Job Summary

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

Key Responsibilities Development & Implementation · Translate approved solution designs into production-ready ServiceNow implementations aligned with platform best practices. · Develop across ServiceNow capabilities such as: o ITSM / CSM / FSM (and/or other product lines), o Custom applications, Flow Designer, IntegrationHub, o Service Portal and/or UI Builder, o 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: o REST/SOAP APIs, authentication patterns, payload contracts, o Import Sets / Transform Maps, data normalization, reconciliation, o 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: o maintainability, reuse, and simplicity, o platform performance and scalability, o security (least privilege, safe scripting, secure integrations), o 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: o onboarding and guided ramp-up plans, o pair programming and hands-on coaching, o structured feedback via code reviews and technical check-ins. · Raise team capability through: o knowledge-sharing sessions (brown bags, demos, guilds), o practical documentation (how-to guides, patterns, do/don’t lists), o encour
