Job summary

Chainstack is seeking a senior product engineer to build high-scale blockchain data access and processing systems. You will own problems end to end, delivering production-grade APIs, large datasets, and distributed infrastructure with a focus on performance and reliability.

You will work across databases, queues, object storage, observability, and CI/CD, using Go and/or Rust while applying AI-first development practices to accelerate delivery and documentation.

Qualifications

• 5+ years of professional software engineering experience, preferably in backend, data, infrastructure, or distributed systems roles.
• Strong production experience with Go, Rust, or comparable backend or systems languages.
• Experience owning complex engineering work end to end: requirements, design, implementation, testing, release, observability, and iteration.
• Strong understanding of distributed systems, APIs, data modeling, concurrency, queues, storage, caching, failure modes, and reliability trade-offs.
• Hands-on experience with databases and SQL, including schema design, query performance, consistency, and data quality.

Responsibilities

• Own the strategy, technical direction, delivery, and production quality of data infrastructure features from discovery to rollout.
• Understand user pain points around blockchain data access, latency, correctness, historical coverage, reliability, and operational visibility.
• Translate product and platform needs into clear specs, epics, user stories, acceptance criteria, implementation slices, and rollout plans.
• Build backend and data systems in Go and/or Rust, and work across databases, queues, object storage, observability, CI/CD, and infrastructure when needed.
• Design and improve indexing, caching, validation, benchmarking, and repair workflows for large-scale blockchain data systems.
• Use AI-first development practices to accelerate research, specification, implementation, testing, and documentation while maintaining a high verification bar.
• Collaborate with product, infrastructure, support, and customer-facing teams to gather context, make trade-offs, and close the loop after release.
• Define and analyze technical and product metrics such as latency, throughput, accuracy, freshness, coverage, error rate, reliability, and operational cost.
• Create internal tools, benchmarks, dashboards, alerts, and runbooks that make system behavior observable and easier to operate.
• Review code, specs, and designs with focus on correctness, simplicity, maintainability, performance, and production ownership.
• Conduct technical research and competitor analysis to identify opportunities for improving data products and infrastructure.
