Senior Full Stack Software Engineer (f/m/d) – AI, React, Node.js & TypeScript
Confirmed on the employer's own hiring board on Oct 11, 2026. First seen by Alion on Oct 8, 2026.
Company Description
Remote in our day-to-day work. On-site when it matters.
We work remote by default - focused, efficient, and with full ownership. For larger features, architectural decisions, and real brainstorming sessions, we come together in Berlin - fast, hands-on, and without unnecessary meeting overhead.
We use AI to accelerate - not to replace thinking.
We design the system, steer the output, and take responsibility for what we ship.
Fast where it makes sense. Careful where it matters.
Job Description
You stopped coding. And that’s exactly why we want you.
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.
Qualifications
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.
