Senior Software Engineer - Cross-Chain Intent-Driven DEX Headquarters: Gibraltar Remote | Full-time Compensation:  $140K - $160K Our client is a pioneering technology firm developing advanced solutions to enable seamless cross-chain interactions within an automated, intent-driven world. By connecting AI, services, and financial applications, the organization designs intent-driven liquidity layers where smart contracts, AI agents, and blockchain networks synchronize in real-time. With deep expertise in AI, cryptography, and decentralized finance (DeFi), the team is redefining how intelligent agents interact across global networks. The organization is seeking a Senior Software Engineer to contribute to the improvement and maintenance of innovative decentralized applications (DApps) within the NEAR ecosystem. This role is ideal for an individual who thrives in a fast-paced startup environment and is motivated by the prospect of building ground-up solutions at an early project stage. The position focuses on developing a high-performance frontend and an SDK for a cross-chain decentralized exchange (DEX) utilizing multi-party computation, chain signatures, secure enclaves, and intent-based architecture. A primary goal of this role is to bridge the gaps between EVM and non-EVM chains, requiring a profound understanding of Web3 technologies. Key Responsibilities - User Experience Excellence: Ensure that precise financial instruments are intuitive, easy to use, and clearly understood by the end user. - Performance Engineering: Optimize every millisecond of user interactions to provide a "blazing-fast" experience. - Observability: Implement deep tracing and observability across user flows to monitor system health and transaction success. - Developer Enablement: Design and build the best possible SDK for other DApps to integrate and utilize. - State Management: Design, test, and implement highly resilient state machines for managing Request for Quote (RFQ) processes. - Full-Lifecycle Engineering: Bridge the gap between business requirements and technical implementation, defining both the aesthetic and functional aspects of the application.
