Senior ServiceNow Developer
Department: Cyber Services and Capabilities
Employment Type: Full Time
Location: ESP Madrid

Description
The Senior ServiceNow Developer is the most senior hands-on technical authority for the ServiceNow platform underpinning our cybersecurity managed services. The role designs, builds and maintains complex, heavily customised applications in an environment where out-of-the-box functionality is not sufficient: scoped applications, custom data models, advanced server- and client-side scripting, and integrations with security tooling and customer environments. It demands expert-level JavaScript, a rigorous approach to performance, maintainability and upgradeability, and the judgement to know when to configure, when to customise, and when to challenge the requirement. Because the platform delivers a live managed service to external customers, the post holder works directly with customers and service stakeholders on requirements, technical escalations and service impact, and is accountable for solutions that hold up under contractual service commitments.



As the technical lead within the development team, the post holder sets the technical standard, owns code review and architectural direction, and mentors and develops the wider team.

Key Responsibilities

•
Technical Leadership: Act as the technical authority for the platform: own architectural direction and technical standards, make and document the significant design decisions, and provide the final technical sign-off before code is promoted.

•
Complex Application Development: Design and build scoped applications, custom data models and business logic that go well beyond out-of-the-box capability, while keeping the instance supportable and upgradeable.

•
Advanced Scripting and JavaScript Engineering: Write, review and refactor advanced server-side and client-side JavaScript across Script Includes, Business Rules, GlideAjax, Scripted REST APIs, UI Scripts, UI Actions and Service Portal wi
