- Optimize security performance and implement robust data isolation in distributed systems supporting multiple customers.
- Apply cryptographic solutions and monitor advances in security, including post-quantum cryptography.
- Collaborate across engineering, product, and InfoSec teams to embed security into customer features and remediate vulnerabilities.
- Use AI-driven tools to automate vulnerability triage, prioritization, and preliminary investigation.
Requirements
- Deep knowledge of Java internals, JVM memory management, concurrency models, and high-performance thread-safe, lock-free code.
- Experience building scalable, performant authorization systems with large permission sets, credential or token validation, and consistent distributed authorization decisions.

- Deep knowledge of OAuth 2.0 and SAML edge identity protocols.
- Proven experience using AI to accelerate development, debug complex systems, and optimize code.
- Ability to work autonomously and collaborate across functions, teams, projects, and codebases in a distributed environment.
- Knowledge of cipher suites, TLS handshakes, and PKI or certificate lifecycle management is preferred.
- Knowledge of cryptographic performance considerations and post-quantum cryptography is preferred.
- Experience mapping engine-level technical controls to FedRAMP Moderate or High, FIPS 140, and SOC 2 requirements is preferred.
- Hands-on experience with data-store or search-engine internals is preferred.
Benefits
