Senior Software Engineer - Go & Rust, Blockchain Infrastructure

Quicknode operates cloud infrastructure serving the blockchain ecosystem. The company powers billions of daily requests across 80+ blockchain networks, providing institutional-grade services like Core RPC APIs, Streams, Webhooks, and Clusters. Backed by Tiger Global, Y Combinator, SoftBank, and other top-tier investors, Quicknode maintains a team of over 110 engineers split between remote work and offices in Fort Lauderdale and Lisbon.

You'll join the Build team as a Senior Software Engineer focused on the distributed systems that ingest, process, and serve blockchain data at massive scale. This is a hands-on role combining individual contribution with technical leadership—no direct reports, but plenty of opportunity to mentor, set standards, and grow toward Staff or Principal Engineer positions.

What you'll do

• Design and build high-throughput, low-latency backend services and data-processing systems in both Go and Rust that power production blockchain infrastructure.
• Own complete ownership of production systems from architecture and implementation through testing, deployment, observability, and incident response.
• Architect distributed systems handling blockchain data ingestion, processing, validation, and serving with strong consistency, fault tolerance, and availability guarantees.
• Profile production systems to identify bottlenecks, then improve throughput, latency, resource efficiency, and resilience under load.
• Assess security risks in blockchain and distributed components, design controls protecting transactions and data integrity.
• Debug complex failures across services, databases, streaming systems, and blockchain nodes, driving durable fixes.
• Lead design and code reviews, mentor other engineers, document architectural decisions, and establish engineering standards adopted across teams.

What you'll bring

• 8+ years shipping and operating backend or distributed systems in high-scale production environments.
• Advanced proficiency in both Go and Rust—both are required, not interchangeable. You need demonstrated experience running production software in each language.
• Deep knowledge of distributed systems, algorithms, concurrency models, memory safety, databases, networking, operating systems, and production architecture.
• Track record delivering reliable, scalable systems with measurable improvements in performance, availability, or developer experience.
• Experience with blockchain infrastructure, high-throughput APIs, RPC infrastructure, or data-streaming pipelines.
• Applied expertise in secure design, threat modeling, and testing for systems where correctness is critical.
• Strong communication, sound judgment, and ability to lead cross-team projects independently.

Nice to have

• Experience with Ethereum, Solana, or other major blockchain protocols and their node or RPC architecture.
• Experience designing clean interfaces between Go services and Rust components.
• Familiarity with cryptographic, wallet, or custody systems.
• Experience with Kafka, event-driven services, distributed databases, or large-scale observability.
• Demonstrated technical leadership through architecture ownership or incident leadership.

What We Offer

• Competitive compensation with individualized discussion based on your requirements and experience.
• Full-time remote position based in the United States.
• Benefits designed to be employee-centric across all operating locations.
