Event Management ServiceNow ITOM Developer

Booz Allen Hamilton•McLean, VA

9d•Remote

About The Position

This is a hands-on development role where you will combine development with big picture thinking to make an impact on the services people rely on every day. You will own the layer where monitoring signal becomes action. Your customers will trust you not only to build and tune Event Management — connectors, event rules, correlation and grouping logic, and alert-to-incident automation — but to evolve it, moving event classes from human-handled to fully automated one at a time, each with the verification, rollback, and evidence to demonstrate it is safe. On our team, you'll broaden into ITOM, CSDM, and agentic operations. You'll write and review code, and what you build will act on production systems.

Requirements

5+ years of experience in ServiceNow development, including workflows, forms, UI policies, business rules, and integrations
Experience working in Scrum or SAFe
Experience with JavaScript, the Glide API, and Python or a language for data transformation and automation, and with event management concepts including deduplication, correlation, alert grouping, and threshold design
Experience integrating monitoring or third-party systems using REST or SOAP APIs, including MID Server configuration and troubleshooting, and knowledge of CMDB structure and CSDM
Experience building automation with explicit safety design, including approvals, verification, and rollback
Ability to run root cause analysis on detection gaps and false positives, tracing a bad alert from source event through rule evaluation to the record it created
Bachelor's degree in a CS or Information Systems field
ServiceNow Certified System Administrator (CSA) certification
U.S. citizenship is required

Responsibilities

Build and tune ServiceNow Event Management, including connectors, event rules, correlation and grouping logic, aggregation, and alert-to-incident automation.
Normalize severity and event fields across monitoring sources so that every alert arrives on one consistent, ITIL-aligned scale.
Engineer entity-to-CI binding accuracy, partnering with CMDB owners on identification, reconciliation, and CSDM alignment where binding breaks.
Develop automated and agentic remediation with bounded blast radius, approval gates, verification that the service recovered, rollback, and a complete evidence trail.
Integrate monitoring platforms with ServiceNow through REST, IntegrationHub, and Flow Designer, and keep those integrations stable through platform upgrades.
Move event classes from human-handled to automated one at a time, and prove each one with evidence that holds up under audit.
