• Experience working collaboratively within an engineering team.
• Exposure to Go (Golang) or similar backend languages.
• Familiarity with Web3, distributed systems, or infrastructure-heavy platforms.
• Background that includes both larger, established engineering organizations and smaller or fast-moving teams.

Responsibilities

• Own component-level (and larger) engineering work from design through production release.
• Deliver key CRE features that enable services to operate across multiple decentralized oracle network (DON) environments.
• Build and maintain systems that prioritize reliability, correctness, and scalability under real-world usage.
• Collaborate with teammates and cross-functional partners to ensure solutions are technically sound and product-aligned.
