From the original posting

Medieval cathedral builders understood that the flying buttress wasn't the building. Visitors came to admire the stained glass and soaring ceilings, not the stone supports outside. But without those supports, none of the beauty could stand.

Cloud security plays a similar role at Mercury. Our customers come for products that feel remarkably simple. Behind that simplicity 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.

Protecting our customers’ security and privacy is a top priority. We're all about using the latest technology to do things smarter. That's why we need a Cloud Security Engineer. This person will be our go-to for designing the systems, guardrails, and automation that allow Mercury to scale without compromising security or slowing down engineering. The ideal candidate should be ready and willing to come up with innovative solutions leveraging the newest technologies to address the unique problems they encounter. We work with teams across the enterprise to solve security, privacy, and compliance challenges so be ready to collaborate.

Come be a part of helping us stay safe and maintain trust with our customers!

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

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

The ideal candidate should have:

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