The ideal candidate will have a strong background in systems engineering, application deployment, or cryptographic hardware management.

What you'll do:

• Deploy, configure, and maintain applications on primarily Windows-based servers, but also Linux/AIX.
• Monitor system performance and HSM health and troubleshoot issues related to application hosting environments and respond to alerts and incidents.
• Manage and maintain Hardware Security Modules (HSMs) including configuration, firmware updates, and key lifecycle operations.
• Ensure secure integration of HSMs with enterprise applications and services.
• Work with security teams to enforce cryptographic policies and compliance standards.
• Maintain detailed documentation of infrastructure configurations, deployment procedures, and HSM operations.
• Ensure compliance with internal security policies and external regulatory requirements (e.g., PCI-DSS, FIPS 140-2).
• Collaborate with cross-functional teams including Security, Networking, and Application Development and provide Tier 2/3 support for infrastructure-related incidents.

Experience you'll need to have:

• 6+ years of experience in infrastructure engineering or systems administration.
• 3+ years of experience with Linux and Windows server environments
• 3+ years of experience with application deployment tools and scripting (e.g., Bash, PowerShell, Python).
• Familiarity with virtualization (VMware, Hyper-V) and cloud platforms (AWS, Azure, Google Cloud Platform) is a plus.
• Strong understanding of networking, firewalls, and security best practices.
• Bachelor's degree in computer science, information security, or a relevant field, and/or equivalent military experience.

Experience that would be great to have:

• Experience with HSMs (e.g., Thales, SafeNet, Utimaco) and cryptographic key management
• CompTIA Security+, Network+, or Linux+
• AWS Certified SysOps Administrator or equivalent
• Certified Information Systems Security Professional (CISSP) - optional but beneficial.

How you'll work:

• All offers of employment are contingent on standard background checks. Fiserv and certain of its affiliated companies are federal, state and/or local government contractors. Should this position support a Federal Government contract, now or in the future, the successful candidate will be subject to a background check conducted by the U.S. Government to determine eligibility and suitability for federal contract employment for public trust or sensitive positions. Positions that support state and/or local contracts also may require additional background checks to determine eligibility and suitability.
• This role requires use of a computer and audio equipment.
• This role requires being on-call during non-standard and/or overnight hours on a rotational basis.
