Software Engineer - Crypto Data Foundations

The Blockchain Data Platform team within the Platform organization builds an ultra-low-latency indexing platform that ingests, normalizes, and serves data across major blockchains, powering teams across Coinbase and external developers via the Coinbase Developer Platform. We're a small, high-impact, AI-native team taking a platform-first approach, shipping the primitives, SDKs, and tooling that make blockchain indexing as easy as building on a managed database. You'll build and operate the distributed systems at the core of this platform, owning services end-to-end from design through production.

What you'll do:

• Build and operate distributed systems for real-time blockchain data ingestion, indexing, and query, owning services end-to-end from design docs and data modeling through code, rollout, and observability.
• Own delivery of key initiatives such as new chain integrations, migrations, and backfills, driving improvements to latency, reliability, and cost.
• Partner with product and platform teams to define data contracts and contribute to SDKs and primitives that drive adoption across Coinbase and external developers.
• Execute architecture and performance improvements across the indexing stack, applying strong systems design fundamentals around partitioning, consistency, stream processing, and storage boundaries.
• Support engineering quality across the team through code reviews, testing rigor, and leveraging AI tools to ship faster and reduce operational burden.

Required Skills and Experience:

• 2+ years of software engineering experience building and operating distributed or data systems in production.
• Solid systems design fundamentals including partitioning, consistency/availability tradeoffs, stream processing, and storage/compute boundaries.
• Proficiency in a backend language such as Go and/or Python, with familiarity across technologies like Kafka, gRPC, Redis, S3, ClickHouse, or MongoDB.
• Demonstrated ability to turn ambiguous problems into clear designs and shipped solutions with measurable impact.
• Blockchain or crypto data experience is a plus, including familiarity with chain data structures, finality, reorgs, RPC nodes, or wallets.
• Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality.
