Role Description We need a Senior Full-Stack Developer who leans frontend – someone who makes our product look and feel as good as it works under the hood. You'll own features end-to-end, thinking through the entire user flow, edge cases, error states, and architecture before you start building. You work with high autonomy and take real ownership – we trust you to make good decisions and deliver clean solutions. - Drive frontend improvements – not just fixing bugs but proactively elevating UX and visual quality on a regular cadence. - Build and own complex full-stack features in our accounting platform. - Use Claude Code, Cursor, or similar AI engineering tools as your primary development workflow. - Adapt and extend our Python/FastAPI & Django backend where needed (CRUD-level changes and beyond). - Contribute to code quality and architecture decisions in a small senior team. Qualifications - Professional experience in software development with a proven track record of owning and delivering complex projects. - Expertise in React to build high-quality, accessible, and production-ready user interfaces. - A sharp eye for design that ensures layouts and components are implemented with pixel-perfect accuracy. - Hands-on skill with AI-assisted engineering using tools like Cursor, Claude Code, Codex, or GitHub Copilot. - The ability to work across the stack by independently navigating and extending a Python/FastAPI backend. - A systems-thinking mindset to map out full features, edge cases, and failure modes before writing any code. - Fluency in English, while any knowledge of German is a welcome bonus. Requirements - Background in agentic AI systems or LLM-powered products (nice to have). - Familiarity with B2B fintech, PostgreSQL, or German accounting standards like DATEV (nice to have). Benefits - A small team of strong, senior engineers who respect each other's time. - Real autonomy and ownership from day one. - Work that's genuinely hard and interesting – German tax law + AI agents is not a solved problem. - Competitive salary and a product that's actually used by real customers daily. - Almost no meetings – on average 95% focus time per day. - 100% Remote option, option to work abroad and no minimum required office attendance. - Fully flexible working hours apart from Daily Standup. - Berlin location preferred but remote possible.

• Design, develop, test, and deploy scalable software applications using modern engineering practices • Write and maintain comprehensive automated tests, applying approaches such as TDD/BDD and early quality validation • Integrate automated testing, security scanning, dependency checks, and quality gates into CI/CD pipelines to prevent defects and vulnerabilities early • Participate in and lead code reviews, offering constructive feedback on code quality, security, testability, and maintainability • Use cloud platforms and DevOps tools to automate infrastructure and enable reliable, efficient delivery workflows • Collaborate closely with product managers, designers, and fellow engineers to translate business needs into well‑designed technical solutions • Improve application performance, scalability, and reliability in distributed and microservices‑based systems • Mentor junior developers and contribute to a culture of continuous learning and technical excellence • Stay current with emerging technologies, tools, and best practices, and share knowledge with the team
