Senior Systems Specialist (ERP) - Middlesbrough

Release, Environment & ERP Lifecycle Management

• Own environment and release strategies across Dev, Test, UAT, Pre-Production and Production, adapting controls to the different deployment models used by AX, BC and F&O.
• Lead major/minor ERP upgrades, cumulative/platform updates, hotfixes, ISV upgrades, extension releases, API deprecations and security patching across multiple country instances.
• Plan upgrades as an end-to-end dependency exercise, validating Microsoft base application, localisation, ISV, custom code, interface and reporting compatibility before production deployment.
• Establish and operate CI/CD and release controls using Azure DevOps and relevant Microsoft lifecycle/admin tooling, including automated build/test, artefact promotion, approvals, audit trail and rollback.
• Define regression and cutover strategies that test critical country processes, statutory functions, integrations and ISV-dependent business scenarios before release.
• Support ERP rationalisation and modernisation roadmaps, including controlled transition from legacy AX/NAV estates to BC and/or F&O where this is the approved target architecture.

Operations, Performance & Problem Management

• Own ERP operational health and service targets, using application telemetry, SQL/database diagnostics, batch monitoring, integration logs and platform monitoring to identify emerging issues.
• Lead resolution of complex, cross-platform incidents and problem-management root cause analyses, coordinating Microsoft, ISVs, infrastructure teams and internal specialists where ownership is shared.
• Drive performance tuning and capacity planning across ERP application tiers, databases, integrations and supporting Azure services.
• Maintain robust backup/restore, disaster recovery, support runbooks and technical operating procedures aligned to agreed RTO/RPO and service requirements.

Security, Access & Compliance

• Apply secure-by-design controls across ERP identity, roles, permissions, segregation of duties, privileged access, service accounts and integration identities.
• Ensure ERP designs and changes meet applicable UK/EU data residency, GDPR, Cyber Essentials Plus and ISO/IEC 27001 requirements, together with relevant contractual and sector controls.
• Maintain auditable change, access and deployment records and ensure vulnerabilities, unsupported components and technical exceptions are identified and remediated through controlled plans.

Stakeholder, Vendor & Delivery Management

• Translate complex business requirements into technical ERP designs, clearly separating global/common requirements from country, entity and ISV-specific needs.
• Manage and technically assure third-party ERP partners, developers and ISVs, holding suppliers to agreed architecture, coding, documentation, security, testing and support standards.
• Coordinate roadmaps across Microsoft, ISV and internal delivery teams so release sequencing, end-of-support dates and platform dependencies are visible and actively managed.
• Provide clear technical decision records, architecture diagrams, runbooks and handovers to BAU/support teams.

Team Leadership & Technical Mentoring

• Act as the senior escalation point for analysts and technical specialists working across ERP, integrations and connected business systems.
• Mentor colleagues in structured troubleshooting, dependency analysis, release management and safe support of complex multi-layer ERP environments.
• Review and sign off technical fixes and changes, ensuring appropriate standards, peer review and change governance are followed.

• Demonstrable experience managing layered ERP architectures comprising Microsoft base applications, country/localisation components, multiple third-party ISVs, bespoke extensions and integrations.
• Strong understanding of AL/C-AL and X++ concepts sufficient to diagnose issues, review technical designs/code and work effectively with specialist developers; hands-on development capability in one or more Dynamics technologies is advantageous.
• Proven delivery of ERP upgrades, migrations, platform changes and controlled releases where compatibility across Microsoft, ISV and custom layers must be actively managed.
• Experience with Dynamics integration patterns including REST/OData, APIs, data entities, webhooks/business events, OAuth and Azure integration services such as API Management, Logic Apps, Functions and messaging.
• Strong environment and release-management knowledge, including Azure DevOps, CI/CD, automated testing, artefact promotion, lifecycle/admin tooling and robust rollback/cutover planning.
• Good SQL Server and database diagnostic skills, with the ability to investigate performance, data integrity, batch and cross-system issues in ERP contexts.
• Understanding of multi-country ERP considerations including legal entities, localisation, tax/statutory requirements, currencies, languages, data residency and controlled variation from global standards.
• Strong vendor and ISV management skills, with the ability to challenge technical proposals, coordinate multiple suppliers and maintain clear accountability across shared solution boundaries.
• Secure-by-design mindset covering identity, permissions, segregation of duties, auditability, data protection and controlled privileged access.
• Excellent problem solving and technical communication skills, including the ability to explain complex ERP dependencies and risks to both technical and non-technical stakeholders.

Desirable

• Experience in Engineering, Construction, Energy, Industrial Services or similarly complex project-led environments.
• Experience of vertical/industry ISVs layered on Microsoft Dynamics ERP platforms, particularly where multiple ISV products and localisations must coexist.
• Power Platform and Dataverse experience, including Power Apps, Power Automate and governance of ERP-adjacent low-code solutions.
• Familiarity with Azure data tooling and modern analytics platforms including Data Factory, Fabric, Databricks and lakehouse concepts.
• ITIL/Agile delivery experience, service transition and formal change/CAB participation.
