Assist in optimizing transaction pipelines for speed and reliability under senior guidance.
Contribute to building secure, production-grade systems that meet performance requirements.
Help maintain high-availability infrastructure across cloud and distributed environments.
Learn and apply best practices for observability, reliability, and secure operations.
What Success Looks Like
Reliable contribution to a stable mainnet with consistent uptime and availability.
Active participation in improving exchange performance and latency.
Quickly ramping up on internal tooling and workflows - first meaningful contribution within the first month.
Growing comfort with high-performance benchmarking and infrastructure tuning.
Positive collaboration with the team and consistent delivery on assigned tasks.
Must-Have
Experience, with some exposure to infrastructure or distributed systems.
Working knowledge of Rust, Go, or another systems language.
Basic understanding of distributed systems concepts (consensus, fault tolerance, latency).
Hands-on experience with Docker; familiarity with Kubernetes is a plus.
Exposure to observability tools such as Prometheus, Grafana, or similar.
