Full Job Description

About This Role

CPC Logistics is seeking a Systems Integration Developer to help build, support, and improve systems that connect operational data, internal applications, file-based workflows, legacy tools, and third-party platforms.

This is a hands-on backend role focused on SQL, integrations, automation, and production troubleshooting. This is not a front-end position and not solely a reporting role however, Power BI is an important component of this role and will be required as part of delivering end-to-end solutions.

The primary database platform for this role is Microsoft SQL Server. Experience with DB2 LUW is helpful but not required. Candidates should be comfortable learning DB2 and working with cross-database integrations.

We are looking for someone who enjoys solving real-world integration problems, working across both modern and legacy systems, and building reliable backend processes.

What You’ll Do

Design, build, and support database-driven integration solutions
Write, optimize, and troubleshoot complex SQL queries, views, and stored procedures
Build and maintain REST API integrations between internal and external systems
Develop and support .NET backend services and automation processes
Support file-based workflows including monitoring, validation, imports, exports, and archiving
Work with DB2 databases and ODBC-based integrations
Support and enhance legacy business logic (VBScript, classic ASP, etc.)
Troubleshoot live issues involving databases, APIs, services, files, and integrations
Implement strong logging, validation, retry logic, and defensive error handling
Develop and support Power BI data models and reporting solutions
Partner with internal teams to deliver reliable technical solutions

What We’re Really Looking For

Strong skills in:

SQL Server and database development
Power BI development and data modeling
API integrations
Backend automation
Cross-system troubleshooting
Legacy-to-modern system support
Reliable production code

This role is a strong fit for someone who can follow data from source to destination, understand how systems interact, and solve integration problems independently.

Required Qualifications

Bachelor’s degree in Computer Science, Information Systems, or related field or equivalent technical experience
Strong experience with Microsoft SQL Server in production environments
Advanced SQL skills (joins, CTEs, aggregations, subqueries, tuning)
Experience with Power BI (data models, reports, performance tuning)
Experience building or supporting REST API integrations
Experience with C# and .NET backend development
Experience troubleshooting live production issues
Experience working with JSON, CSV, Excel, and structured data
Experience working with relational databases in production environments
Experience with DB2 or ability to learn DB2 platform nuances
Strong problem-solving skills and ability to work independently
Strong written and verbal communication skills

Preferred Qualifications

Experience with DB2
Experience using ODBC in application development
Experience building Windows Services or background processes
Experience with .NET 8
Experience with structured logging (Serilog or similar)
Experience with VBScript
Experience with classic ASP
Experience with file-processing automation
Experience in logistics, transportation, or operational environments

What Success Looks Like

In this role, success means you can:

Build integrations that are stable and supportable
Troubleshoot issues across multiple technologies
Support both modern and legacy systems
Reduce manual work through reliable automation
Write clean, maintainable production code

Why Join CPC Logistics

CPC Logistics is a stable, established transportation logistics company with over 50 years in the industry. We provide a supportive environment where developers can make meaningful contributions and grow their careers over the long term.

This is a smaller development team, which means you’ll have a broad canvas to work with and the opportunity to take ownership of important systems and initiatives. While the role will initially focus on immediate business needs, there is significant opportunity to expand into additional development disciplines over time.

This position offers:

Long-term career stability
Growth opportunity within the role
Broad technical exposure across multiple systems
Ownership of meaningful projects and integrations
Self-directed professional growth
Ability to help shape future platforms and integrations

We are looking for someone interested in a long-term commitment who enjoys learning, growing, and making meaningful technical contributions.

Salary Range: $95,000 – $115,000 (based on experience)
Potential for Yearly Performance Bonus - If BOD approved
Full Benefits Package (Health, Dental, Vision)
Paid Time Off and Holidays
