As a Senior Blockchain Engineer at Charles Schwab, you'll build and integrate the blockchain infrastructure layer that underpins Schwab's digital asset custody and tokenization platforms. This hands-on role focuses on Layer-1 blockchain integration, core blockchain infrastructure components, wallet engineering, and custody-related blockchain workflows. You'll work closely with Crypto Custody Lead Engineers and Crypto Security Engineers to ensure blockchain interactions are secure, reliable, observable, and production-ready. This role operates at the intersection of blockchain protocol mechanics and institutional custody systems.
What you'll do
- Integrate Schwab systems with existing Layer-1 blockchains such as Ethereum-based or other enterprise-relevant L1s, and evaluate where appropriate whether to contribute to building or extending Layer-1 capabilities to meet custody, scalability, or resiliency needs.
- Understand chain-level mechanics such as transaction lifecycle, finality, forks, reorgs, and event propagation, and ensure blockchain integrations are reliable under stress conditions and production loads.
- Design and build core blockchain infrastructure services, including indexers and event processors, block explorers and observability tooling, chain data services and APIs, and interoperability and cross-chain integration components.
- Ensure blockchain data pipelines are accurate, performant, and auditable, and support operational tooling required for troubleshooting, monitoring, and incident response.
- Contribute to wallet architecture and development, including blockchain-facing wallet services, transaction creation and signing workflows, submission pipelines, and integration with custody key management systems such as MPC, HSMs, and signing services.
- Ensure wallet implementations cleanly separate protocol logic, security controls, and business rules, and partner closely with custody and security engineers to validate end-to-end transaction flows.
- Share responsibility for custody-related blockchain workflows, including on-chain transaction execution, event monitoring and reconciliation, and chain-specific failure handling and recovery patterns.
- Help define safe patterns for interacting with smart contracts and token standards from custody platforms, and ensure blockchain workflows align with custody policies, approvals, and risk controls.
- Apply modern engineering practices to build reliable, testable, and observable blockchain services, and leverage GenAI and agentic AI tools to accelerate protocol analysis, code development and testing, and documentation and knowledge sharing.
What you bring
- 7+ years of professional software engineering experience.
- Hands-on experience building or integrating blockchain or distributed ledger systems.
- A strong understanding of Layer-1 blockchain protocols and transaction lifecycles.
- Experience building backend services, APIs, and infrastructure components.
- Proficiency in one or more languages such as Go, Java, Rust, Python, or similar.
- The ability to work effectively across custody, security, and platform teams.
Nice to have
- Experience with blockchain indexers, explorers, or chain analytics systems.
- Familiarity with wallet architecture and blockchain signing workflows.
- Exposure to crypto custody platforms or security-sensitive financial systems.
- Strong debugging instincts in distributed, asynchronous environments.
- Experience using AI tooling to support complex software development.
What we offer
- Competitive salary with eligibility for bonus or incentive opportunities.
- 401(k) with company match and Employee Stock Purchase Plan.
- Paid time for vacation, volunteering, and a 28-day sabbatical after every 5 years of service for eligible positions.
