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.

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.

• 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
