About the Role

Advanced Navigation is seeking a Finance Systems Manager to lead the Finance workstream of a major operational infrastructure transformation, replacing legacy systems with Microsoft Dynamics 365. This high-impact role requires a blend of program management and finance systems expertise, acting as the primary point of accountability for financial outcomes and bridging internal teams, IT, and the implementation partner.

Responsibilities

Own the Finance workstream of the MS Dynamics 365 implementation, serving as the strategic liaison between internal finance stakeholders and the external implementation vendor.
Translate complex business requirements across AP, AR, General Ledger, Fixed Assets, Intercompany transactions, and Financial Reporting into functional Dynamics configuration decisions.
Lead the migration framework—including chart of accounts mapping, opening balances, and master data cleansing—across our five legal entities in Australia, the UK, and the US.
Design robust testing scripts, coordinate internal finance team participation, and actively manage defect resolution with the vendor during User Acceptance Testing (UAT).
Design and deliver a comprehensive training and change management program, ensuring our global finance team is capable, confident, and ready for day-one go-live.
Partner with IT and the CRM workstream to define and validate integration points for billing workflows, revenue recognition, payroll, expenses, and banking.
Act as the primary system administrator for Dynamics Finance modules post go-live, managing user access, security role design, and ongoing software optimization.
Establish a formal governance framework for change requests and master data ownership, partnering with the Manager of Reporting & Analytics to ensure data structures support clean downstream reporting.

Requirements

Minimum 6 years of experience across finance systems, ERP implementations, or finance operations, featuring at least two full-cycle ERP deployments in a hands-on lead capacity.
Deep functional knowledge and hands-on experience with Microsoft Dynamics 365 Finance & Operations (or Dynamics AX) as a functional lead or systems manager is essential.
Strong background operating within a multi-entity, multi-currency corporate structure; direct experience managing Australian and US entities is highly desirable.
Experience within a technology, hardware, manufacturing, or defense-adjacent business is a distinct advantage given our product complexity and US defense-subsidiary framework.
Ability to write and interpret functional design documents, legal entity configurations, number sequences, posting profiles, and data migration specifications.
Proven ability to manage external software integrators, holding them strictly accountable to agreed scope, timelines, budget, and quality parameters.
Natural communication skills with the ability to build immediate trust with cross-functional teams undergoing significant operational change, alongside the executive presence to report program risks directly to the CFO.
