Senior Software Engineer, Core Cryptography

As a Senior Software Engineer on the Core Cryptography team within Security, you'll act as a primary execution anchor for our most critical regulatory and cryptographic initiatives. This team is the deep-expertise center for Coinbase's Tier-0 cryptographic infrastructure, including the foundational Multi-Party Computation (MPC) engine which secures 99% of assets under custody. You'll lead the development of highly sensitive, high-availability services that directly protect customer assets and ensure global regulatory compliance.

What you'll do:

• Own the design, implementation, and end-to-end integration of critical cryptographic infrastructure, including services required for global regulatory compliance
• Lead infrastructure setup, continuous deployment, and observability strategies to proactively resolve production incidents and ensure catastrophe recovery
• Drive complex integration challenges, implementing secure and resilient infrastructure in a high-stakes, zero-trust environment
• Shape engineering quality as a technical mentor, promoting rigorous code reviews, comprehensive design documents, and best practices across the team
• Partner with cross-functional stakeholders across Security, Product, and Policy to drive flawless execution

Required Skills and Experience:

• 5+ years of experience in software engineering with demonstrated success building highly available, distributed systems
• Experience with applied cryptography, Key Management Systems (KMS), or Hardware Security Modules (HSMs), with understanding of how to safely operate within security-critical environments (Multi-Party Computation experience strongly preferred)
• Extensive programming experience in systems languages such as Golang, Java, C++, or Rust, with ability to operate in a Golang-heavy environment
• Proven track record operating Tier-0 or highly critical infrastructure where system resilience, observability, and security are absolute prerequisites, including experience configuring cloud infrastructure as code across multiple isolated environments
• Demonstrated experience managing complex projects end-to-end, removing technical blockers, navigating regulatory requirements, and mentoring team members
• Utilizes generative AI responsibly, maintaining human oversight to deliver business-ready outputs and drive measurable improvements in workflow efficiency, cost, and quality.
