About the role

Architect and lead development of high-throughput, low-latency streaming systems that power our core products
Drive the technical roadmap for streaming — including filtered streams, next-generation webhooks, and new capabilities that expand what developers can build on Solana
Lead system design discussions and make architectural decisions across the stack: software, hardware, and networking
Set standards for operational excellence — reliability, incident response, and system observability
Mentor and elevate engineers on the team, and drive technical consensus across engineering, product, and leadership
Partner cross-functionally with Sales, Support, and adjacent infrastructure teams to ensure streaming products meet the needs of customers at scale
Identify and solve complex, ambiguous problems that span multiple systems

8+ years of backend engineering experience with a strong track record building large-scale, production systems
Deep proficiency in Rust or an equivalent systems programming language
Performance-oriented engineering instincts — you think across the full stack: software, Linux internals, networking, and hardware
Hands-on experience with streaming systems such as Kafka, NATS, Flink, or Kinesis
Proficiency operating databases in production environments (Postgres, ClickHouse, RocksDB, or similar)
Strong operational mindset — you've owned production systems with real customers and know what it takes to keep them running reliably
Excellent communication and writing skills; you can drive technical consensus and influence without authority
High ownership and urgency — you thrive in fast-moving environments and hold yourself to an exceptional standard.
