Join Zip's Engineering function and put your name to solving fascinating challenges at scale in an agile, test-driven development environment. If you value good domain-driven design and enjoy delivering quality work at pace, you'll be a great fit with the squads responsible for building cloud-native software applications that serve millions of customers and process billions of dollars in payments.

As a Senior Security Engineer, you will be responsible for implementing cloud security controls that ensure the trust and reliability of our Buy Now, Pay Later (BNPL) service. Your day to day work will span analyzing an Azure cloud-native, microservices environment for security control gaps and implementing secure configurations and solutions for network, IAM and application security. You will champion cross-functional collaboration across security and engineering teams and implement globally applicable controls wherever possible.

You'll work across teams-security, engineering, infrastructure, and data-to assess risks, implement AI-specific security controls, automate secure deployment pipelines, and guide the secure adoption of new AI tools and services.

Interesting problems you'll get to solve

• Design, implement, and maintain security controls across Azure and GCP cloud infrastructure, microservices, IAM, network, and application environments.
• Leverage AI-powered tools and automation to improve vulnerability detection, risk prioritization, threat analysis, and remediation.
• Automate manual security processes and build scalable, AI-assisted security workflows.
• Collaborate with engineering and infrastructure teams to proactively identify security gaps, implement solutions, and drive risk reduction.
• Secure the adoption of AI tools and services by evaluating emerging risks and implementing appropriate safeguards.
• Monitor, triage, and remediate vulnerabilities identified through automated security scans and assessments.
• Embed security into CI/CD pipelines, infrastructure-as-code, and engineering workflows through secure-by-default practices.
• Continuously improve security capabilities through emerging technologies, intelligent automation, and modern engineering practices.

What you'll bring to the team

• BS or MS in Computer Science, Information Security, or a related technical field; additional credentials in cloud security, offensive security, or risk management are highly valued
• Security certifications strongly preferred, such as CISSP, CCSP, OSCP, GIAC, or AZ-500
• 7+ years of experience in security engineering or cloud infrastructure security, ideally in regulated or high-trust environments (e.g., fintech, healthcare, critical infrastructure)
• Hands-on experience with Azure-native security controls (e.g., Microsoft Defender for Cloud, Azure Policy, Sentinel), container security, secrets management, and SSO/IAM integrations
• Proven ability to work across disciplines and influence without authority, comfortable interfacing with Engineering, Legal, Product, and Audit functions
• Deep familiarity with threat modeling, security architecture, and risk analysis methodologies (e.g., STRIDE, MITRE ATT&CK)
• Strong written and verbal communication skills, able to articulate complex risks in business terms and influence decision-making
• Demonstrated use of AI to improve security workflows; you don't just use security tools, you build smarter ways to manage risk
