Test Engineer

Milwaukee Electronics is seeking an experienced Test Engineer to join our R&D lab in Glendale, WI, and become a technical leader who shapes the future of test engineering for our organization. This is a rare opportunity to drive test strategy and automation direction while working on cutting-edge products across two domains: Sensometer remote monitoring systems and advanced automation controls.

You'll work alongside our small, agile development team supporting two critical product development projects with diverse architectures and technologies. As we expand our test engineering capabilities, you'll mentor junior engineers and establish test practices that scale with our growth.

What makes this role unique: We offer a distinctive balance of autonomy and support. You'll have the independence to drive your technical direction with minimal oversight, backed by collaborative leadership that provides the resources you need. If you can clearly communicate your needs and deliver on goals, you'll thrive here. We value ownership, initiative, and the ability to work both independently and cross-functionally.

Why Join Us

Leave the anti-culture behind.

If you've worked at large manufacturers, you know the frustrations: bureaucracy that buries good ideas, rigid hierarchies that waste your expertise, and being pigeonholed when you're capable of more.

Here's what's different: You'll work across product lines and technologies because we can't afford unitaskers. You'll have direct access to leadership that trusts your judgment and moves at engineering speed, not political speed. You'll build our test engineering function and shape how we work - your ideas won't vanish into committee hell.

We lead with humanity. We value clear communication, ownership, and people who care about the work and each other. If you're ready to be valued as a complete professional rather than a resource allocation, let's talk.

What You'll Do

• Lead test strategy: Drive the technical direction of test and test automation practices across the organization
• Design, develop, and execute comprehensive test plans for firmware and system-level validation
• Build and maintain automated test frameworks using Python or similar languages
• Perform hands-on debugging and root cause analysis using industry-standard tools (logic analyzers, oscilloscopes, protocol analyzers, debuggers)
• Collaborate closely with firmware and hardware engineers to identify and resolve issues early in the development cycle
• Establish test best practices and mentor junior test engineers and interns
• Drive improvements in test coverage, automation, and reliability metrics
• Support multiple concurrent projects with different technology stacks
• Take ownership of complex test challenges with the autonomy to implement solutions

What You Bring

Required:

• 3 years of experience in firmware test, system test, and/or test automation
• Strong proficiency with Python or another scripting language commonly used in test automation (e.g., Python, C#, JavaScript)
• Demonstrated expertise with test and debug tools, including:
  • Logic analyzers
  • Oscilloscopes
  • Digital multimeters (DMM)
  • Protocol analyzers (Wireshark, etc.)
  • Terminal/command line interfaces
  • In-circuit debuggers (JTAG, SWD)
• Experience testing embedded systems and/or firmware
• Strong problem-solving skills and attention to detail
• Excellent communication skills and ability to work cross-functionally

Preferred (in priority order):

• Experience with IoT products, remote monitoring systems, and RF communication interfaces (cellular, satellite) - highly valued
• Knowledge of industrial automation, networking protocols (Ethernet/IP, EtherCAT, PROFINET), BLDC motor controls, dynamometers, brakes, and speed-torque curve analysis
• Experience with CI/CD pipelines and test automation integration
• Knowledge of common communication protocols (SPI, I2C, UART, CAN, Ethernet)
• Experience mentoring or leading junior engineers
• Background in medical devices, industrial systems, or regulated environments
• Familiarity with test case management tools

Why This Role Matters

You'll be joining at a pivotal time as we scale our test engineering capability to match our ambitious product roadmap. Your expertise will directly impact our ability to deliver reliable, high-quality systems to customers. This is an opportunity to build something meaningful, shape test engineering practices from the ground up, and leave your technical leadership mark on the organization.

Location: Hybrid role based in our R&D lab in Glendale, WI - primarily on-site work with flexibility.
