Senior Frontend Developer Needed — Next.js / TypeScript for large existing project Job

We need a Senior Frontend Developer to join our team working on Valkra, an AI-powered smart contract security and auditing platform.
Valkra is an existing project that combines AI/LLM analysis, automated security tools, vulnerability detection and real-time audit processing across multiple blockchain ecosystems.
The frontend is built with Next.js, TypeScript, React and Tailwind CSS and is already substantially developed. We’re now looking for a senior developer to help complete, improve and prepare the frontend for production.
What you'll do
· Develop and improve the existing Next.js/TypeScript frontend
· Build and refine audit dashboards, findings, reports and project management interfaces
· Integrate frontend features with Rust backend APIs and WebSockets
· Fix bugs and improve performance, usability and reliability
· Work closely with backend and other developers to deliver features
Requirements
· Strong professional experience with Next.js / React / TypeScript
· Experience with REST APIs and WebSockets
· Experience working with existing production codebases
· Strong debugging and problem-solving skills
· Good Git and collaborative development experience
Experience with AI platforms, Web3/blockchain, security applications or complex dashboards is a plus.
TeamWork
You’ll be working as part of a small team of 3–4 senior developers with separate backend/security responsibilities. Strong communication and teamwork are important, as frontend development will need to closely integrate with the backend and analysis systems.
This is intended to be a long-term collaboration, not a one-off task.
When applying, please include your relevant experience, portfolio/GitHub, availability and hourly rate and briefly describe a relevant frontend project you have worked on.
