About Slice Global Equity

Slice Global Equity is redefining how companies manage equity, compliance, and tax across borders. We’ve raised $32M to date, including a Series A led by Insight Partners, with continued backing from TLV Partners, R-Squared Ventures, and Jibe Ventures. Slice is building an AI-native equity platform that automates global compliance in real time, across 60+ countries. We sit at the intersection of fintech, legaltech, and AI, solving one of the hardest infrastructure problems in global business. We’re headquartered in New York City, with an office in Tel Aviv. We move fast, take ownership, and think AI-first. If that sounds like you, we’d love to meet you.

The Role

We are looking for a Security Engineer to own security at Slice, reporting directly to the CTO. You’ll lead security across two core areas, Product Security and Enterprise Security, combining a systems-level view with hands-on engineering. This is an independent, high-impact role for someone who can identify risks, prioritize them, and drive solutions end-to-end in a startup environment.

Key Responsibilities

• Security Ownership: Own Slice’s overall security posture, proactively identifying threats, risks, and vulnerabilities.
• Product & Code Security: Lead improvements to product and code security in partnership with engineering teams, implementing practical security solutions that fit the company’s needs.
• Secure Development Lifecycle: Implement and advance security controls across the development lifecycle, including CI/CD pipelines and automated workflows. Improve automated detection of vulnerabilities, secrets exposed in code, and other security issues.
• Enterprise Security: Review how data is managed, how access to systems is granted, and how sensitive information is protected. Lead organizational initiatives such as access management, controls, monitoring, and MFA adoption.
• Threat Monitoring: Track emerging vulnerabilities and threats, assess their relevance to Slice, and drive action accordingly.
• Incident Response: Help prepare for and respond to security incidents, including understanding the event, containing its impact, and driving remediation.

Requirements

• Engineering Experience: 5+ years of engineering experience in software development, computer engineering, or computer science.
• Security Experience: 2+ years on a security, SecOps, or Incident Response team.
• Experience securing cloud environments.
• CI/CD: Hands-on experience with CI/CD processes, specifically GitHub Actions.
• Risk to Solution: Ability to understand systems and development processes, identify risks, and translate them into technical and process solutions.
• Ownership: Ability to independently drive work from identifying the need through implementing the solution, with initiative, a systems mindset, and the ability to drive change across the organization.

Nice to Have

• Experience in cyber incident response and investigation.
• Familiarity with additional CI/CD systems.
• Experience at a high-growth company or in a startup environment.
• Experience with Open telemetry and observability tools.

Why Join Slice?

• End-to-end ownership: Own security across our product, code, and organization.
• Technical depth: Work across product security, infrastructure, and enterprise systems.
• Collaboration: Partner with top engineers and designers in Tel Aviv.
• Team culture: Collaborative, ambitious, and impact-driven.
