innovative European technology company undergoing an exciting transformation, Nexin is exclusively recruiting a Senior Front-End Engineer to help shape the future of an AI-native SaaS platform.

Our client is an established software company with an international customer base, currently transforming its existing analytics solution into a next-generation, AI-native platform.

This is not a traditional frontend development role where you simply implement predefined designs or specifications. 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.

Our clientis particularly interested in candidates who have already contributed to the development of, or helped build, an AI-native platform.

You will join a small, highly technical, entrepreneurial team where autonomy, curiosity, product thinking and practical AI experience are valued.

Your Responsibilities

• Take ownership of the frontend architecture, development and overall user experience of a growing AI-native SaaS platform.

• Help design and develop intuitive interfaces combining conversational AI, interactive dashboards, AI agents and automated workflows.

• Build scalable, reusable frontend frameworks and components that ensure a consistent experience across the platform.

• Work closely with the CTO, Product team and backend/AI engineers to translate business needs into elegant technical solutions.

• Contribute to product discussions, challenge existing approaches and actively influence technical and UX decisions.

• Integrate complex data, APIs and AI-driven functionality into seamless, user-friendly experiences.

• Ensure frontend performance, maintainability, reliability and code quality.

• Actively integrate AI development tools and coding agents into your daily engineering workflow.

• Explore emerging technologies and continuously improve how the team designs and develops software.

Your Profile

Essential requirements

• At least 5 years of professional frontend development experience, ideally in SaaS or other complex web applications.

• Strong experience with modern JavaScript/TypeScript frameworks. Angular and TypeScript experience are highly relevant, but experience with React, Vue or comparable frameworks is also valued.

• Demonstrable experience contributing to or building an AI-native platform, rather than simply integrating isolated AI features into an existing application.

• Hands-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.

• Strong understanding of frontend architecture, component design, API integration and modern development practices.

• Experience building sophisticated, intuitive user interfaces, ideally involving dashboards, analytics or data visualisation.

• A product-oriented mindset, with the ability to understand business objectives and translate complex functionality into simple user experiences.

• Comfortable working independently, taking ownership and making decisions without detailed instructions.

• Curious, adaptable and enthusiastic about AI and emerging technologies.

• Fluent English is mandatory, both written and spoken.

• You must currently be based in the European Union and hold valid authorisation to work in your country of residence.

Nice to have

• Experience developing conversational interfaces, generative UI or agent-based workflows.

• Experience with AWS or other cloud environments.

• Experience with design systems, UX/UI principles and accessibility.

• Previous experience as a technical lead or primary frontend owner.

• Experience working in startups, scale-ups or fast-moving product organisations.

What Makes This Opportunity Different?

• 100% remote working: Work from anywhere within the European Union, with occasional team gatherings.

• Employee or freelancer: Our client is open to both permanent employees and independent contractors, depending on your preference.

• A genuinely AI-native environment: AI is at the centre of both the product strategy and the development process.

• Real ownership: You will have significant influence over frontend architecture, technology choices and product experience.

• Direct impact: Work closely with decision-makers in a small team, without unnecessary corporate hierarchy.

• International exposure: Develop a platform used by customers across the world.

• Long-term opportunity: Play an important role in a major product transformation with substantial room for innovation.

• Competitive compensation: Salary or freelance remuneration will be discussed according to your experience, location and preferred collaboration model.

Interested?

If 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.
