KORE1, a nationwide provider of staffing and recruiting solutions, has an immediate opening for a Senior ERP Architect / Engineer – Epicor Kinetic | ERP Modernization, C# & SQL Server .

About the Opportunity

We are seeking a hands-on Senior ERP Architect / Engineer to take technical ownership of an existing Epicor Kinetic environment and help drive ERP modernization, business process optimization, and application integration initiatives.

Following a recent organizational separation, the company now operates its own Epicor environment and has identified a growing need for dedicated technical expertise. The existing IT team supports the broader infrastructure and application landscape but needs a senior Epicor specialist who can evaluate the current environment, guide technical decisions, and execute hands-on development and configuration work.

The organization currently runs Epicor Kinetic 2022.1 using the Windows Smart Client , rather than the newer browser-based Kinetic interface. The environment includes legacy customizations, modified screens, integrations, and externally developed applications, some of which lack original source code or technical documentation.

A major responsibility of this position will be to evaluate the existing Epicor environment and determine the appropriate modernization strategy , including whether and when to transition to the browser-based Kinetic interface. The company has not committed to an upgrade timeline and is looking for someone who can assess the current state, understand business requirements, evaluate technical dependencies, and recommend the most practical path forward.

The broader objective is to simplify and standardize the ERP environment by maximizing native Epicor functionality, reducing unnecessary customizations, improving business processes, and implementing scalable, maintainable solutions.

This role combines ERP architecture, hands-on engineering, business analysis, and technical leadership . The successful candidate must be capable of working directly in Epicor while partnering with stakeholders across operations, finance, accounting, inventory, purchasing, and other business functions to understand workflows and translate business needs into effective technical solutions.

This is an individual contributor position with significant technical ownership and influence. The individual will collaborate with internal IT resources, business stakeholders, and external consultants as needed, but will not have direct reports.

Key Responsibilities

Serve as the primary technical subject matter expert for the organization's Epicor Kinetic environment, providing hands-on development, configuration, troubleshooting, integration, and architectural guidance.

Conduct a comprehensive current-state assessment of the Epicor Kinetic 2022.1 Windows Smart Client environment , including existing configurations, customizations, integrations, external applications, workflows, and technical dependencies.

Lead the technical evaluation of transitioning to the browser-based Epicor Kinetic interface , assessing feasibility, timing, upgrade readiness, business value, and the impact on existing processes and customizations.

Develop modernization recommendations and a practical ERP roadmap, determining whether business process improvements and enhancements should be implemented in the current environment or as part of a future upgrade.

Partner with business stakeholders to understand current workflows, identify inefficiencies, clarify requirements, and recommend improvements through process optimization, automation, and standardization.

Apply business process analysis and value stream mapping principles to evaluate operational workflows before determining how Epicor should support them.

Assess legacy customizations, including modified screens, undocumented functionality, and externally developed applications, to determine whether they should be maintained, replaced, retired, or rebuilt using native Epicor capabilities.

Prioritize out-of-the-box Epicor functionality and configuration over unnecessary custom development, balancing business requirements with long-term maintainability and upgrade compatibility.

Design, develop, configure, test, and implement Epicor enhancements, business process automations, customizations, and integrations.

Develop and maintain technical solutions using C#/.NET, SQL Server, Epicor Business Activity Queries (BAQs), Business Process Management (BPMs), Epicor Functions, and REST APIs .

Support integration initiatives involving Epicor and external platforms, including Salesforce, banking and financial systems, shipping carriers, and other enterprise applications.

Contribute to planned ERP initiatives involving warehouse operations, material requirements planning (MRP), shipping integrations, financial structures, and operational process improvements.

Troubleshoot ERP application issues, integration failures, data inconsistencies, and legacy customization problems, identifying root causes and implementing sustainable solutions.

Collaborate with internal IT resources on ERP administration, deployment, troubleshooting, and ongoing support, providing technical guidance and knowledge transfer where appropriate.

Evaluate third-party applications and existing Epicor integrations as alternatives to custom-built solutions when native functionality cannot fully meet business requirements.

Support reporting and data access requirements as needed, including BAQ development, existing Epicor reports, and helping business users become more self-sufficient.

Establish and maintain technical documentation, development standards, configuration practices, and change management processes.

Coordinate with external Epicor consultants, implementation partners, and vendors when specialized expertise or additional project resources are required.

Strong technical experience with Epicor Kinetic , including development, configuration, customization, integration, and troubleshooting in a production enterprise environment.

Strong communication, collaboration, and stakeholder management skills, with the ability to explain technical concepts, challenge assumptions constructively, and guide business users toward practical solutions.

Experience with value stream mapping, business process reengineering, workflow optimization, or ERP process standardization is highly desirable.

Ability to work fully onsite or on a hybrid schedule in Irvine, CA.

Must be willing and eligible to transition to a direct full-time employee following the projected contract period.
