Job description

The Team

Our team specializes in automated testing across multiple stages of product assembly. We support testing from low-level PCBA validation through intermediate assembly stages up to final End-of-Line (EOL) testing. Our mission is to ensure and continuously enhance product quality by delivering well-designed, reliable and scalable automated test systems.

We work with internally developed test platforms, multiple production test stations tailored to the specific test scope, a global test results database, data visualization and analysis tools, and a growing set of drivers controlling measurement equipment and test hardware.

We cooperate with other engineering and manufacturing teams to ensure proper system integration.

Role Overview

As a Test System Software Engineer, you will work at the intersection of software, hardware, and manufacturing. You will be responsible for developing, maintaining, and improving production test systems while working closely with production teams to diagnose and resolve issues on the manufacturing line.

You will have a direct impact on manufacturing yield, failure detection, and production throughput. Your automations and data tooling will be used daily on the production line, making the difference between manual firefighting and predictable, scalable manufacturing.

This is not a QA or software-only testing role. The position focuses on production test automation tool development with hardware interaction, and manufacturing support.

Responsibilities

You will be responsible for:

• Maintaining and troubleshooting automated test systems used on production lines
• Working closely with production teams to investigate test failures
• Performing rootcause analysis across software, hardware, and test infrastructure
• Improving the test system based on failure analysis
• Developing and maintaining internal software tools, including:
• Test tool platforms and associated automation frameworks (Python)
• Test data storage, visualization, and analysis tools (SQL, Grafana)
• Clear and maintainable technical documentation
• Taking ownership of test systems deployed on production lines, including their reliability, maintainability, and longterm evolution
• Continuously improving manufacturing and test processes, with focus on robustness, execution time, and scalability
• Replacing legacy test solutions with modern, maintainable architectures
• Collaborating with colleagues from test engineering, R&D, mechanical and electrical engineering, and production line teams
• Supporting additional R&D and automation initiatives based on business needs and personal initiative

You should have:

• 3+ years of hands-on software development experience
• Strong proficiency in Python for automation, including writing maintainable test code, interacting with hardware drivers, and troubleshooting issues
• Solid understanding of digital electronics fundamentals
• Ability to understand complex systems and simplify them into robust, maintainable solutions
• Experience developing, maintaining, or supporting automated test systems in a manufacturing environment
• Understanding of best practices in manufacturing environments
• Hands - on experience with test and measurement equipment such as oscilloscopes, signal generators, and data acquisition systems
• Familiarity with CI/CD pipelines for test software
• Proficient in the creation of technical documentation
• Basic proficiency with Linux command-line tools
• Working knowledge of SQL

Personal Attributes

• Have a positive can-do attitude toward technical challenges
• Be proactive and continuously look for opportunities to improve systems and processes
• Communicate clearly and effectively with colleagues across disciplines
• Have a strong instinct for thoughtful automation and system simplification
• Quality focused with good attention to detail
• Self-driven, eager to learn and develop as a valued member of the team

Our Values

• We work together
• We believe in people
• We won’t accept the ‘way it has always been done’
• We listen to learn
• We’re trying to do the right thing
