mika is revolutionizing financial management for small businesses with an AI-powered platform that combines automated accounting, proactive insights, and conversational AI. We're on a mission to make expert financial navigation and compliance accessible to every small business owner – dramatically reducing costs and bureaucratic burden. We're a small, senior team shipping fast, and every line of code we ship matters. Our stack: FastAPI & Django backend, React frontend (Material UI, react-query), PostgreSQL, AWS. We build agentic AI systems that do real accounting work. Tasks 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. That means you think 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. Concretely, you'll: - 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 – we are a senior team where everyone writes high-quality code at a high pace, and this is only possible through the use of the latest coding tools. You'll get access to all the subscriptions you need to work efficiently - 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 Requirements - 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. You have already built real things with those tools. - 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. Nice to have: - Background in agentic AI systems or LLM-powered products. - Familiarity with B2B fintech, PostgreSQL, or German accounting standards like DATEV. 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 attendence. - Fully flexible working hours apart from Daily Standup. - Berlin location preferred but remote possible.
