Junior Automation Engineer Jobs in Minnesota (NOW HIRING)

IPG's Material Processing Systems Group is focused on integrating state-of-the-art IPG lasers into turn-key systems to be used in the semiconductor, medical and other industries. We are seeking a Principal Software Engineer to join the Material Processing Systems Group in the development of advanced laser-based manufacturing systems. This position serves as a principal technical contributor responsible for designing, implementing, and supporting software solutions for IPG's laser processing equipment.

The successful candidate will leverage extensive experience in industrial automation, machine control, and software engineering to develop new machine capabilities, improve existing platforms, and support customer-driven enhancements. While working within established software architectures, this individual will provide technical leadership, mentor less experienced engineers, and help drive engineering excellence across projects.

In addition to software development responsibilities, the Principal Software Engineer will work closely with manufacturing, applications, service, and project teams to support machine builds, system integration, commissioning activities, and project execution on the production floor. This role requires strong system-level problem-solving skills and the ability to coordinate efforts across software, electrical, mechanical, and applications engineering disciplines.

• Analyze machine requirements, customer requests, and engineering specifications to develop software solutions for laser-based material processing systems.
• Design, implement, test, and maintain software features within established machine control architectures.
• Serve as a technical leader and subject matter expert within assigned projects and areas of responsibility, providing technical guidance and collaborating with other principal engineers to align engineering standards and implementation approaches.
• Mentor junior and mid-level engineers through design reviews, code reviews, troubleshooting, and technical guidance.
• Collaborate with electrical, mechanical, controls, and applications engineers to deliver integrated machine solutions.
• Support machine integration, testing, validation, and commissioning activities during machine builds.
• Provide technical leadership for assigned projects and coordination during machine build, integration, commissioning, and acceptance activities, ensuring software deliverables are executed according to project objectives and engineering standards.
• Diagnose and resolve complex system-level issues involving software, motion control, machine vision, communications, and hardware integration.
• Drive software quality through adherence to coding standards, testing practices, and maintainability guidelines.
• Evaluate and implement improvements to existing machine architectures, software frameworks, and development processes.
• Support field service teams and customers in resolving advanced software and machine performance issues.
• Participate in customer visits and occasional domestic or international travel to support installations and project execution.

Requirements:

• 15+ years professional software engineering experience.
• Demonstrated experience leading technical projects and mentoring engineers.
• BSCE, BSCS, BSEE, or equivalent. MS, a plus.
• Demonstrated history of solving complex technical challenges in industrial automation, CNC, robotics, or manufacturing systems.
• Expert proficiency in Microsoft C#/.NET development.
• Experience developing industrial automation, CNC, robotics, or precision automation equipment software.
• Strong understanding of multithreaded and distributed systems.
• Experience integrating motion control systems, machine vision systems, and industrial hardware.
• Ability to manage multiple projects and priorities in a fast-paced manufacturing environment.
• Experience with Application Lifecycle Management (ALM) tools such as Microsoft Azure DevOps and Git
• Strong understanding of object-oriented design principles and software development best practices.
• Strong troubleshooting skills at an overall system level (software, electrical and mechanical).
• Strong professional organization and task priority skills.

Experience Desired (not required):

• Experience with advanced software testing technologies in .NET
• Experience using a PC to interface with external sensors and control peripheral devices via vendor SDK, serial or TCP/IP communications.
• Experience with web services and APIs including ASP.NET, JSON, and RESTful interfaces.
• Experience developing automated manufacturing equipment, particularly factory-connected systems and Industry 4.0 solutions.
• Experience with databases (Microsoft SQL Server).
• Motion control systems (Aerotech A3200, Aerotech Automation 1, ACS).
• Machine vision (Dalsa/Sapera/Sherlock, Cognex, Matrox).
