Responsibilities
- Design and deliver major security components within the Elasticsearch core engine from architecture through production.
- Develop scalable security models for authentication, authorization, identity management, cryptography, and tenant isolation.
- Optimize security performance in high-concurrency distributed systems and shared infrastructure.
- Apply cryptographic solutions and maintain robust data isolation across disparate customers.
- Collaborate with engineering, product, and InfoSec teams to embed security into customer features and identify, assess, 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 or lock-free code.
- Experience building scalable, performant authorization systems with large permission sets, credential or token validation, and consistent distributed authorization decisions.
- Strong understanding of distributed systems security, mutual trust, zero-trust transport, partition tolerance, and cluster state propagation.
- Deep knowledge of OAuth 2.0 and SAML edge identity protocols.
- Proven experience using AI to accelerate development, debug systems, and optimize code.
- Ability to collaborate across functions, move between projects or codebases, and work autonomously in a distributed team.
- Preferred experience with cipher suites, TLS handshakes, PKI and certificate lifecycle management, post-quantum cryptography, FedRAMP, FIPS 140, SOC 2, and data-store or search-engine internals.
Benefits
- Distributed work environment with flexible locations and schedules for many roles.
- Health coverage for employees and families in many locations.
- Generous vacation days and at least 16 weeks of parental leave.
- Elastic matches up to $2,000 or local equivalent for financial donations and service.
