Description

Your Opportunity

At Charles Schwab, you're empowered to make an impact on your career. Here, innovative thought meets creative problem solving, helping us "challenge the status quo" and transform the finance industry together. We believe in the importance of in-office collaboration and fully intend for the selected candidate for this role to work on site in the specified location(s).

We are hiring a Senior Engineer (58IC), Blockchain Platforms to help build and integrate the blockchain infrastructure layer that underpins Schwab's digital asset custody and tokenization platforms.

This is a hands-on engineering role focused on Layer-1 blockchain integration, core blockchain infrastructure components, wallet engineering, and custody-related blockchain workflows. The role works in close partnership with Crypto Custody Lead Engineers and Crypto Security Engineers to ensure blockchain interactions are secure, reliable, observable, and production-ready. This engineer operates at the intersection of blockchain protocol mechanics and institutional custody systems.

What This Engineer Will Do

Layer-1 Blockchain Integration & Platforms

• Integrate Schwab systems with existing Layer-1 blockchains (e.g., Ethereum-based or other enterprise-relevant L1s).
• Evaluate and, where appropriate, 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.
• Ensure blockchain integrations are reliable under stress conditions and production loads.

Blockchain Infrastructure Components

• Design and build core blockchain infrastructure services, including:
• Indexers and event processors
• Block explorers and observability tooling
• Chain data services and APIs
• Interoperability and cross-chain integration components
• Ensure blockchain data pipelines are accurate, performant, and auditable.
• Support operational tooling required for troubleshooting, monitoring, and incident response.

Wallet Architecture & Development

• Contribute to wallet architecture and development, including:
• Blockchain-facing wallet services
• Transaction creation, signing workflows, and submission pipelines
• Integration with custody key management systems (MPC, HSMs, signing services)
• Ensure wallet implementations cleanly separate protocol logic, security controls, and business rules.
• Partner closely with custody and security engineers to validate end-to-end transaction flows.

Custody-Related Blockchain Workflows

• Share responsibility for custody-related blockchain workflows, including:
• On-chain transaction execution
• Event monitoring and reconciliation
• Chain-specific failure handling and recovery patterns
• Help define safe patterns for interacting with smart contracts and token standards from custody platforms.
• Ensure blockchain workflows align with custody policies, approvals, and risk controls.

Engineering Rigor & AI-Augmented Development

• Apply modern engineering practices to build reliable, testable, and observable blockchain services.
• Leverage GenAI and agentic AI tools to accelerate:
• Protocol analysis
• Code development and testing
• Documentation and knowledge sharing
• Maintain engineering rigor-speed without sacrificing correctness or safety.

What you have

Required Qualifications

• 7+ years of professional software engineering experience.
• Hands-on experience building or integrating blockchain or distributed ledger systems.
• 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.
• Ability to work effectively across custody, security, and platform teams.

Strongly Preferred

• 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 Success Looks Like

• Blockchain integrations are predictable, observable, and resilient.
• Wallet and transaction pipelines behave correctly across normal and edge-case chain conditions.
• Custody systems interact with blockchains safely and consistently.
• Incidents related to blockchain dependencies are well understood and quickly diagnosed.
• This role establishes strong foundations for scalable digital-asset custody and tokenization platforms.

"In addition to the salary range, this role is also eligible for bonus or incentive opportunities."
