Senior Frontend Developer to Oplane

About this job

Your Mission & Impact As a Senior Frontend Engineer, you will step in at a crucial early stage to design, build, and own the user facing experiences of the AI security platform. The job is to turn complex data (asset graphs, threat modeling engines, and AI agent flows) into highly responsive, intuitive, and beautiful interfaces that developers actually love to use. What you will actually spend your days doing: Frontend Architecture: Drive, scale, and own the frontend applications using React and TypeScript. Bridge the Layers: Connect sleek, intuitive UIs with the Python/FastAPI backends and complex, AI driven asynchronous service layers. Lead the AI Workflow: Work actively with Claude Code and Cursor as part of your daily routine. You will guide the AI to generate modern components, while you act as the main architect, reviewer, and owner of the final codebase. Clean Code Design: Write modular, predictable frontend structures that make it easy for both human team members and AI agents to expand upon. Who You Are You are a frontend craftsman who thrives in the dynamic environment of an early stage startup, bringing the autonomy and technical ownership needed to build things from the ground up. What you bring to the table: Deep Frontend Craftsmanship: A bulletproof track record in modern frontend development, with specialized expertise in React and TypeScript. An Eye for UI/UX & Performance: A genuine interest in state management, frontend performance, and building developer centric interfaces that feel instantly responsive. The AI First Mindset: Great enthusiasm for agentic development. You look forward to leveraging AI tools to write the first drafts, focusing your brainpower on reviewing, validating, and structuring the overarching architecture. Work Authorization: Full eligibility to work in Sweden. Bonus points if you have experience with other modern frameworks (like Angular), Python based backends, GraphQL, or if you have previously built developer tools and complex SaaS dashboards. The Setup The Team: You will join a sharp, technical team of founders and engineers who move fast, collaborate closely, and are deeply passionate about technology. The Vibe: High bandwidth, real life collaboration is key here. This is a 100% onsite role at Oplane's office in central Malmö, where the team works closely to maximize execution and speed. Ready to build the future of AI security? Apply right now, or reach out to us at Qlose if you want to know more about the team and the journey ahead.
