Test System Software Engineer (Python)

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 bydeliveringwell-designed,reliableand scalable automated test systems.

We work withinternally developedtestplatforms, multipleproduction 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 withother engineering and manufacturing teams to ensure proper system integration.

Role Overview

As aTest System Software Engineer, you will work at the intersection of software, hardware, and manufacturing. You willbe responsible fordeveloping,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 automationsand 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 orsoftware-onlytesting role. The position focuses on production testautomationtool development withhardware interaction, and manufacturing support.

Responsibilities

You willbe responsible for:

• Maintaining and troubleshooting automated test systems used on production lines

• Working closely with production teams to investigate test failures

• Performingrootcauseanalysis acrosssoftware,hardware, and test infrastructure

• Improving the test system based on failure analysis

• Developing andmaintaininginternal software tools, including:

• Testtool platformsandassociatedautomation 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, andlongtermevolution

• 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

• SupportingadditionalR&D and automation initiatives based on business needs and personal initiative

You should have:

Essential

• 3+ years ofhands-onsoftware developmentexperience

• Strongproficiencyin Python for automation, including writing maintainable test code, interacting with hardware drivers, and troubleshooting issues

• Ability to understand complex systems and simplify them into robust, maintainable solutions

Desirable

• Experiencedeveloping,maintaining, or supporting automated test systems in a manufacturing environment
• Solid understanding of digital electronics fundamentals

• Working knowledge ofdigital communication interfaces e.g. CAN, SPI, I²C,Modbus etc.

• 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

• Basicproficiencywith Linuxcommand-linetools

• Working knowledge of SQL

Personal Attributes

• Have a positivecan-doattitude toward technical challenges

• Be proactive and continuously look for opportunities to improve systems and processes

• Communicate clearly and effectively with colleagues acrossdisciplines

• Have a strong i
