What You'll Do

Architect, develop, and maintain powerful web applications integrated with Katana’s cutting-edge Layer 2 blockchain infrastructure.
Create beautiful, responsive interfaces that simplify complex DeFi concepts for real-world users.
Develop robust backend systems and APIs that interact with smart contracts, manage blockchain data, and scale to meet user demand.
Partner closely with protocol and smart contract engineers to bring DeFi primitives (AMMs, lending, farming) to the frontend in seamless, elegant ways.
Optimize data pipelines and application performance to handle high-throughput activity and real-time blockchain data.
Implement wallet connections, authentication flows, and security best practices that users can trust.
Keep tabs on the latest developments in DeFi, Layer 2 scaling, and the web3 landscape and bring those insights back to the product.

6–8+ years of experience building full-stack web applications — from polished frontends to production-grade backends.
4+ years hands-on with blockchain protocols, smart contracts, or web3 dev tools.
Deep expertise with modern JS frameworks like React, Next.js, or Vue.js.
Comfortable with Node.js, REST APIs, microservices, and containerized stacks (Docker, Kubernetes).
Fluent in SQL (Postgres, MySQL) and NoSQL (MongoDB, Firestore).
Able to read Solidity, integrate EVM-based contracts, and understand core blockchain concepts.
Proven success in agile teams, with a passion for shipping fast and making data-driven decisions.

Nice to Have

Hands-on knowledge of intent-based bridging, solver networks, and advanced bridging layers.
Deep familiarity with liquidity protocols, yield optimization strategies, and the nuances of great DeFi UX.
Performance-tuning wizardry and a security-first mindset.
Clear communicator with a love for collaboration.
