Senior Software Engineer, CCIP

Chainlink Labs is the industry-standard oracle platform that powers decentralized finance (DeFi) and enables secure cross-chain transactions. The Senior Software Engineer role focuses on designing and operating core services for the CCIP protocol, enhancing reliability, performance, and security of interoperability infrastructure.

Responsibilities:

• Deliver backend services that coordinate fast, fault-tolerant cross-chain transactions across multiple blockchain ecosystems
• Improve system reliability and resilience under adversarial conditions to strengthen protocol trust and uptime
• Reduce transaction processing latency through optimizations in RPC usage and system performance
• Enable seamless integration across EVM and non-EVM ecosystems, accelerating adoption of CCIP
• Increase throughput to scale CCIP to support thousands of concurrent cross-chain transfers without degradation or backlog
• Build internal systems that allow rapid debugging, replay, and resolution of failed transactions

Requirements:

• Demonstrated strong backend engineering experience using Go, Rust, or TypeScript in production systems
• Proven track record contributing to or building within crypto-native projects
• Designed systems with security and reliability as foundational principles, particularly in adversarial or distributed environments
• Built or operated backend systems that prioritize fault tolerance, consistency, and high availability
• Demonstrated knowledge of DeFi protocols and ecosystem dynamics
• Experience working with cloud infrastructure and containerized systems in production environments
• Hands-on experience interacting with blockchain bridges or interoperability protocols
• Understanding of security risks specific to cross-chain or bridge-based architectures
• Familiarity working with non-EVM ecosystems such as Solana, Aptos, or similar
• Experience debugging and operating distributed systems at scale
