Senior ServiceNow Developer
Role Summary
The
Senior ServiceNow Developer
is a seasoned, hands-on technical contributor responsible for
design realization, implementation, maintenance, and optimization
of ServiceNow solutions across the
SENSE/cSENSE ecosystem
. Working within
hybrid teams
and
Agile Release Trains (ARTs)
, this role delivers
secure, performant, and scalable
implementations based on solution designs defined by
Solution Architects
.
Beyond delivery, the Senior Developer acts as a
quality owner and technical guide
—driving clean code practices, reducing technical debt, strengthening engineering standards, and mentoring junior developers and SDA students. The role balances
independent ownership of complex stories/features
with strong collaboration across architects, product, operations, and integration stakeholders.
Key Responsibilities
Development & Implementation
- Translate approved solution designs into production-ready ServiceNow implementations aligned with platform best practices.
- Develop across ServiceNow capabilities such as:
- ITSM / CSM / FSM (and/or other product lines),
- Custom applications, Flow Designer, IntegrationHub,
- Service Portal and/or UI Builder,
- Scripting and automation: Business Rules, Script Includes, Client Scripts, Scheduled Jobs, UI Policies, and related platform components.
- Implement clean, maintainable JavaScript (TypeScript as a plus), following SOLID principles, code readability standards, and platform performance guidelines.
- Own story-level implementation decisions (within approved designs), including code structure, testing strategy, and deployment readiness.
Integration & Data Flows
- Build and maintain integrations with external systems (e.g., Azure API Management, SnapLogic, SAP, Azure Blob Storage) using established enterprise patterns.
- Implement and support:
- REST/SOAP APIs, authentication patterns, payload contracts,
- Import Sets / Transform Maps, data normalization, reconciliation,
- Scheduled interfaces and event-driven flows where applicable.
- Design robust integration behaviors including logging, retries, error handling, compensating actions, and operational traceability.
- Support incident/problem resolution by analyzing logs, tracing data flows, and identifying root causes in owned applications and integrations.
Quality, Peer Review & Governance
- Conduct and champion high-quality peer reviews with focus on:
- maintainability, reuse, and simplicity,
- platform performance and scalability,
- security (least privilege, safe scripting, secure integrations),
- adherence to engineering standards and guardrails.
- Ensure changes meet definition of done, including documentation, tests, review sign-off, and readiness for higher-tier promotion.
- Proactively identify, communicate, and reduce technical debt, proposing improvements and implementing refactoring when appropriate.
- Adhere to technical governance: ensure implementations receive authorized technical approval (Solution Architect or nominated authority) before promotion.
Operational Stability & Supportability
- Implement solutions with “secure-by-design” and “privacy-by-design” principles; ensure no PROD data is used on sub-production instances.
- Minimize production incidents through quality engineering, monitoring-friendly implementation, and robust error handling.
- Participate in root-cause analysis and implement permanent fixes for recurring issues in owned areas.
Continuous Improvement & ART Ways of Working
- Contribute to evolving development standards, patterns, reusable components, and delivery guardrails across the team/vertical.
- Actively stay current with ServiceNow releases, new features, and roadmap implications; keep certifications active.
- Collaborate in ART ceremonies and Agile delivery practices (planning, refinement, PI execution support), supporting predictable and transparent delivery.
Mentoring of juniors
- Mentor junior developers and SDA (Summer Dev Academy) students through:
- onboarding and guided ramp-up plans,
- pair programming and hands-on coaching,
- structured feedback via code reviews and technical check-ins.
- Raise team capability through:
- knowledge-sharing sessions (brown bags, demos, guilds),
- practical documentation (how-to guides, patterns, do/don’t lists),
- encouraging platform best practices and sustainable engineering habits.
- Support onboarding of new team members (internal/external) on:
- platform conventions and coding standards,
- application context and integration landscape,
- delivery lifecycle and governance expectations.
Required Skills And Qualifications
Technical Expertise
- 5+ years of ServiceNow development experience, preferably across at least two product lines (e.g., ITSM, CSM, FSM, HRSD, Discovery) and/or custom app development.
- Strong hands-on expertise in:
- ServiceNow scripting: server-side & client-side JavaScript (TypeScript is a plus),
- Flow Designer, IntegrationHub, and automation patterns,
- ATF (Automated Test Framework) and pragmatic testing approaches,
- UI delivery using Service Portal and/or UI Builder.
- Proven integration engineering experience:
- REST/SOAP, import/export patterns, Transform Maps,
- robust interface design (logging, retries, fault handling),
- familiarity with enterprise integration tooling (e.g., Azure API Management, SnapLogic, SAP) is a strong plus.
- Experience with ServiceNow delivery practices:
- update sets and/or Source Control Integration,
- CI/CD concepts and controlled promotions across instances.
- performance optimization (queries, script efficiency, platform limitations),
- secure development practices (roles, ACLs, secure APIs),
- clean code principles (SOLID, readability, maintainability).

Mentoring & Communication
- Demonstrated ability to lead by influence: improving outcomes through guidance, review quality, and constructive coaching.
- Strong problem-solving skills; comfortable owning complex deliverables end-to-end with minimal supervision.
- Clear communicator within technical teams and across stakeholders; able to explain technical decisions in accessible terms when needed.
- Highly collaborative and effective in global, multicultural, hybrid teams (internal/external; near/offshore).
