Matthew S

AVP, Engineering Manager

Jan 2015 - Oct 2021 • 6 yrs 9 mos

Transitioning into engineering leadership, I led a cross-functional team of 15 engineers managing identity and access governance across more than 6,500 production Unix and Linux servers. In this role, I bridged technical architecture and operational execution by authoring interface contracts, container and database evaluation white papers, and definitive SEV1 post-mortems for complex disk I/O bottlenecks and race conditions. I also documented internal REST APIs and data schemas for internal Rails and Python tooling—cutting compliance review cycles by 75%—while introducing Architecture Decision Records (ADRs) and operational handbooks to establish standard engineering practices across our distributed pods.

Senior Systems Engineer

Mar 2009 - Dec 2015 • 6 yrs 9 mos

During my initial tenure at Wells Fargo, I focused on systems engineering, infrastructure reliability, and deep technical documentation across enterprise RHEL, CentOS, and Solaris environments. I developed operational automation using Ansible to standardize OS hardening and patch cycles, and heavily tuned Linux kernel parameters (sysctl) to stabilize socket buffers and page cache behavior under heavy database loads. Beyond day-to-day administration, I authored the firm’s disaster recovery runbooks, multi-node failover protocols, and Tier-3 on-call incident workflows, while documenting CLI reference guides and integration specs for Privileged Access Management (PAM) and BoKS security platforms to slash MTTR during major outages.
