Senior Cloud Security Engineer - InfoSec

Cloud security plays a vital role at Mercury. Behind our simple products is an infrastructure that quietly protects billions of dollars, preserves customer trust, and gives engineers the confidence to move quickly. We're looking for a Cloud Security Engineer who enjoys building those invisible supports.

We need a go-to person for designing the systems, guardrails, and automation that allow Mercury to scale without compromising security or slowing down engineering. You will work with teams across the enterprise to solve security, privacy, and compliance challenges.

As we gear up for the next stages of growth, you will:

• Help build and define cloud security posture, enable cyber resilience, and support zero trust initiatives.
• Understand Governance, Risk, and Compliance as it relates to cloud engineering.
• Work with infrastructure and engineering teams to improve the overall reliability and security of our cloud infrastructure.
• Automate cloud security controls to ensure threats, vulnerabilities, and risks are minimized.
• Shape Mercury's AWS cloud architecture around resilience, least privilege, and long-term maintainability.
• Address remote access challenges in a remote-first environment.
• Collaborate with stakeholders throughout Mercury to address security concerns in the cloud.

What we are looking for:

• 5+ years of relevant experience in cloud security, networking, information security, or other relevant fields.
• A strong desire to learn and grow with a proven track record.
• Familiarity with standard security frameworks and privacy regulations (NIST CSF, FFIEC, SOX, SOC2, GLBA, ISO27018, PCI-DSS, etc.).
• Deep problem-solving and analytical skills, with poise and the ability to act calmly and competently in high-pressure situations.
• Fundamental understanding of accepted security practices, troubleshooting issues, attack vectors, and customer support.
• Familiarity with Infrastructure as Code (IaC) tooling.
• AWS certifications are encouraged.
