## Description

We're hiring a Senior Software Engineer to join the Wallets, Liquidity & Bridging team within the Platform organization. This team builds and operates the wallet systems, liquidity orchestration, and bridging infrastructure that power how Coinbase moves crypto assets across 55+ blockchain protocols for millions of users. You'll design and build the distributed backend systems that construct, sign, broadcast, and reconcile on-chain transactions, helping drive the next generation of wallet infrastructure with a focus on reliability, correctness, and multi-chain scalability.

What you'll do:

 * Own the design and delivery of backend services (Go) that power wallet operations, liquidity movements, and cross-chain bridging across custodial and non-custodial flows.
 * Build and improve the distributed systems that manage transaction lifecycle, signing, broadcasting, and on-chain reconciliation across multiple blockchain protocols including Ethereum, Bitcoin, and Solana.
 * Drive reliability and observability improvements for wallet services, contributing to incident response, post-mortems, and systemic fixes that strengthen Tier-0 system availability.
 * Partner with Trading, Custody, Staking, and cross-platform teams to integrate wallet services with downstream products, defining clear contracts and resolving cross-team dependencies.
 * Execute service decomposition and architecture improvements that break down legacy systems into modular, reusable platform services other teams can build on.
 * Support engineering quality across the team through rigorous code reviews, design feedback, and sharing knowledge on architectural patterns and coding standards.
