D365 Developer Jobs in Pennsylvania (NOW HIRING)

How You’ll Contribute:

 We are seeking a highly experienced Solution Architect to own the end-to-end technical and functional architecture for a dual Dynamics 365 program spanning D365 Customer Engagement (CE) and D365 Finance & Operations (F&O). This role is central to implementation of new CE and F&O instances, alongside a complex multi-source ERP data migration into the new environment. The Solution Architect will define the target-state architecture, set data migration and integration strategy, and serve as the primary technical counterpart to our Systems Integrator (SI) partner — validating their designs, resolving technical disputes, and ensuring the delivered solution meets enterprise standards. You will architect the solution and hold the SI/project team accountable to build it correctly, while partnering closely with internal project teams. 

Location: Virtual U.S. position; preferred work location/time zone is Eastern (EST/ET) or Central (CST/CT).

What You’ll Do:

• Own the target-state solution architecture across D365 CE and D365 F&O, including how the two systems integrate (dual-write, Dataverse, custom integration patterns) 

• Design the enterprise data migration architecture across legacy source systems (Great Plains, D365 F&O, Bright Pearl, MAS 100, MAS 200), including source-to-target mapping, data cleansing rules, sequencing, and cutover strategy 

• Act as the primary technical governance point: review and approve technical design documents, functional specifications, and integration designs before build begins 

• Identify and resolve architectural risks, technical debt, and design conflicts raised by the SI, internal team, or business stakeholders 

• Define the integration architecture across CE, F&O, EDI, and any third-party/middleware systems required for go-live 

• Partner with business and project team to translate business requirements into technical and functional design decisions 

• Set standards for security role design, environment strategy (DEV/QA/UAT/PROD), extensibility patterns, and code/configuration governance  

• Own the "build vs. configure vs. customize" decision framework, steering the program toward standard functionality where possible and justifying extensions where necessary 

• Lead architecture review sessions at key program milestones (design sign-off, pre-UAT, pre-cutover) 

• Define the data migration validation and reconciliation approach to confirm accuracy across all five legacy sources post-migration 

• Assess feasibility and technical risk for scope changes raised mid-program and advise PMs and leadership accordingly 

• Document the end-state architecture, integration map, and data lineage for long-term support handoff to the internal Technical Lead 

• Provide technical escalation support during UAT and cutover, working alongside the SI and Technical Lead to triage and resolve critical issues 

• Contribute to and help shape the broader technology roadmap as it relates to the Dynamics ecosystem, including future Power Platform, Dataverse Fabric, and AI/automation opportunities 

• Mentor internal Business Analysts and the Technical Lead on architectural best practices to build long-term internal capability 

• Present architecture decisions, risks, and trade-offs to CIO/ELT-level stakeholders in clear, non-technical business terms when required 

What You’ll Bring:

Required Skills/Qualifications:

• Minimum 10+ years in enterprise systems architecture, with at least 5+ years specifically architecting Dynamics 365 solutions 

• Demonstrated experience architecting both D365 CE and D365 F&O — not one or the other — including how they integrate 

• Prior experience leading a multi-source ERP-to-D365 data migration/consolidation; direct exposure to legacy platforms such as Great Plains, Bright Pearl, MAS 90/100/200, or comparable mid-market ERPs is a strong plus 

• Track record architecting greenfield D365 implementations (not just upgrades or extensions of an existing instance) 

• Deep understanding of Dataverse, dual-write, Power Platform integration patterns, and D365 F&O data structures/extension models 

• Proven experience acting as the technical counterparty to a Systems Integrator — reviewing SI design artifacts, holding SI teams accountable, and making final architectural calls 

• Strong grasp of data migration methodology: mapping, cleansing, sequencing, reconciliation, and cutover planning at an enterprise scale 

• Experience defining integration architecture involving EDI and third-party/middleware systems 

• Ability to operate at both a hands-on design level (data models, integration patterns) and an executive communication level (CIO/ELT presentations) 

• Strong facilitation skills — comfortable running architecture review and design sign-off sessions with mixed technical/business audiences 

• Prior experience mentoring technical leads or developers and establishing architectural governance standards 

• Experience working in a PE-backed or high-growth environment where program timelines and board visibility are significant is a plus
