Senior Frontend Developer to Oplane

With AI tools accelerating how software is built code is being shipped faster than ever before. This acceleration comes with a major catch being architectural and security risks are accumulating just as fast.

Thats where Oplane a Malmö based tech startup comes in. They are on a mission to make secure software the default for teams building at AI speed. Instead of patching things up afterwards they embed security by design directly into the agentic workflow running automated threat modeling and delivering real time inline fixes straight into modern developer tools.

A recent $5.2 million seed round led by Seed Capital and Icebreaker vc with backing from prominent tech investors from the Neo4j and Google ecosystems is the direct driver behind expanding the engineering team right now.

Agentic coding with Claude Code and Cursor is not a weekend experiment here it is the core of how they ship software. The code is explicitly structured to optimize AI development producing clear modular architecture that both humans and AI agents can safely navigate and evolve.

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.

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 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 Oplanes office in central Malmö where the team works closely to maximize execution and speed.
