Product Engineer

About the Role You will own problems end to end, from understanding user needs to building, shipping, and improving production systems. You will design and implement performance-sensitive APIs and large-scale data systems using Go or Rust, and work across databases, queues, object storage, observability, CI/CD, and infrastructure. You will translate product needs into specs and rollout plans, design indexing, caching, validation, benchmarking, and repair workflows, create tools, dashboards, alerts, and runbooks, and measure metrics like latency, throughput, accuracy, and reliability. You will use AI-first development practices to accelerate research, specification, implementation, testing, and documentation while maintaining a high verification bar, and collaborate with product, infrastructure, support, and customer-facing teams to gather context and iterate after release.

Requirements 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 Experience with performance-sensitive systems, including benchmarking, profiling, load testing, bottleneck analysis, and capacity planning Comfortable working with cloud-native infrastructure, CI/CD, containers, observability platforms, and infrastructure-as-code concepts Practical experience using AI coding assistants or agentic development workflows for non-trivial engineering tasks Ability to write high-quality specs, technical proposals, acceptance criteria, runbooks, and concise engineering updates Strong product sense with ability to connect technical work to user impact and measurable outcomes Excellent written and verbal English

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
