About the role

Principal Architect providing enterprise-wide architectural leadership in low-latency, high-availability platforms at Fiserv. Influencing architectural decisions and driving improvements across multiple teams.

Responsibilities

Provide enterprise-wide architectural leadership for infrastructure and platform services supporting low-latency, high-throughput, and highly resilient systems.
Define and evolve reference architectures, architectural principles, and design standards used across multiple teams and technology domains.
Lead the design of complex systems end-to-end—from bare metal and operating systems through networking, storage, and distributed platform services.
Drive architectural decisions that materially improve reliability, resiliency, observability, and operability at scale.
Influence standards for business continuity, disaster recovery, security controls, vulnerability management, and governance.
Architect platforms that enable and integrate with IT service management (ITSM), configuration management databases (CMDBs), lifecycle management, and operational governance frameworks.
Evaluate emerging technologies and guide responsible adoption, including streaming data platforms, modern data architectures, and machine-learning-enabled systems.
Act as a technical mentor and thought leader, providing architecture reviews, design guidance, and hands-on problem solving for the organization’s most complex challenges.

15+ years of deep technical experience in infrastructure engineering, platform engineering, systems architecture, or enterprise architecture roles.
Proven track record of enterprise-scale impact, designing and influencing highly available, low-latency, distributed systems used across multiple teams or business units.
Deep understanding of Linux system internals, networking, and infrastructure platforms (data center, cloud, or hybrid).
Experience across a wide range of technologies including distributed systems, databases (relational and non-relational), and data or messaging platforms.
Demonstrated ability to design systems with strong security, auditability, governance, and lifecycle management requirements.
Hands-on experience with CI/CD automation and zero-downtime or rolling deployment architectures.
Hands-on systems programming experience required, with the ability to design, build, debug, and reason about complex systems through code when needed. This includes deep experience in one or more languages such as Python, C/C++, Java, Erlang, Elixir, Prolog, R, Julia, or similar, with an emphasis on architectural correctness, performance, and reliability rather than routine feature development.
Ability to communicate and influence effectively across engineering, operations, security, and executive stakeholders.
