Job description
Senior individual contributor role on Quicknode's Blockchain Infrastructure engineering team, designing, building and operating high-throughput distributed systems in Go and Rust that ingest, process and serve blockchain data at scale.
At a glance
- Work mode
- Remote · Lisbon, Portugal
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 we're looking for
- 8+ years of professional software engineering experience, including substantial experience 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
- Deep knowledge of distributed systems, algorithms and data structures, concurrency, memory safety and ownership, databases, networking, operating systems, and production software architecture
- A record of 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
