Senior Software Engineer - Go & Rust, Blockchain Infrastructure

As a Senior Software Engineer at QuickNode, you design, build, and improve the distributed systems that ingest, process, and serve blockchain data at scale across 80+ blockchain networks. You work hands-on with both Go and Rust, owning complex systems from design through production and raising the engineering bar on reliability, performance, security, and operational quality. This role reports to the Blockchain Infrastructure Engineering leadership with no direct reports at this level, though as scope grows you will mentor engineers and help set engineering standards across teams.

What you'll do

• Design, build, and optimize high-throughput, low-latency backend services, APIs, and data-processing systems in both Go and Rust for production blockchain infrastructure.
• Own production Go services and Rust components, including their architecture, interfaces, concurrency models, memory and resource efficiency, testing, observability, deployment, and operation.
• Architect distributed systems that ingest, process, validate, and serve blockchain data with strong guarantees around consistency, fault tolerance, scalability, and availability.
• Own technical work end to end, including requirements, architecture, implementation, testing, deployment, observability, incident response, and continuous improvement.
• Profile and benchmark production systems, identify bottlenecks, and improve throughput, latency, resource efficiency, resilience, and correctness under load.
• Assess security risks in blockchain and distributed-system components and design or review controls that protect transactions, data, credentials, and system integrity.
• Debug complex failures across services, databases, streaming systems, networks, and blockchain nodes, then drive durable root-cause fixes.
• Partner with Product, Infrastructure, Security, and Developer Experience teams to translate customer and protocol requirements into maintainable systems.
• Lead design and code reviews, mentor engineers, document important decisions, and establish engineering standards that improve quality across teams.

What you bring

• 8+ years of professional software engineering experience, including substantial work building and operating backend or distributed systems in high-scale production environments.
• Advanced professional proficiency in both Go and Rust, with demonstrated experience shipping and operating production software in each language. Go and Rust are both core requirements for this role, not interchangeable alternatives.
• Deep knowledge of distributed systems, algorithms and data structures, concurrency, memory safety and ownership, databases, networking, operating systems, and production software architecture.
• A track record delivering reliable, scalable systems with measurable improvements in performance, availability, correctness, or developer experience.
• Experience with blockchain infrastructure, high-throughput APIs, node or RPC infrastructure, data-streaming pipelines, or similarly demanding distributed platforms.
• Experience applying secure-design principles, threat modeling, and disciplined testing to systems where correctness and availability are critical.
• Strong written and verbal communication, sound technical judgment, and the ability to lead ambiguous, cross-team projects without constant direction.

Nice to have

• Experience with Ethereum, Solana, or other major blockchain protocols and their node, RPC, indexing, or transaction-processing architecture.
• Experience designing clean interfaces between Go services and Rust systems, libraries, or performance-sensitive components.
• Experience designing or reviewing cryptographic, wallet, signing, custody, or other security-sensitive systems.
• Experience with streaming and data infrastructure such as Kafka, queues, event-driven services, distributed databases, or large-scale observability systems.
• Demonstrated technical leadership through architecture ownership, mentorship, incident leadership, or engineering standards adopted by multiple teams.
