ServiceNow Developer

Job Summary

To design, build and deploy AI-powered workflow solutions on the ServiceNow platform, with specialist depth in NowAssist wit

Takes agreed requirements and process design through to working, tested, supportable configuration, making the technical decisions that determine whether a solution scales, performs and can be maintained. Acts as the senior technical voice in the Workflow Development team, setting build standards, guiding less experienced developers, and advising on what the platform can and cannot sensibly do.

What You Will Do

Operating within the Services function, as part of a new Workflow Development team, the Senior ServiceNow Developers most important duties and responsibilities include:

• Designing and building solutions across the ServiceNow platform, with particular focus on NowAssist capabilities (generative AI skills, AI agents, Virtual Agent, AI Search).
• Configuring and tuning NowAssist skills - including prompt design, grounding against the right data sources, and evaluating output quality before release.
• Building and extending TPSM capability, including case management, install base and product catalogue, entitlements, order management and Service Bridge integrations where relevant.
• Translating requirements and process designs into technical designs, then into configuration and code, making and documenting the trade-offs along the way.
• Building integrations between ServiceNow and adjacent systems using appropriate patterns (REST/SOAP, IntegrationHub, Flow Designer, MID Server) and defending the choice of pattern.
• Writing and maintaining automated and manual unit tests, and supporting the BA through end-to-end and multi-application testing.
• Owning the technical quality of releases - code review, adherence to platform best practice, upgradeability, and keeping customisation to the minimum the requirement genuinely needs.
• Taking changes through the platform governance route, including CAB submission, technical risk assessment and post-release verification.
• Mentoring and technically guiding other developers, and setting the teams development standards and definition of done.
• Diagnosing and resolving complex platform issues, including those arising from ServiceNow family releases and upgrades.
• Working with the BA, process lead and SMEs to challenge requirements where a simpler or more sustainable technical approach exists.

What You Will Have

Essential:

• ServiceNow Certified Application Developer, plus CIS accreditation in CSM, TPSM/TSM or ITSM.
• A minimum of 6years hands-on ServiceNow development experience, including complex, multi-application delivery.
• Deep working knowledge of the ServiceNow platform: data model, ACLs, Flow Designer, Business Rules, Script Includes, Client Scripts, UI Builder / Service Portal, and Update Set and source control release management.
• Strong JavaScript, with the judgement to know when scripting is the right answer and when configuration is.
• Practical experience building with NowAssist - generative AI skills, AI agents or Virtual Agent - in a production or near-production setting, not just proof of concept.
• Experience with TPSM, CSM or a comparable customer-facing ServiceNow product line, including install base and entitlement models.
• Proven integration experience across REST/SOAP, IntegrationHub and MID Server, including handling authentication, error and volume concerns.
• Experience through full upgrade cycles, with an understanding of what makes a build survive a family release.
• Able to explain technical decisions and risk clearly to non-technical stakeholders, and to push back constructively when a requirement is unworkable.
• Experience mentoring or technically leading other developers.

Desirable:

• Experience with Now Assist Skill Kit, AI Search tuning, or the Generative AI Controller for third-party LLMs.
• Understanding of AI governance in practice - data handling, DPIA input, model change management, output evaluation.
• Experience in a software vendor, MSP or technology provider environment where the customer base sits on the platform.
• Familiarity with Automated Test Framework and CI/CD tooling for ServiceNow.
• Exposure to Performance Analytics or reporting design for AI agent effectiveness.
