Senior Full Stack Software Engineer (f/m/d) – AI, React, Node.js & TypeScript

AI makes us faster. It doesn’t replace our human judgment. We challenge AI output, verify the results and own what we ship. We experiment fast, learn quickly and deliver with care.

Own the experience. Own the technology. Build what comes next.

Software is changing. AI agents are changing how people interact with products – and we’re building for what comes next.

Join our UI Engineering team and build production-grade products at the intersection of AI, engineering, UX and product. You’ll shape not just how our products look and work, but how people will interact with them in the future.

Be an engineer. Think like a Product Builder.

Your Mission

Own the experience. Own the technology. Build what comes next.

• Build production-grade applications with React, Next.js, TypeScript and Node.js – from UI to APIs and services.

• Design AI-native experiences: conversational UIs, agent-driven workflows and natural-language interactions.

• Use AI as an engineering multiplier. Explore, prototype, implement, debug and test faster – while staying firmly in control of architecture, quality and the final result.

• Understand the customer, the business and the problem before deciding what to build.

• Challenge assumptions, simplify complexity and turn ambiguity into products people actually use.

• Shape scalable architectures, APIs and data structures across the stack.

• Collaborate with Product, UX/UI and Engineering to make better decisions together.

• Raise the bar for testing, performance, maintainability and engineering quality.

You’re not here to turn tickets into components. You’re here to decide what should be built – and then build it.

Your Skills

• Think and work AI-native. You already use AI as part of your engineering workflow and have developed your own approach to getting from idea to production-ready code.

• Bring 5+ years of hands-on full-stack JavaScript experience and a strong track record of shipping real applications.

• Bonus: AWS, Jenkins, Grafana, Graylog, Confluence, Jira, shell scripting.

• Master React, Next.js, TypeScript and Node.js and understand modern web architectures.

• Make confident technical decisions around architecture, performance, scalability and maintainability.

• Build and test production-grade software. Hands-on experience with Jest, Vitest or Node.js testing is essential.

• Work confidently with APIs and data: REST, database design and SQL; GraphQL is a plus.

• Think beyond the code. You’re curious about customers, products and the business and use that context to make better technical decisions.

• Take ownership of outcomes, not just implementation.

• Stay curious about what’s next. Experience with AI-first interfaces, agent workflows or natural-language products is a plus.

What to expect at smartclip

• Remote-first, with meaningful time together: We work remotely most of the time, with occasional workshops, team sessions and opportunities to collaborate in person at our tech office in Berlin. We also host team events throughout the year, including our annual Company Offsite, which takes place at a different venue in Germany each year. Being willing to travel to and attend these gatherings is part of the role.

• Ownership over micromanagement: Take ownership of your work and drive your topics forward independently.

• Build > Talk: Try things early, get things wrong early, learn early.

• High standards, low ego: We give direct feedback and work together openly and respectfully.

• Keep growing: Develop your skills through hackathons, conferences and community exchange.

And of course, the benefits matter, too: 30 days of annual leave, plus December 24 and 31 off, Smart Fridays with the option of a four-day workweek, a Deutschlandticket (public transport pass) and JobRad bike leasing, sports and health benefits, mental health support, corporate discounts, access to RTL+ and much more.

Your CV is just the beginning.

What interests us more than your CV is a portfolio, a side project or a demo repo – something that shows us how you approach technical challenges and turn ideas into working solutions.
