• Developing scalable APIs, indexing services, and data pipelines to support trading data access
• Building and maintaining infrastructure for trading
• Writing clean, performant, well-tested, and production-ready code
• Collaborating closely with protocol engineers, infrastructure teams, and product engineers

What you bring:

• 5+ years of experience building and shipping scalable backend systems
• Strong experience building backend systems in languages such as Rust, Go, C++, Java, Python, or similar
• Deep understanding of systems programming concepts
• Strong understanding of distributed systems, databases, and API design
• Strong problem-solving skills and the ability to work autonomously in a fast-paced environment
• Experience with blockchain infrastructure, indexing, or node operations (a plus)
• Web3 experience or familiarity (a plus)
