Senior Application Developer, ServiceNow (100%)

Your Mission

Take end-to-end ownership of our ServiceNow platform customization and ongoing improvement, with a strong focus on ITSM and ITOM. You will partner closely with IT and HR stakeholders to deliver scalable, upgrade-safe solutions that align with ServiceNow best practices—knowing when to configure vs. customize, and having the confidence and communication skills to push back when a request would create unnecessary technical debt. As a senior member of the team, you will shape how we build on ServiceNow: establishing maintainable patterns, improving automation, ensuring data quality in the CMDB, and integrating ServiceNow with other enterprise services via REST/APIs. You will help keep the platform clean, secure, and operationally reliable across environments.

What You’ll Do

Core Responsibilities

• Design, build, and maintain ServiceNow solutions across ITSM and ITOM using configuration-first, upgrade safe patterns.


• Build and improve workflows and automations (Flow Designer, approvals, routing, fulfillment, notifications) with a focus on reliability and reuse.


• Own and evolve ITOM capabilities (e.g., Discovery, Service Mapping, Event/Operations integrations) and improve the quality and usefulness of operational data.


• Advise on best practices for CMDB health and data model discipline (e.g., CSDM-aligned thinking, CI relationships, lifecycle hygiene) in collaboration with platform/process owners.


• Operate a safe delivery lifecycle across Dev/Test/Prod: versioning, controlled transports, documentation, and release readiness.


• Apply security-by-design (roles, ACLs, least privilege) and contribute to ongoing platform hygiene and governance.


• Troubleshoot complex issues across UI, scripting, integrations, performance, and data integrity; resolve quickly and implement preventive fixes.

Strategic Responsibilities

• Set and enforce development standards (scoped apps, reusable components, documentation expectations, and “don’t customize what the platform already does well”).


• Help shape the ServiceNow roadmap with IT and HR: prioritize work, reduce technical debt.


• Improve integration and automation maturity (API design, error handling, monitoring, retry patterns, and runbooks).


• Support platform governance (instance health checks, release readiness, structured upgrade planning/testing).


• Coach stakeholders and peers to raise platform literacy and reduce “snowflake” requests through clear guidance and tradeoff communication.

What You Bring

• 5+ years of hands-on ServiceNow development experience in production environments, owning enhancements from design through deployment.


• Certifications (based on scope): CIS-ITSM and ITOM-related (e.g., Discovery / Service Mapping) where applicable.


• Strong ServiceNow platform development skills (JavaScript/Glide APIs, business rules, client scripts, UI policies, Script Includes, scoped apps, catalog items, workflows).


• Solid ITSM implementation experience (incident/problem/change/request, knowledge, SLAs) and practical delivery history.


• Hands-on ITOM experience (especially Discovery; plus Service Mapping / related ITOM patterns as applicable) and understanding of operational data dependencies.


• Ability to push back constructively: guide stakeholders toward standard, maintainable solutions and explain tradeoffs (upgrade safety, maintainability, licensing, performance).


• Experience with test and release discipline (ATF where appropriate, regression strategy, upgrade-readiness practices).


• Required: ServiceNow Certified System Administrator (CSA) and/or Certified Application Developer (CAD).


• Strong English communication skills and comfort working across IT and HR teams with varying technical depth.

Nice to Have

• Experience working in an Agile environment; SAFe exposure is a plus.


• Experience with identity/group governance integrations (e.g., Entra-based group sync concepts) and role/permission hygiene at scale.


• Exposure to ServiceNow platform operating model topics (instance strategy, release management, operational support, platform reviews/health assessments).


• Experience supporting service catalog / service portfolio management concepts and related roles/workflows.


• Available to work on-site in Noida at least 60%, or willingness to relocate.
