The implementation partner's PM owns their delivery; you own ours — the people, the decisions, the data, and everything that has to come from MacDonald-Miller for the implementation to land on time and on budget. You'll also coordinate closely with the Project Managers leading our parallel SageHCM (payroll/HRIS) and BuildOps (field service) implementations, since the three programs share data, dependencies, and end users. What you'll own This is a dedicated, full-time role from kickoff through hypercare. As the ERP Project Manager, you will lead the day-to-day execution of the D365 F&SC implementation from MacDonald-Miller's side. You will manage the internal project plan, run the BPO and SME working cadence, hold the implementation partner accountable to their statement of work, co-prepare and co-present at Steering Committee meetings alongside the partner PM, and keep the program moving when decisions stall. You will work alongside our Product Owner, Finance BPO, and the functional SME teams across Finance, Project Accounting, AR, AP, Payroll, Supply Chain, and Operations through every phase of the methodology — Joint Process Design (JPD) sessions, Conference Room Pilots (CRPs), data migration iterations, UAT, and cutover. Top deliverables in the first year to be a hero • Project execution and governance. Build and maintain the internal project plan that mirrors and complements the implementation partner's. Run the weekly cadence with BPOs and SMEs, manage the RAID log, and co-prepare and co-present materials at monthly Steering Committee reviews alongside the partner PM. Drive accountability and delivery, manage scope, schedule, budget, risks, issues, communications, and change control. Hold the implementation partner accountable to their commitments without burning the relationship., • SME and BPO orchestration. Make sure the right people from Finance, Project Accounting, AR, AP, Payroll, Supply Chain, Service Operations, and Project Operations show up prepared for design sessions, configuration reviews, and UAT. Protect their time, sequence their work, and unblock them when they're stuck., • Cross-program coordination. Partner closely with the BuildOps PM and the SageHCM PM to align timelines, surface integration dependencies early, and prevent the three programs from making conflicting decisions. Establish and run the integration governance forum across all three workstreams., • Data migration leadership. Co-lead the data migration workstream with our Data Migration BPO. Drive the cleanup, mapping, and validation of master data coming out of GP/Wennsoft — customers, vendors, items, jobs, GL, open AR/AP — and make sure mock conversions and cutover rehearsals happen on schedule., • Change management partnership. Work hand-in-hand with our OCM lead to make sure training, communications, and readiness activities are sequenced into the plan — not bolted on at the end. Translate technical milestones into what end users actually need to know and do., • Risk and decision management. Surface risks early, drive decisions to closure, and prevent scope creep from quietly inflating the budget. When trade-offs are needed between scope, schedule, and cost, frame them clearly for executives and recommend a path., • Go-live and stabilization. Lead cutover planning and execution. Run the hypercare period after go-live and make sure the operational handoff to IT and the business is clean.Required qualifications, • 8+ years of project management experience, including at least one full-cycle ERP implementation taken from discovery through go-live and stabilization as the customer-side PM (not as the system integrator), • Direct experience with Microsoft Dynamics 365 Finance & Supply Chain, Dynamics AX, or a comparable tier-one ERP (SAP, Oracle, NetSuite at scale), • Demonstrated experience managing an external implementation partner — holding them accountable to scope, schedule, and quality without the relationship breaking down, • Strong working knowledge of core financial processes: GL, AR, AP, project accounting, procurement, fixed assets, and month-end close, • Experience leading or co-leading an ERP data migration effort, including cleanup, mapping, validation, and cutover, • Excellent written and verbal communication, with the ability to move fluidly between executive updates, SME working sessions, and technical design conversations, • PMP, PRINCE2, or equivalent project management credential, or comparable demonstrated experiencePreferred qualifications, • Experience implementing D365 F&SC specifically with a major D365 implementation partner, • Industry experience in commercial HVAC, mechanical contracting, construction, or another field service-heavy trade contractor environment — enough to understand why a missed dispatch, a delayed invoice, or a broken job cost report is a serious problem, • Experience migrating off Microsoft Dynamics GP and/or Wennsoft (Signature/Job Cost/Service Management), • Experience running a workstream alongside a parallel HRIS, payroll, or field service implementation, with shared integration dependencies, • Familiarity with integration concepts (REST/SOAP APIs, middleware, master data governance) — enough to pressure-test integration designs and catch hand-waving, even if you're not building them, • Experience with construction or project-based accounting (WIP, percentage-of-completion, job costing) Benefits Compensation: $140,000–$185,000 annually.
