## About the Role

Finance, Healthcare, Artificial Intelligence (AI), Cloud Computing, Investment Strategy, Leadership, Business Solutions, Consulting, Software Engineering, Microsoft Product Family, * Deep, proven experience with Dynamics 365 - customizations, plugins, integrations, and navigating major upgrades

 * Hands-on expertise in C#/.NET and the broader Microsoft stack (Azure, SQL Server)
 * Strong integration experience with enterprise tools (ServiceNow, Power BI, or similar)
 * Track record of leading or mentoring development teams

You're the Right Fit If:

 * You think in systems, not just features - you understand data lineage, governance, and why metadata matters as much as the data itself
 * You're energized by building a capability from the ground up, not inheriting someone else's playbook
 * You can communicate architecture decisions to both developers and executives
 * You've worked in environments where engineering rigor and long-term durability are non-negotiable
 * Legacy modernization excites you - you see Lotus Notes migration as a design challenge, not a chore

## Description

You'll architect and lead a modern Microsoft ecosystem supporting a sophisticated engineering organization:

 * Core Platform: Microsoft Dynamics 365 (CRM/Sales, Finance, HR, Expenses)
 * Analytics: Power BI consuming Dynamics data
 * Integrations: ServiceNow (customer support), shipping systems, product delivery workflows
 * Legacy Modernization: Lotus Notes data and workflows (Keys, Expenses, HR history) - a migration opportunity, not just maintenance
 * Planned Builds: mobile time tracking, contract/SOW management

What You'll Do

 * Own the architecture - all technical decisions for D365 customizations, plugins, and integrations across the enterprise
 * Write and review production code (C#, .NET, Azure, SQL Server) as a hands-on technical leader, not just a diagram-drawer
 * Lead and mentor a growing team of application developers (building from a small core team)
 * Design upgrade-resilient patterns that protect the business from breaking changes during platform updates - this company builds systems meant to last decades, and they expect the same durability internally
 * Drive legacy modernization - migrate Lotus Notes workflows into D365, applying the same rigor this company brings to migrating enterprise clients off COBOL and legacy ETL tools
 * Collaborate with Program Managers, Systems teams, and executive stakeholders to align D365 strategy with business priorities
