ServiceNow Service Mapping & Discovery Consultant

Industry: Railroad / Transportation
Openings: 2–4 Consultants
Engagement Type: Consulting

Position Overview

We are seeking 2–4 experienced ServiceNow Service Mapping & Discovery Consultants to support a large enterprise environment within the railroad/transportation industry.

The consultants will provide hands-on expertise in ServiceNow Service Mapping, Discovery, and CMDB, helping identify and map relationships across applications, infrastructure, middleware, messaging platforms, networks, containerized environments, and legacy/mainframe systems.

The ideal candidates will have strong hands-on experience configuring, executing, troubleshooting, and optimizing ServiceNow Discovery and Service Mapping in complex enterprise environments.

The technical skills outlined below may be covered collectively across the consulting team. Individual consultants are not expected to have deep expertise across every technology area.

Key Responsibilities

ServiceNow Service Mapping

• Build, configure, maintain, and troubleshoot application service maps within ServiceNow.
• Identify and map dependencies between applications, infrastructure, middleware, databases, messaging components, network services, and other supporting technologies.
• Work with application and infrastructure teams to understand application architecture and service dependencies.
• Configure and troubleshoot Service Mapping patterns and identification processes.
• Investigate incomplete, inaccurate, or failed service maps and determine root causes.
• Validate discovered relationships and ensure application service maps accurately represent the production environment.
• Support ongoing optimization and maintenance of application service maps as environments change.
• Collaborate with application owners, infrastructure teams, network teams, and other technical stakeholders to validate service relationships.

ServiceNow Discovery

• Configure and maintain ServiceNow Discovery schedules, MID Servers, credentials, and discovery patterns.
• Configure and troubleshoot discovery across complex enterprise infrastructure.
• Investigate failed discoveries, credential issues, connectivity problems, pattern failures, and incomplete discovery results.
• Analyze and resolve CMDB data-quality and relationship issues resulting from Discovery.
• Validate discovered Configuration Items (CIs), attributes, and relationships.
• Support MID Server configuration, performance, connectivity, and troubleshooting.
• Work with infrastructure and security teams to resolve network access, firewall, credential, and port requirements affecting Discovery.
• Assist with improving Discovery coverage, accuracy, reliability, and CMDB health.

Technical Capability Areas

Across the consulting team, we are seeking experience in several of the following areas:

Middleware

• Discovery of enterprise middleware and application-server technologies.
• Identification of relationships between middleware, applications, databases, servers, and supporting infrastructure.
• Experience troubleshooting middleware discovery and dependency-mapping issues.

Messaging / MQ

• Experience discovering enterprise messaging technologies, particularly IBM MQ.
• Knowledge of MQ components such as queue managers and queues.
• Ability to identify and map messaging dependencies between applications and supporting infrastructure.
• Understanding of how messaging components contribute to end-to-end application service relationships.

Network & Firewalls

• Understanding of network connectivity and access requirements supporting ServiceNow Discovery.
• Ability to troubleshoot firewall rules, connectivity issues, blocked ports, and other network restrictions affecting Discovery and Service Mapping.
• Ability to work effectively with network and cybersecurity teams to resolve Discovery connectivity issues.

Kubernetes & Containers

• Experience discovering Kubernetes clusters and containerized workloads.
• Understanding of relationships between clusters, nodes, containers/workloads, infrastructure, and application services.
• Ability to incorporate containerized environments into broader application service maps.

Mainframe

• Experience with mainframe discovery or ServiceNow integrations that bring mainframe configuration and dependency information into ServiceNow.
• Understanding of how mainframe applications and infrastructure interact with distributed enterprise systems.
• Ability to support the representation of mainframe dependencies within the CMDB and application service maps.

Required Qualifications

• Strong hands-on experience with ServiceNow Discovery and/or Service Mapping.
• Demonstrated experience building and troubleshooting application service maps.
• Hands-on experience configuring and supporting MID Servers, Discovery schedules, credentials, and Discovery patterns.
• Experience troubleshooting Discovery failures and incomplete or inaccurate discovery results.
• Strong understanding of CMDB Configuration Items, CI relationships, and dependency mapping.
• Experience investigating and resolving CMDB data-quality issues.
• Ability to analyze complex application and infrastructure relationships.
• Strong troubleshooting and root-cause-analysis skills.
• Ability to collaborate with application, infrastructure, network, security, database, middleware, and other enterprise technology teams.
• Strong written and verbal communication skills.
• Ability to document technical configurations, findings, dependencies, issues, and resolutions.

Preferred Qualifications

Experience in one or more of the following is highly desirable:

• Enterprise middleware/application servers
• IBM MQ
• Network and firewall troubleshooting
• Kubernetes and containerized environments
• Mainframe environments and integrations
• Complex hybrid infrastructure environments
• ServiceNow CMDB and CSDM
• Custom Discovery and Service Mapping patterns
• ServiceNow ITOM
• Large-scale enterprise Discovery implementations
• Transportation, railroad, logistics, or other complex operational environments

Ideal Candidate Profile

The ideal consultant is a hands-on ServiceNow ITOM practitioner who can go beyond basic configuration to investigate why Discovery or Service Mapping is not producing the expected results.

Candidates should be comfortable working across application and infrastructure layers, analyzing dependencies, troubleshooting technical issues, and collaborating with multiple technology teams to establish an accurate representation of enterprise services within ServiceNow.
