Description

At Hazelcast, we build a high-performance, real-time data platform used in mission-critical systems across industries like finance, e-commerce and telecoms. Our platform enables applications to access and process data in milliseconds, powering use cases such as fraud detection, real-time inventory tracking and dynamic pricing.

We're looking for a Lead Software Security Engineer to take our product security program to the next level. This is a high-impact, hands-on role where you’ll guide the secure design and development of distributed systems, shape engineering and product roadmaps, and foster a security-first mindset across teams.

WHAT YOU'LL DO

Be a Security Champion

Be a trusted advisor and advocate for security across the development lifecycle, influencing architecture, design and implementation decisions.
Embed secure development practices into day-to-day workflows across engineering teams.
Own the vulnerability management lifecycle: from discovery and triage to remediation tracking and coordinated disclosure.

Build Secure Products by Design

Conduct threat models, security architecture reviews and risk assessments for new features and core platform components.
Develop secure design patterns and reusable guidance for engineers.

Drive Security Strategy & Standards

Define and evolve our secure software development standards and guidelines.
Lead the integration of security tools and automation into CI/CD pipelines.
Coordinate penetration testing and assist with remediation and root-cause analysis.

Lead with Thought and Action

Stay current on application security threats, tools and trends and share knowledge internally.
Mentor engineers and help elevate security awareness and capability across the organization.

WHAT YOU HAVE

You’re a hands-on, technically strong security engineer with deep experience securing complex systems, ideally distributed platforms. You balance a pragmatic, risk-informed mindset with a strong understanding of security principles and engineering realities.

Must-Have Experience

Proven experience in application and product security, including secure design, threat modeling and secure coding practices.
Strong knowledge of security issues in modern software stacks, such as Java, distributed systems, microservices, containers, etc.
Experience integrating security tools into development pipelines (eg. static/dynamic analysis, dependency scanning).
Hands-on experience managing and remediating software vulnerabilities.
Strong communication and collaboration skills; able to work cross-functionally with engineering, product and leadership.

Nice-to-Haves

Familiarity with JVM internals, Hazelcast or other distributed data systems.
Experience conducting or coordinating penetration tests.
Contributions to open-source security projects or involvement in the broader security community.
