About The Position

At General Motors, product teams are redefining mobility by creating vehicles and experiences designed to be felt, turning today’s impossible into tomorrow’s standard through breakthrough hardware, battery systems, intuitive design, intelligent software, and next-generation safety and entertainment features. The Lab System Integration Engineering (LSIE) team, part of a larger Lab Engineering Operational Support Team, drives common tools and processes for diverse component, subsystem, and vehicle testing laboratories within GM, supporting facilities in Pontiac, Warren, and Milford, Michigan. This LSIE position specifically supports the Tire and Wheel Test Laboratory at the Milford Proving Grounds, focusing on the development and validation testing of current and future vehicle programs and enhancing laboratory infrastructure. The role involves developing and maintaining the software and data infrastructure for the Tire & Wheel Test Laboratory to plan, execute, and analyze development and validation testing. It has a strong focus on C# application development and database design and administration, primarily using PostgreSQL and related data systems. The software built and supported will automate and coordinate laboratory test workflows, interface with test equipment (e.g., MTS systems) and controller networks, and manage the end-to-end flow of test data, including ingestion, processing, storage, and reporting. This position is ideal for individuals who enjoy hands-on lab work, system-level integration, and leveraging modern software and database technologies to improve test capability and efficiency.

Requirements

Bachelor’s degree in Engineering, Computer Science or a closely related discipline.
5+ years of professional software development experience, with a strong emphasis on C# and the .NET ecosystem.
Proven expertise in database development and administration, with hands-on experience in PostgreSQL or similar relational database systems (schema design, complex queries, performance tuning).
Strong understanding and practical use of object-oriented programming concepts and design patterns.
Experience building software that connects to lab equipment, data acquisition systems, or test automation environments and processes resulting data.
Hands-on experience working in a laboratory or test environment, with demonstrated ability to debug issues involving both hardware and software.
Ability to understand and troubleshoot common networking protocols (e.g., TCP/IP, UDP, RS232, Ethernet, Modbus) as they relate to lab and test systems.
Demonstrated ability to work with a high level of autonomy in a complex environment, managing multiple projects, priorities, and deliverables with minimal supervision.
Excellent oral and written communication skills and strong interpersonal skills to work effectively with cross-functional partners and lab staff.
High level of analytical ability to solve unusual and difficult technical problems.
