Job Description

We are supporting a well-funded, next-generation Layer 1 blockchain project. The platform is purpose-built for the tokenization and on-chain circulation of real-world assets (RWA) and stablecoins, with a strong focus on institutional adoption.

The team is building infrastructure that bridges traditional Web2 institutions into Web3, expanding on-chain asset diversity, unlocking new yield opportunities, and enabling broader investor participation. Their mission is to help enterprises overcome operational, regulatory, and knowledge barriers, allowing them to deploy assets on-chain in a secure, compliant, and scalable manner. With deep RWA domain expertise and strong technical execution, the team is developing institutional-grade blockchain infrastructure and a comprehensive decentralized ecosystem designed to support large-scale, real-world asset adoption.

We are seeking a high-caliber Blockchain Developer specializing in blockchain internals to redefine the performance boundaries of the decentralized network. This role is designed for a technical visionary who thrives on solving complex challenges within execution layers, virtual machine architecture, and cross-chain connectivity.

Responsibilities

• Architect and refine high-throughput Virtual Machines (VMs), focusing on low-level tuning for parallel execution and EVM-compatible environments.

• Spearhead the development of sophisticated system-level contracts, ensuring maximum efficiency and ironclad security through expert-led audits and Gas optimization.

• Deep-dive into the source code of industry-leading protocols (such as Aptos, Solana, and Ethereum) to benchmark and implement superior consensus and execution strategies.

• Act as a primary stakeholder in architectural decisions, upholding engineering excellence through detailed code reviews and the professional development of the engineering team.

• Design and deploy robust frameworks for interoperability, ensuring the network remains agile within the broader multi-chain ecosystem.

Technical Profile

• Exceptional command of C++ and systems-level programming, with a focus on high-efficiency data structures and algorithmic complexity.

• Comprehensive understanding of VM mechanics, including stack management, state transitions, and instruction set architecture (WASM or MoveVM experience is highly valued).

• Proven ability to engineer high-stakes Solidity applications with a focus on security-first patterns and resource-efficient code.

• A track record of analyzing and contributing to major public chain infrastructures at a foundational level.

• A degree in Computer Science or a relevant quantitative field (Advanced degrees preferred).

Highly Valued Skills

• Experience building with Rust or Go for high-performance backend modules.

• Background in database engineering (e.g., RocksDB/LevelDB optimization) or multi-threaded parallel processing.
